Description

  The present invention relates to an input device that generates and outputs a command for an operation target device.

  A car navigation system having functions such as an audio device and an AV (audiovisual) device includes an input device having a plurality of buttons. The car navigation system in practical use has a complicated structure as the number of buttons, in other words, the number of parts increases, and the device becomes larger. Therefore, a small number of buttons are used to reduce the size of the device. Different operation commands can be input. Specifically, the input device is configured to be capable of inputting an operation command by hierarchizing a plurality of operation commands and selecting a user-desired operation command from the hierarchized operation commands. Yes. Even in this case, the convenience as an input device is improved by providing buttons corresponding to the operation commands on a one-to-one basis for frequently used operation commands.

  In the conventional input device, a command for operating the system is assigned to the fingerprint, the user's fingerprint is identified to identify the command assigned to the identified fingerprint, and the identified command Is notified to the system. In particular, the finger operated by the user is identified by identifying the fingerprint, and the process to be performed by the system is designated based on the identification result. Thus, the number of buttons provided in the input device is suppressed by causing each finger of the user to function as a button (see, for example, Patent Document 1).

JP 2003-163762 A

  Since a plurality of operations are required to select a desired operation command from a plurality of hierarchical operation commands, there is a problem that the operation of inputting the operation command becomes complicated.

  Further, when each finger of the user is made to function as a button by specifying the finger operated by the user, there is a problem that only the operation command of the number of fingers can be specified at the maximum.

  Accordingly, an object of the present invention is to provide an input device capable of reducing the number of parts and generating and outputting a plurality of different commands with an easy operation.

  According to the present invention (1), the determination unit determines the finger type by comparing the finger pressure-sensitive on the touch panel with the biological information stored in the storage unit. Thereby, when the finger | toe corresponding to the biometric information memorize | stored in a memory | storage means senses pressure on a touch panel, the kind of finger | toe is specified. The determination unit determines whether or not the finger movement detected by the touch panel matches the trajectory information stored in the storage unit. In this way, it is determined whether or not the finger is moved on the surface of the touch panel so as to match the trajectory information stored in the storage unit with the specific finger stored in the storage unit.

  When the finger type is determined by the determining unit and the detected finger movement matches the trajectory information, the command generating unit determines the finger type determined by the determining unit and the finger type detected by the touch panel. Generates and outputs a command corresponding to the movement. In this way, on the surface of the touch panel, the user generates a command corresponding to the movement only by moving the finger that matches the trajectory information stored in the storage unit with a specific finger stored in the storage unit. Is output.

  According to the present invention (1), on the surface of the touch panel, the user simply moves the finger that matches the trajectory information stored in the storage unit with the specific finger stored in the storage unit. A command corresponding to is generated and output. This makes it possible to easily input a command intended by the user without performing a complicated operation. In addition to the types of fingers, commands corresponding to the movement of the finger are generated, so it is possible to input different commands that are more than the number of fingers according to the movement of the finger, and the number of buttons, that is, the number of parts Reduction can be achieved.

  Hereinafter, a plurality of embodiments for carrying out the present invention will be described with reference to the drawings. However, the technical scope of the present invention is not limited to these embodiments, but extends to the invention described in the claims and equivalents thereof. Parts corresponding to the matters described in the preceding forms in each embodiment are denoted by the same reference numerals, and overlapping description may be omitted. When only a part of the configuration is described, the other parts of the configuration are the same as those described in the preceding section. Not only the combination of the parts specifically described in each embodiment, but also the embodiments can be partially combined as long as the combination does not hinder.

  FIG. 1 is a block diagram showing a car navigation system 2 including an input device 1 according to an embodiment of the present invention. The car navigation system 2 includes a display unit 3, an input determination unit 4, a drawing control unit 5, a process execution unit 6, a speaker 7, and a control unit 8.

The control means 8 is a central processing unit (Central
Processing Unit: CPU (ROM) is ROM (Read Only Memory) and RAM (Random
It is realized by executing a control program stored in a storage means realized by an access memory or the like, and controls each means constituting the car navigation system 2.

  The display unit 3 functions as the display 9 that displays the image information given from the drawing control unit 5 on the display screen, and also functions as the touch panel 11. The touch panel 11 detects absolute coordinate values on the display screen of the finger that presses the display screen of the display unit 3. The touch panel 11 is realized using, for example, an analog resistance film method. The touch panel 11 can detect the absolute coordinate value of the finger on the display screen at a predetermined time interval, and can detect the trajectory of the finger movement on the display screen based on the time change of the absolute coordinate value. In addition, the touch panel 11 can detect a time from when the user's finger presses the display screen until the display screen is separated (hereinafter referred to as a pressing time). The touch panel 11 provides the instruction generation unit 12 of the input determination unit 4 with the detected absolute coordinate value of the finger on the display screen, trajectory information indicating the movement of the finger, and pressing time information indicating the pressing time.

  Further, the touch panel 11 is configured to be able to acquire finger biometric information. In the present embodiment, the touch panel 11 acquires a fingerprint image representing a fingerprint of a finger pressing the display screen as biometric information. For example, the fingerprint image is an optical type that emits light toward the finger and receives the reflected light reflected by the finger, or the difference in the distance from the display screen caused by the unevenness of the fingerprint is a change in capacitance. It can be obtained using a capacitance type that is detected based on the capacitance type. The touch panel 11 is configured to be able to acquire a fingerprint image of a finger placed on any area of the display screen. The touch panel 11 gives the acquired fingerprint image to the command generation unit 12 of the input determination unit 4.

  The input determination unit 4 includes an instruction generation unit 12 that functions when the CPU executes the control program stored in the storage unit, and the instruction generation unit 12 reads or writes data stored in the storage unit. A fingerprint determination table 31, a locus determination table 32, a pressing time determination table 33, and an operation command correspondence table 34 that function according to the above. The command generation unit 12 corresponds to a determination unit and a command generation unit. The determination unit compares a fingerprint image of a finger that is pressure sensitive to the touch panel 11 with a fingerprint image that is biometric information stored in the storage unit to determine the type of the finger, and the movement and storage of the finger detected by the touch panel 11 It is determined whether or not the trajectory information stored in the means matches. The command generation means corresponds to a command corresponding to the finger type and the finger movement detected by the touch panel 11 when the finger type is determined and the detected finger movement matches the trajectory information. Generate and output an operation command.

  One or a plurality of fingerprint images are registered in the fingerprint determination table 31. The command generation unit 12 collates the fingerprint image registered in the fingerprint determination table 31 with the fingerprint image provided from the touch panel 11 and specifies the type of finger to be pressure-sensitive on the display screen if there is a matching fingerprint image. For example, when “left index finger” is being pressed on the display screen, the command generation unit 12 specifies that the finger to be pressure-sensitive on the display screen is “left index finger”. The command generation unit 12 assigns “1” to a fingerprint flag described later if there is a matching fingerprint image when collating the fingerprint image, and sets “0” to a fingerprint flag described later if there is no matching fingerprint image. substitute. Fingerprint matching is a feature point extraction that extracts relative positional relationships such as the end points of bulges (ridges) and branching points as feature information as feature information and compares the feature information. This is performed by a collation method (maneuver method) or an image matching method (pattern matching method) in which fingerprints are collated by directly comparing fingerprint images.

  One or more pieces of locus information are registered in the locus determination table 32. The command generation unit 12 collates trajectory information representing finger movement given from the touch panel 11 with trajectory information registered in the trajectory determination table 32. The instruction generation unit 12 substitutes “1” for a trajectory flag described later if there is a matching trajectory, and substitutes “0” for the trajectory flag if there is no matching trajectory.

  In the pressing time determination table 33, one or more predetermined ranges of pressing times are registered. The pressing time in the predetermined range has a time width of about 1 second, for example, 2 to 3 seconds, 3.5 to 4.5 seconds, and 5 to 6 seconds. The command generation unit 12 collates the pressing time represented by the pressing time information given from the touch panel 11 with the pressing time registered in the pressing time determination table 33. If the pressing time indicated by the pressing time information given from the touch panel 11 is within one or more predetermined ranges of pressing times registered in the pressing time determination table 33, the command generation unit 12 sets a pressing time flag to be described later. “1” is substituted, and “0” is substituted into the pressing time flag if the pressing time is outside the predetermined range.

  In the operation command correspondence table 34, at least one of finger type, trajectory information, and pressing time information and a specific operation command are registered correspondingly.

  The command generation unit 12 refers to the operation command correspondence table 34 and represents the fingerprint image and the movement of the finger based on the control information indicating the current control state given from the distribution management unit 24 of the drawing control means 5 described later. Of the trajectory information and the pressing time information, an operation command corresponding to information matching the information registered in each determination table 31, 32, 33 is generated and output to the command receiving unit 13 of the processing execution means 6 for giving. .

  The process execution unit 6 includes a command receiving unit 13 that functions when the CPU executes the control program stored in the storage unit, and an operation target control unit 21 that performs control based on an operation command from the command receiving unit 13. And an amplifier (hereinafter referred to as AMP) 22.

The operation target control unit 21 receives a CD (Compact Disc) based on the operation command from the command receiving unit 13.
) CD control unit 14 functioning as a device, DVD control unit 15 functioning as a DVD (Digital Versatile Disk) device, HDD control unit 16 functioning as an HDD (Hard Disk Drive) audio device, and television (TV) device The TV control unit 17 that functions as a radio control unit, a radio control unit 18 that functions as a radio device, and a NAVI control unit 19 that functions as a car navigation device.

  The operation target control unit 21 executes processing based on the operation command given from the command receiving unit 13, image information to be displayed on the display unit 3, audio information representing sound output from the speaker 7, and the current control state Is generated and given to the drawing control means 5. The AMP 22 amplifies an electrical signal given as audio information from the drawing control means 5 and outputs the amplified signal to the speaker 7, and causes the speaker 7 to output the audio information as sound.

  The drawing control unit 5 includes a drawing engine 23 and a distribution management unit 24 that function when the CPU described above executes a control program stored in the storage unit.

  The distribution management unit 24 generates image information to be displayed on the display unit 3 based on the image information, the sound information, and the control information given from the operation target control unit 21 and gives the image information to the drawing engine 23, and the speaker. The voice information representing the voice to be output from the control unit 7 is given to the AMP 22 as an electrical signal, and the control information representing the current control of the operation target control unit 21 is given to the command generation unit 12. The drawing engine 23 gives the image information given from the distribution management unit 24 to the display 9 as an electrical signal, and displays the image information on the display screen.

  FIG. 2 is a flowchart showing processing for registering a fingerprint image in the fingerprint determination table 31. FIG. 3 is a diagram illustrating an image displayed on the display screen of the display unit 3 when processing for registering a fingerprint image in the fingerprint determination table 31 is performed.

  The car navigation system 2 has a plurality of operation modes. An operation mode for registering a user's fingerprint in the fingerprint determination table 31 is called a fingerprint registration mode. When the user of the car navigation system 2 selects the fingerprint registration mode by pressing the touch panel 11 based on the guidance screen displayed on the display screen of the display means 3, the process of registering the fingerprint image starts and the process proceeds to step a1. Transition.

  When the fingerprint registration mode is selected, the display 9 first displays a selection screen for selecting whether to register a right-hand or left-hand fingerprint image on the display screen based on the image information given from the drawing engine 23. For example, an area on the display screen to be pressed when the right hand is selected and an area on the display screen to be pressed when the left hand is selected are displayed. In step a1, the control means 8 determines whether or not the right hand has been selected. If the right hand is selected, the process proceeds to step a2. If the right hand is selected, that is, if the left hand is selected, the process proceeds to step a3. Whether the right hand or the left hand is selected is determined by detecting an absolute coordinate value when the user presses the display screen according to the selection screen. When the right hand is selected and the process proceeds to step a2, the control means 8 selects a right hand UI (User Interface), displays the right hand UI on the display screen, and proceeds to step a4. When the right-hand UI is selected, a right-hand UI display screen is displayed in steps after step a4. When the left hand is selected in step a1 and the process proceeds to step a3, the control means 8 selects the left hand UI, displays the left hand UI on the display screen, and proceeds to step a4. When the left-hand UI is selected, the left-hand UI is displayed on the display screen in steps after step a4.

  FIG. 3A is a diagram showing a display screen when the left-hand UI is selected in step a3. When the left hand UI is selected in step a3 and the left hand UI is displayed on the display screen, the display 9 displays “the little finger, ring finger, middle finger, index finger at the display position based on the image information given from the drawing engine 23. Is displayed, and the four placement areas 25 on which the four fingers other than the thumb of the left hand are to be placed are displayed.

  In step a4, the control means 8 controls the touch panel 11 to read the fingerprint images of the four fingers excluding the thumb, and proceeds to step a5. In step a5, the control means 8 determines whether or not the fingerprint image has been normally read based on the read fingerprint image. Move to a6. For example, if a fingerprint image is read in a state where no finger is placed on at least one of the four placement areas 25, the fingerprint image cannot be read normally. If the fingerprint image cannot be read normally as described above, the process proceeds to step a7. In step a7, in order to read the fingerprint image normally, the display 9 displays the operation assistance information that assists the user with respect to the input device 1 by notifying the user that the fingerprint could not be read. Display cautions to be displayed. Specifically, the display 9 displays character information “The fingerprint is not input correctly” on the display screen. This can prompt the user to place a finger on the placement area 25. When the caution display is performed in step a7, the process proceeds to step a4 again, and the processes of step a4, step a5 and step a7 are repeated until the fingerprint image can be read correctly.

  In step a6, since the fingerprint images of the four fingers other than the thumb are read normally in step a4, the command generation unit 12 registers the read fingerprint image in the fingerprint determination table 31 and proceeds to step a8. To do.

  FIG. 3B is a diagram illustrating a display screen after registration of the fingerprint image is completed in step a6. When the registration of the fingerprint image is completed, the display 9 displays the character information “Put your thumb on the display position” based on the image information given from the drawing engine 23 and place the thumb of the left hand on it. The placement area 26 to be displayed is displayed.

  In step a8, the control means 8 controls the touch panel 11 to read the thumb fingerprint image and proceeds to step a9. In step a9, the control means 8 determines whether or not the fingerprint image has been successfully read based on the read fingerprint image. If it is determined that the fingerprint image has been read normally, the control unit 8 Move to a10. For example, if a fingerprint image is read in a state where no thumb is placed on the placement area 26, the fingerprint image cannot be read normally. As described above, when the fingerprint image cannot be read normally, the process proceeds to step a11. In step a11, in order to read the fingerprint image normally, the display 9 performs a caution display notifying the user that the fingerprint could not be read. Specifically, the display 9 displays character information “The fingerprint is not input correctly” on the display screen. This can prompt the user to place the thumb on the placement area 26. When the caution display is performed in step a11, the process proceeds to step a8 again, and the processes of step a8, step a9 and step a11 are repeated until the fingerprint image is correctly read.

  In step a10, since the thumb fingerprint image is normally read in step a8, the control means 8 registers the read thumb fingerprint image in the fingerprint determination table 31 and proceeds to step a12.

  In step a12, the command generation unit 12 determines whether the fingerprint image registered in step a6 and step a10 is a new fingerprint image not registered in the fingerprint determination table 31, and if it is an unregistered fingerprint image. If so, the process proceeds to step a13. In step a13, the display 9 performs a caution display for notifying the user that the fingerprint image has been registered normally. Specifically, the display 9 displays character information “Your fingerprint data has been registered”.

  In step a14, the control means 8 controls the display 9 to acquire the seating position information indicating whether the user is seated in the drive seat or the passenger seat, and the seating position information is obtained from the fingerprint image. At the same time, it is registered in the fingerprint determination table 31. The display 9 includes arm detection sensors at both ends in the vehicle width direction when the car navigation system 2 is mounted on the vehicle. When the user sits in the driver's seat and presses the touch panel 11 with a finger, the arm is detected by the arm detection sensor provided near the driver's seat, and sits in the passenger seat and presses the touch panel 11 with the finger. In this case, since the arm portion is detected by the arm portion detection sensor provided near the passenger seat, the display 9 can acquire the seating position information based on the detection result of the arm portion detection sensor. This arm part detection sensor is realized by, for example, an infrared sensor that detects infrared rays emitted from the user's body. When the seating position information is registered, this process ends.

  FIG. 3C is a display screen for notifying the user that registration of the fingerprint image in the fingerprint determination table 31 has been completed normally. When the registration of the fingerprint image in the fingerprint determination table 31 is normally completed in step a14, the display 9 outputs the image shown in FIG. 3 (3) to the display screen and ends the process of registering the fingerprint image.

  In step a12, when the command generation unit 12 determines that the fingerprint image registered in step a6 and step a10 is a fingerprint image already registered in the fingerprint determination table 31, the process proceeds to step a16. In step a16, the display 9 performs caution display for notifying the user that the fingerprint image to be registered is already registered based on the image information given from the drawing engine 23. Specifically, the display 9 displays character information “Your fingerprint data has already been registered” and proceeds to step a17. In step a17, in order to prevent duplicate registration of fingerprint images, the fingerprint images registered in the fingerprint determination table 31 in steps a6 and a10 are erased, and the processing for registering the fingerprint image ends.

  By performing the processing described above, a fingerprint image can be registered in the fingerprint determination table 31. In particular, the input device 1 functions as an input interface for registering a fingerprint image by displaying a placement area where each finger is to be placed on the display screen, so that the user can select a finger corresponding to the placement area. The fingerprint image of each finger can be registered simply by placing the. Thus, it is possible to save time and effort for the user to sequentially input which finger fingerprint the read fingerprint image corresponds to. Since all the fingerprint images of the five fingers are registered in this way, by referring to the fingerprint determination table 31, it is possible to determine the type of finger that the touch panel 11 senses pressure, that is, with which finger the user pressed the display screen. Can do.

  FIG. 4 is a schematic diagram showing a hierarchical structure of modes. In the car navigation system 2 according to the present embodiment, modes representing specific operation processes are hierarchized. There are four modes in the top floor mode: a map mode 51, an AV operation mode, a telephone mode, and a G-Book mode. Further, a destination search mode 52 and a traffic information display mode 53 are provided below the map mode 51. Further, below the destination search mode 52 are a mode 54 for searching from place names, a mode 55 for searching from genres, a mode 56 for searching from telephone numbers, and the like. Since the modes are hierarchized in this way, each mode except the top floor mode is associated with the upper layer mode. For example, the search mode 54 based on the place name is associated with the map mode 51 and the destination search mode 52 in this order.

  In order to input an operation command for selecting the search mode 54 from the place name, the map mode 51, the destination search mode 52, and the search mode 54 from the place name can be selected in this order. By associating the finger operation on the screen with the mode 54 for searching from the place name, it is possible to easily input an operation command for selecting the mode 54 for searching from the place name.

  FIG. 5 is a flowchart showing a process of registering the operation of the finger on the display screen in association with the operation command in the operation command correspondence table 34. FIG. 6 is a diagram showing a display screen when processing for registering the operation of the finger on the display screen and the operation command in the operation command correspondence table 34 is performed.

  In this embodiment, as an example, a mode to be registered is selected based on a display screen of a mode (hereinafter referred to as an operation registration mode) for registering a finger operation on the display screen in association with an operation command. Processing will be described. When the user inputs to select a mode to be registered in accordance with an instruction on the display screen of the operation registration mode, a process of registering in the operation command correspondence table 34 starts and the process proceeds to step b1.

  FIGS. 6 (1) to 6 (3) are diagrams showing display screens when the mode 54 for searching from place names is selected as an example. First, when the user selects an operation registration mode from a plurality of menus displayed on the display screen, the operation registration mode is displayed, and the operation registration screen shown in FIG. 6A is displayed. When selecting a mode, the display area of the icon indicating the mode is pressed on the display screen, and in order to display the mode below the mode, the display area of the arrow extending from each mode is pressed. First, in order to display a mode below the map mode 51, when the user presses an arrow 36 extending from the icon 35 indicating the map mode 51 (a right-pointing arrow in FIG. 6A), the user is shown in FIG. A screen of a mode below the map mode 51 is displayed. When the user presses an arrow (an arrow pointing to the right in FIG. 6 (2)) 38 extending from the icon 37 indicating the destination search mode 52 in order to display a mode below the destination search mode 52, FIG. The screen of the mode below the destination search mode 52 shown in FIG. Next, in order to select the mode 54 for searching from the place name, the display area of the icon 39 indicating the mode 54 for searching from the place name is pressed. In this way, the mode 54 for searching from the place name is selected and input to the car navigation system 2.

  In step b1, the control means 8 reads information representing the input mode selection, and proceeds to step b2. In step b2, the control means 8 refers to the operation command correspondence table 34 to determine whether or not a finger operation corresponding to the selected mode has already been registered. If not registered, the process proceeds to step b5.

  In step b3, the display 9 informs that the operation corresponding to the selected mode is already registered based on the image information given from the drawing engine 23, and is there an intention to re-register this mode? A caution display is displayed to let the user select whether or not. Specifically, the display 9 displays character information “The operation mode has already been registered for the selected mode ΔΔ. Do you want to re-register?”. At this time, the display 9 displays character information indicating “re-register” and “not re-register” on the display screen. Next, the process proceeds to step b4. In step b4, the control means 8 determines whether or not to re-register the selected mode. When re-registering, the process proceeds to step b5. When not re-registering, it transfers to step b1 and repeats the process which selects the mode which should be registered again. The determination as to whether or not to re-register by the control means 8 is made based on which display area “re-register” or “not re-register” displayed on the display screen is pressed by the user.

  In step b5, the touch panel 11 reads the movement of the finger on the display screen and proceeds to step b6. At this time, the touch panel 11 reads the finger movement on the display screen and also reads the fingerprint image. In step b6, the control means 8 determines whether or not the user has completed the input of the finger movement on the display screen. If the input has not been completed yet, the control means 8 proceeds to step b5 and reads the finger movement. Continue processing. In step b6, when the control means 8 determines that the user has completed the input of the finger movement on the display screen, the process proceeds to step b7.

  6 (4) and 6 (5) are images displayed on the display screen of the display means 3 when reading a finger movement on the display screen. One of the longitudinal directions of the display screen of the display means 3 is defined as leftward, and the other of the longitudinal directions is defined as rightward. One of the vertical direction perpendicular to the thickness direction of the display means 3 and the longitudinal direction of the display screen of the display means 3 is defined as upward, and the other in the vertical direction is defined as downward. The display 9 displays a region 42 where a finger operation to be registered is to be performed for the user, and notifies an instruction to perform a finger operation to be registered in the region 42. The user moves the finger to be registered while pressing the display screen in the area 42 where the registration operation is to be performed, and then presses the display area representing “OK”. When the display area representing “OK” is pressed, the control means 8 determines that the input of the finger movement has been completed.

  In step b8, the command generator 12 performs input analysis for analyzing the read finger movement and finger type. Specifically, the command generation unit 12 compares the fingerprint image read in step b5 with the fingerprint image registered in the fingerprint determination table 31, and determines the type of finger that pressed the touch panel 11. That is, it is determined which finger of the left or right hand has pressed the area 42 where the finger should be operated. In addition, the command generation unit 12 expresses the movement of the finger on the display screen using four directions of up, down, left, and right on the plane. For example, the direction of the tangent line of the finger trajectory is approximated to one of four directions, up, down, left, and right. For example, it is determined that the trajectory of the finger movement drawn in the region 42 to be registered in FIG. 6 (5) follows the trajectory in the right (→) direction following the trajectory in the downward (↓) direction. be able to.

  In step b8, the display 9 displays the result of the input analysis based on the image information given from the drawing engine 23 as a caution display. Specifically, the display 9 displays character information “An operation of □□ was performed with a ○ finger”. In the example shown in FIG. 6 (5), the display 9 displays the character information “The operation of ↓ → was performed with the middle finger”, and a series of downward (↓) direction and right (→) direction with the middle finger. It is notified that the operation of the finger is performed. Next, the process proceeds to step b9.

  In step b9, the command generation unit 12 refers to the operation command correspondence table 34 to determine whether or not the operation command corresponding to the finger operation analyzed in step b7 has already been registered, and has already been registered. Then, the process proceeds to step b10. In step b10, the display 9 informs the user that an operation command corresponding to the same operation as the finger operation already registered in the operation command correspondence table 34 already exists based on the image information given from the drawing engine 23. At the same time, a caution display that prompts the user to input whether or not to register this finger operation in the operation command correspondence table 34 corresponding to the present mode selected in step b1 is performed. Specifically, the display 9 displays character information “Same operation is registered in mode XX. Do you want to register the operation in this mode?”, And the process proceeds to step 11. In step b11, the control means 8 determines whether or not to register the finger operation and the finger type analyzed in step b7 for this mode. If not, the control means 8 proceeds to step b5. Read the finger movement again. As a result, it is possible to prevent a plurality of different operation commands from being registered in the operation command correspondence table 34 corresponding to the operation of one finger.

  In step b11, when the control means 8 determines that the finger operation analyzed in step b7 is registered in the operation command correspondence table 34 for this mode, the process proceeds to step b12. The determination of the control means 8 in step b11 is made based on the user's operation on the display screen.

  In step b12, the control means 8 invalidates the mode already registered in the operation command correspondence table 34 corresponding to the finger operation analyzed in step b7, and proceeds to step b13. In step b13, the display 9 performs a caution display for notifying the invalidated mode operation. Specifically, the display 9 displays character information indicating that “mode XX operation has been disabled”, and proceeds to step b14.

  When the command generation unit 12 determines that an operation not registered in the operation command correspondence table 34 is input in step b9, the process proceeds to step b14.

  FIG. 6 (6) shows a display screen for confirming whether or not this mode and the finger operation analyzed in step b7 are registered in the operation command correspondence table 34 in correspondence with each other. When the user presses the display area displaying “OK” on the display screen, in step b14, the command generation unit 12 associates the present mode with the operation of the finger analyzed in step b7 to match the operation command correspondence table 34. And the finger operation analyzed in step b7 is registered as trajectory information in the trajectory determination table 32, and the process proceeds to step b15. In step b15, the display 9 performs caution display for notifying the registered operation and an operation command corresponding to the operation based on the image information given from the drawing engine 23. Specifically, the display 9 displays the character information “Owner's finger operation □□ registered in mode △△”, and operates the finger operation on the display screen in correspondence with the operation command. The process of registering in the instruction correspondence table 34 is terminated.

  FIG. 6 (7) is a display screen showing a caution display for notifying the registered operation and the operation command corresponding to this operation.

  By performing the processing described above, the operation of the finger on the display screen and the operation command can be registered in the operation command correspondence table 34 in association with each other. In the present embodiment, the process of registering the finger type / finger movement and the operation command in association with the operation command correspondence table 34 has been described, but three types of information, the finger type, the trajectory information, and the pressing time information, are described. At least one of them can be selected, and the selected information can be registered in the operation command correspondence table 34 in association with the operation command. For example, by adding the pressing time to the finger type and finger movement, the finger type, finger movement, and the pressing time required for the finger movement are registered in the operation command correspondence table 34 in association with the operation command. Can do. Specifically, when input analysis is performed in step b7, in addition to the finger type and finger movement, the pressing time information is also acquired from the touch panel 11, and the finger type, trajectory information, and pressing information are obtained for this mode. Corresponding time information is registered in the operation command correspondence table 34. Further, for example, an operation command can be associated with only the pressing time information and registered in the operation command correspondence table 34.

  In addition, as an example of the implementation, the processing when registering the trajectory information for the movement of one finger has been described. For example, when a plurality of fingers are simultaneously pressed on the display screen, the types of fingers are associated with the operation commands It is also possible to register it in the operation command correspondence table 34. Furthermore, by pressing a plurality of fingers simultaneously on the display screen, finger operations on the display screens of the plurality of fingers can also be registered in the operation command correspondence table 34 as locus information corresponding to the operation commands.

  In the input device 1 according to the present embodiment, a finger type is authenticated based on biometric information, an operation command is input based on the finger type, and a finger movement on the touch panel 11 is performed regardless of the finger type. There is a normal input mode in which an operation command is input based on this. Specifically, there are a fingerprint input mode in which a finger type is authenticated based on a fingerprint image, and an operation command is input based on the authenticated finger type, and a normal input mode. The normal input mode and the fingerprint input mode can be switched by the user performing a specific operation. In input device 1 of the present embodiment, touch panel 11 includes a button for switching between a normal input mode and a fingerprint input mode. Specifically, this button is realized by providing a display area for displaying the button on the display screen, and the touch panel 11 sensing pressure of the user's finger in the display area.

  FIG. 7 is a flowchart showing a process of generating an operation command based on this operation when the user operates a finger on the display screen. When the user presses the display screen in the fingerprint input mode and the touch panel 11 senses pressure, the process proceeds to step c1. In step c1, the touch panel 11 reads the fingerprint image and gives it to the command generation unit 12, and proceeds to step c2. In step c2, the command generator 12 determines a fingerprint. Specifically, the command generation unit 12 refers to the fingerprint image registered in the fingerprint determination table 31, authenticates the read fingerprint image, and proceeds to step c3. In step c3, the command generation unit 12 determines whether or not the read fingerprint image matches one fingerprint image of one or more fingerprint images registered in the fingerprint determination table 31. If there is a fingerprint image, the process proceeds to step c4, and if there is no matching fingerprint image, the process proceeds to step c5.

  In step c4, the command generator 12 substitutes a numerical value “1” for the fingerprint flag. This fingerprint flag indicates that the fingerprint image read when the value is “1” matches the fingerprint image registered in the fingerprint determination table 31, and the fingerprint image read when the value is “0”. This indicates that the fingerprint image does not match the fingerprint image registered in the fingerprint determination table 31. Next, the process proceeds to step c7.

  If the read fingerprint image does not match the fingerprint image registered in the fingerprint determination table 31 and the process proceeds to step c5, the control unit 8 shifts from the fingerprint input mode to the normal input mode. In this way, when the fingerprint image does not match the registered fingerprint image and the finger type cannot be determined, the input device 1 functions as an input device including a normal touch panel. For example, even when the display screen is pressed by a stick-like object that is not a finger, the input device 1 functions as an input device including a normal touch panel. Next, proceeding to step c6, the command generation unit 12 substitutes “0” for the fingerprint flag. Next, the process proceeds to step c7.

  In step c7, the command generation unit 12 reads the user's trajectory information given from the touch panel 11 and determines the trajectory information. Specifically, the trajectory information representing the trajectory of the user's finger that traces the display screen from when the user's finger presses the display screen until it is separated, and the trajectory information of the finger registered in the trajectory determination table 32 Is matched. Next, the process proceeds to step c8. In step c8, the command generation unit 12 determines whether or not the read trajectory information matches any one of the trajectory information registered in the trajectory determination table 32, and if there is matching trajectory information. The process proceeds to step c9, and if there is no matching trajectory information, the process proceeds to step c10.

  In step c9, the instruction generator 12 substitutes a numerical value “1” for the trajectory flag. This trajectory flag indicates that the trajectory read when the value is “1” matches the trajectory information registered in the trajectory determination table 32, and the trajectory read when the value is “0” is the trajectory determination. This indicates that the trajectory registered in the table 32 does not match. Next, the process proceeds to step c11. In step c10, the instruction generator 12 substitutes “0” for the trajectory flag and proceeds to step c11.

  In step c11, the command generation unit 12 reads the pressing time information given from the touch panel 11 and determines the pressing time. Specifically, it is determined whether or not the time from when the user's finger presses the display screen until the user's finger is separated is within a predetermined range of pressing time registered in the pressing time determination table 33. Next, the process proceeds to step c12, where the command generation unit 12 determines whether or not the read pressing time is within a pressing time within a predetermined range registered in the pressing time determination table 33, and the pressing time within the predetermined range. If it is within the predetermined range, the process proceeds to step c13, and if it is outside the predetermined range, the process proceeds to step c14.

  In step c13, the instruction generating unit 12 assigns a numerical value “1” to the pressing time flag and proceeds to step c15. The pressing time flag indicates that the pressing time read when the value is “1” is within the pressing time within a predetermined range registered in the pressing time determination table 33 and matches the registered pressing time. The pressing time read when the value is “0” is outside the pressing time within a predetermined range registered in the pressing time determination table 33 and does not match the registered pressing time. In step c14, the instruction generating unit 12 assigns a numerical value “0” to the pressing time flag and proceeds to step c15.

  In step c15, the instruction generation unit 12 refers to the operation instruction correspondence table 34 and generates an operation instruction. Specifically, the command generation unit 12 generates an operation command registered in the operation command correspondence table 34 based on the registered fingerprint image, the track information, and the press time based on the fingerprint flag, the track flag, and the press time flag. And output to the command receiving unit 13.

  Table 1 is a table showing the correspondence relationship between the values of the fingerprint flag, the trajectory flag, and the pressing time flag and the information referred to in step c15.

  For example, when all the values of the fingerprint flag, the pressing time flag, and the trajectory flag are “0”, the user's finger operation on the display screen does not match any of the registered fingerprint image, the trajectory information, and the pressing time. Therefore, the command generation unit 12 generates an operation command based on the absolute coordinate value on the display screen when the user simply presses the display screen. For example, when all the values of the fingerprint flag, the pressing time flag, and the trajectory flag are “1”, the user's finger operation on the display screen is applied to all the registered fingerprint images, the trajectory information, and the pressing time. Since they match, the command generation unit 12 generates an operation command based on the type of finger operated on the display screen, the trajectory of the finger, and the pressing time.

  When the command generation unit 12 generates an operation command and outputs it to the command reception unit 13, the process of generating the operation command is terminated.

  According to the input device 1 of the present embodiment described above, when the command generation unit 12 generates an operation command and outputs the operation command to the command reception unit 13, the command reception unit 13 operates based on the given operation command. The control unit 21 is controlled. Thereby, the car navigation system 2 performs processing based on the operation of the finger on the display screen of the user. In this way, the user can easily input an operation command intended by the user without performing a complicated operation only by performing a specific operation on the display screen. Also, not only the type of finger but also an operation command corresponding to the movement of the finger is generated, so that it becomes possible to input an operation command different from the number of fingers according to the movement of the finger, and the number of buttons is suppressed. be able to. Therefore, it is possible to realize the input device 1 that can reduce the number of parts of the device body and simplify the input operation as much as possible. In addition, since the structure can be simplified by reducing the number of parts, the size of the input device 1 can be reduced.

  In addition, since the operation command is input according to the operation of the finger on the display screen, the user can input the operation command without looking at the display screen. As a result, it is possible to perform other operations with the line of sight other than the display screen while inputting an operation command, and the convenience for the user is improved.

  Further, according to the input device 1 of the present embodiment, it is possible to register the finger operation on the display screen and the operation command in the operation command correspondence table 34 according to the user's preference. For example, a finger operation corresponding to an operation command frequently used by the user can be registered, and convenience for the user is improved.

  Further, according to the input device 1 of the present embodiment, when a caution display for visually displaying operation assistance information for assisting a user's operation on the input device 1 is performed, a fingerprint image and a finger movement are registered. Since the operation to be performed by the user is notified to the input device 1, it is possible to smoothly register a fingerprint image, a finger movement, and the like without being confused by the user.

  Further, according to the input device 1 of the present embodiment, trajectory information that approximates the movement of the finger on the display screen to the movement of the finger in four directions, up, down, left, and right is detected. Since the finger movement on the display screen is expressed in a simplified manner in this way, the user can easily reproduce the finger movement corresponding to the registered trajectory information, and can easily input an operation command. Can do. If the finger movement is registered as trajectory information as it is, an operation command cannot be input unless the registered finger movement is reproduced as it is, and the operation for inputting the operation command becomes complicated.

  In the input device 1 according to the present embodiment, caution display for visually displaying the operation assistance information for assisting the user's operation on the input device 1 is performed. However, the operation assistance information may be output from the speaker 7 as sound. As described above, by outputting the operation assistance information as sound, the user can operate the input device 1 without reading the caution display displayed on the display screen.

Furthermore, the touch panel 11 may include a button for switching whether to output the operation assistance information as a visible display or a sound. When the user presses a button displayed on the display screen, whether or not the operation assistance information is output can be switched according to the user's needs, and the convenience for the user is improved.

  In the input device 1 according to the present embodiment, the finger type is determined by authenticating the fingerprint image. However, the finger type may be determined based on other biological information without being limited to the fingerprint image. For example, the input device 1 may determine the type of finger by performing vein authentication.

  In the above description, the operation command for selecting the mode and the processing for registering the operation of the finger in correspondence with the operation command correspondence table 34 have been described. However, in the input device 1 of the present embodiment, in the specific mode. The operation of the finger to be performed and the operation command corresponding to the operation of the finger can also be registered in the operation command correspondence table 34.

  FIG. 8 is a diagram illustrating a correspondence relationship between a display screen in a specific mode, movement of each finger in each mode, and an operation command corresponding to the movement of the finger. Table 2 is a table showing specific modes, movements of fingers in each mode, and operation commands corresponding to the movements of the fingers. In the input device 1 according to the present embodiment, the specific modes shown in Table 2, the movement of each finger in each mode, and the operation command corresponding to the movement of this finger are associated with each other in the operation command correspondence table 34 in advance. It is registered.

  The correspondence between the finger movement on the display screen and the operation command will be described with reference to Table 2 and FIG.

  FIG. 8A shows the correspondence between the movement of each finger and the operation command in the basic (map) mode. In the basic (map) mode, the surrounding map screen including the current location is displayed on the display screen. For example, when the display screen is pressed with a little finger in this basic (map) mode, an operation command for switching from the basic (map) mode to the source direct mode shown in FIG. 8B is input, and the input mode is switched to the source direct mode. In addition, when the display screen is pressed with the thumb in each mode shown in FIGS. 8A to 8D, an operation command for changing to the basic (map) mode is input, and the mode changes to the basic (map) mode. Therefore, when the display screen is pressed with the thumb in the basic (map) mode, the basic (map) mode is maintained.

  FIG. 8 (2) shows the correspondence between the movement of each finger and the operation command in the source direct mode. In the source direct mode, a surrounding map screen including the current location is displayed on the display screen. The display screen in the source direct mode is the same as the display screen in the basic (map) mode, but in the basic (map) mode, the display screen is changed to the source direct mode by pressing the display screen with a little finger. Whether direct mode or basic (map) mode can be grasped. For example, in this source direct mode, when a thumb or little finger is pressed on the display screen, an operation command for changing from the source direct mode to the basic (map) mode is input, and the mode changes to the basic (map) mode. For example, when a predetermined movement is performed with the ring finger on the display screen in the source direct mode, an operation command for operating the TV control unit 17 is input. When a predetermined movement is performed with the middle finger on the display screen in the source direct mode, an operation command for operating the radio control unit 17 is input. When a predetermined movement is performed with the index finger on the display screen in the source direct mode, an operation command for operating the audio control unit including the CD control unit 14, the DVD control unit 15, and the MD control unit 16 is input.

  Table 3 is a table showing a relationship between a tuner (Radio / TV) operation common to an audio operation, a Radio operation, and a TV operation, a finger movement, and an operation command corresponding to the finger movement.

  For example, when the display screen in the source direct mode is pressed with the middle finger, an operation command for playing or stopping music is input, and when playing back audio information, playback of the audio information is stopped and the audio information is played back. If not, playback of audio information is started. Whether or not the sound information is being reproduced is determined based on control information indicating the current control state given from the distribution management unit 24 to the command generation unit 12. Further, for example, when the finger is moved to the right while pressing the display screen with the middle finger on the display screen in the source direct mode, a track up operation command for moving to the next track is input and moved to the next track. Further, for example, in the source direct mode display screen, when the middle finger is continuously pressed down for a predetermined time (long press) on the display screen, an operation command for switching to the audio playback mode shown in FIG. Transition to mode.

  Further, for example, when the display screen is pressed for a long time with the index finger on the display screen in the source direct mode, the mode changes to the tuner reproduction mode shown in FIG. When the finger is moved to the right while pressing the display screen with the index finger on the display screen in the source direct mode, a channel up operation command for switching up one channel is input, and the channel is switched up one channel. Also, on the source direct mode display screen, if you move your finger to the right while pressing the display screen with your index finger and then press and hold it, an auto preset operation command will be input to raise the channel one by one to the receivable channel. Switch to a receivable channel. Further, when the finger is moved to the left while pressing the display screen with the index finger on the display screen in the source direct mode, a channel down operation command for switching the channel down by one is input, and the channel is switched to the next lower channel. On the source direct mode display screen, move the finger to the left while pressing the display screen with your index finger, and press and hold to input an auto-preset operation command that lowers the channel one by one to the receivable channel. Switch to a receivable channel.

  FIG. 8 (3) shows the correspondence between the movement of each finger and the operation command in the audio playback mode. FIG. 8 (4) shows the correspondence between the movement of each finger and the operation command in the tuner playback mode. When the user presses the display screen with a specific finger in the audio operation mode, an operation command for operating the audio is input. When the user presses the display screen with a specific finger in the tuner operation mode, an operation command for the TV control unit 17 or the radio control unit 18 is input.

  As described above, in the input device 1 according to the present embodiment, the specific modes shown in Table 2, the movement of each finger in each mode, and the operation command corresponding to the movement of the finger are associated with each other in advance. Registered in the instruction correspondence table 34. By registering finger movements corresponding to frequently used operation commands in advance in this way, the user can omit the task of registering finger operations corresponding to sequential operation commands. Improved convenience. In addition, even if the finger operation corresponding to the operation command is registered in advance as described above, the registered finger movement is changed according to the user's preference and re-registered in the operation command correspondence table 34. Therefore, the operation of the finger corresponding to the operation command can be changed according to the user's preference.

  In the input device 1 according to the present embodiment, the user selects a mode according to the display screen of the operation selection mode. However, the user selects the currently selected mode and selects the mode, and the user's instruction. A finger operation on the display screen may be associated with the operation command correspondence table 34.

  FIG. 9 is a schematic diagram showing a hierarchical structure of modes. FIG. 10 is a diagram illustrating a display screen when processing for registering the operation of the finger on the display screen and the operation command in association with the operation command correspondence table 34 is performed. As an example, processing for selecting the playlist mode 60 and registering the operation command for selecting the playlist mode 60 and the operation of the finger on the display screen in the operation command correspondence table 34 will be described.

  In the present embodiment, as described above, modes representing specific operation processes are hierarchized. Below the audio mode 57 are an HDD-Audio mode 58 and a CD Player mode 59. Further, a playlist mode 60, an album mode 61, an artist mode 62, and the like are below the HDD-Audio mode 58. The playlist mode 60 is associated with the audio mode 57 and the HDD-Audio mode 58 in this order.

  10 (1) to 10 (3) are diagrams showing display screens when the playlist mode 60 is selected. On the display screen, a button 43 for transitioning to the operation registration mode is displayed in addition to an image for displaying the current mode. When the user presses the button 43 for transition to the operation registration mode, information indicating that the current mode is selected is input, and the transition to the operation registration mode is performed, and the above-described step b1 in FIG. 5 is performed. Transition.

  To select a play mode list, first, the HDD-Audio mode 58 is selected from a plurality of modes associated with the lower layer of the audio mode 57, and then the play list mode associated with the lower layer of the HDD-Audio mode 58 is selected. 60 is selected. When the playlist mode 60 is selected, a plurality of modes that are changed to the playlist mode 60 and associated with the lower layers of the playlist mode 60 and a button 43 for changing to the operation registration mode are displayed on the display screen. When the user presses the display area representing the button 43 for transitioning to the operation registration mode on this display screen, information indicating selection of the playlist mode 60 is input, and transition to the operation registration mode is performed. The process proceeds to step b1 in FIG. The processing for registering the operation command for selecting the playlist mode 60 in the operation command correspondence table 34 in correspondence with the movement of the finger is the same as the processing from step b1 to step b15 described above, and therefore a duplicate description is omitted. To do.

  Since the input device 1 includes the button 43 for transitioning to the operation registration mode, the user selects the current mode and transitions to the operation registration mode simply by pressing the button 43. Thus, it is possible to save the effort of selecting the mode corresponding to the operation command to be registered, and to register the finger operation and the operation command for selecting the mode in the operation command correspondence table 34 in correspondence with each other. Improves.

  In the input device 1 according to another embodiment of the present invention, not only the finger type but also the individual is determined based on the fingerprint image. Thus, by determining the individual based on the fingerprint image, the individual, the type of finger, and the trajectory information and the operation command are associated with each other and registered in the operation command correspondence table 34, and the command generation unit 12 stores the individual, finger An operation command may be generated based on the type and trajectory information. Thus, by determining the individual in addition to the finger type and the trajectory information, it becomes possible to register an operation command corresponding to the operation of the finger in the operation command correspondence table 34 for each person. That is, even if different people operate the same finger on the display screen, different operation commands can be input. In this way, an operation command can be set for one car navigation system 2 according to the user. Thereby, for example, when the car navigation system 2 is shared by a plurality of people, convenience for the user is improved.

  In the input device 1 according to still another embodiment of the present invention, when an individual is identified and a finger operation on the display screen of each person and an operation command are registered in correspondence with each other in the operation command correspondence table 34. Is configured so that the correspondence between the operation of the finger registered only by the person who has registered the operation command in the operation command correspondence table 34 and the operation command can be changed. Specifically, the command generation unit 12 determines whether or not a person has registered an operation command by determining a fingerprint image, and if the user has registered the operation command, the registered finger operation and the operation If the correspondence relationship with the command is changed and re-registration in the operation command correspondence table 34 is permitted, and it is determined that the person is not the person who registered the operation command, the change is not permitted. Accordingly, it is possible to prevent a finger operation for inputting an operation command from being changed by another person without the user's knowledge, and the convenience of the user is improved.

  The input device 1 according to still another embodiment of the present invention displays character information representing the mode currently displayed on the display screen on the display screen. Thus, by displaying the character information representing each mode on the display screen, the user can easily recognize the current mode. For example, even when the same display screen is displayed in different modes, the character information representing the mode is displayed, so that the current mode can be easily recognized. Furthermore, since the character information indicating the mode is displayed, when the mode is changed to another mode by the operation of the finger on the display screen, the changed mode can be easily grasped.

  The input device 1 according to still another embodiment of the present invention outputs sound information representing the mode currently displayed on the display screen from the speaker 7 as sound. Thus, by outputting the sound information representing each mode as a sound, the user can easily recognize the current mode. Furthermore, since the sound information indicating the mode is output as sound, when the mode is changed to another mode by a finger operation on the display screen, the changed mode can be easily grasped. In particular, even when a transition is made to another mode by operating a finger on the display screen without looking at the display screen, the transitioned mode can be grasped, so that convenience for the user is improved.

  Although the input device 1 according to the present embodiment is mounted on the car navigation system 2, the input device 1 is not limited to the car navigation system 2, and may be mounted on a device including an input device such as an audio device and an AV device. .
