<First embodiment>
Referring to FIG. 1, mobile terminal 10 includes a touch panel 36 controlled by a CPU (also referred to as a processor or a computer) 20, a key input device 22, and a touch panel control circuit 34. The CPU 20 controls the wireless communication circuit 14 and outputs a call signal. The output call signal is transmitted from the antenna 12 and transmitted to the mobile communication network including the base station. When the other party performs a response operation, a call ready state is established.

  When a call end operation is performed by the key input device 22 or the touch panel 36 after the transition to the call enabled state, the CPU 20 controls the wireless communication circuit 14 to transmit a call end signal to the other party. After transmitting the call end signal, the CPU 20 ends the call process. Also when the call end signal is received from the other party first, the CPU 20 ends the call process. Also, the CPU 20 ends the call process when a call end signal is received from the mobile communication network regardless of the call partner.

  When a call signal from a call partner is captured by the antenna 12 while the mobile terminal 10 is activated, the wireless communication circuit 14 notifies the CPU 20 of an incoming call. The CPU 20 controls the LCD monitor 26 by the LCD driver 24 and causes the video RAM 28 to store images necessary for drawing, thereby causing the LCD monitor 26 to display the caller information described in the incoming call notification. Further, the CPU 20 outputs a ring tone from an incoming call notification speaker (not shown).

  In the call ready state, the following processing is executed. The modulated audio signal (high frequency signal) sent from the other party is received by the antenna 12. The received modulated audio signal is subjected to demodulation processing and decoding processing by the wireless communication circuit 14. The received voice signal thus obtained is output from the speaker 18. The transmitted voice signal captured by the microphone 16 is subjected to encoding processing and modulation processing by the wireless communication circuit 14. The modulated audio signal generated thereby is transmitted to the other party using the antenna 12 as described above.

The touch panel 36 is a pointing device for the user to specify an arbitrary position within the screen of the LCD monitor 26. When the touch panel 36 is operated by pressing, sliding (striking), or touching the upper surface with a finger, the touch panel 36 detects the operation. When the touch panel 36 detects a touch, the touch panel control circuit 34 specifies the position of the operation and outputs coordinate data of the operated operation position to the CPU 20. That is, the user can input an operation direction, a figure, or the like to the mobile terminal 10 by pressing, sliding, or touching the upper surface of the touch panel 36 with a finger.

  In addition, the touch panel 36 detects a finger touching the touch panel 36 by a method called a capacitance method that detects a change in capacitance between electrodes generated when the finger approaches the surface of the touch panel 36. The touch panel 36 employs a projection-type capacitance method that detects a change in capacitance between electrodes caused by the approach of a finger by forming an electrode pattern on a transparent film or the like. Yes. The detection method may be a surface type capacitance method, a resistance film method, an ultrasonic method, an infrared method, an electromagnetic induction method, or the like.

  Here, an operation in which the user touches the upper surface of the touch panel 36 with a finger is referred to as “touch”. On the other hand, the operation of releasing the finger from the touch panel 36 is referred to as “release”. The coordinates indicated by the touch are referred to as “touch start point”, and the coordinates of the operation end position indicated by the release are referred to as “touch end point”. Further, an operation in which the user touches the upper surface of the touch panel 36 and subsequently releases it is referred to as a “touch operation”. The operation on the touch panel 36 is not limited to a finger, and may be performed with a stick having a thin tip such as a pen. In addition, a dedicated touch pen or the like may be provided to perform the operation.

  When touching with a finger, the touch position is the center of gravity in the area of the finger touching the touch panel 36. However, when the touch position is the center of gravity of the area of the finger touching the touch panel 36, the area of the touching finger may change even if the user does not intend. Therefore, even if the user recognizes that the touch position has not been moved, the CPU 20 detects that the touch position has moved. Therefore, the CPU 20 determines that the touch position has not changed if the amount of movement of the touch position is very small (for example, 10 dots or less of the LCD monitor 26).

  2A to 2C are illustrative views showing an appearance of the mobile terminal 10. Referring to FIGS. 2A to 2C, the mobile terminal 10 has a case C1 and a case C2 each formed in a plate shape. The thickness of case C1 and case C2 is substantially the same. In FIG. 2, the microphone 16 (not shown) is built in the case C2, and the speaker 18 is built in the case C1. The opening op2 leading to the built-in microphone 16 is provided on one upper surface in the length direction of the case C2, and the opening op1 leading to the built-in speaker 18 is provided on one upper surface in the length direction of the case C1. That is, the user listens to the sound output from the speaker 18 through the opening op1 and inputs the sound to the microphone 16 through the opening op2.

  The key input device 22 is provided on the upper surface of the case C2. The user operates the key input device 22 or the touch panel 36 to perform a call start / end operation, a power on / off operation of the mobile terminal 10, and the like. The LCD monitor 26 is attached so that the monitor screen is exposed on the upper surface of the case C 1, and a touch panel 36 is provided on the upper surface of the LCD monitor 26.

  Case C1 and case C2 incorporate an opening / closing mechanism (not shown). The case C1 is movable in the length direction of the case C2 while being stacked on the case C2. Furthermore, the opening / closing mechanism includes an assist mechanism that assists the case C1 with a spring mechanism or the like.

Further, the state shown in FIG. 2A is referred to as a “closed state”, and the state shown in FIGS. 2B and 2C is referred to as an “open state”. Then, the CPU 20 detects the open state and the closed state by a magnetic sensor and a magnet (not shown).

  Note that the case C1, the LCD monitor 26, the touch panel 36, the opening op1, and the case C1 are not illustrated in detail in the other illustrations for the sake of simplicity.

  The portable terminal 10 has a TV viewing function. When an operation for executing the TV viewing function is performed by the key input device 22 or the touch panel 36, the LCD monitor 26 displays an image by digital broadcasting. Specifically, the DTV tuner 42 extracts a digital broadcast signal corresponding to the selected channel from the digital broadcast signal received by the antenna 44. Further, the DTV tuner 42 performs processing such as digital demodulation on the extracted digital broadcast signal to generate a demodulated signal. Further, the DTV tuner 42 outputs a demodulated signal to the mobile terminal 10. The mobile terminal 10 performs a decoding process based on the MPEG system on the demodulated signal to form a video signal. Then, the formed video signal is output to the LCD monitor 26, and the LCD monitor 26 displays a video by digital broadcasting of the selected channel.

  3A and 3B are illustrative views showing the appearance of the mobile terminal 10 that executes the TV viewing function. With reference to FIGS. 3A and 3B, the LCD monitor 26 displays a TV area R1, an operation area R2, and a state display area R3. The TV area R1 is an area in which an image by a digital broadcast being received is displayed. The operation area R <b> 2 is an area that includes keys operated by the user in the TV viewing function, and includes a menu key 50, a channel key 52, and a volume key 54. The menu key 50 is a key for displaying a GUI for ending the TV viewing function or changing the setting. The channel key 52 is a key for selecting a channel of the digital broadcasting being received (changing the channel number). The user can increase the channel number 52 indicating the upward direction and decrease the channel number using the channel key 52 indicating the downward direction. The volume key 54 is a key for adjusting the volume corresponding to the digital broadcast displayed in the TV area. The user increases the volume by the volume key 54 indicated by “+” and decreases the volume by the volume key 54 indicated by “−”.

  Further, the TV viewing function includes a feedback function that, when operated by the touch panel 36, feeds back the operation to the user by motor vibration by the motor 40. For example, when the user selects a channel with the channel key 52, the CPU 20 rotates the motor 40 in accordance with the channel selection process, and vibrates the mobile terminal 10 by the rotation of the motor 40. Each time the user selects a channel with the channel key 52, the mobile terminal 10 vibrates, that is, is fed back, so that the user can know that the channel selection operation is successful.

  It should be noted that the feedback function may be executed every time the touch panel 36 is operated in addition to the TV viewing function. Furthermore, the vibration by the motor 40 may be used as a vibration function for notifying the user of an incoming call. The feedback function may output not only the vibration of the motor 40 but also sound from a speaker (not shown).

  The state display region R3 is a region where the state of the mobile terminal 10 is displayed, and includes icons indicating the radio wave reception state and the battery remaining state of the mobile terminal 10.

Further, the upper right end of the LCD monitor 26 in the horizontal direction is set to the specific position A. Since the specific position A will be described later in another embodiment, a detailed description thereof is omitted here. Furthermore, the CPU 20 detects that the mobile terminal posture of the mobile terminal 10 has changed from acceleration data (acceleration data) output from the acceleration sensor 38 and switches the display direction of the LCD monitor 26. For example, when the mobile terminal orientation of the mobile terminal 10 changes from the horizontal orientation shown in FIG. 3A to the vertical orientation shown in FIG. 3B, the display direction of the LCD monitor 26 matches the change in the mobile terminal orientation. Thus, the horizontal direction can be switched to the vertical direction. Since the specific position A is always the same position on the LCD monitor 26, the lower right end of the LCD monitor 26 is the specific position A in the vertical direction.

  Note that the TV area R1, the operation area R2, and the state display area R3 are the same in the other illustrations, and therefore detailed explanations are omitted in the other illustrations for simplicity. Further, the display contents of the TV area R1 are also omitted.

  3C and 3D are illustrative views showing a state in which the mobile terminal 10 is held by the user when the TV viewing function is executed. FIG. 3C is a diagram of holding the mobile terminal 10 in the horizontal state, and FIG. 3D is a diagram of holding the mobile terminal 10 in the vertical state. In both of FIGS. 3C and 3D, the user can hold the side of the portable terminal 10 with his / her finger so that his / her finger does not touch the touch panel 36 and misoperate. The terminal 10 is held.

  However, when the user enjoys digital broadcasting for a long time using the TV viewing function, if the user holds the side of the portable terminal 10 with his / her finger as shown in FIG. 3C or FIG. Is tired of hands and cannot withstand long viewing. As shown in FIGS. 4A and 4B, the portable terminal 10 is held for a long time by holding the upper surface of the case C1 and the lower surface of the case C2, as shown in FIGS. However, since the finger touches the operation region R2 or the like, unnecessary tuning or volume adjustment is performed. Moreover, since the touch panel 36 is substantially the same size as the upper surface of the case C1, it is difficult to hold the touch panel 36 so as not to touch the touch panel 36 and to sandwich the upper surface of the case C1 and the lower surface of the case C2.

  Therefore, by performing a specific operation on the specific area, an insensitive area that invalidates the operation corresponding to each key is set in the touch reaction area on the touch panel 36, thereby preventing an erroneous operation on the touch panel 36. Note that the touch reaction area has the same coordinates as the display area of the LCD monitor 26.

  Specifically, the specific area is set by operating the specific area as the operation area R2 and performing a specific slide operation on the operation area R2. For example, if the mobile terminal posture is in the horizontal direction, referring to FIG. 5A, if a slide operation is performed with the thumb from the bottom to the operation region R2, all of the touch reaction regions are set as insensitive regions. Can be set. Furthermore, in the vertical direction, referring to FIG. 5B, when the slide operation is performed with the thumb from the right to the left with respect to the operation region R2, all of the touch reaction regions can be set as insensitive regions. . Since the insensitive area remains set until the thumb is released from the touch panel 36 after the slide operation, erroneous operations on the menu key 50, the channel key 52, and the volume key 54 in the operation area R2 are prevented. Furthermore, it is possible to easily set the insensitive area simply by performing a specific slide operation.

  FIG. 6 is an illustrative view showing a memory map of the RAM 32. Referring to FIG. 6, a memory map 300 of RAM 32 includes a program storage area 302 and a data storage area 304. A part of the program and data is read from the flash memory 30 all at once or partially and sequentially as necessary, stored in the RAM 32, and processed by the CPU 20 or the like.

  The program storage area 302 stores a program for operating the mobile terminal 10. A program for operating the mobile terminal 10 includes a TV viewing program 310 and a touch panel control program 312. However, the touch panel control program 312 includes an operation result determination program 312a.

  The TV viewing program 310 is a program for viewing a digital broadcast on the mobile terminal 10. The touch panel control program 312 is a program for processing a touch on the touch panel 36 and the like. However, the operation result determination program 312a is a program for determining whether or not the operation after the touch is a specific operation.

  In addition, although illustration is abbreviate | omitted, the program for operating the portable terminal 10 contains a telephone call control program etc.

  As shown in FIG. 7, a touch position buffer 330 is provided in the data storage area 304. The data storage area 304 stores touch coordinate map data 332, specific area coordinate data 334, specific position coordinate data 336, touch position integration data 338, dead area coordinate data 340, and GUI data 342, and a touch flag. 344, a mobile terminal attitude flag 346, a specific operation flag 350, an operation counter 352, a release counter 354, and the like are provided. However, the GUI data 342 includes key area data 342a.

  The touch position buffer 330 is a buffer for temporarily storing an input result such as a touch detected by the touch panel 36, and stores, for example, coordinate data of a touch start point, a touch end point, and a current touch position. The touch coordinate map data 332 is data for associating a position such as a touch specified by the touch panel control circuit 38 with a display position of the LCD monitor 26. Therefore, the CPU 20 can associate the position of the touch operation specified by the touch panel control circuit 38 with the display on the LCD monitor 26 based on the touch coordinate map data 332.

  The specific area coordinate data 334 is the coordinate data of the specific area. In the first embodiment, the specific area coordinate data 334 is the same coordinate data as the display area of the operation area R2. The specific area coordinate data 334 may be the same as the coordinate data indicating the display area of the LCD monitor 26. The specific position coordinate data 336 is the coordinate data of the specific position A shown in FIGS. 3A and 3B, and indicates the upper right end in the display coordinates of the LCD monitor 26 in the horizontal direction of FIG. Coordinate data.

  The touch position integration data 338 is data obtained by integrating the coordinate data of the detected touch position between the touch and release. The insensitive area coordinate data 340 is area coordinate data of the insensitive area set in the touch reaction area, and in this embodiment, coincides with the coordinate data of the touch response area on the touch panel 36. In place of the touch position integration data 338, the touch position is recorded as needed, and touch position record data composed of accumulated touch position data, touch position history data composed of touch position history data, and the like. There may be.

  The GUI data 342 is GUI coordinate data displayed on the LCD monitor 26, and the key area data 342a is composed of coordinate data in the display area of operation keys such as the menu key 50, the channel key 52, and the volume key 54. .

The touch flag 344 is a flag for determining whether or not the touch panel 36 is touched (touched). For example, the touch flag 344 is composed of a 1-bit register. When the touch flag 344 is established (turned on), the data value “1” is set in the register, and when the touch flag 344 is not established (turned off), the data value “0” is set in the register.

  The mobile terminal attitude flag 346 is a flag for determining whether the mobile terminal attitude of the mobile terminal 10 is the horizontal direction or the vertical direction. For example, the mobile terminal attitude flag 346 is configured by a 1-bit register. If the mobile terminal 10 is in the horizontal direction as shown in FIG. 3A, the mobile terminal attitude flag 346 is established (turned on), and the data value “1” is set in the register. On the other hand, if the mobile terminal 10 is in the vertical orientation as shown in FIG. 3B, the mobile terminal attitude flag 346 is not established (turned off), and the data value “0” is set in the register.

  The slide direction flag 348 is a flag for determining whether the slide operation is vertical or horizontal. For example, the slide direction flag 348 is composed of a 1-bit register. If the sliding direction is the horizontal direction, the sliding direction flag 348 is established (turned on), and a data value “1” is set in the register. On the other hand, if the slide direction is the vertical direction, the slide direction flag 348 is not established (turned off).

  The specific operation flag 350 is a flag for determining whether or not a specific operation has been performed. For example, the specific operation flag 350 is composed of a 1-bit register. When the specific operation flag 350 is established (turned on), the data value “1” is set in the register, and when the specific operation flag 350 is not established (turned off), the data value “0” is set in the register. .

  The operation counter 352 is a counter for counting the time after the touch is detected by the touch panel 36. The measurement result of the operation counter 352 is used to determine whether or not the operation time is longer than the threshold value T. The release counter 354 is a counter for counting the time since the insensitive area was set and released. The measurement result of the release counter 354 is used to determine whether or not to release the dead area.

  Although illustration is omitted, the data storage area 304 stores image files and the like, and is provided with other counters and flags necessary for the operation of the mobile terminal 10. Each counter and flag is set to “0” in the initial state.

  The CPU 20 executes, in parallel, a plurality of tasks including a touch panel control process shown in FIGS. 8 and 9 and an operation result determination process shown in FIG. 10 under the control of a multitask OS such as μITRON and Symbian.

  For example, when the user touches the touch panel 36 of the mobile terminal 10, as shown in FIG. 8, the CPU 20 starts a touch panel control process, and determines whether or not the touch is made in step S1. That is, in step S1, it is determined whether or not the touch flag 344 is on. If “NO” in the step S1, that is, if the touch flag 344 is turned off, the determination in the step S1 is repeatedly executed. On the other hand, if “YES” in the step S1, that is, if the touch flag 344 is turned on, a touch position recording process is executed in a step S3. That is, in step S 3, the coordinate data of the current touch position stored in the touch position buffer 330 is recorded as touch position integrated data 338.

  Subsequently, in step S5, it is determined whether or not a slide operation is being performed. That is, in step S5, it is determined whether or not the coordinate data of the current touch position stored in the touch position buffer 330 has changed. If “YES” in the step S5, that is, if a slide operation is being performed, the process returns to the step S3.

Here, the processes of steps S3 and S5 are repeated within about 10 ms.
3, the coordinate data of the current touch position is recorded as touch position integration data 338 only once in 10 repetitions. This is because if the coordinate data is recorded about every 10 ms, the data amount of the touch position integrated data 338 increases, and the storage capacity of the RAM 32 is compressed. That is, when the processes of steps S3 and S5 are repeated, the coordinate data of the touch position is recorded as the touch position integrated data 338 about every 100 ms.

On the other hand, if “NO” in the step S5, that is, if the slide operation is not being performed, an operation time calculating process is executed in a step S7. That is, in step S7, the time from when the touch is detected until the slide operation ends is calculated as the operation time. Specifically, coordinate data of the accumulated touch position recorded in the accumulated touch position data 338 is used. As described above, the coordinate data of the touch position is recorded as the touch position integration data 338 every about 100 ms. Therefore, the touch is started from the number of integrated touch position integration data 338 and the time when the coordinate data is integrated. The operation time from can be calculated.
Here, the operation counter 352 counts the number of accumulated data included in the touch position accumulated data 338. Then, as shown in Equation 1, the operation time can be calculated by obtaining the product of the operation counter 352 and the time over which the coordinate data is integrated.

    [Equation 1] Operation time = (Operation counter 352) × (Time during which coordinate data is integrated) For example, since the time during which coordinate data is integrated is about 100 ms, the value of the operation counter 352, that is, the touch position integrated data. If the number of accumulated data included in 338 is “3”, it can be calculated from Equation 1 that approximately 300 ms has elapsed since the touch was detected.

  Note that the operation time may be calculated by executing a time loop process at the same time as the touch flag 344 is turned on. Specifically, the operation counter 352 counts the number of times the time loop process is repeated, and the operation time is calculated from the product of the processing time of the time loop process and the operation counter 352.

  Subsequently, in step S9, it is determined whether or not the operation time is equal to or greater than a threshold value T. That is, in step S9, it is determined whether or not the operation time from the detection of the touch until the end of the slide operation is equal to or greater than the threshold value T. Here, the threshold T is set to 500 ms. Therefore, in step S9, it is determined whether or not the operation time from the start of the touch operation by the user until the end of the slide operation is 500 ms or longer. The threshold T may be 500 ms or more, or may be less than 500 ms.

  If “NO” in the step S9, that is, if the operation time is less than 500 ms, the process returns to the step S3. On the other hand, if “YES” in the step S9, that is, if the operation time is 500 ms or longer, an operation result determining process is executed in a step S11. That is, in step S11, it is determined whether or not the slide operation performed by the user is a specific operation. If there is a specific operation, the specific operation flag 350 is turned on. The operation result determination process will be described in detail with reference to the flowchart of the operation result determination process shown in FIG.

Subsequently, in step S13, it is determined whether or not the specific operation is performed. That is, it is determined whether or not the specific operation flag 350 is on. If “NO” in the step S13, that is, if the specific operation flag 350 is turned off, the process proceeds to a step S19. On the other hand, if “YES” in the step S13, that is, if the specific operation flag 350 is turned on, the insensitive area is set in a step S15. That is, the coordinate data of the touch reaction area is recorded as the insensitive area coordinate data 340. Subsequently, in step S17, feedback is prohibited and the process proceeds to step S31. That is, in step S17, the operation of the feedback is prohibited by stopping the operation of the motor 40.

  Here, in step S19, that is, if “NO” in step S13, it is determined whether or not the touch position is within the key area. That is, it is determined whether or not the coordinate data of the current touch position is included in the key area data 342a such as the menu key 50, the channel key 52, and the volume key 54. If “YES” in the step S21, for example, if the coordinate data of the current touch position is within the key area of the channel key 52, an operation process corresponding to the key is executed in a step S21, and the process proceeds to the step S23. That is, assuming that the channel key 52 is operated, the channel number of digital broadcasting is changed. On the other hand, if “NO” in the step S19, that is, if the coordinate data of the current touch position is not included in any operation key area, the process proceeds to the step S23.

  Subsequently, in step S23, it is determined whether or not it has been released. That is, it is determined whether or not the touch flag 344 is off. If “NO” in the step S23, that is, if the touch flag 344 is turned on, the accumulated coordinate data and the operation counter 352 included in the touch position accumulated data 388 are reset, and the process returns to the step S3. On the other hand, if “YES” in the step S23, that is, if the touch flag 344 is turned off, the accumulated coordinate data and the operation counter 352 included in the touch position buffer 330 and the touch position accumulated data 388 are reset, and the step Return to S1.

  Referring to FIG. 9, in step S31, it is determined whether or not it has been released. That is, it is determined whether or not the touch flag 344 is off. If “NO” in the step S31, that is, if the touch flag 344 is turned on, the process of the step S31 is repeated. That is, after the dead area is set, the dead area remains set unless it is released from the touch panel 36. On the other hand, if “YES” in the step S31, that is, if the touch flag 344 is turned off, a release time calculating process is executed in a step S33. That is, in step S33, the time (release time) after the release from the touch panel 36 is calculated. Specifically, the count process is executed simultaneously with the touch flag 344 being turned off, and the release counter 354 is repeatedly counted. Then, the release time is calculated from the product of the repetition time of the count process and the release counter 354. Also, the release time calculation process ends when the touch flag 344 is turned on.

  Subsequently, in step S35, it is determined whether or not the release time is equal to or greater than a threshold value R. Here, the threshold value R is 1000 ms. Therefore, in step S35, it is determined whether or not the time after the user releases from the touch panel 36 is 1000 ms or more. The process of step S35 is executed at the same time as step S33 is executed, that is, whether or not the release time is equal to or greater than the threshold value R is determined as soon as step S33 is executed. The threshold value R may be 1000 ms or more, or may be less than 1000 ms.

  If “NO” in the step S35, that is, if the release time is less than the threshold value R, the process returns to the step S31. On the other hand, if “YES” in the step S35, that is, if the release time is equal to or greater than the threshold value R, the insensitive area is canceled in a step S37. That is, the dead area coordinate data 340 is reset.

  As a result, the user can easily release the insensitive area simply by removing the finger from the touch panel. Furthermore, if the release time is within a predetermined time, the insensitive area is not released even if the finger is removed from the touch panel 36, so that convenience for the user is improved.

Subsequently, in step S39, the feedback prohibition is canceled. That is, the motor 40 is operated. Then, the coordinate data accumulated in the touch position buffer 330, the touch position accumulated data 388, the operation counter 352, and the release counter 354 are reset, and the process returns to step S1.

  In other words, since the feedback operation is resumed in accordance with the release of the dead area, the user can clearly recognize the setting or the release state of the dead area.

  FIG. 10 is a flowchart showing the operation result determination process shown in step S11 (see FIG. 8). In step S51, the CPU 20 determines whether or not a slide operation has been performed within the specific area. That is, the coordinates of the touch start point and the current touch position stored in the touch position buffer 330 and the accumulated coordinate data included in the touch position accumulated data are within the area indicated by the specific area coordinate data 334. Determine whether it is included. Note that determination may be made based on whether or not all of the accumulated data included in the touch position integrated data 338 is included in the area indicated by the specific area coordinate data 334.

  If “NO” in the step S51, that is, if the slide operation is not performed in the specific area, the operation result determination process is ended, and the process returns to the touch panel control process shown in FIG. On the other hand, if “YES” in the step S51, that is, if the slide operation is performed within the specific area, the mobile terminal posture detecting process is executed in a step S53. That is, the acceleration sensor 38 determines whether the mobile terminal 10 is in the horizontal direction shown in FIG. 3A or the vertical direction shown in FIG. 3B. 346 is turned on, and the mobile terminal posture flag 346 is turned off if the direction is vertical. Subsequently, the slide direction is calculated in step S55. That is, the slide direction in the slide operation performed in the specific area is calculated. Specifically, the origin of the touch coordinate system on the touch panel 36 is the upper left corner in the mobile terminal 10 shown in FIG. 3B, the horizontal axis is the X axis, and the vertical axis is the Y axis. Thereby, the coordinates of the touch start point can be (x1, y1), and the coordinates of the current touch position can be (x2, y2).

  When the portable terminal 10 is in the vertical direction, if the equation shown in Formula 2 is satisfied, that is, if the amount of change in the Y-axis direction is larger than the amount of change in the X-axis direction, the slide direction is set to the vertical direction. If the equation shown in Equation 3 holds, that is, if the amount of change in the X-axis direction is larger than the amount of change in the Y-axis direction, the sliding direction is set to the horizontal direction.

  On the other hand, when the portable terminal 10 is in the horizontal direction, if the formula 2 is satisfied, the slide direction is the horizontal direction, and if the formula 3 is satisfied, the slide direction is the vertical direction.

    [Expression 2] | x1-x2 | <| y1-y2 | [Expression 3] | x1-x2 | ≧ | y1-y2 | For example, in the horizontal direction in FIG. Then, the slide direction becomes the vertical direction. On the other hand, in the vertical direction in FIG. 5B, when the thumb slides from the right to the left, the slide direction becomes the horizontal direction.

  Thus, the slide direction flag is turned on if the slide direction is the horizontal direction, and the slide direction flag is turned off if the slide direction is the vertical direction.

Subsequently, in step S57, it is determined whether or not the mobile terminal posture is horizontal. That is, it is determined whether or not the mobile terminal posture flag 346 is on. If “NO” in the step S57, that is, if the mobile terminal posture is in the vertical direction, the process proceeds to a step S65. On the other hand, if “YES” in the step S57, that is, if the mobile terminal posture is in the horizontal direction, it is determined whether or not the sliding direction is horizontal in a step S59. That is, it is determined whether or not the slide direction flag 348 is on. If “YES” in the step S59, that is, if the slide direction is the horizontal direction, the operation result determination process is ended.

  On the other hand, if “NO” in the step S59, that is, if the slide direction is the vertical direction, it is determined whether or not the slide distance is equal to or greater than the threshold S in a step S61. Here, the threshold value S is a distance of one third in the width direction of the LCD monitor 26 (see FIG. 2). That is, it is determined whether or not the distance of the slide by the user's slide operation is a distance of one third or more in the width direction of the LCD monitor 26. Further, the slide distance can be obtained by using the three-square theorem based on the touch start point and the coordinates of the current touch position. Note that the threshold value S may be larger or smaller than the one-third distance in the width direction of the LCD monitor 26.

  If “NO” in the step S61, that is, if the slide distance is less than the threshold S, the operation result determining process is ended. On the other hand, if “YES” in the step S61, that is, if the slide distance is equal to or greater than the threshold value S, the specific operation flag 350 is turned on in a step S63, and the operation result determining process is ended. That is, when the slide operation input by the user is in the horizontal direction when the mobile terminal is in the horizontal direction, the slide direction is the vertical direction in the operation region R2, that is, because of the specific relationship, the specific slide operation is specified. Judge as.

  Here, in step S65, it is determined whether or not the slide direction is vertical. That is, it is determined whether or not the slide direction flag 348 is off. If “YES” in the step S65, that is, if the slide direction flag 348 is turned off, the operation result determination process is ended. On the other hand, if “NO” in the step S65, that is, if the slide direction flag 348 is turned on, the process proceeds to a step S61. That is, when the mobile terminal posture is the vertical direction, the slide direction is the horizontal direction in the operation region R2, and therefore it is determined in step S61 whether or not the slide distance is greater than or equal to the threshold value S. Furthermore, if the slide distance is equal to or greater than the threshold value S, the specific operation flag 350 is turned on in step S63.

  As can be seen from the above description, the operation region R2 including the menu key 50, the channel key 52, and the volume key 54 is displayed on the LCD monitor 26 of the portable terminal 10. Then, when a slide operation as a specific operation is performed in the operation region R2, the operation region R2 can be set as a dead region. For example, the user sets the insensitive area by performing a slide operation so that the slide direction is the vertical direction in the operation area R2 when the mobile terminal posture is in the horizontal direction with respect to the touch panel 36. Can do.

  Thus, the user can set the insensitive area on the touch panel 36 only by performing a slide operation corresponding to the mobile terminal posture.

  In addition, since the slide operation that is easy for the user to operate can be determined as the specific operation in accordance with the mobile terminal posture in which the mobile terminal 10 is held, the user can easily operate the slide operation regardless of the mobile terminal posture. It can be performed.

  Then, by making the range in which the slide operation is determined as the specific operation only within the operation region R, the user can distinguish the slide operation that is the specific operation from the normal operation that operates the key.

  Although the specific operation is detected in the specific area (operation area R2), the specific operation may be determined using the touch panel reaction area as the specific area. The specific operation may be a slide operation for drawing a circle or a triangle. Furthermore, the threshold values T, R, and S used in the first embodiment are set to the same values in the other embodiments.

Further, when the touch panel 36 supports multi-point detection of touch, each touch is processed in parallel. Then, if the insensitive area is set to a part of the touch reaction area on the touch panel 36, the insensitive area is set by the first touch operation, and the second touch operation performed subsequently is performed outside the insensitive area. The key can be operated. That is, the user can operate the portable terminal 10 with the touch panel 36 even if the insensitive area is set.

<Second embodiment>
In the second embodiment, a process capable of arbitrarily setting the width of the dead area will be described. Further, in the second embodiment, the configuration of the mobile terminal 10 in FIG. 1 described in the first embodiment, an illustrative view showing the appearance of the mobile terminal 10 in FIG. 2, and the TV viewing function shown in FIGS. 3 and 4 are executed. An illustrative view showing the appearance of the mobile terminal 10, the memory map shown in FIG. 6, and the flowchart shown in FIG.

  In the second embodiment, the insensitive area can be set not by the specific area but by a slide operation from the specific position A. As shown in FIG. 11, when the mobile terminal is in the horizontal direction, a slide operation in which the slide direction is the horizontal direction is performed from the specific position A (see FIGS. 3A and 3B). As shown in FIG. 11B, in the Y-axis direction, the area from the specific position A to the coordinates of the current touch position is set as the insensitive area. The specific position A may be another vertex of the LCD monitor 26, and may be set to an arbitrary position by the user. Furthermore, instead of the specific position A, it may be a specific side. For example, it may be one side in the length direction of the LCD monitor 26 or the other side in the length direction.

  Further, in the second embodiment, the insensitive area is not canceled even if released. In order to cancel the insensitive area, the insensitive area can be canceled by performing a slide operation in which the sliding direction is the horizontal direction and releasing at the specific position A when the mobile terminal is in the horizontal direction. As a result, even if the insensitive area is set and then switched many times, the set insensitive area is not canceled, and the convenience for the user is improved.

  If the mobile device is in the vertical orientation, when a slide operation is performed in which the slide direction is the vertical direction from the specific position A, the insensitive area can be set according to the slide distance, and the insensitive area is canceled. In this case, a slide operation in which the slide direction is the vertical direction is performed so that the release point matches the specific position A.

  The CPU 20 executes in parallel a plurality of tasks including a touch panel control process shown in FIG. 12 and an operation result determination process shown in FIG. 13 under the control of a multitask OS such as μITRON and Symbian.

  When the user touches the touch panel 36 of the mobile terminal 10, the CPU 20 starts touch panel control processing. Here, since the process of steps S1-S9 (see FIG. 8) is the same as that of the first embodiment, detailed description thereof is omitted. When the process of step S9 is completed, referring to FIG. 12, in step S11, an operation result determination process is performed. The processing in step S11 is different from that in the first embodiment. Further, step S11 in the second embodiment will be described with reference to the flowchart of FIG. Subsequently, in step S13, it is determined whether or not the specific operation is performed. If “NO” in the step S13, that is, if it is not a specific operation, the processes of the steps S19 to S23 are performed in the same manner as in the first embodiment.

On the other hand, if “YES” in the step S13, that is, if it is a specific operation, in a step S81, it is determined whether or not it is released at a specific position A. That is, it is determined whether the touch end point stored in the touch position buffer 330 matches the coordinate data of the specific position coordinate data 336. If “NO” in the step S81, that is, if not released at the specific position A, a dead area is set in a step S87, and feedback is prohibited in a step S89. And if the process of step S89 is complete | finished, it will return to step S1 (refer FIG. 8). On the other hand, if “YES” in the step S81, that is, if released at the specific position A, the dead area is canceled in a step S83, and the feedback inhibition is canceled in a step S85. And if the process of step S85 is complete | finished, it will return to step S1.

  FIG. 13 is a flowchart showing the operation result determination process shown in step S11 (see FIG. 12) in the second embodiment. In step S111, the CPU 20 determines whether or not a slide operation has been performed within the specific area. If “NO” in the step S111, that is, if the slide operation is not performed within the specific area, the operation result determining process is ended. On the other hand, if “YES” in the step S111, that is, if the slide operation is performed in the specific area, it is determined whether or not the start position of the slide operation is the specific position A in a step S113. That is, it is determined whether or not the touch start point stored in the touch position buffer 330 matches the coordinate data of the specific position coordinate data 336.

  If “YES” in the step S113, that is, if the start position of the slide operation matches the specific position A, the process proceeds to a step S117. On the other hand, if “NO” in the step S113, that is, if the start position of the slide operation and the specific position A do not coincide with each other, it is determined in a step S115 whether or not the specific position A is released. If “NO” in the step S115, that is, if not released at the specific position A, the operation result determining process is ended, and the process returns to the touch panel control process shown in FIG. On the other hand, if “YES” in the step S115, that is, if released at the specific position A, a mobile terminal posture detecting process is performed in a step S117, and a slide direction calculating process is performed in a step S119.

  Subsequently, in step S121, it is determined whether or not the mobile terminal posture is horizontal. If “NO” in the step S121, that is, if the mobile terminal posture is the vertical orientation, the process proceeds to a step S129. On the other hand, if “YES” in the step S121, that is, if the mobile terminal posture is in the horizontal direction, it is determined whether or not the sliding direction is horizontal in the step S123. If “NO” in the step S123, that is, if the mobile terminal posture is in the horizontal direction and the slide direction is in the vertical direction, the operation result determination process is ended because it is not a specific operation.

  If “YES” in the step S123, that is, if the slide direction is the horizontal direction, it is determined whether or not the slide distance is equal to or greater than the threshold S in a step S125. If “NO” in the step S125, that is, if the slide distance is less than the threshold S, the operation result determining process is ended. On the other hand, if “YES” in the step S125, that is, if the slide distance is equal to or greater than the threshold value S, the specific operation flag 350 is turned on in a step S127, and the operation result determining process is ended. That is, when the mobile terminal posture is in the horizontal direction, if the slide distance is greater than or equal to the threshold value S and the slide direction is in the horizontal direction, it is determined as a specific operation.

  Here, in step S129, it is determined whether or not the slide direction is vertical. That is, when the mobile terminal posture is the vertical direction, it is determined whether or not the slide direction is the vertical direction. If “NO” in the step S1129, that is, if the slide direction is the horizontal direction, the operation result determination process is ended. On the other hand, if “YES” in the step S129, the process proceeds to a step S125. That is, when the mobile terminal posture is the vertical direction, if the slide distance is greater than or equal to the threshold value S and the slide direction is the vertical direction, it is determined as a specific operation.

  In step S87 (see FIG. 12), the area indicated by the specific position A and the current touch position (or touch end point) can be set as a dead area.

  Thus, if a specific operation (slide operation) in which the specific position A is the touch start point is performed, the insensitive area is set. If a specific operation (slide operation) in which the specific position A is the touch end point is performed, the insensitive area is set. The setting is canceled.

  As can be seen from the above description, in the process of step S11 in the second embodiment, the slide operation in which the touch start point or the touch end point is the specific position A is determined as the specific operation. Therefore, in the insensitive area setting process in step S87, the insensitive area can be set according to the slide distance. Further, when the slide operation is performed so that the specific position A is the end point, the dead area is canceled.

  That is, the insensitive area can be canceled simply by performing a slide operation so that the touch end point becomes the specific position A in the slide direction corresponding to the mobile terminal posture in which the mobile terminal 10 is held.

  As a result, when the user holds the mobile terminal so that the terminal posture of the mobile terminal and the sliding direction are in a predetermined relationship and performs a slide operation so that the end point is at the specific position, the insensitive area is displayed. It can be canceled. That is, the user can operate the touch panel by distinguishing between the operation for canceling the insensitive area and the operation for holding the mobile terminal.

  Further, the user can arbitrarily set the size of the insensitive area according to the slide distance of the slide operation.

  In the second embodiment, it may be determined that the specific operation is based only on the slide distance in the specific area without determining the mobile terminal posture, and the insensitive area may be set.

<Third embodiment>
In the third example, in the mobile terminal 10 including a plurality of touch switches instead of the touch panel, the setting of the insensitive area for each of the plurality of touch switches will be described.

  In the third embodiment, the configuration of the mobile terminal 10 is substantially the same as that of the first embodiment, but includes a touch switch TSW instead of the touch panel 36. The external appearance of the portable terminal 10 is also substantially the same as that of the first embodiment. However, referring to FIG. 14A, the touch switch TSW is composed of a plurality of touch switches A-F, and the LCD monitor 26. Is provided on the upper surface of the other side in the longitudinal direction of the case C1. The touch switches A-F included in the touch switch TSW are independent of each other, and each touch switch can detect a touch. In addition, the touch switches are arranged so as to be adjacent to each other, the touch switch A is adjacent to the touch switches B and F, the touch switch B is adjacent to the touch switches A and C, and the touch switch C is the touch switch B. , D, and touch switch D is adjacent to touch switches C, E.

  Touch switches A and B correspond to the volume adjustment keys of the first embodiment, and touch switches C and D correspond to the channel keys of the first embodiment. Further, the touch switches E and F which are not visually recognized are used for setting a dead area. When the touch switch TSW detects a touch, a feedback operation is performed by the motor 40 as in the first embodiment.

  The touch switches A-F included in the touch switch TSW detect a touch by a capacitive method, like the touch panel 36. Here, when a touch is detected by the touch switch A, a change in capacitance in the touch switch A will be described.

  FIG. 14B is a graph showing the amount of change in capacitance in touch switch A and touch switch B that are detecting a touch. In this graph, with the lower left as the origin, the horizontal axis represents position coordinates in the direction D (see FIG. 14A), and the vertical axis represents the amount of change in capacitance. Therefore, the amount of change in capacitance with respect to the position coordinate in the direction D can be read from this graph. From this graph, it can be seen that the finger is also touching the touch switch B, but since the amount of change of the touch switch A (the area of the hatched portion M) is the largest, it can be recognized that the touch switch A is touched. it can. Further, the amount of change in capacitance changes in a mountain shape, and the coordinate position in the largest direction D coincides with the center point of the touch switch A, so the center of the finger touched by the user (finger It can be seen that the center of gravity of the area is located at the center of the touch switch A.

  Here, an operation of sliding from the touched touch switch to the adjacent touch switch without releasing it is referred to as a “touch slide operation”. Further, the amount of change in the capacitance of the touch switch A-D changes as shown in FIG. Hereinafter, this will be specifically described with reference to FIG.

  FIG. 14C is an illustrative view showing a time change of the capacitance in the touch switch A to the touch switch D when the touch slide operation is performed from the touch switch A to the touch switch D. Referring to FIG. 14C, “A”-“D” correspond to the touch switches AD. Each graph corresponding to “A”-“D” is the same as the graph shown in FIG. 14B, and represents the amount of change in the capacitance of the touch switch AD with respect to the position coordinate in the direction D. The top four graphs represent the amount of change in the capacitance of the touch switch AD at the time Ti, and the graphs arranged in the vertical direction represent the time Δt, 2Δt, and 3Δt with respect to the time Ti. This represents the amount of change in capacitance of the subsequent touch switch AD. Further, the user performs a touch slide operation from the touch switch A to the touch switch D between time Ti and time (Ti + 3Δt).

  At time Ti, the user touches the touch switch A. In this case, the amount of change in capacitance of the touch switch A that has been touched becomes the largest, and the amount of change in capacitance also changes slightly in the adjacent touch switch B.

  Next, at the time when the touch slide operation is performed from the touch switch A to the touch switch B (Ti + Δt), the amount of change in the capacitance of the touch switch B becomes the largest, and the capacitance of the adjacent touch switches A and C also increases. The amount of change changes slightly. In the touch slide operation, the center of the user's finger moves from the center of the touch switch A to the center of the touch switch B, so that the position coordinate in the direction D changes without changing the shape of the mountain-shaped graph. become. That is, the CPU 20 can detect that the maximum value of the change amount of the capacitance detected by the touch switches A and B does not change, but the position coordinate in the direction D corresponding to the maximum value is changed. it can.

  Subsequently, at the time (Ti + 2Δt) when the touch slide operation is performed from the touch switch B to the touch switch C, the amount of change in the capacitance of the touch switch C becomes the largest, and the capacitance of the adjacent touch switches B and D also increases. The amount of change changes slightly. Then, the CPU 20 can detect a change in the position coordinate in the direction D corresponding to the maximum value of the change in capacitance detected by the touch switches B and C.

At the time (Ti + 3Δt) when the touch slide operation is performed from the touch switch C to the touch switch D, the amount of change in the capacitance of the touch switch D becomes the largest, and the amount of change in the capacitance also in the adjacent touch switch C. Changes a little. Then, the CPU 20 can detect the change in the direction D corresponding to the maximum value of the change amount of the capacitance detected by the touch switches C and D.

  That is, the CPU 20 detects that the touch slide operation has been performed by detecting that the position coordinate in the direction D corresponding to the maximum value in the detected change amount of the electrostatic capacitance remains constant. can do. Specifically, the CPU 20 performs a touch slide operation when the position coordinate in the direction D corresponding to the maximum value of the change in capacitance changes from the coordinate of a certain touch switch to the coordinate of an adjacent touch switch. Judge that there is.

  Therefore, in the third embodiment, when a touch slide operation is detected by any two touch switches, a dead area is set for the touch reaction area of the touch switch TSW. Specifically, touch switch A to touch switch B or touch switch F, touch switch B to touch switch A or touch switch C, touch switch C to touch switch B or touch switch D, touch switch D to touch switch C or touch If any one of the touch slide operations of the switch E, the touch switch E to the touch switch D, and the touch switch F to the touch switch A is performed, an insensitive area is set for the touch reaction area of the touch switch TSW.

  The configuration of the memory map in the RAM 32 of the third embodiment is almost the same as that of the first embodiment, but the program storage area 302 stores a touch switch control program instead of the touch panel control program 312. In the data storage area 304, a touch position buffer 330 is provided, touch coordinate map data 332 and touch position integration data 338 are stored, and a touch flag 344 and a release counter 354 are further provided.

  In the third embodiment, the touch position buffer 330 stores position coordinate data in the current direction D and the amount of change in capacitance. The touch coordinate map data 332 is data for converting the position of the touch detected by the touch switch TSW into position coordinates in the direction D. Then, every 100 ms, the data of the position coordinate data in the direction D and the amount of change in capacitance stored in the touch position buffer 330 is stored in the data storage area 304 as the touch position integrated data 338.

  The touch flag 330 is used to determine whether or not the touch switch TSW is touched. Further, since the configuration of the touch flag 330 is the same as that of the first embodiment, detailed description thereof is omitted. The release counter 354 is used to count the time since release.

  In addition to the processing described in the first embodiment, the CPU 20 executes a plurality of tasks including the touch switch control processing shown in FIG. 15 in parallel under the control of a multitask OS such as μITRON and Symbian.

  For example, when the user touches the touch switch TSW of the portable terminal 10, as shown in FIG. 15, the CPU 20 starts a touch switch control process, and determines whether or not the touch is made in step S181. That is, it is determined whether or not the touch flag 344 is on. If “NO” in the step S181, that is, if the touch flag 344 is turned off, the process of the step S181 is repeatedly executed. On the other hand, if “YES” in the step S181, that is, if the touch flag 344 is turned on, it is determined whether or not the slide is performed in a step S183. That is, in step S183, it is determined whether or not the accumulated position coordinates included in the touch position accumulated data 338 have changed.

If “NO” in the step S183, that is, if the slide is not performed, the step S2
Proceed to 01. On the other hand, if “YES”, that is, if sliding, it is determined in step S185 whether an adjacent switch has been operated. That is, it is determined whether or not an adjacent touch switch is operated by a touch slide operation. Specifically, in the accumulated data included in the touch position accumulated data 338, it is determined whether only the coordinate data of the touch position is changed while the maximum value of the change amount of the capacitance is constant.

  If “NO” in the step S185, that is, if the touch slide operation is not performed, an operation process corresponding to the switch is executed in a step S201, and the process returns to the step S181. For example, if the touch switch D for channel operation is touched, the channel number of the received digital broadcast is changed.

  If “YES” in the step S185, that is, if a touch slide operation is performed, a dead area is set in a step S187. That is, in step S187, a dead area is set for the touch reaction area of the touch switch TSW. Subsequently, in step S189, feedback is prohibited. That is, the operation of the motor 40 is stopped.

  Subsequently, in step S191, it is determined whether or not the touch is continued. That is, it is determined whether or not the touch flag 344 is on. If “YES” in the step S191, that is, if the touch flag 344 is turned on, the process of the step S191 is repeatedly executed. On the other hand, if “NO”, that is, if the touch flag 344 is OFF, a release time calculation process is executed in step S193, and it is determined whether or not the release time is equal to or greater than a threshold value R in step S195. In addition, since the process of step S193, S195 is the same as step S33, S35 (refer FIG. 9), detailed description is abbreviate | omitted.

  If “NO” in the step S195, if the release time is less than the threshold value R, the process returns to the step S191. On the other hand, if “YES”, if the release time is equal to or greater than the threshold value R, the dead area is canceled in step S197. That is, the insensitive area set for the touch reaction area of the touch switch TSW is canceled. Subsequently, in step S199, the feedback prohibition is canceled and the process returns to step S181. That is, in step S199, the motor 40 is restarted.

  As can be seen from the above description, even if the touch switch TSW is used instead of the touch panel 36, it is possible to detect that a specific operation has been performed on the touch switch TSW and set the insensitive area.

  In the third embodiment, the mobile terminal orientation is the horizontal direction. However, the mobile terminal orientation may be the vertical direction. If the touch slide operation is performed on the touch switch TSW, the insensitive area is set.

  Further, the communication method of the mobile terminal 10 is not limited to the CDMA method, but may be a W-CDMA method, a TDMA method, a PHS method, a GSM (registered trademark) method, or the like. Not only the portable terminal 10 but also a portable information terminal such as a PDA (Personal Digital Assistant) may be used.

Furthermore, in the present invention, the insensitive area is set by a specific operation on the specific area, and the input to the touch panel 36 is partially ignored so that the portable terminal 10 can be used. Then, when the insensitive area is set, the insensitive area is canceled by a specific operation on the specific area. Also, in order to prevent the operation for setting the insensitive area from affecting the key operation, etc., the normal key operation is not performed at the moment of touching, but when it is touched or released for a certain period of time. It is good also as a mechanism to be performed. As a result, there is an effect that the key operation is not performed even if the key area remains touched.
