The key operation detection unit 13 includes an input interface for the operation key 53 and the side key 53a. When the operation of pressing (pressing) or releasing the operation key 53 or the side key 53a is detected, a signal indicating the operation is generated. This signal is transmitted to the control unit 10.

  The sound control unit 14 generates an analog sound signal from the sound collected by the microphone 141 based on the control of the control unit 10, and converts the analog sound signal into a digital sound signal. Further, when acquiring the digital audio signal, the audio control unit 14 converts the digital audio signal into an analog audio signal based on the control of the control unit 10, and outputs the analog audio signal from the speaker 142.

  Based on the control of the control unit 10, the wireless communication unit 15 performs spectrum despreading processing on the received signal received from the base station via the antenna 15 a to restore data. This data is transmitted to the audio control unit 14 and output from the speaker 142 according to an instruction from the control unit 10, transmitted to the display control unit 12, displayed on the display 52, or recorded in the storage unit 16. . In addition, the wireless communication unit 15 acquires sound data collected by the microphone 141, data input by the operation keys 53 and the side keys 53 a, and data stored in the storage unit 16 based on the control of the control unit 10.

  The storage unit 16 serves as a work area for the control unit 10 and the wireless communication unit 15, and its function can be realized by a RAM (Random Access Memory) or the like. In addition, a predetermined time measured by a timer 18 described later is stored in advance. The predetermined time may be fixed or may be set by the user.

  The information storage medium 17 (a computer-readable medium) stores programs, data, and the like, and its function can be realized by a hard disk, a memory (ROM: Read Only Memory), or the like. The information storage medium 17 stores a program for causing the computer to function as each unit of the present embodiment (a program for causing the computer to execute processing of each unit), a plurality of applications such as the applications 17A, 17B, and the like. .

  The timer 18 obtains a predetermined time stored in the storage unit 16 at the same time as the operation key 53 is pressed when the operation type of the key is not uniquely determined in the state of the activated application (described later). Start up and time. Depending on whether or not the key being pressed is released during the measurement time of the timer 18, the operation type of the key operation described later can be determined.

  The data table storage unit 20 stores two tables, a key code table 201 and an application state table 202. An example of the key code table 201 is shown in FIG. 3, and an example of the application status table 202 is shown in FIG.

  The key code table 201 assigns and stores key codes when the operation key 53 and the side key 53a are short-pressed, long-pressed, and double-clicked. Although only the A key, B key, and C key are shown in FIG. 3, other keys may have the same specifications. For example, when the A key is pressed, the key code A is assigned when pressed shortly, the key code a is assigned when pressed long, the key code AA is assigned when double-clicked, and the application 17A, 17B,. Specifically, for example, a decision key is assigned with a decision key code when pressed for a short time, a code for another screen transition key when pressed for a long time, and a mail key code when double-clicked.

  The application state table 202 has at least one of key operation types (“short press”, “long press”, and “double click”) that can be processed according to the state of the activated application such as a standby state or a web browsing state. Store). The “state A” in FIG. 4 is, for example, when the mobile phone 1 is in a standby state, and can be processed for all types of operations such as “short press”, “long press”, and “double click”. The state A applies to almost all states of the mobile phone 1. “State B” is, for example, a state during a call, and only the operation type “short press” can be processed. “State C” can be processed only for the operation type “long press”.

  The control unit 10 includes a CPU (Central Processing Unit), and is an arithmetic device that performs overall control of the mobile phone 1 and performs various other arithmetic processing and control processing. The function of the control unit 10 can be realized by hardware such as various processors (CPU, DSP, etc.), ASIC (gate array, etc.), and programs. The control unit 10 performs various processes of the present embodiment based on a program (data) stored in the information storage medium 17.

  The control unit 10 includes a key press / release detection unit 101, a key code determination unit 102, a key event notification unit 103, an application state determination unit 104, an application state acquisition unit 105, and an operation type determination unit 106. The key press / release detection unit 101 detects that the user has pressed a predetermined operation key 53 or side key 53a, or has released the pressing operation key 53 or side key 53a. The application status acquisition unit 105 acquires the “status” of the currently activated applications 17A, 17B... From the information storage medium 17. The application state determination unit 104 corresponds to the “state” of the applications 17A, 17B,... Acquired by the application state acquisition unit 105 with reference to the application state table 202 (FIG. 4) in the data table storage unit 20. Determine the key operation type that can be processed. The operation type determination unit 106 determines the operation type corresponding to the user's key operation based on the current “state” of the applications 17A, 17B... And the operation type of the processable key corresponding to the current “state”. Is determined as one of “short press”, “long press”, and “double click”. The key code determination unit 102 determines the key code of the pressed operation key 53 or side key 53a with reference to the key code table 201 (FIG. 3) stored in the data table storage unit 20 in advance. The key event notification unit 103 notifies the currently activated application (for example, the application 17A) of the key code determined by the key code determination unit 102.

<Operation when pressing briefly in state A>
Next, the operation when the user “short presses” the operation key 53 or the side key 53a in the mobile phone 1 whose application state is “state A” will be described with reference to FIG.

  Assume that the application 17A is activated. When the user presses the A key of the side key 53a (step S101), the key operation detection unit 13 notifies the control unit 10 that the A key has been pressed, and the key press / release detection unit 101 in the control unit 10 , It is detected that the A key has been pressed (step S103). Next, the application state acquisition unit 105 requests the state of the activated application 17A to the information storage medium 17, and acquires that it is “state A” (step S107). Next, the application state determination unit 104 refers to the application state table 202 in the data table storage unit 20 and determines a processable operation type (short press, long press, double click) corresponding to the state A (step S109). ). Next, the control part 10 starts the timer 18 (step S110).

  If the user releases the A key that the user has pressed while measuring the timer 18 (step S111), the key operation detection unit 13 notifies the control unit 10 that the A key has been released, and the key press / release detection unit. 101 detects that the A key has been released (step S112). When the timer 18 finishes timing up to a predetermined time stored in the storage unit 16 and stops (step S113), the operation type determination unit 106 corresponds to the state A determined by the application state determination unit 104 in step S109. Refer to the types of operations that can be processed. Then, the operation type determination unit 106 determines that the operation type is “short press” based on the detection of the release of the A key during the time of the timer 18 (step S114). Next, the key code determination unit 102 refers to the key code table 201 in the data table storage unit 20 based on the fact that the operation type determination unit 106 determines “short press” in step S114, and sets the key code to “key”. Code A "is determined (step S115). Next, the key event notification unit 103 notifies the application 17A of a press event that means that the key code A has been pressed and a release event that means that the key code A has been released (step S117). The application 17A performs processing corresponding to the press event and release event of the key code A notified from the key event notification unit 103 (step S119).

<Operation when long pressing in state A>
Next, the operation when the user “holds down” the operation key 53 or the side key 53a in the mobile phone 1 whose application state is “state A” will be described with reference to FIG. In the operation of FIG. 6, it is assumed that the application 17A is activated, and the operations from step S201 to step S210 of FIG. 6 (the operation type that can be processed corresponding to the state A is acquired after pressing the A key, and the timer The operation until starting 18) is the same as the operation from step S101 to step S110 at the time of the short press described above, and the description thereof is omitted.

  When the A key is not released while the timer 18 is activated, and the timer 18 finishes counting up to a predetermined time stored in the storage unit 16 and stops (step S211), the operation type determination unit 106 determines the application state in step S209. Reference is made to the processable operation type corresponding to state A, which is determined by unit 104. Then, the operation type determination unit 106 determines that the operation type is “long press” based on the fact that the release of the A key is not detected within the predetermined time (step S213). Next, the key code determination unit 102 refers to the key code table 201 in the data table storage unit 20 based on the fact that the operation type determination unit 106 determines “long press” in step S213, and sets the key code to “key”. It is determined as “code a” (step S215). Next, the key event notification unit 103 notifies the application 17A of a press event that means that the key code a has been pressed and a release event that means that the key code a has been released (step S217). The application 17A performs event processing for the key code a notified from the key event notification unit 103 (step S219).

  When the A key is released after the timer 18 is stopped (step S221), the key operation detecting unit 13 notifies the control unit 10 that the A key has been released, and the key press / release detecting unit 101 detects the A key. Is detected (step S223). However, since the timer 18 is stopped and the key event notification unit 103 has already notified the key event (key code a) to the application 17A, the key press / release detection unit 101 releases the detected A key. Is discarded (step S225).

<Operation when double-clicking in state A>
Next, the operation when the user “double-clicks” the operation key 53 or the side key 53a in the mobile phone 1 whose application state is “state A” will be described with reference to FIG. In the operation of FIG. 7, it is assumed that the application 17A is activated, and the operations from Step S301 to Step S310 of FIG. 7 (the processable operation type corresponding to the state A is acquired after pressing the A key, and the timer The operation until starting 18) is the same as the operation from step S101 to step S110 at the time of short pressing and from step S201 to step S210 at the time of long pressing, and thus the description thereof is omitted.

  When the A key is released while the timer 18 is activated (step S311), the key press / release detection unit 101 detects the release of the A key (step S313), and the control unit 10 resets the timer 18 and activates again. (Step S314). Immediately thereafter, when the A key is pressed again (step S315), the key press / release detector 101 detects the release of the A key (step S317). When the timer 18 finishes timing up to a predetermined time stored in the storage unit 16 and stops (step S319), the operation type determination unit 106 performs processing corresponding to the state A determined by the application state determination unit 104 in step S309. Browse possible operation types. The operation type determination unit 106 determines that the operation type is “double click” based on the fact that the key press / release detection unit 101 detects the release and press of the A key while the timer 18 is measuring (step S321). . Next, the key code determination unit 102 in the control unit 10 refers to the key code table 201 in the data table storage unit 20 based on the fact that the operation type determination unit 106 determines “double click” in step S321, and performs key The code is determined to be “key code AA” (step S323). Next, the key event notification unit 103 notifies the application 17A of a press event that means that the key code AA has been pressed and a release event that means that the key code AA has been released (step S325). The application 17A performs event processing of the key code AA notified from the key event notification unit 103 (step S327).

  When the A key is released after the timer 18 is stopped (step S329), the key operation detection unit 13 notifies the control unit 10 that the A key has been released, and the key press / release detection unit 101 detects the A key. Is detected (step S331). However, since the timer 18 is stopped and the key event notification unit 103 has already notified the key event (key code AA) to the application 17A, the key press / release detection unit 101 releases the detected A key. Is discarded (step S333).

  If the A key is not pressed after the A key is released in step S311, the operation type determination unit 106 may determine that the operation type is “short press”.

<Operation when pressing briefly in state B>
Next, the operation when the user “short presses” the operation key 53 or the side key 53a in the mobile phone 1 whose application state is “State B” such as during a call will be described with reference to FIG.

  Assume that the application 17A is activated. When the user presses the A key with the operation key 53 or the side key 53a (step S401), the key operation detecting unit 13 notifies the control unit 10 that the A key has been pressed, and the key press / release in the control unit 10 is performed. The detection unit 101 detects that the A key has been pressed (step S403). Next, the application state acquisition unit 105 requests the state of the activated application 17A from the information storage medium 17, and acquires “state B” (step S407). Next, the application state determination unit 104 refers to the application state table 202 in the data table storage unit 20 and determines a processable operation type (short press) corresponding to the state B (step S409). Since the state of the application 17A is “state B”, only the operation type “short press” is processed from the process types that can be processed corresponding to the state B (FIG. 4) determined by the application state determination unit 104 in step S409. Can not. Therefore, the operation type determination unit 106 determines that the operation type is “short press” (step S411). Next, the key code determination unit 102 refers to the key code table 201 in the data table storage unit 20 based on the determination that the operation type determination unit 106 determines “short press”, and sets the key code to “key code A”. Determination is made (step S413). Next, the key event notification unit 103 notifies the application 17A of a press event that means that the key code A has been pressed (step S415).

  When the user releases the A key (step S417), the key operation detection unit 13 notifies the control unit 10 that the A key has been released, and the key press / release detection unit 101 detects that the A key has been released. (Step S419). Next, the key event notification unit 103 notifies the application 17A of a release event that means that the key code A has been released (step S421). The application 17A performs an event process for the key code A notified from the key event notification unit 103 (step S423).

  Since only the operation type of “short press” can be processed in the state B, unlike the above-described state A, it is not necessary to use the timer 18 for determining long press, short press, or double click. Thereby, the response time from the control unit 10 to the application 17A is shortened.

<Operation when long pressing in state C>
Next, the operation when the user “holds down” the operation key 53 or the side key 53a in the mobile phone 1 whose application state is “state C” will be described with reference to FIG.

  Assume that the application 17A is activated. When the user presses the A key with the operation key 53 or the side key 53a (step S501), the key operation detecting unit 13 notifies the control unit 10 that the A key has been pressed, and the key press / release in the control unit 10 is performed. The detection unit 101 detects that the A key has been pressed (step S503). Next, the application state acquisition unit 105 requests the state of the activated application 17A from the information storage medium 17, and acquires “state C” (step S507). Next, the application state determination unit 104 refers to the application state table 202 in the data table storage unit 20 and determines a processable operation type corresponding to the state C (step S509). Since the state of the application 17A is “state C”, only the operation type “long press” is processed from the process types (FIG. 4) that can be processed corresponding to the state C, which is determined by the application state determination unit 104 in step S509. Can not. Therefore, the operation type determination unit 106 determines that the operation type is “long press” (step S511). Next, the key code determination unit 102 refers to the key code table 201 in the data table storage unit 20 based on the determination that the operation type determination unit 106 determines “long press”, and sets the key code to “key code a”. Determination is made (step S513). Next, the key event notification unit 103 notifies the application 17A of a press event that means that the key code a has been pressed (step S515).

  When the user releases the A key (step S517), the key operation detection unit 13 notifies the control unit 10 that the A key has been released, and the key press / release detection unit 101 detects that the A key has been released. (Step S519). Next, the key event notification unit 103 notifies the application 17A of a release event that means that the key code a has been released (step S521). The application 17A performs event processing of the key code a notified from the key event notification unit 103 (step S523).

  Since only the operation type “long press” can be processed in the state C, unlike the state A described above, it is not necessary to use the timer 18 for distinguishing between the long press and the short press. Thereby, the response time from the control unit 10 to the application 17A is shortened.

  As described above, according to the present invention, the operation type determination unit 106 in the control unit 10 determines the operation type (short press, long press, double click, etc.) of the operation key 53 or the side key 53a, and the key code determination unit 102. However, a plurality of key codes corresponding to a plurality of operation types are determined on the basis of the key code table 201 which is provided in advance. Therefore, the key code corresponding to the key can be assigned on the control unit 10 side for each operation type regardless of the number and type of keys, and the application side does not need to determine the corresponding key code. No need to modify the app even if the type is different depending on the model.

  In addition, the application state acquisition unit 105 in the control unit 10 acquires the current application state, and depending on the acquired application state, for example, only a short key press can be processed, and the control unit 10 side has a restriction. Only simple key operations can be enabled. Therefore, easy-to-use key operations can be realized.

<Modification>
A modification of the above operation will be described with reference to FIG. When the user presses a predetermined key, the control unit 10 starts key processing (step S2001). The control unit 10 performs a corresponding process depending on whether or not each event has occurred (step S2003).

  When a key press event occurs in step S2003 (a), the control unit 10 acquires a key code notified for each operation (step S2101). When there is only one type of key code to be notified regardless of the operation depending on the state of the application (“Yes” in step S2103), the control unit 10 notifies the key press event, turns on the key press flag (step S2105), The process returns to step S2003. When there are two or more types of key codes to be notified (“No” in step S2103), the control unit 10 confirms whether the timer 18 for double click detection is activated (step S2107). If the timer 18 is activated (“Yes” in step S2107), the control unit 10 stops the timer 18 (step S2109), and obtains and sets a key code for double clicking (step S2111). And the control part 10 notifies a key press event and a key release event to an application (step S2005), and returns to the process of step S2003. When the timer 18 is stopped (“No” in step S2107), the control unit 10 acquires the state of the application (step S2113). When there are two or more types of key codes to be notified for each operation except for invalid keys depending on the application state (“No” in step S2115), the control unit 10 acquires the long press detection time and measures the time by the timer 18 Is started (step S2117), and the process returns to step S2003. If the key code is one type (“Yes” in step S2115), the process returns to step S2105.

  When a timer expiration event occurs in step S2003 (b), the control unit 10 checks whether the long press detection timer 18 has expired or the double click detection timer 18 has expired (step S2201). ). If the long press detection timer 18 has expired, the control unit 10 acquires and sets the key code for the long press (step S2203). When the double-click detection timer 18 has expired, the control unit 10 acquires and sets a key code for a short press (step S2205). Regardless of whether the key code is acquired and set for both long press and short press, the process proceeds to step S2005.

  When a key release event occurs in step S2003 (c), the control unit 10 checks whether or not the long press detection timer 18 is activated (step S2301). When the long press detection timer 18 is activated (“Yes” in step S2301), the control unit 10 stops the timer 18 (step S2303) and acquires a key code to be notified for each operation (step S2305). When the key code acquired in step S2305 is different between the short press and the double click (“Yes” in step S2307), the control unit 10 acquires the detection time of the double click and starts the timer 18 (step S2309). The process returns to step S2003. If the key code acquired in step S2305 is the same for the short press and double click (“No” in step S2307), the control unit 10 sets the key code for the short press (step S2311), and the process of step S2005 I do.

  When the long press detection timer 18 is stopped (“No” in step S2301), if the key press flag is ON (“Yes” in step S2313), the control unit 10 notifies the application of a key release event. Then, the key press flag is turned OFF (step S2315), and the process returns to step S2003. When the key press flag is not ON (“No” in step S2313), the control unit 10 discards the key release event (step S2317) and returns to the process of step S2003.

  If no event occurs in step S2003 ("No" in step S2003), the control unit 10 ends the key process (step S2007).

  Although the embodiments of the present invention have been described in detail with reference to the drawings, the specific configuration is not limited to these embodiments, and includes design changes and the like within a scope that does not depart from the gist of the present invention. .

  For example, in the above-described embodiment, the application state such as the standby state or the web browsing state is acquired and the corresponding processable operation type is determined for the activated application, but the type of application is acquired, A corresponding processable operation type may be determined.
