Description

  The present invention relates to a mobile terminal device and a program, and more particularly to a technique preferably applied to an input interface in a mobile terminal device equipped with a touch panel.

  2. Description of the Related Art In recent years, touch panels with large screens that are intuitive, easy to understand, and easy to see have been installed in mobile terminal devices such as mobile phones and PDAs (Personal Digital Assistants). In such a portable terminal device, there is an advantage that even a user unfamiliar with the operation of the keyboard, the keypad, etc. can easily operate by using the touch panel.

  On the other hand, the range in which a user moves his / her finger by operating a mobile terminal device equipped with a touch panel is wider than that of a mobile terminal device using a conventional keyboard or keypad, and can be operated with one hand. Has a heavy user load. For this reason, an operation with both hands is inevitably caused when trying to perform a stable operation without causing fatigue of the finger when selecting an object or the like far from the position of the finger, or a pressing error.

  In this way, stable operation of a mobile terminal device equipped with a touch panel inevitably requires both hands, but in reality, the user can use the mobile terminal device while walking or holding on a strap in a train. It is often operated with one hand. That is, a mobile terminal device equipped with a touch panel is not a mobile terminal device with high operability for a user unless it can be stably operated with one hand like a mobile terminal device using a keyboard, a keypad, or the like. .

  For example, Patent Document 1 discloses an information processing apparatus that can be easily held and can be displayed optimally for the user without causing the user to be particularly conscious. The information processing apparatus has a flat housing having a substantially rectangular parallelepiped shape, and pressure sensors on the sheet are provided on both side surfaces of the housing across the main display. Based on the output of the pressure sensor, the main display Display control is performed.

  In the above portable terminal device, the operation mode switching means switches to the one-hand operation mode when the resistance value measured by the resistance value measurement means falls below the threshold value when the operation mode is the two-hand operation mode, and the operation mode is the one-hand operation. When the resistance value measured by the resistance value measuring means exceeds the threshold value in the mode state, the mode may be switched to the two-hand operation mode.

  The portable terminal device may include a threshold update unit that accumulates the resistance value measured by the resistance value measurement unit and updates the threshold using the accumulated resistance value data.

  In the mobile terminal device described above, the one-handed operation mode may display the display content displayed on the entire display screen in a reduced size and accept the user's operation content for the reduced display.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is an external view of a mobile phone according to an embodiment of the present invention. The mobile phone 1 according to the present embodiment is a mobile terminal device equipped with a touch panel as an input interface. A touch panel 5 is provided on the surface of the display, and a speaker 4 and a microphone 3 are respectively arranged at the upper part and the lower part of the display. In the present invention, a plurality of electrodes are provided, and the operation mode is switched based on the resistance value when the electrodes are energized. In the present embodiment, the first electrode 7 is placed on the touch panel 5, The two electrodes 8 are respectively arranged on both sides of the terminal housing 2 (long side portions where the microphone 3 and the speaker 4 are not arranged). In addition, the 2nd electrode 8 may be the surface of any housing | casing which does not become the same surface as a display, for example, may be provided in the housing | casing surface of the back side of a display.

  FIG. 2 is a hardware configuration diagram of the mobile phone according to the embodiment of the present invention. The cellular phone 1 includes a CPU (Central Processing Unit) 11, a wireless unit 12, a RAM (Random Access Memory) 13, a ROM (Read Only Memory) 14, a voice processing unit 15, an input processing unit 16, a display processing unit 17, and a resistance value. It has a measurement unit 18, a microphone 3, a speaker 4, a touch panel 5, a display 6, a first electrode 7, and a second electrode 8.

  The CPU 11 controls the overall operation of the mobile phone 1. Specifically, the CPU 11 reads a program and data from the ROM 14 when the mobile phone 1 is activated and thereafter, and executes the program using the RAM 13. For example, the CPU 11 performs various processes based on reception data acquired from the wireless unit 12, audio data acquired from the audio processing unit 15, input signals acquired from the input processing unit 16, and the like. Then, as processing results, transmission data to be output to the wireless unit 12, audio data to be output to the audio processing unit 15, image data to be output to the display processing unit 17, and the like are generated.

  The radio unit 12 performs radio signal processing and realizes radio communication with another communication device such as a base station. Specifically, the radio unit 12 demodulates and decodes a signal received via an antenna mounted on the mobile phone 1 and outputs the obtained reception data to the CPU 11. In addition, the wireless unit 12 encodes and modulates transmission data acquired from the CPU 11 and outputs a transmission signal obtained via an antenna.

  The RAM 13 is a memory that temporarily stores programs executed by the CPU 11 and data used for processing. In the RAM 13, at least a part of various programs and data is temporarily stored by the CPU 11. Further, the data stored in the RAM 13 by the CPU 11 is appropriately updated. Note that another type of volatile memory may be used instead of the RAM 13.

  The ROM 14 is a memory that stores programs executed by the CPU 11 and data used for processing. The ROM 14 stores in advance a program for executing an operation mode switching process based on a measured resistance value unique to the present invention, and various programs for realizing a communication function and a display control function. The ROM 14 stores various data used together with these programs such as a threshold value used for the operation mode switching process based on the measured resistance value, and these various data can be updated. Instead of the ROM 14, other types of non-volatile memories such as a flash memory may be used.

  The audio processing unit 15 performs audio signal processing. Specifically, the audio processing unit 15 acquires an audio analog signal from the MIC 3, performs necessary signal conversion processing, and outputs audio data to the CPU 11. The audio processing unit 15 acquires audio data from the CPU 11, performs necessary signal conversion processing, and causes the speaker 4 to reproduce audio.

  The input processing unit 16 performs input operation processing by the user. Specifically, when there is a touch operation on the touch panel 5, the input processing unit 16 is in contact (dutch down event), the object that has been in contact is released (dutch up event), the current touch An input signal indicating the position coordinates and the like is output to the CPU 11. It means that you are dragging from the Dutch Down event to the Dutch Up event. While dragging, the coordinates of the current touch position are output periodically (for example, every 50 milliseconds). However, you may make it output the coordinate of a touch position irregularly according to a touch condition.

  The display processing unit 17 performs image display processing. Specifically, the display processing unit 17 acquires image data from the CPU 11 and displays it on the display 6. The image displayed on the display 6 includes, for example, contents such as a document, a still image, and a moving image in addition to a menu screen.

  The resistance value measuring unit 18 measures a resistance value when a current flows between the first electrode 7 and the second electrode 8. The first electrode 7 and the second electrode 8 are arranged as shown in FIG. 1, and when the user operates the terminal, a current flows between both electrodes as shown in FIG. For example, when the user is operating with one hand, current flows between both electrodes through the hand as shown in FIG. 4A, and when the user is operating with both hands, both the hands, arms and torso are passed through. A current flows between the electrodes.

  FIG. 3 is a functional configuration diagram of the mobile phone according to the embodiment of the present invention. The cellular phone 1 according to the present embodiment is a functional unit for the CPU 11 to read an operation program specific to the present embodiment stored in the ROM 14 and perform an operation mode switching process based on a resistance value when energizing between both electrodes. The control unit 100 is configured. The control unit 100 logically includes a resistance value data acquisition unit 110, an operation mode switching unit 120, and a threshold update unit 130. Each means may be realized by software as described above, or may be realized by hardware using a circuit or the like.

  The resistance value data acquisition unit 110 acquires data on the resistance value between the first and second electrodes measured by the resistance value measuring unit 18. The operation mode switching unit 120 acquires the threshold value stored in the ROM 14, compares the resistance value data acquired by the resistance value data acquisition unit 110 with the threshold value, and switches the operation mode based on the comparison result. The operation mode includes a one-hand operation mode for the user to operate the terminal with one hand and a two-hand operation mode for the user to operate the terminal with both hands. The threshold update unit 130 accumulates resistance value data acquired by the resistance value data acquisition unit 110 in a memory such as a ROM or a RAM, and updates the threshold using the accumulated data.

  FIG. 5 is a flowchart showing an operation mode switching process according to the embodiment of the present invention. First, the user performs a touch operation on the touch panel 5 as an input operation on the display screen. At that time, a touchdown event occurs, and the input processing unit 16 notifies the CPU 11 of the touchdown event (step S101).

  The resistance value measurement unit 18 measures the resistance value when the first electrode 7 and the second electrode 8 are energized, and sends the measured resistance value data to the CPU 11. The resistance value data acquisition unit 110 of the control unit 100 configured on the CPU 11 acquires measured resistance value data from the resistance value measurement unit 18 (step S102).

  The operation mode switching unit 120 of the control unit 100 acquires resistance value threshold data stored in the ROM 14 (step S103), and the measured resistance value data (measured value) acquired in step S102 and the resistance value acquired in step S103. Are compared with the threshold data (threshold value) (step S104).

  When the measured value is less than the threshold value (step S104 / YES) and the current operation mode is the two-handed operation mode (step S105 / YES), the operation mode switching unit 120 determines that the user's operation state is the one-handed operation, Is switched to the one-handed operation mode (step S106). If the current mode is the one-handed operation mode (step S105 / NO), the one-handed operation mode is continued.

  On the other hand, when the measured value is equal to or greater than the threshold value (step S104 / NO) and the current one-handed operation mode is selected (step S106 / YES), the operation mode switching unit 120 determines that the user's operation state is an operation with both hands, Switching from the operation mode to the two-hand operation mode is performed (step S108). If the current mode is the two-handed operation mode (step S107 / NO), the two-handed operation mode is continued.

  Then, the threshold value updating unit 130 of the control unit 100 updates the threshold value data of the resistance value used for determining the operation state of the user (Step S109). In a case where the user is performing a two-hand operation, it is also conceivable that the fingertip of the hand holding the housing touches the touch panel and the user mistakenly recognizes the one-hand operation mode. However, the case where the finger comes into contact in this way is very rare, and means for canceling the one-handed operation mode manually may be provided. In addition, assuming such misrecognition, it may be designed such that no electrode is arranged in a range near the boundary between the touch panel and the housing that are easily touched by a finger. That is, instead of providing the electrode (first electrode 7) on the entire touch panel, it may be provided in a part.

  FIG. 6 is a flowchart showing threshold update processing according to the embodiment of the present invention. The threshold update unit 130 of the control unit 100 acquires past accumulated measurement data stored in the RAM 13 (step S201). The past measurement data may be stored in the ROM 14. When storing the measurement data in the RAM 13 of the volatile memory, the accumulated data is erased every time the power is turned off, and the measurement data is accumulated only when the power is turned on, but if the measurement data is stored in the ROM 14 of the nonvolatile memory, Even when the power is turned off, the measurement data is stored without being erased.

  Then, the threshold updating unit 130 adds the current measurement data to the past accumulated measurement data acquired in step S201 (step S202), and from the past accumulated measurement data, the peak value during one-handed operation and the two-handed operation time. Is determined (step S203, step S204). Then, an intermediate value between the two peak values is updated as a threshold value (step S205).

  A temporary threshold value (initial value) is set at the start of use of the mobile phone 1, but the threshold value is updated as the user uses it. Note that the initial value may be set in advance (at the time of shipment from the manufacturer) or may be set by the user. The former is preferable when the individual difference is small in the resistance value when holding one hand or both hands, and the latter is suitable when the individual difference is large and the initial value cannot be determined.

  Thereafter, as described above, in order to obtain an optimum threshold value for the user who is operating the mobile phone 1, the threshold value is updated each time the resistance value is measured and measurement data is acquired during the user's input operation. . As shown in FIG. 7, the accumulated measurement data is obtained by counting the appearance frequency for each measurement value so that the resistance value measured with the highest frequency can be grasped. It is held in the ROM 14.

  In the embodiment of the present invention, two examples are assumed as the one-hand operation mode. One is to reduce the screen and display it as an operation screen, and the other is to display a cursor and allow the user to operate the cursor.

  FIG. 8 is an explanatory diagram of a processing example (screen reduction display) in the one-handed operation mode and the two-handed operation mode according to the embodiment of the present invention. In this one-hand operation mode, as shown in FIG. 8 (a), in addition to the normal screen (L coordinate system) displayed on the entire display, a reduced screen (S coordinate system) reduced on the normal screen as the operation screen. ) Is displayed.

  The one-handed operation mode is a process as shown in FIG. When the two-handed operation mode is switched to the one-handed operation mode, the display processing unit 17 creates an image for reduced display output based on the image displayed on the normal screen (L coordinate system), and displays the reduced screen (S coordinate system). It is displayed (S1-1). After the input operation (touch operation) to the reduced screen is performed by the user, the input processing unit 16 acquires the user operation (S1-2). The coordinate data acquired here is coordinate data of the L coordinate system. Then, the input processing unit 16 converts the acquired coordinate data of the L coordinate system into coordinate data of the S coordinate system, and sends it to the CPU 11 (S1-3).

  The CPU 11 performs processing for input to the coordinate data received from the input processing unit 16, that is, coordinate data converted into the S coordinate system (S1-4). Then, the display processing unit 17 displays the process (input result) for the input executed by the CPU 11 on the normal screen and the reduced screen (S1-5).

  In the one-handed operation mode of FIG. 8, the mobile phone 1 is made to recognize the operation on the reduced screen by coordinate conversion from the L coordinate system to the S coordinate system, and input processing is performed using the coordinate data of the returned S coordinate system. By doing so, the operation on the reduced screen is reflected as the operation on the normal screen. In other words, the user can obtain the same effect as performing the input operation on the normal screen only by performing the input operation on the reduced screen without particular awareness.

  Note that the two-hand operation mode is a general process as shown in FIG. After switching from the one-handed operation mode to the two-handed operation mode and the user performing an input operation on the normal screen, the input processing unit 16 acquires the user operation (L coordinate system) and sends it to the CPU 11 (S1-11). . CPU11 performs the process with respect to the input to the coordinate data received from the input process part 16 (S1-12). And the display process part 17 displays the process with respect to the input performed by CPU11 (input result) on a normal screen (S1-13).

  FIG. 9 is an explanatory diagram of a processing example (cursor operation) in the one-handed operation mode and the two-handed operation mode according to the embodiment of the present invention. In this one-handed operation mode, as shown in FIG. 9A, a cursor is displayed on the display, and the touch panel 5 is used like a touch pad in a PC or the like to cause the user to operate the cursor.

  The one-handed operation mode is a process as shown in FIG. When the two-hand operation mode is switched to the one-hand operation mode, the display processing unit 17 displays a cursor on the screen (S2-1). After the input operation (touch operation) to the reduced screen is performed by the user, the input processing unit 16 acquires the user operation (S2-2), and converts the input content by the acquired user operation into a cursor operation. , It is sent to the CPU 11 (S2-3).

  The CPU 11 performs processing for input to the operation data received from the input processing unit 16, that is, operation data converted into a cursor operation (S2-4). Then, the display processing unit 17 displays the process for the input executed by the CPU 11 (input result (including cursor movement and the like)) on the screen (S2-5).

  In the one-handed operation mode of FIG. 9, by converting the user input into a cursor operation, the user makes the mobile phone 1 recognize the operation on the cursor, and the operation on the user's cursor is reflected as the operation on the screen. In other words, the user can obtain the same effect as performing the input operation on the screen only by performing an operation on the cursor without being particularly conscious.

  Note that the two-hand operation mode is a general process as shown in FIG. After switching from the one-handed operation mode to the two-handed operation mode and the user performing an input operation on the normal screen, the input processing unit 16 acquires the user operation and sends it to the CPU 11 (S2-11). The CPU 11 performs processing for input to the coordinate data received from the input processing unit 16 (S2-12). And the display process part 17 displays the process (input result) with respect to the input performed by CPU11 on a screen (S2-13).

Specific means are realized by using actual hardware. That is, when the computer (CPU 11) reads and executes a program from a predetermined recording medium (ROM 14), the above-mentioned means are loaded onto the main storage device and generated.

  The program executed by the mobile phone 1 according to the present embodiment may be stored on a computer connected to a network such as the Internet and provided by being downloaded via the network. Further, the program may be provided or distributed via a network such as the Internet.
