FIG. 10 is an illustrative view showing another example of an object displayed on the display shown in FIG.

Referring to FIG. 1, a mobile phone 10 of this embodiment is a kind of mobile terminal, and includes a processor 24 called a CPU or a computer. Further, the wireless communication circuit 14, A / D 16, D / A 20, key input device 26, display driver 28, flash memory 32, RAM 34, and touch panel control circuit 36 are connected to the processor 24. An antenna 12 is connected to the wireless communication circuit 14, a microphone 18 is connected to the A / D 16, and a speaker 22 is connected to the D / A 20 via an amplifier (not shown). A display 30 is connected to the display driver 28. A touch panel 38 is connected to the touch panel control circuit 36.

  The processor 24 is a control IC and controls the entire mobile phone 10. The RAM 34 is used as a work area (including a drawing area) or a buffer area of the processor 24. Content data such as characters, images, sounds, sounds and videos of the mobile phone 10 is recorded in the flash memory 32.

  The A / D 16 converts an analog audio signal for audio or sound input through the microphone 18 connected to the A / D 16 into a digital audio signal. The D / A 20 converts (decodes) the digital audio signal into an analog audio signal and applies the analog audio signal to the speaker 22 via the amplifier. Therefore, sound or sound corresponding to the analog sound signal is output from the speaker 22.

  The key input device 26 includes a call key 26a, a menu key 26b, and an end call key 26c shown in FIG. In addition, information (key data) on keys operated by the user is input to the processor 24. When each key included in the key input device 26 is operated, a click sound is generated. The user can obtain an operational feeling for the key operation by listening to the click sound.

The display driver 28 controls display on the display 30 connected to the display driver 28 under the instruction of the processor 24. The display driver 28 includes a VRAM that temporarily stores image data to be displayed. Then, the processor 24 stores the image data to be displayed on the display 30 in this VRAM.

  The touch panel 38 is a capacitive type that detects a change in capacitance between electrodes caused by an object (contact member) such as a finger approaching the surface. For example, one or more fingers touch the touch panel 38. Detect that. The touch panel 38 is a pointing device for instructing an arbitrary position within the screen of the display 30. For example, when the touch panel 38 is operated by pressing, stroking (rubbing), or touching the surface with a finger, the touch panel 38 detects the operation. Then, when the touch panel 38 touches the touch panel 38, the touch panel control circuit 36 that functions as a contact detection unit specifies the position of the finger and outputs coordinate data indicating the operated position to the processor 24. That is, the user can input an operation direction, a figure, or the like to the mobile phone 10 by pressing, stroking, or touching the surface of the touch panel 38 with a finger.

  Here, an operation in which the user touches the surface of the touch panel 38 with a finger is referred to as “touch”. On the other hand, the operation of releasing the finger from the touch panel 38 is referred to as “release the touch” or “release”. The coordinates indicated by the touch are referred to as “touch point (first position)”, and the coordinates indicated by the release are referred to as “release point (second position)”. Further, the operation of stroking the surface of the touch panel 38 is referred to as “slide”, “slide touch operation”, or “operation of moving by bringing a contact member into contact”. Further, an operation in which the user touches the surface of the touch panel 38 and subsequently releases it is referred to as “touch and release”. The operations performed on the touch panel 38 such as touch, release, slide, and touch-and-release are collectively referred to as “touch operation (contact)”.

  Note that the touch operation is not limited to a finger, and may be performed by other objects such as a touch pen with a conductor attached to the tip. Further, as a detection method of the touch panel 38, a surface-type capacitance method may be employed, or a resistance film method, an ultrasonic method, an infrared method, an electromagnetic induction method, or the like may be used.

  The wireless communication circuit 14 is a circuit for performing wireless communication in the CDMA system. For example, when the user instructs a telephone call using the key input device 26, the wireless communication circuit 14 executes a telephone call process under the instruction of the processor 24 and outputs a telephone call signal through the antenna 12. The telephone call signal is transmitted to the other party's telephone through a base station and a communication network (not shown). Then, when an incoming call process is performed at the other party's telephone, a communicable state is established, and the processor 24 executes a call process.

  The normal call processing will be described in detail. The modulated audio signal transmitted from the other party's telephone is received by the antenna 12. The received modulated audio signal is demodulated and decoded by the wireless communication circuit 14. The received voice signal obtained by these processes is converted to an analog voice signal by the D / A 20 and then output from the speaker 22. On the other hand, the transmission voice signal captured through the microphone 18 is converted into a digital voice signal by the A / D 16 and then given to the processor 24. The transmission signal converted into the digital audio signal is subjected to encoding processing and modulation processing by the wireless communication circuit 14 under the instruction of the processor 24, and is output via the antenna 12. Therefore, the modulated voice signal is transmitted to the other party's telephone through the base station and the communication network.

When a call signal from the other party's telephone is received by the antenna 12, the wireless communication circuit 14 notifies the processor 24 of an incoming call (sometimes called an incoming call). In response to this, the processor 24 controls the display driver 28 to display the caller information (phone number) described in the incoming call notification on the display 30. At the same time, the processor 2
4 outputs a ringtone (sometimes called a ringing melody or a ringing voice) from a speaker (not shown). Further, the processor 24 vibrates the mobile phone 10 or emits an LED (not shown) to notify the user of an incoming call.

  When the user performs a response operation using the call key 26a, the wireless communication circuit 14 executes the incoming call process under the instruction of the processor 24, and a communicable state is established. Perform normal call processing.

  In addition, when a call end operation is performed by the call end key 26c after the transition to the call ready state, the processor 24 controls the wireless communication circuit 14 to transmit a call end signal to the call partner. After transmitting the call end signal, the processor 24 ends the call process. The processor 24 also ends the call process when a call end signal is received from the other party first. Furthermore, the processor 24 also ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  FIG. 2A is an external view showing the external appearance of the front surface of the mobile phone 10, and FIG. 2B is an external view showing the external appearance of the back surface of the mobile phone 10. Referring to FIG. 2A, the mobile phone 10 has a straight shape and has a flat rectangular casing C. The microphone 18 (not shown) is built in the housing C, and the opening OP2 leading to the built-in microphone 18 is provided on one surface of the housing C in the length direction. Similarly, the speaker 22 (not shown) is built in the housing C, and the opening OP1 leading to the built-in speaker 22 is provided on the other surface in the longitudinal direction of the housing C. The display 30 is attached so that the monitor screen can be seen from the front side of the housing C. The display 30 is provided with a touch panel 38. The key input device 26 includes a call key 26a, a menu key 26b, and an end call key 26c. These keys are provided on the surface of the casing C.

  For example, the user inputs a telephone number by performing a touch operation on a dial key displayed on the display 30, and performs a telephone call operation using the call key 26a. When the call ends, the user performs a call end operation using the end call key 26c. In addition, the user selects and confirms the menu by performing a touch operation on the soft keys and the menu displayed on the display 30. Then, the user turns on / off the power of the mobile phone 10 by pressing and holding the end call key 26c.

  2A and 2B, the antenna 12, the wireless communication circuit 14, the A / D 16, the D / A 20, the processor 24, the display driver 28, the flash memory 32, the RAM 34, and the touch panel control circuit 36 are the case C. Are not shown in FIGS. 2A and 2B.

  Here, the mobile phone 10 has a lock function that restricts functions available on the mobile phone 10 such as a telephone function or prevents the touch panel control circuit 36 from accepting a touch. For example, when the end call key 26c is operated, the power of the display 30 and the touch panel 38 is turned off and the lock state is set, and the touch operation for executing the telephone function or the like is invalidated. Further, when the power of the display 30 is turned on while the lock state is set, the touch panel 38 is also turned on at the same time, so that a touch operation is detected. And if the touch operation mentioned later is performed, a locked state will be cancelled | released.

First, referring to FIG. 3A, when the menu key 26b is operated in a state where the lock state is set, the display 30 is turned on and a lock screen is displayed. The display area of the display 30 includes a status display area 60 and a function display area 62. In the status display area 60, an icon (sometimes referred to as a pictograph) indicating the radio wave reception status by the antenna 12, an icon indicating the remaining battery capacity of the secondary battery, and the current date and time are displayed. The current time displayed in the status display area 60 is based on time information output by an RTC (Real Time Clock) (not shown).

  Next, a long object To is displayed on the lock screen displayed in the function display area 62. This object To is indicated by an image that looks like a tape, and is defined by a predetermined first function and second function. An upper boundary line La and a lower boundary line Lb indicating the boundary between the object To and the background correspond to the first function and the second function. Then, when the user touches the touch panel 38 and slides so that the locus intersects the object To, the locked state can be released. Hereinafter, when the upper boundary line La and the lower boundary line Lb are not particularly distinguished, they are referred to as “boundary lines L”, and when the first function and the second function are not particularly distinguished, they are referred to as “functions”. To.

  Referring to FIG. 3B, when the user is sliding, if the current touch position comes on the upper boundary line La, the object To enters the first display state with a break. Be changed. That is, when the user's finger comes into contact with the object To, the object To is displayed as if it was cut by sliding. Thereby, the user can know that the touch operation for releasing the locked state is effective.

  Next, referring to FIG. 3C, when the current touch position is on the lower boundary line Lb by further sliding, the object To becomes the first object Toa and the second object Tob. The display state is changed to the divided second display state. That is, when the slide by the user finishes intersecting with the object To, the object To is displayed as if it was broken by the slide. The display of the object To divided into two is erased after a predetermined time (for example, 1 second). Then, the display of the object To is erased and the locked state is released, and a standby image indicating the standby state is displayed on the display 30 as shown in FIG. Therefore, the user can know that the operation for releasing the locked state has been completed normally by looking at the object To in the second display state.

  In the present embodiment, the finger contact with the upper boundary line La and the lower boundary line Lb is determined by substituting coordinates indicating the current touch position into a function corresponding to each boundary line. For example, if the first function is established by the coordinates indicating the current touch position, it is determined that the user's finger has contacted the upper boundary line La. Further, if the second function is established by the coordinates indicating the current touch position, it is determined that the user's finger is in contact with the lower boundary line Lb. In this embodiment, the lock state is released if both the first function and the second function are established by the coordinates of the touch position that is changed by the slide.

  As described above, in this embodiment, it is possible to prevent the lock state from being released due to an erroneous operation by using two functions to release the lock state. Further, since the object To is defined by a predetermined function, the intersection between the object To and the slide can be easily determined based on the predetermined function.

  Note that when released in a state where only the first function is established, the object To returns from the first display state shown in FIG. 3B to the display state shown in FIG.

  If the touch point is included in the display range of the object To, the touch is invalidated. That is, when the slide starts from the inside of the object To, even if the finger touches each boundary line, the display state of the object To is not changed at all, and the locked state is not released. When such an operation is performed, the user may be notified that the operation is incorrect.

  Further, the position where the object To is displayed is not limited to the position shown in FIG. 3A as long as the intersecting slide can be performed.

  Further, the position of the break shown in FIG. 3B is displayed corresponding to the touch position. In other words, the center of the cut is displayed in accordance with the touched position. However, in another embodiment, the break may be displayed regardless of the position where the touch position is touched. Further, the break of the object To may be changed according to the touch position. For example, if the slide distance is short, the break is displayed smaller, and as the slide distance increases, the break is displayed larger.

  In another embodiment, the first function may correspond to the lower boundary line Lb, and the second function may correspond to the upper boundary line La. In the above embodiment, the locked state is released by the downward slide, but the locked state is released by the upward slide. In this case, when it comes to exist on the lower boundary line Lb, the cut shown in FIG. 3 (B) is displayed upside down. However, in other embodiments, an erroneous operation may be prevented by defining the order of functions to be established. For example, in another embodiment, the locked state can be prevented from being released even when the slide is performed in a downward direction and the locus intersects with the object To.

  In the present embodiment, the touch is disabled by turning off the power of the touch panel control circuit 36 and the touch panel 38. Therefore, the power consumption of the mobile phone 10 is further suppressed. However, in another embodiment, the touch may be invalidated by executing processing of ignoring the input touch coordinates by the processor 24 without turning off the touch panel control circuit 36 and the touch panel 38. .

  FIG. 4 is a diagram showing a memory map 300 of the RAM 34. The memory map 300 of the RAM 34 includes a program storage area 302 and a data storage area 304. Further, a part of the program and data are read from the flash memory 32 all at once or partially and sequentially as necessary, stored in the RAM 34, and then processed by the processor 24.

  The program storage area 302 stores a program for operating the mobile phone 10. For example, a program for operating the mobile phone 10 includes a lock state setting program 310 and a lock state release program 312. The lock state setting program 310 is a program for setting a lock state in the mobile phone 10. The lock state release program 312 is a program for releasing the lock state set in the mobile phone 10.

  Although illustration is omitted, the program for operating the mobile phone 10 includes a program for notifying the incoming call state and a program for establishing the call state.

  In the data storage area 304, a touch buffer 330, an intersection calculation buffer 332, and the like are provided, and touch coordinate map data 334, object data 336, boundary function data 338, and the like are stored. The data storage area 304 is also provided with a lock flag 340, a no-operation counter 342, and the like.

The touch buffer 330 temporarily stores coordinates indicating the touch point output from the touch panel control circuit 36, coordinates indicating the release point, coordinates indicating the current touch position, and a plurality of coordinates indicating the locus of the slide. The intersection calculation buffer 332 is a buffer used when an operation for substituting the coordinates of the current touch position indicated by the slide into the first function and the second function is executed.

  The touch coordinate map data 334 is data for associating the touch coordinates in the touch operation with the display coordinates of the display 30. That is, the processor 24 associates the result of the touch operation performed on the touch panel 38 with the display 30 based on the touch coordinate map data 334. The object data 336 is image data of the object To that is displayed on the display 30. The boundary function data 338 is data indicating a first function corresponding to the upper boundary line La and a second function corresponding to the lower boundary line Lb. Note that the boundary function data 338 varies depending on the shape and position of the object displayed on the display 30.

  The lock flag 340 is a flag for determining whether or not a lock state is set. For example, the lock flag 340 is composed of a 1-bit register. When the lock flag 340 is turned on (established), a data value “1” is set in the register. On the other hand, when the lock flag 340 is turned off (not established), a data value “0” is set in the register.

  The no-operation counter 342 is a counter for measuring a certain time (for example, 60 seconds), and starts counting when initialized. The no-operation counter 342 is also called an no-operation timer. When the no-operation timer is executed, the no-operation counter 342 is initialized and starts counting. The no-operation timer is initialized every time a key operation or a touch operation is performed.

Although illustration is omitted, the data storage area 304 stores a buffer for temporarily storing data output by the RTC, image data for displaying a GUI, and the like, and the operation of the mobile phone 10. Necessary counters and flags are also provided.

The processor 24 performs a lock state setting process shown in FIG. 5 and a lock state release process shown in FIG. 6 under the control of a Linux (registered trademark) -based OS such as Android (registered trademark) and REX, and other OSs. Including multiple tasks in parallel.

  FIG. 5 is a flowchart of the lock state setting process. For example, when the power of the mobile phone 10 is turned on, the processor 24 determines whether or not an operation is performed in step S1. That is, the processor 24 determines whether or not the no-operation timer has expired because no touch operation or key operation has been performed for a certain period of time. If “YES” in the step S1, for example, if the touch operation and the key operation are not performed for 60 seconds, the processor 24 proceeds to a step S5. On the other hand, if “NO” in the step S1, that is, if the no-operation timer has not expired, the processor 24 determines whether or not an operation for setting the lock state is performed in a step S3. For example, the processor 24 determines whether or not the end call key 26c has been operated. If “NO” in the step S3, that is, if the operation for setting the lock state is not performed, the processor 24 returns to the step S1.

  On the other hand, if “YES” in the step S3, that is, if an operation for setting the lock state is performed, the processor 24 turns off the power of the display 30 in a step S5. That is, the processor 24 issues a command to turn off the power of the display 30 to the power supply circuit. Subsequently, the processor 24 sets a lock state in step S7, and ends the lock state setting process. That is, the processor 24 sets the lock flag 340 to OFF in step S7.

  In another embodiment, the display 30 may be turned off after the lock state is set. In this case, in the lock state setting process of FIG. 5, the order of step S5 and step S7 is switched. That is, in another embodiment, the process of step S5 is executed after the process of step S7 is executed.

  FIG. 6 is a flowchart of the lock state release process. For example, when the menu key 26b is operated while the lock state is set, the processor 24 displays a lock screen in step S21. That is, the processor 24 displays the lock screen shown in FIG. 3A on the display 30 after issuing a command to turn on the power of the display 30. The processor 24 that executes the process of step S21 functions as a display unit.

  Subsequently, the processor 24 determines whether or not it is touched in step S23. That is, it is determined whether or not a touch is detected by the touch panel control circuit 36. If “NO” in the step S23, that is, if a touch is not detected by the touch panel control circuit 36, the processor 24 repeatedly executes the process of the step S23.

  If “YES” in the step S23, that is, if a touch is detected by the touch panel control circuit 36, the processor 24 determines whether or not the slide is performed in a step S25. For example, the processor 24 reads the coordinates of the touch position detected last time from the touch buffer 330 and the coordinates of the touch position detected this time, and determines whether the two coordinates are different. If “NO” in the step S25, that is, if it is not slid, the processor 24 proceeds to a step S29. On the other hand, if “YES” in the step S25, that is, if the slide is performed, the processor 24 determines whether or not it has started to intersect with the slide object To in a step S27. For example, the processor 24 reads the coordinates indicating the current touch position from the touch buffer 330, reads the first function and the second function from the boundary function data 338, and determines whether the first function or the second function is established based on the read coordinates. Judge whether or not. Each time the process of step S27 is executed, the calculation result is stored in the intersection calculation buffer 332.

  If “NO” in the step S27, for example, if the current touch position is a position away from the object To and the first function is not established by the coordinates indicating the touch position, the processor 24 has been released in the step S29. Judge whether or not. That is, it is determined whether or not the finger is released from the touch panel 38. If “NO” in the step S29, that is, if the touch panel 38 is still touched, the processor 24 returns to the step S25. On the other hand, if “YES” in the step S29, that is, if the finger is released from the touch panel 38, the processor 24 returns to the step S23.

  If “YES” in the step S27, that is, if the current touch position exists on the upper boundary line La or the lower boundary line Lb of the object To, the processor 24 has started to cross from the top in the step S31. Judge whether or not. That is, the processor 24 determines whether or not the first function corresponding to the upper boundary line La is established based on the coordinates indicating the current touch position. If “YES” in the step S31, for example, as shown in FIG. 3B, if the slide starts to cross from the top of the object To, the processor 24 tears the display of the object To from the top in step S33. Change to the display state (first display state), and the process proceeds to step S37. For example, as shown in FIG. 3B, the processor 24 displays an object To having a cut from above on the display 30.

On the other hand, if “NO” in the step S31, that is, if the second function corresponding to the lower boundary line Lb is established by the coordinates indicating the current touch position, the processor 24 displays the object To in a step S35. Then, the state is changed to the state of being torn from below (first display state), and the process proceeds to step S37. That is, the processor 24 displays on the display 30 the object To that has been cut from below. The processor 24 that executes the process of step S33 or step S35 functions as a first changing unit.

  Subsequently, in step S37, the processor 24 determines whether or not the slide has intersected with the object To. For example, if the first function corresponding to the upper boundary line La has already been established, the processor 24 determines whether or not the second function corresponding to the lower boundary line Lb is established based on the coordinates indicating the current touch position. . The processor 24 that executes the processes of steps S27 and S37 functions as a determination unit. In particular, the processor 24 that executes the process of step S27 functions as a first determination unit, and the processor 24 that executes the process of step S37 functions as a second determination unit.

  If “NO” in the step S37, for example, if the second function corresponding to the lower boundary line Lb is not established by the coordinates indicating the touch position, the processor 24 determines whether or not the second function is released in a step S39. That is, the processor 24 determines whether or not the finger is released from the touch panel 38 as in step S29. If “NO” in the step S39, that is, if the current touch position is included in the display coordinates of the object To, the processor 24 returns to the step S37. On the other hand, if “YES” in the step 39, that is, if the slide is interrupted before the slide trajectory has completely crossed the object To, the processor 24 returns to the step S21. For example, if the object To is in the first display state shown in FIG. 3B, the object To is returned to the state shown in FIG.

  On the other hand, if “YES” in the step S37, for example, if the second function corresponding to the lower boundary line Lb is established by the current touch position, the processor 24 has completely broken the display of the object To in the step S41. Change to state (second display state). That is, the processor 24 displays the object Toa and the object Tob divided into two on the display 30 as shown in FIG. The processor 24 that executes the process of step S41 functions as a second changing unit.

  Subsequently, in step S43, the processor 24 releases the lock state and ends the lock state release processing. That is, the processor 24 turns off the lock flag 340. The processor 24 that executes the process of step S43 functions as a release unit.

  As can be seen from the above description, the mobile phone 10 has the touch panel 36 that detects a touch operation. Further, the mobile phone 10 can be set in a locked state that restricts a predetermined function provided in the mobile phone from being executed by a touch operation. When the lock state is set, a touch operation related to the release of the lock state is detected. For example, when a key input operation is performed in a state where the lock state is set, a long object To that looks like a tape is displayed on the display 30. When the user performs a slide that intersects the object To, the processor 24 releases the locked state.

  As described above, since the touch operation for releasing the locked state is prompted by the display of the object To, the method for releasing the locked state can be transmitted regardless of the language used by the user.

In the present embodiment, the boundary line L of the object To is represented by a straight line. However, in another embodiment, the boundary line L may be a curve or may include a vertex. That is, the function corresponding to each boundary line L is not limited to a linear function, and various functions may be supported. For example, as shown in FIG. 7, when the boundary line L is a curve, each boundary line L corresponds to a cubic function or a trigonometric function such as sine and cosine. Further, as shown in FIG. 8, when the boundary line L is a triangular wave having a plurality of vertices, a triangular function corresponds to each boundary line L.

  Further, the two boundary lines L constituting the object To do not necessarily have to be parallel. For example, two functions having intersections may correspond to two boundary lines L, such as an upper boundary line La and a lower boundary line Lb shown in FIG.

  In another embodiment, the object To may be indicated by a figure such as a triangle or a circle instead of a strip shape.

  In another embodiment, a plurality of objects To may be displayed. When a plurality of objects To are displayed, when the objects To are slid so as to intersect with all the objects To, the locked state is released. For example, referring to FIGS. 10A to 10E, an object To1 and an object To2 are displayed on the display 30. FIG. Further, the upper boundary line La and the lower boundary line Lb of each object To are defined by a first function and a second function.

  Next, as shown in FIG. 10B, when the position of the slide comes into contact with the upper boundary line La1, a cut is made in the object To1. When the slide is further continued and the current position touches the lower boundary line Lb1, the object To is divided into an object To1a and an object To1b as shown in FIG.

  Here, when the user continues sliding without releasing the finger, as shown in FIG. 10D, the object To2 is cut, and as shown in FIG. 10E, the object To2 becomes the object To2a. It is divided into an object To2b. When the two objects To are displayed torn, the locked state is released.

  As described above, when two objects To are displayed at the same time, the locked state is not released unless a slide operation intersecting with all the objects To is performed.

  However, in the state of FIG. 10C, the display of the object To divided into two may be deleted in order to notify that the user's operation is being performed correctly. Further, if the slide does not move or is released at all while the display of FIG. 10C is displayed, the possibility of an erroneous operation is high, so the display of the two objects To is shown in FIG. It is returned to the state.

  In another embodiment, in order to clarify that the lock state is set, the object To may be displayed on the lock screen so as to overlap the standby screen shown in FIG. . In this case, even a user who uses the mobile phone 10 for the first time can easily slide the object To regardless of the language used by the user.

  In another embodiment, icons indicating blades such as scissors and knives may be displayed in accordance with the position touched by the user to prompt the object To to slide.

The communication system of the mobile phone 10 is a CDMA system, but an LTE (Long Term Evolution) system, a W-CDMA system, a GSM system, a TDMA system, an FDMA system, a PHS system, or the like may be adopted. Furthermore, although an LCD monitor is used for the display 30, other display devices such as an organic EL panel may be used.

The lock state setting program 310 and the lock state control program 312 may be stored in the HDD of the data distribution server and distributed to the mobile phone 10 via the network. In addition, the storage medium may be sold or distributed in a state where these programs are stored in an optical disk such as a CD, DVD, or BD (Blu-ray Disc), a USB memory, or a memory card. Then, when the lock state setting program 310 and the lock state control program 312 downloaded through the above-described server or storage medium are installed in a mobile phone having the same configuration as that of this embodiment, the same effect as this embodiment is obtained. May be obtained.

  Furthermore, the present embodiment is not limited to the mobile phone 10 but may be applied to smartphones and PDAs (Personal Digital Assistants).

  The specific numerical values such as the fixed time and the predetermined time given in the present specification are merely examples, and can be appropriately changed according to the needs of the product specifications and the like.
