Description

The present invention relates to an input device that performs an input operation by using a switch function or a drawing function of an operation screen of a device controlled by a PC or the like or a so-called media terminal, and the like on the operation screen without using a touch panel or a mouse. The switch function and drawing function are used to enable input operations.

In a device controlled by a conventional personal computer or the like, operating conditions and the like are input by operating a mouse and a keyboard while looking at an operation screen. In this case, in many cases, a switch for selecting a function is displayed on the operation screen, and the operator clicks a desired switch with the mouse to set the function and operating condition of the device to be controlled. In addition, the operating conditions of the apparatus using the operation screen may be input not only by the switch operation on the operation screen but also by displaying an area or a line segment on the operation screen using a drawing function.

Further, during operation of the apparatus, a switch on the operation screen may be operated as necessary to set or instruct operation of the apparatus.

Although the input method using the operation screen and the mouse has been described above, when the operation screen is a touch panel instead of the mouse, the same operation can be performed by touching the touch panel.

Japanese Patent No.4438351

Whether performing an input operation using an operation screen and a mouse, or an input operation using an operation screen that is a touch panel, the operator must be in the vicinity of this operation screen, and at least One hand needs to be used for the input operation, and there are disadvantages such as a reduction in work efficiency due to the input operation, such as a temporary interruption of the work of both hands.

Furthermore, in the case of a touch panel, there are some scenes where it is desirable to reduce the area of the switches displayed on the touch panel and arrange as many switches as possible. There is also a disadvantage that there is a limit. This is a particularly serious problem in a so-called media terminal having a small touch panel area.

As a method for improving these inconveniences, for example, in Japanese Patent No. 4443351, the speed and acceleration of the illuminant monitored by the camera are detected, and if these match a predetermined movement, the input corresponding to this movement is detected. By processing, remote control, freeing both hands, etc. are realized.

However, in this method, the remote input device is complicated and expensive, and when many types of input operations are to be performed, the operation of the light emitter is complicated, and it is necessary to store many operation patterns. There are also inconveniences that impair the operability such as increasing the possibility of malfunction.

Therefore, the present invention provides a remote input device having a simple and easy mechanism and excellent operability.

For devices that perform input operations using the switch function and drawing function of the operation screen, the light source that the operator holds is captured by the camera and displayed on the operation screen, allowing input using the switch function and drawing function on the operation screen. It can be used for operation.

Here, whether the illuminator is just moving, meaning a click action, or a drag action, etc., depends on the issue status of the illuminant (lighted or blinking, blinking cycle, The time ratio of blinking on / off, blinking pattern, brightness / darkness, wavelength, moving speed of light emitter, stop time of light emitter, etc.) can be identified.

Further, if this light emitter is attached to a finger sack or the like, the operator does not need to hold the light emitter and both hands can be made free.

By configuring as described above, it is possible to realize a remote operation or an input operation with both hands free with a simple remote input device and good operability. Furthermore, since many switches can be arranged on one page, it is possible to improve operability such as so-called media terminals having a small touch panel, such as omitting the number of page turning times.

(First embodiment)

The first embodiment will be described with reference to FIGS. 1 to 9, taking as an example the utilization to an apparatus such as a production facility.

FIG. 1 is an overall conceptual diagram of an embodiment according to the present invention, in which 1 is an operation screen, 2 is a camera, 3 is a processing unit, 4 is a light emitter using an LED as a light source, and 5 is an operator.

The operation screen 1 has a switch function and a drawing function, and displays only the light emitter 4 in the image captured by the camera 2 by the action of the processing unit 3. In order to separate the light-emitting body 4 and the background image from the images captured by the camera 2, it is preferable to identify differences between the light-emitting body 4 and the background brightness, light emission wavelength, and whether or not it is moving.

The operator 5 moves the light-emitting body 4 held in the hand within the field of view of the camera 2, operates the switch function and the drawing function of the operation screen 1 using means for distinguishing light emission (described later), and Enter operation instructions and operating conditions on operation screen 1. Although not shown, the operation screen 1 is connected to a device to be controlled, and the device operates according to the input content sent from the operation screen 1.

FIG. 2 is an explanatory diagram of the switch function and drawing function of the operation screen 1.

The switch function refers to the devices to be controlled by selecting the switches 1-1 arranged on the operation screen 1, for example, inputting a selected character and executing an operation such as a “start” switch. It is intended to implement the set function.

The drawing function is input using a line segment (created by connecting the line by specifying the start point and end point) as shown in 1-2 on the screen. You can enter the area you want to specify or enter a figure (not shown).

Naturally, a mechanism and a processing function for this are necessary, but the technology for this is well known in the art, and detailed description thereof is omitted here.

lighting blinking

In the above state, only the light emitter 4 is displayed on the operation screen 1 together with the switches, for example, whether the light emitter 4 is merely moving on a certain switch, or the switch. The processing unit 3 cannot understand the intention of the operator 5.

As a means for making this distinction, it is effective to utilize the difference in the light emission state of the light emitter 4.

In FIG. 2, 1-4 indicates that the light emitter 4 is in a blinking state, and 1-5 indicates that the light emitter 4 is in a lighting state. This is a method of executing an input intended by the operator 5. The operator 5 moves the light emitter 4 so that the light emitter 4 blinks on the switch 1-1 to be selected while keeping the light emitter 4 in the blinking state 1-4. When the light emitter 4 blinks on 1, the light switch 4 is switched from the blink state 1-4 to the lighting state 1-5 so that the desired switch 1-1 can be selected.

Although the switch function has been described as an example here, the drawing function can be similarly performed. In other words, for example, when you want to draw a line segment, you can enter the line segment by moving in the blinking state 1-4 until the start point and switching to the lighting state 1-5 from the start point to the end point of the line segment. Become.

period

In addition to the above method for distinguishing the light emission state, there is also a method for executing the input intended by the operator 5 by blinking the light emitter 4 and identifying the difference in the cycle by the processing unit 3. In FIG. 3, the cycle Ta of the light emission mode “a” is twice the cycle Tb of the light emission mode “b”, and this difference is discriminated by the processing unit 3 so that the consciousness of the operator 5 is distinguished. For example, the switch 1-1 to be selected can be selected by moving to the target position in the state of the light emission mode a and switching to the light emission mode b.

Duty

In addition to the above, the method of distinguishing the light emission state performs the input intended by the operator 5 by blinking the light emitter 4 and identifying the difference in the ratio (duty) between the lighting time and the light-off time. There is also a method. In FIG. 4, the duty Dc of the light emission mode c is different from 25% and the duty Dd of the light emission mode d is different from 75%. By distinguishing this difference by the processing unit 3, the consciousness of the operator 5 is distinguished. is there. For example, the switch 1-1 to be selected can be selected by moving to the target position in the state of the light emission mode c and switching to the light emission mode d.

Flash mode

In addition to the above, there is a method for executing the input intended by the operator 5 when the processing unit 3 identifies the difference in the blinking pattern and the blinking pattern. FIG. 5 shows an example of an 8-bit pattern. For example, “10101100 (light emission is“ short, short, long ”)” in the light emission mode “e”, and “11110100 (light emission is“ long × long ”in the light emission mode f). 2, short “)” is set as one cycle, and this is repeatedly emitted, and this difference is identified by the processing unit 3 to distinguish the consciousness of the operator 5. For example, the emission mode e In this state, the switch 1-1 is selected by moving to the target position and switching to the light emission mode f.

Here, since it is uncertain at which timing the operator 5 switches the light emission mode, when setting the light emission mode, it is easy to understand the start point and end point of one cycle, such as making the pattern easy to identify both. (In the example of FIG. 5, the end point is set to “100” for both the light emission mode e and the light emission mode f).

Luminance

In addition to the above method for distinguishing the light emission state, there is also a method for executing the input intended by the operator 5 when the processing unit 3 identifies the luminance difference of the light emitter 4. For example, the switch 1-1 to be selected can be selected by moving to a target position with the luminance of the light-emitting body 4 lowered (darkening) and increasing the luminance (brightening).

wavelength

In addition to the above method for distinguishing the light emission state, there is also a method for executing the input intended by the operator 5 when the processing unit 3 identifies the difference in the light emission wavelength of the light emitter 4. For example, the switch 1-1 to be selected can be selected by moving the light emitter 4 to a target position in a red state and switching to a white color. (The wavelength range is not limited to visible light, but may be widely used such as infrared light.)

speed

In addition to the above method for distinguishing the light emission state, there is also a method for executing the input intended by the operator 5 when the processing unit 3 identifies the difference in the moving speed of the light emitter 4. The case where the luminous body 4 is moving at a speed faster than the speed Vm that defines the moving state is defined as the moving state, and the case where the luminous body 4 is moving at a speed slower than the speed Vs that defines the stopped state. The operator 5 is set to the stop state, and the operator 5 moves the light-emitting body 4 at a speed faster than Vm at the target position and stops at the target position (actually there is a movement of hand shake, but Vs or less The switch 1-1 to be selected can be selected.

End point (stop time)

In addition to the above, the method of distinguishing the light emission state executes the input intended by the operator 5 when the processing unit 3 identifies the difference in time when the light emitter 4 is stopped on the switch of the operation screen 1. There is also a way to do it. That is, when the light-emitting body 4 has been stopped for a time that is a threshold set in advance on the switch of the operation screen 1, it is determined that the switch has been selected. The operator 5 ignores the start point position of the locus of the light emitter 4, moves only the end point position onto the target switch, and stops the switch for a predetermined time, thereby selecting the switch 1-1 to be selected. it can.

The threshold time may be set to the shortest time that does not cause a malfunction as compared with the normal moving speed. Further, since there is an influence of camera shake even at the stop position, in order to determine the stop state, it is preferable to provide an allowable range for setting the stop position range, speed, acceleration, and the like.

Trajectory

In addition to the above method for distinguishing the light emission state, there is also a method for executing the input intended by the operator 5 by the processing unit 3 identifying the locus of movement of the light emitter 4. With reference to FIG. 6, some examples of recognizing the locus of the light emitter 4 and selecting the “start” switch on the operation screen 1 are shown.

The first method is a method of recognizing the end point of the locus on which the light emitter 4 has moved. That is, the locus of the luminous body 4 starting from the arbitrary position X1 is projected on the operation screen 1, and the luminous body is reached when the locus is reached on the switch 1-1 (“Start” switch in FIG. 6) to be selected. Stop the light emission of 4 or stop the light to stop the locus of the luminous body 4, and select the switch ("start" switch) located at the end point (Y1) of this locus (1-6 ).

The second method is a method of selecting a switch that a trajectory traveled by the light emitter 4 crosses. In other words, the locus of the luminous body 4 starting from the arbitrary position X2 is displayed on the operation screen 1, and the arbitrary position (after the locus crosses on the switch 1-1 ("Start" switch in FIG. 6) to be selected) In Y2), the light emission of the light emitter 4 is stopped or the light is interrupted to stop the locus of the light emitter 4, and a switch (a “start” switch) crossed by this locus is selected (1-7) ).

The third method is a method of selecting a switch in which the locus of movement of the light emitter 4 is bent. In other words, the locus of the luminous body 4 starting from the arbitrary position X3 is projected on the operation screen 1, and a bending point (Z) is provided on the switch 1-1 (“Start” switch in FIG. 6) to be selected. At the position (Y3), the light emission of the light emitter 4 is stopped or the light is interrupted to stop the locus of the light emitter 4, and the switch at the bending point (Z) of this locus is selected (1 -8). Here, the bending point (Z) may be created by the hand movement of the operator 5, or a “bending point switch” for indicating a bending point provided in the light emitter 4 described later may be used. . Further, it is necessary to set an allowable range for the bending angle θ for determining the bending point Z and the length of the line segment referred to for calculating the bending angle θ depending on the case.

The fourth method is a method of selecting the switch at the position where the locus on which the light-emitting body 4 has moved draws a closed figure. In other words, the locus of the luminous body 4 starting from the arbitrary position X4 is projected on the operation screen 1, a closed figure is drawn on the switch 1-1 ("start" switch) to be selected, and the arbitrary position (Y4) is drawn. Stops the light emission of the light emitter 4 or shuts off the light to stop the locus of the light emitter 4, and selects a switch ("start" switch) at a position where a closed figure of this locus is drawn. (1-9). Here, the closed figure does not necessarily cross the original trajectory, but the operability is improved if it is set so as to be in a substantially closed state. Further, the shape of the closed figure may be a circle or a polygon, and a circle or a polygon may be identified and a different function may be set for each.

Composite

As described above, nine methods for operating the switch function and drawing function of the operation screen 1 by identifying the light emission state of the light emitter 4 and inputting driving instructions and driving conditions have been described. Of course, complicated settings can be made by combining them. For example, the only distinction between lighting and blinking shown in claim 2 is the click and drag values when applied to the PC mouse, but if the brightness difference shown in claim 6 is added to this, for example, page up / down is added. A 4-valued operation can be performed, and if a difference in emission wavelength shown in claim 7 is added, an 8-valued distinction can be made.

In addition, when drawing a line segment on the operation screen 1, there are a method of displaying the locus of the light emitter 4 and a method of inputting a start point and an end point of the line segment as described above. It may be determined according to the situation used for the operation, or the operator 5 may select it each time (specific description is omitted).

Luminous body

An outline of the luminous body 4 will be described with reference to FIG.

4-1 is a main body, 4-2 is a light source such as an LED, 4-3 is a power source, 4-4 is a circuit board, 4-5 is a power switch, and 4-6 is a light emission mode changeover switch. In order to operate this, the light emission mode selector switch 4-6 is set to the desired light emission mode, the circuit is closed by the power switch 4-5, and the light source 4-2 is caused to emit light.

Here, the light source 4-2, the power switch 4-5, and the light emission mode change-over switch 4-6 may be configured in accordance with the scene to be used. For example, the power switch 4-5 is a toggle switch that is convenient for maintaining the light emission when it is desired to identify by switching the light emission mode. A button switch should be used. When it is desired to make full use of many light emission modes, the power switch 4-5 may be a rotary switch or a plurality of toggle switches, and the selector switch 4-6 may be a switch that can be easily switched. FIG. 7 shows one light source 4-2. For example, in the case of claim 7, it is easy to realize by arranging a plurality of LEDs corresponding to the wavelength.

FIG. 8 shows another example of the light emitter 6 different from that in FIG. 7. The difference from the light emitter 4 in FIG. 7 is whether or not the light emitting section is independent. A light source 6-2 separated from the main body 6-1 is disposed on the finger sack 6-4 and attached to the finger of the operator 5, and the main body 6-1 is placed in the chest pocket of the operator 5, for example. The luminous body 6 is connected by the cable line 6-3. With this configuration, the operator 5 does not have to hold the main body 6-1 in his / her hand, and can use his / her hands for work he / she wants to perform, such as holding parts or tools which work on both hands.

Although the finger sack 6-4 has been described as an example in FIG. 8, this may be a ring or the light source 6-2 may be fixed with a double-sided tape or the like (not shown).

Multiple light emitters

Although the case where there is one light emitter 4 has been described above, the number of light emitters 4 is not limited to one, and more complex input operations can be performed using a plurality of light emitters 4 each having a different light emission mode. It is.

Automatic screen switching

Furthermore, by automatically switching the display content of the operation screen 1 for each light emission mode of the light emitter 4, the trouble of switching between the condition input screen and the operation screen can be saved, If the light emitters 4 having different light emission modes are used, a plurality of operators 5 (a plurality of the light emitters 4) can be used in one set of the operation screen 1, the camera 2, and the processing unit 3. There are also benefits.

Area pre-setting

In addition, an effective area (7 in FIG. 9) that can be operated only when the luminous body 4 is projected in the area is set in advance in the operation screen 1 so that the operator 5 can set an easy-to-operate space range, prevent the influence of ambient light, and can use a plurality of the light-emitting bodies 4 in the same light emission mode simultaneously.

Furthermore, if an effective area is set for each light emission mode, it is only necessary to identify the light emission mode assigned to each effective area, so the burden on the processing unit 3 when a plurality of the light emitters 4 are used can be reduced. .

In setting the effective area, it may be set so that only the effective area set in the operation screen 1 functions as described above, and the area of the set effective area is expanded to the entire area of the operation screen 1. You may set as you do.

Isolation environment

In addition, the light emitter 4 is positioned almost in front of the camera 2 and the light emission of the light emitter 4 has been described on the assumption that it directly enters the camera 2. However, the light emitter 4 is reflected using a reflecting mirror or an optical fiber. The body 4 may be arranged at a position outside the field of view of the camera 2, or the light emitted from the light emitter 4 may enter the camera 2 through a transparent member such as a window glass in an isolated room.

As described above, using the first embodiment, utilizing the switch function and drawing function of the current touch panel, etc., freeing both hands at the time of remote operation and input operation, and reducing the area of the switch on the operation screen, a simple method and The basis of the present invention that it can be realized with good operability has been described.

Mobile phone

(Second embodiment)

A second embodiment will be described with reference to FIG.

In traditional media terminals, to select the switch you want to select on the display screen, you generally touch the switch you want to select with your finger (touch panel). Since an area that is not touched and an interval between switches are necessary, there is a disadvantage that the number of switches that can be arranged on the display screen is limited.

FIG. 10 is a conceptual diagram of a so-called smartphone 8 as a specific example of a media terminal, in which 8-1 is a touch panel which is a display screen, 8-2 is a camera, and 8-3 is provided on the display screen 8-1. A switch 4 is a light emitter held by an operator 5 (not shown).

The smartphone 8 is configured to display only the light emitter 4 in the image captured by the camera 8-2 on the display screen 8-3, and has a function of distinguishing the above-described light emission. The method in which the operator 5 moves the light emitter 4 within the field of view of the camera 2 and selects the desired switch 8-3 is the same as in the first embodiment.

Here, even if the light emitter 4 is moved by the same distance, the light emitter 4 is displayed on the display screen 8-2 depending on whether the light emitter 4 is moved closer to the camera 8-2 or farther away. Therefore, the operator 5 operates the light emitter 4 at a distance suitable for the scene, so that the switch 8-3 on the display screen 8-1 is operated. Even if the switch is so small that it cannot be selected with a finger, the input operation can be performed comfortably.

In addition, the smartphone 8 has an input method such as screen enlargement by touching the touch panel with the thumb and forefinger, but in order to realize this by means using the light emitter of the present invention, a finger sack 6-4 as shown in FIG. 8 is used. This can be realized by using two sets of the light emitters 6 provided with the light source 6-2 separated from the main body 6-1.

i-Pod

In the above description, a smartphone has been taken as an example. However, it is effective for operation screens such as game consoles, electronic books, and eyepads (registered trademark of Apple Inc.) that are composed of touch panels, and scrolls used with these devices. It is also effective for a device that performs input using an operation screen such as a function (moving a screen by moving a finger touching a touch panel in an arbitrary direction).

The input method using the illuminant that is the gist of the present invention has been described above. However, if the switch of the controlled device itself or the keyboard or mouse of the attached personal computer can be used together depending on the situation, the input work will be more efficient. It becomes easy to do.

Projector

(Third embodiment)

Furthermore, if the operation screen is a personal computer, the technology for projecting light from the light emitter onto the operation screen can be used as it is as a pointer in the projector.

FIG. 11 is a conceptual diagram of the entire third embodiment according to the present invention, 2 is a camera, 3 is a processing unit, 4 is a light emitter using an LED as a light source, 5 is an operator who is a presenter, and 9 is an operation screen. A personal computer, 10 is a projector main body, 11 is a screen, and 1-10 is the luminous body 4 projected on the personal computer 9. (For convenience, the screen 11 and the personal computer 9 are drawn in the same direction in FIG. 11, but in reality, the screen 11 and the operator 5 are on the audience side, and the camera 2 and the personal computer 9 are on the operator. (Looks on the 5th side (the direction toward the audience))

The personal computer 9 is processed by the processing unit 3 so as to display only the light emitter 4 in the image taken by the camera 2 together with the presentation material, and the light emitter 4 is displayed, and the screen of the personal computer 9 is displayed. The projector body 10 displays the image on the screen 11 in an enlarged manner.

With this configuration, the light emitter 4 can be used as a pointer that points to the presentation material on the screen 11. That is, the operator 5 who is a presenter moves the light-emitting body 4 held in the hand within the field of view of the camera 2 and switches the function of the pointer by using the means for distinguishing the light emission described above. Presentations can be made using functions (to be described later) that could not be realized with a laser pointer.

Details such as the means for distinguishing light emission and the means for separating the light-emitting body 4 and the background image from among the images taken by the camera 2 are as described in the first embodiment.

In order to separate the light-emitting body 4 and the background image from the images captured by the camera 2, it is preferable to identify differences between the light-emitting body 4 and the background brightness, light emission wavelength, and whether or not it is moving.

In conventional presentations, the laser pointer is used alone and simply points to the point. If the projector (laser pointer) of the present invention for interlocking the luminous body 4 with the personal computer 9 is used, a pointer mark is displayed on the personal computer 9 and this screen is projected by the projector main body 10, so that it is bright and sized. The shape and color can be freely selected, and a pointer that is easy to see even in large venues can be realized. A line segment or area can be displayed by leaving the locus of the luminous body 4. By providing the switch on the operation screen 1 described above on the screen of the personal computer 9, the personal computer 9 can be directly operated by the light emitter 4 such as page turning. The shaking of the hand with the traditional pointer should not be magnified on the screen, making it easier to see. Since the position of the pointer can be confirmed on the screen of the personal computer 9, the presenter can move away from the side of the personal computer (presenter's desk) even when moving the pointer, and has always been oriented toward the audience. There are no merits.

Surveillance camera

(Fourth embodiment)

In an automatic monitoring camera that automatically monitors a monitoring area based on an image captured by the camera, even a person who does not need to issue a warning (such as a person who is not monitored), such as a manager of the facility, enters the monitoring area. There is a problem in convenience that an alarm is issued.

Therefore, by using the present invention, it is possible to prevent an object that moves together with the light emitter from issuing an alarm even if it enters the monitoring area. In other words, if the operator 5 who is a non-monitoring person enters the monitoring area while pointing the light emitter 4 toward the camera 2 which is an automatic monitoring camera, the processing unit 3 determines that it is not an intruder. Just keep it.

Here, in addition to the function of reading the signal from the light emitter 4 of the present invention, the processing unit 3 incorporates an automatic monitoring function and a function of identifying an object moving together with the light emitter 4. However, since these are known techniques in the technical field, a detailed description thereof is omitted here.

Thereby, the person to be monitored can be automatically identified, and the convenience of the automatic monitoring camera can be improved.

Further, if the instruction content is assigned for each light emission mode of the light emitter 4, the operator 5 can remotely control the automatic monitoring camera while at the site to be monitored (within the field of view of the camera 2, that is, the monitoring area and its surroundings). It is also possible to perform input operations. For example, if the duty is 25%, you are a non-monitoring person, so even if you enter the monitoring area, an alarm will not sound, 50% will stop automatic monitoring, 75% will resume automatic monitoring, etc. Remote input operation of the automatic surveillance camera becomes possible while on the spot.

Here, in addition to the method of using the difference in the light emission mode described in the first embodiment, the method of distinguishing the light emission state is a figure drawn by the locus of the light emitter 4 (vertical line / horizontal line, circle, rectangle, triangle, There is also a method using wave patterns).
