Description

The present invention relates to client devices and server-based computing systems .

  In general, in the SBC system, a key output signal, a mouse output signal, or the like corresponding to a user operation of a client device is transmitted to the server device as an event signal each time the signal is generated. Then, the server device executes an application program corresponding to the event signal from the client device, and transfers the display drawing data generated along with the application program to the client device for display every time the drawing is updated.

  Thus, in the SBC system, every time a user operation is performed on the client device, the event signal is transmitted to the server device. For this reason, in a server apparatus that processes event signals from a large number of client apparatuses, the event processing load increases, and the operation response viewed from the client apparatus decreases.

  As an example of a conventional SBC system, a command is defined for each component of GUI (Graphical User Interface) in communication between a server device and a client device, and represents a property value of the GUI component and a user operation on the GUI component. By communicating a command, it is possible to reduce the amount of communication data and realize a quick GUI response (see, for example, Patent Document 1).

The application ID + command ID of the operation setting data 24a is read and transmitted as an input event signal to the server device 10.

  In this case, the server device 10 determines the command and processing method stored in the display / operation setting database 13b according to the input event signal (application ID + command ID) received from the client device 20, and the corresponding application program Notify (issue) commands to

  Next, the key layout switching control function of the client device 20 according to the operation application in the SBC system having the above configuration will be described.

  FIG. 8 is a flowchart showing a keypad control manager process (13a) by the server device 10 of the SBC system.

  The keypad control manager process (13a) by the server apparatus 10 executes the process described below every time it is determined that a certain time (for example, 1 sec) has passed at a relatively short interval (step S1).

  That is, when the elapse of the predetermined time is determined during the operation of the application program according to the input event signal from the client device 20 in the server device 10 (step S1), the type of the application program currently being operated is detected. The presence or absence of the change is determined (step S2).

  If it is determined that the type of the application program currently being operated has been changed, the display / operation setting database 13b in which display / operation setting data corresponding to the changed application program is stored in the ROM 13 in advance. It is determined whether it is registered in (see FIG. 6) (step S3).

  For example, when a Web browser program is started in response to an input event signal from the client device 20, display / operation setting data corresponding to the Web browser program is registered in the display / operation setting database 13b (see FIG. 6). If it is determined (step S3 (with registration)), the application ID “1” corresponding to the application name “browser” activated this time from the display / operation setting database 13b, the command ID “ 1 ”to“ 7 ”, key display positions“ left 1 ”to“ right 4 ”, and key display contents“ new creation ”to“ end ”are read (step S4), and the client as keypad control information. It is transmitted to the device 20 (step S5).

  Further, in the step S3, for example, when any application program corresponding to an input event signal from the client device 20 is activated, display / operation setting data corresponding to the application program is displayed in the display / operation setting database 13b ( If it is determined that it is not registered (see step S3 (no registration)), keypad control information without registration is transmitted to the client device 20 (step S5).

  Thus, according to the processing of steps S2 to S5, keypad control information corresponding to the change of the application program is transmitted to the client device 20, or the type of the application program currently being operated is not changed in step S2. If it is determined, whether or not an input event signal is received according to the user operation from the client device 20 is repeatedly determined (step S6).

  Here, if it is determined that an input event signal has been received from the client device 20 in response to a user operation, a processing method according to the content of the input event signal is selected from the display / operation setting database 13b (FIG. 6) (step S7), and the corresponding process is executed (step S8).

  Specifically, for example, the currently operating application program is a Web browser program, and the Web browser command key KB displayed on the input device (soft keyboard) 27 of the client device 20 (see FIG. 7B). ) Is received from the display / operation setting database 13b (see FIG. 6), when an input event signal (application ID “2” + command ID “4”) according to the user operation of the “home” key is received. A processing method (key issue (Alt + Home)) corresponding to the content of the input event signal (application ID “2” + command ID “4”) is acquired (step S7), and the corresponding key signal (Alt + Home) is obtained. A corresponding process issued to the Web browser program in operation is executed (step S8).

  In this case, the screen data G of the homepage of a URL address set in advance for the client device 20 is acquired, drawn and expanded in the client frame buffer RAM 14a, and transmitted to the client device 20 as screen update information.

  FIG. 9 is a flowchart showing a reception process by the client device 20 of the SBC system.

  Connected to the server device 10 by a login request to the server device 10 when the client device 20 is turned on (step R1), and in the standby state for reception from the server device 10 (step R2), some signal is received. Then, it is determined whether the type of the received signal is keypad control information or screen update information (step R3).

  Here, when it is determined that the signal received from the server device 10 is keypad control information associated with a change in the running application program, the keypad control information corresponds to the running application name. Then, it is determined whether it is necessary keypad control information consisting of a pre-registered application ID, command ID, key display position, and key display contents, or unnecessary keypad control information without registration (step). R4).

  Here, the keypad control information received from the server device 10 includes, for example, an application ID “1”, command IDs “1” to “7” corresponding to the application name “browser” activated this time, and a key display. When the keypad control information is determined to be necessary keypad control information composed of data of positions “left 1” to “right 4” and key display contents “new creation” to “end”, the keypad control information is displayed. The operation setting data 24a is stored in the RAM 24, and the keypad control flag 24b is set to On (step R5).

  Then, according to the key display positions “left 1” to “right 4” and the key display contents “new creation” to “end” of the display / operation setting data 24a stored in the RAM 24, the input device (soft keyboard) 27 The key arrangement pattern of the switchable key display area 27a is switched to the Web browser command key KB and displayed as shown in FIG. 7B (step R6).

  If it is determined that the keypad control information received from the server device 10 is unnecessary keypad control information without registration, the keypad control flag 24b is set to Off and the input device (software) The key arrangement pattern of the switchable key display area 27a in the (keyboard) 27 is switched to the Kana input key Km set for initial display as shown in FIG. 4B, for example (step). R7).

  On the other hand, when it is determined in step R3 that the signal received from the server device 10 is the screen update information, the updated screen data G is drawn and expanded in the frame buffer RAM 25 and is displayed on the display device 26. It is displayed (step R8).

  FIG. 10 is a flowchart showing transmission processing by the client device 20 of the SBC system.

  When it is determined in the client device 20 that an input operation has been performed in accordance with a user operation of the input device (soft keyboard) 27 (step T1), the keypad control flag 24b in the RAM 24 is currently set to either On / Off. Is determined (step T2).

  Here, the keypad control flag 24b in the RAM 24 is currently set to On, that is, the key arrangement pattern in the current input device (soft keyboard) 27 is displayed according to the change of the application program in the server device 10. When it is determined that it is displayed based on the operation setting data 24a (step T2 (On)), it is stored in the RAM 24 in accordance with the key position input by the input device (soft keyboard) 27. The application ID and command ID are read from the display / operation setting data 24a (application ID / command ID / key display position / key display content) (step T3) and transmitted to the server device 10 as an input event signal (step S3). T4).

  On the other hand, the keypad control flag 24b in the RAM 24 is currently set to Off, that is, the key arrangement pattern in the current input device (soft keyboard) 27 is dedicated to the application program in operation in the server device 10. If it is determined that a normal key layout pattern (see FIG. 4) defaulted by the client device 20 is displayed, which is not a key layout (step T2 (Off)), the input device (soft keyboard) ) The key input signal input and operated at 27 is transmitted as it is to the server device 10 as an input event signal (step T5).

  Therefore, according to the key arrangement switching control function of the client device 20 corresponding to the operation application in the SBC system having the above-described configuration, the input device (soft keyboard) of the client device 20 according to the type of the application program operating on the server device 10. 27, a display / operation setting database 13b in which an application ID, a command ID, a key display position, and key display contents for defining a key arrangement pattern in association with each other is stored in the ROM 13 of the server device 10 in advance. When an application program that operates on the server device 10 is changed in response to an input event from the client device 20, the key layout pattern definition information corresponding to the operation application is read from the display / operation setting database 13b. It transmits to the client device 20. Then, the key arrangement pattern displayed on the input device (soft keyboard) 27 of the client device 20 is switched to the key arrangement pattern corresponding to the operation application in accordance with the definition information received from the server device 10 and displayed. A key signal (application ID + command ID) corresponding to a user operation based on the key arrangement pattern is transmitted to the server device 10 to instruct processing of the operation application.

  As described above, when the input device (soft keyboard) 27 of the client device 20 in the SBC system is operated, for example, when a Web browser program is operated, the text creation program is operated such as “favorite”, “return”, and “forward” In this case, a small client device 20 such as a portable terminal can be used by switching frequently used commands such as “new creation”, “save”, and “redo” to a key arrangement pattern that allows direct key input.
