  Hereinafter, preferred embodiments of a portable terminal and a key input method according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram showing an embodiment of a mobile terminal according to the present invention. A mobile terminal 1 shown in FIG. 1 is physically a mobile phone including, for example, a CPU (Central Processing Unit), a memory, a communication interface, a hard disk, and the like. On the front surface of the housing 2 of the mobile terminal 1, for example, a touch panel display 3 is provided.

  Further, a plurality of side keys 4 (seven left and right in the present embodiment) are provided on the left and right side surfaces of the housing 2. The side key 4 is a part that receives a pressing operation by the user, and is assigned an auxiliary operation different from the operation by the touch panel display 3, for example. Each side key 4 is assigned a number (identification information) for identification. 1-No. 7, No. 7 in order from the upper right side of the housing 2. 8-No. 14

  FIG. 2 is a diagram illustrating functional components of the mobile terminal 1. As shown in the figure, the mobile terminal 1 includes, as functional components, a detection unit 10 including a posture detection unit 101 and a pressure detection unit 102, a threshold setting unit 103, a threshold storage unit 104, and an input recognition unit. 105.

  The attitude detection unit 101 is a part that detects the attitude of the housing 2 of the mobile terminal 1. The posture detection unit 101 includes, for example, a three-axis acceleration sensor, and detects whether the housing 2 is oriented vertically or horizontally. The posture detection unit 101 outputs posture information indicating the detection result to the threshold setting unit 103 or the input recognition unit 105.

  The pressure detection unit 102 is a part that detects a stroke pressure applied to the side key 4. The pressure detection unit 102 includes a plurality of pressure sensors, for example, and detects the stroke pressure for each side key 4. The pressure detection unit 102 outputs the pressure information indicating the detection result together with the identification information for identifying the side key 4 to the threshold setting unit 103 or the input recognition unit 105.

  The threshold value setting unit 103 is a part for setting a threshold value of the stroke pressure for each side key 4. More specifically, the threshold setting unit 103 implements a setting mode in which the stroke pressure applied to the plurality of keys is simultaneously detected by the pressure detection unit, triggered by a predetermined operation by the user.

  In the setting mode, for example, as shown in FIG. 3, an operation guide is displayed on the touch panel display 3 toward the user so that the user grips the casing 2 in a portrait orientation and presses the side key 4 in that state. The Next, for example, as shown in FIG. 4, the operation guide is displayed on the touch panel display 3 toward the user so that the user grips the casing 2 in a state of being turned sideways and presses the side key 4 in that state.

  The threshold value setting unit 103 acquires the pressure information associated with the identification information of the side key 4 from the pressure detection unit 102 and stores the pressure information in the threshold value storage unit 104 for each of the case 2 in the vertical direction and the horizontal direction. FIG. 5 is a diagram illustrating an example of information stored in the threshold storage unit 104.

  In the example shown in FIG. 5, the threshold storage unit 104 stores No. 1 as identification information of the side key 4. 1-No. 15, the stroke pressure threshold value of each side key 4 when the casing 2 is in the vertical orientation and the stroke pressure threshold value of each side key 4 when the casing 2 is in the lateral orientation are stored. .

  In the case where the housing 2 is in the vertical orientation, for example, No. No. 2 side key 4 has a stroke pressure threshold of “800 g”, No. 2 No. 4 side key 4 has a stroke pressure threshold of “500 g”, No. 4 No. 5 side key 4 stroke pressure threshold is “300 g”, No. 5 No. 6 side key 4 has a stroke pressure threshold value of “100 g”, no. The threshold value of the stroke pressure of the side key 4 of “9” is “500 g”. The other side keys are “no input”.

  On the other hand, in the case where the housing 2 is sideways, for example, No. No. 4 side key 4 has a stroke pressure threshold of “500 g”, No. 4 No. 6 side key 4 has a stroke pressure threshold of “500 g”, The threshold value of the stroke pressure of the 12 side keys 4 is “600 g”. The other side keys are “no input”.

  The input recognition unit 105 is a part that recognizes an input by the side key 4 based on the above-described threshold value of the stroke pressure. When the pressure detection unit 102 detects that the stroke pressure is applied to the side key 4, the input recognition unit 105 first acquires the posture information of the housing 2 from the posture detection unit 101. Next, the input recognition unit 105 refers to the threshold storage unit 104 based on the identification information, pressure information, and posture information of the side key 4. And the input recognition part 105 recognizes the input of the side key 4 when the stroke pressure added to the side key 4 is more than a threshold value.

  On the other hand, when the stroke pressure applied to the side key 4 is less than the threshold value, the input recognition unit 105 does not recognize the input of the side key 4. Further, the input recognition unit 105 inputs the side key 4 for the side key 4 whose stroke pressure threshold value is “no input” even when the stroke pressure is detected by the pressure detection unit 102. Does not recognize.

  Subsequently, the operation of the mobile terminal 1 having the above-described configuration will be described. FIG. 6 is a flowchart showing a procedure for setting a threshold value of the stroke pressure. FIG. 7 is a flowchart showing a side key recognition procedure.

  When setting the threshold value of the stroke pressure, as shown in FIG. 6, first, the attitude of the housing 2 is detected (step S01: attitude detection step). Next, an operation guide is displayed on the touch panel display 3. Then, for each of the state in which the housing 2 is oriented vertically and the state in which the housing 2 is oriented horizontally, simultaneous detection of stroke pressure applied to each side key 4 when the user grips the housing 2 is performed (step S02). The stroke pressure for each side key 4 is set as a threshold value (step S03: threshold value storing step, threshold value setting step).

  When actually operating the side key 4 set as described above, as shown in FIG. 7, first, the stroke pressure applied to the pressed side key 4 is detected (step S04: pressure detection step). Next, it is detected whether the posture of the housing 2 is vertical or horizontal (step S05), and a threshold value is referred to based on the detected posture and stroke pressure (step S06).

  After referring to the threshold, an input recognition step is performed. In the input recognition step, it is determined whether or not a threshold value is set for the side key 4 pressed first (step S07). When no threshold is set for the side key 4, the side key 4 is in a disabled state, and the process ends without recognizing the input.

  If a threshold value is set for the side key 4, it is determined whether or not the detected stroke pressure is greater than or equal to the threshold value (step S08). If the stroke pressure is less than the threshold, the input is not recognized and the process ends. On the other hand, if the detected stroke pressure is greater than or equal to the threshold value, the input is recognized (step S09). In this case, the portable terminal 1 executes a predetermined process corresponding to the side key 4 being pressed.

  As described above, in the portable terminal 1 and the key input method, the threshold value of the stroke pressure is set for each of the plurality of side keys 4 provided on the side surface of the housing 2, and the stroke pressure is equal to or higher than the threshold value. When the key is pressed, the input by the side key 4 is recognized. Therefore, the side key 4 that is actually used can be flexibly set according to the grip position of the user and the stroke pressure at the time of key input, so that the usability of key input can be improved.

  In the portable terminal 1 and the key input method, the posture of the housing 2 is detected, and the stroke pressure threshold value for each side key 4 is stored in association with the posture of the housing 2. Depending on the attitude of the housing 2, the grip position and stroke pressure vary greatly even for the same user. Therefore, by providing a threshold value for the stroke pressure for each side key 4 in association with the attitude of the housing 2, the usability of key input can be further improved.

  In the portable terminal 1 and the key input method, the stroke pressure applied to the side key 4 is detected all at once, and the threshold value of the stroke pressure for each side key 4 is set based on the detection result. Thereby, the threshold value of the stroke pressure of each side key 4 can be easily set based on the grip position and the stroke pressure when the user actually grips the housing 2.

  Further, in the portable terminal 1 and the key input method, for the side key 4 for which no threshold is set, the input by the side key 4 is recognized even when the stroke pressure applied to the side key 4 is detected. It is supposed not to. As described above, by invalidating the side keys 4 other than the grip position, it is possible to prevent the side keys 4 from being erroneously operated.

  The present invention is not limited to the above embodiment. For example, in the embodiment described above, the side keys 4 are arranged on the left and right side surfaces of the housing 2, but the arrangement of the keys is not limited to this, and the grip position according to the shape and dimensions of the housing 2 is not limited. Can be changed as appropriate. Further, the side key 4 is not limited to the push button type but may be a touch panel type. Further, in the above-described embodiment, the threshold value of the stroke pressure of the side key 4 is set by causing the user to actually grip the housing 2. However, the threshold value manually input by the user may be accepted. .
