Abstract

<P>PROBLEM TO BE SOLVED: To provide an input control method and an information processing device capable of quickly determining whether a key is pressed shortly when the key is pressed and of reducing power consumption. <P>SOLUTION: After pressing of a key is started, it is determined whether pressing of the key is continued or not (step S12g) by a short time interval (step S12c) for quickly determining whether the key is pressed shortly or not (step S12f and step S12h). After a lapse of the predetermined time (step S12g:YES), it is determined whether pressing of the key is continued or not (step S12m) by a long time interval (step S12j) for determining whether pressing of the key is continued for a long time or not (step S12k). In this way, power consumption is lowered. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to an input control method and an information processing apparatus, and more particularly to long-time input processing.

  In a small-sized device such as a mobile communication terminal device or a PDA (Personal Digital Assistant), a limited number of keys may be installed as an input device. On the other hand, because the device has abundant functions, when you press a key briefly, that is, when you press a normal length, when you press the key several times, when you press and hold that key And it is handled to mean different instructions.

  Therefore, an input control device is known that transmits different identifiers when a certain key is pressed a plurality of times and when the key is pressed for a long time. That is, when it is detected that a key has been pressed, the fact that the key has been pressed is transmitted, and then it is detected that the key has been pressed for a relatively long time (for example, 500 ms). , Send that the key was held down. If it is detected that the key is pressed after a relatively short time (for example, 100 ms) after transmitting that the key has been pressed once, the fact that the key has been pressed is transmitted again. The process which repeats is known (for example, refer patent document 1).

Further, a process for detecting whether or not a key is always pressed at a short time (for example, several tens of ms) interval is known. That is, when it is detected that a certain key has been continuously pressed for a number of times less than the predetermined number of times, it is transmitted that the key has been pressed for a short time, and a certain key has been continuously pressed for a number of times equal to or greater than the predetermined number of times. When it is detected that the key has been pressed across, it is a process of transmitting that the key has been pressed for a long time.
Japanese Patent Publication No. 6-46375 (first page, FIG. 1)

  However, in the method disclosed in Patent Document 1 described above, it is relatively long (for example, 500 ms) from when it is detected that a certain key is pressed until it is determined that the pressing is a short press. )). That is, when the press is a short press, it takes a long time to start processing corresponding to the short press of the small apparatus.

  In addition, the above-described method for detecting whether or not a key is always pressed at a short time interval has a problem that power consumption is large because the number of times of pressing detection increases. The problem is that a portable device such as a mobile communication terminal device is energized while it is energized, and a long press of a key is continued by an object touching the device regardless of the intention of the user. It is remarkable when it is done.

  The present invention has been made to solve the above problems. When a certain key is pressed, it can be determined that the pressing is a short press in a short time, and the input control consumes less power. It is an object to provide a method and an information processing apparatus.

  In order to achieve the above object, the input control method of the present invention starts the operation when the operation of the input element is started, and the second control method starts from the operation until the first predetermined time elapses. It is detected whether or not the input element is operated at a predetermined time interval. When it is detected that the input element is not operated, it is determined that the short-time operation has been completed and the operation is ended. Then, after the first predetermined time has elapsed since the start of the operation, it is detected that the operation of the input element has been performed, and after the first predetermined time has elapsed, a third predetermined time that is greater than the second predetermined time interval. Detecting whether or not the operation of the input element is being performed at intervals, and if it is detected that the operation of the input element is being performed, it is determined that the operation has been performed for a long time; If it is detected that no operation has been performed, the long-time operation ends. It is determined that, characterized in that the operation is ended.

  ADVANTAGE OF THE INVENTION According to this invention, when a certain key is pressed down, it can determine that the press is a short press in a short time, and can provide the input control method and information processing apparatus with low power consumption. .

  Embodiments of an input control method and an information processing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 shows a configuration of an information processing apparatus according to an embodiment of the present invention to which an input control method according to the embodiment of the present invention is applied. The information processing apparatus includes an input unit 11, an input control unit 12, a control unit 13, a first application system unit 14a, a second application system unit 14b,. . . And an nth application system unit 14n.

  The input unit 11 is an input device including one or a plurality of key switches as an input element, and transmits an interrupt to the control unit 13 when a key switch operation, that is, pressing is started. Further, it receives an inquiry about the identification information of the key switch being pressed from the input control unit 12, and transmits the identification information to the input control unit 12.

  The input control unit 12 starts an operation according to an instruction from the control unit 13 or restarts the operation. Then, the key switch receives the identification information of the pressed key switch transmitted from the input unit 11 by scanning the key, that is, by inquiring the identification information of the pressed key switch to the input unit 11, and the key switch And the key switch transmits “short press”, “long press”, or “release” to the control unit 13.

  Here, “short press” means that the key switch operation has started, “long press” means that the key switch has been operated for a long time, and “release” means that the key switch operation has been completed. It shows that each.

  Here, when the received identification information of the pressed key switch indicates a plurality of key switches, the input control unit 12 has received the information that there is no pressed key switch. It is assumed that there is no key switch. The key switch identification information transmitted from the input unit 11 and the key switch identifier transmitted to the control unit 13 may be the same information or different information.

  The control unit 13 controls the entire information processing apparatus. For example, receiving an interrupt, receiving the identifier of the key switch and the type of operation status transmitted from the input control unit 12, operating each unit according to the identifier and type, receiving information from each unit, or , Send information to each part.

  The first to nth application system units 14a to 14n are application system units installed in the information processing apparatus, which are activated by the control unit 13 and receive information transmitted from the control unit 13. , Operate according to that information.

  Next, the operation of the input control unit 12 will be described. FIG. 2 shows a flowchart of the operation of the input control unit 12. FIG. 3 shows an example of the operation state of the key switch transmitted from the input control unit 12 to the control unit 13 when the key switch is continuously pressed between time T0 and time T29.

  At time T0, pressing of the key switch of the input unit 11 is started, and a key pressing start interrupt is transmitted from the input unit 11 to the control unit 13. In accordance with this interrupt, the control unit 13 starts the operation of the input control unit 12, whereby the input control unit 12 starts the operation (step S12a). Note that when the input control unit 12 is already operating (including the case where the input control unit 12 is paused as described below), the control unit 13 does not start the operation of the input control unit 12 according to the key press start interrupt. .

  The input control unit 12 performs key scanning and stores the received identification information of the key switch that has been pressed and status information “temporary key press” in a predetermined storage unit in the input control unit 12 (step S12b). ). Thereafter, the control unit 13 is requested to restart the operation of the input control unit 12 with a period of 20 ms, that is, every 20 ms, and the operation is paused (step S12c).

  When instructed by the control unit 13 at time T1 = T0 + 20 ms (hereinafter, always T (i + 1) = Ti + 20 ms), the input control unit 12 resumes operation and performs key scan. The identification information received from the input unit 11 by this key scan is compared with the identification information of the key switch that has been pressed at time T0 stored in the input control unit 12 (step S12d).

  At time T1, information indicating that there is no pressed key switch is received, that is, when there is no pressed key switch, the status information stored in a predetermined storage unit in the input control unit 12 is “key”. “Temporary press”, the key switch detected at time T0 is pressed only once, that is, it is determined to be chattering, and information relating to the key switch press is not transmitted to the control unit 13. The operation is terminated (step S12e).

  In step S12d, if the identification information received by the key scan is equal to the identification information of the key switch stored in the predetermined storage unit in the input control unit 12, it is determined that the key switch has been pressed instead of chattering. Then, the identifier of the key switch and that the type of operation status is “short press” are transmitted to the control unit 13 (transmission 21 to the control unit 13 in FIG. 3), and the status information “key” "Short press" is updated and stored in a predetermined storage unit in the input control unit 12, and the operation is paused (step S12f).

  Next, over the time T2 to time T20, the input control unit 12 resumes the operation when instructed by the control unit 13, and each time, the received key switch identification information and storage are performed as in step S12d. The key switch identification information is compared (step S12g).

  When information indicating that there is no pressed key switch is received twice in time, the input control unit 12 determines that the pressing of the key switch has ended, and identifies the identifier of the key switch. Then, the fact that the type of operation status is “released” is transmitted to the control unit 13 (step S12h), and the operation is terminated (step S12i).

  By the operation in step S12h, the control unit 13 recognizes that a normal key switch has been pressed, that is, a short press, within a short time (up to 40 ms) after the end of the press. Thus, processing corresponding to normal pressing can be performed immediately.

  Here, when the information that there is no pressed key switch is received only once, the input control unit 12 updates and stores the status information “temporary key press” in a predetermined storage unit in the input control unit 12, The fact that the type of operation status is “release” is not transmitted to the control unit 13. This is because it is determined that there is a possibility of chattering if the information that there is no pressed key switch is received only once.

  When the status information stored in the predetermined storage unit in the input control unit 12 is “key temporary pressed” and information indicating that there is no pressed key switch is received, the input control unit 12 , It is determined that the key has been pressed, and the above operation is performed.

  Further, the input control unit 12 indicates that the status information stored in the predetermined storage unit in the input control unit 12 is “key temporary press”, and the identification information received by the key scan and the predetermined information in the input control unit 12 When the identification information of the key switch stored in the storage unit is equal, the status information “short key press” is updated and stored in a predetermined storage unit in the input control unit 12. This is the same as described in the explanation of the operation in step S12f.

  In step S12g, over time T2 to time T20, receive information that the received key switch identification information has not been lost twice in succession, that is, no key switch has been pressed twice in succession. If the identification information and the identification information of the key switch stored in the predetermined storage unit of the input control unit 12 are equal ("YES" in step S12g), the input control unit 12 It is determined that the key has been pressed for a long time, and thereafter, the control unit 13 is requested to restart the operation of the input control unit 12 every 100 ms, that is, every 100 ms (step S12j). Is updated and stored in a predetermined storage unit in the input control unit 12.

  The operation of changing the interval at which the operation of the input control unit 12 to resume in step S12j is changed from 20 ms to 100 ms can reduce the power consumption of the information processing apparatus when the key switch is held down.

  Subsequently, the input control unit 12 transmits the identifier of the key switch and that the type of operation status is “long press” to the control unit 13 (transmission 22 to the control unit 13 in FIG. 3), The operation is paused (step S12k).

  Next, every 100 ms (that is, at times T25, T30,...), The input control unit 12 resumes operation when instructed by the control unit 13, and performs a key scan as performed in step S12d. When the received key switch identification information is compared with the stored key switch identification information (step S12m), and information indicating that there is no key switch pressed twice in succession is received, It is determined that the pressing of the key switch has been completed, and the identifier of the key switch and the operation status type “released” are transmitted to the control unit 13 (step S12n, the control unit 13 in FIG. 3). To 23), the operation is terminated (step S12o).

  Here, when the information that there is no pressed key switch is received only once, the input control unit 12 updates and stores the status information “temporary key press” in a predetermined storage unit in the input control unit 12, The fact that the type of operation status is “release” is not transmitted to the control unit 13. This is because it is determined that there is a possibility of chattering if the information that there is no pressed key switch is received only once. When the status information stored in the predetermined storage unit in the input control unit 12 is “key temporary pressed” and information indicating that there is no pressed key switch is received, the key pressing is completed. It is determined that it has been performed, and the above operation is performed.

  Further, the input control unit 12 indicates that the status information stored in the predetermined storage unit in the input control unit 12 is “key temporary press”, and the identification information received by the key scan and the predetermined information in the input control unit 12 When the key switch identification information stored in the storage unit is equal, the status information “key press” is updated and stored in a predetermined storage unit in the input control unit 12. This is the same as described in the explanation of the operation in step S12f.

  In step S12m, the received identification information of the key switch is not missed twice in succession, that is, the information that there is no key switch pressed twice in succession is not received, and the identification information and input When the identification information of the key switch stored in the predetermined storage unit of the control unit 12 is equal (“YES” in step S12m), the input control unit 12 determines that the key switch is being pressed for a long time, Returning to step S12k, the identifier of the key switch and the fact that the type of operation status is “long press” are transmitted to the control unit 13 (transmission 24 to the control unit 13 in FIG. 3) and subsequent operations are repeated. .

  The comparison operation in step S12m is performed every 100 ms. This time interval is larger than the comparison operation in step S12g performed every 20 ms. Therefore, the average time from when the pressing of the key switch is ended to when the input control unit 12 transmits information indicating the end to the control unit 13 is long. Therefore, in order to shorten the time, in the operation of step S12m, when information indicating that there is no key switch pressed once is received, it may be determined that the pressing of the key switch has ended. .

  In step S12d, when the key switch identification information received at time T1 and the key switch identification information stored in the predetermined storage unit in the input control unit 12 are different, the input control unit 12 receives at time T0. The key switch identification information is ignored as chattering information, and the key switch identification information received at time T1 and the status information “temporary key press” are updated and stored in a predetermined storage unit in the input control unit 12. Then, the time T1 is regarded as the time T0, and the subsequent time is regarded in the same manner (that is, the time T (i + 1) is regarded as the time Ti), and the operation is paused. The operations after S12d are performed (not shown).

  In step S12g, if the key switch identification information received at time Tj (2 ≦ j ≦ 20) and the key switch identification information stored in the predetermined storage unit in the input control unit 12 are different, the input The control unit 12 determines that the pressing of the key switch identified by the stored key switch identification information has been completed. Then, it transmits to the control unit 13 the identifier of the key switch and “release” as the type of operation status.

  Further, the input control unit 12 updates and stores the key switch identification information received at time Tj and the status information “temporary key press” in a predetermined storage unit in the input control unit 12. Then, the time Tj is regarded as the time T0, and the subsequent time is regarded in the same manner (that is, the time T (j + k) is regarded as the time Tk), and the operation is paused. The operations after S12d are performed (not shown).

  In step S12m, the key switch identification information received at time Tm (m = 25, 30, 35,...) And the key switch identification information stored in a predetermined storage unit in the input control unit 12 are also displayed. The input control unit 12 determines that the pressing of the key switch identified by the stored key switch identification information has been terminated. Then, it transmits to the control unit 13 the identifier of the key switch and “release” as the type of operation status.

  Further, the input control unit 12 updates and stores the key switch identification information received at time Tm and the status information “temporary key press” in a predetermined storage unit in the input control unit 12. Then, the time Tm is regarded as the time T0, and the subsequent time is also regarded in the same manner (that is, the time T (m + k) is regarded as the time Tk), and the operation is paused. The operations after S12c are performed (not shown). Alternatively, the operation after step S12d may be performed, that is, the same operation may be performed with the restart interval being set to 100 ms.

  The above description includes only the process of ignoring chattering by assuming that the key switch chattering is pressing the key switch that is not continuous in time more than once, or not pressing the key switch. It is not limited to. The key switch chattering may be pressing the key switch only twice or less and not pressing the key switch continuously for three times or not. Further, chattering may not occur.

  Further, the input control unit 12 may be implemented by software. At that time, the operation of the input control unit 12 is performed by a task. That is, the start of the operation of the input control unit 12 is the creation of the task and setting to the active state, the suspension of the operation is the transition to the sleep state of the task, and the restart of the operation is the transition to the active state of the task. The end of the operation corresponds to the transition and the disappearance of the task.

  In the above description, the input unit 11 is an apparatus including one or a plurality of key switches, but the present invention is not limited to this. For example, the apparatus may be provided with a touch panel that is not divided into a plurality of sections or divided into a plurality of sections. Moreover, the apparatus provided with the detection and recognition apparatus of 1 type or multiple types of audio | voice may be sufficient. Moreover, the apparatus provided with the detection and recognition apparatus of 1 type or several types of characters or an image may be sufficient.
