It is a summary.
Such a processing method includes an event handler step of updating the display of a character string in response to reception of an event after receiving a key input signal as an event. On the other hand, there is a separation step for releasing a part of the processing of the event handler step as processing that is separated from the event.

  That is, according to the processing method described above, when executing the process of updating the display of the character string, at least a part of the process is taken out as a process separated from the event. For this reason, the response time to the user can be shortened and the display of the character string can be updated by an amount corresponding to the amount of processing that has gone out.

  Therefore, it is possible to provide a processing method that can shorten the apparent response time to the user's input even when the specifications of the personal computer are low.

  The second feature of the present invention relates to the first feature of the present invention, and the gist thereof is that the process separated by the separation step includes a process of decorating the character string.

  The input character confirmation button 113 is a button for confirming the unconfirmed character 131. Specifically, the input character confirmation button 113 confirms the unconfirmed character 131 by receiving a signal indicating that the input character confirmation button 113 has been selected from the remote control device 50 based on a user operation. For example, the unconfirmed character 131 displayed as “Minatoku” in the input character display frame 111 is converted to “Minato Ward”, and then the input character confirmation button 113 is selected, whereby the confirmed character string 133 and Become.

  A confirmed character string 133 that is a character string displayed as the confirmed unconfirmed character 131 is output by the output unit 33. Specifically, when the input character confirmation button 113 is selected, the confirmed character string 133 is output to the search form 130.

  The key button 119 is a button corresponding to a key assigned to the remote control device 50. Specifically, kana, roman letters, symbols, and the like are assigned to each numeral so as to correspond to the numeric keys 1 to 12 of the remote control device 50. The key button 119 changes the background color based on a signal from the remote control device 50. For example, when the user presses the “6” key button of the remote control device 50, the event handler 19 changes the background color of the “6” key button 119.

  For example, in the key button 119 shown in FIG. 3, “A”, “KA”, and “SA” are assigned to the numeric keys 1 to 3. In this case, the user has selected “KA” by pressing the 2 button of the remote control device 50. Subsequently, in the key button 119, “ka”, “ki”, “ku”, “ke”, and “ko” are assigned to the numeric keys 1 to 5. Thereby, the user can select the character which he selected. The key buttons 119 are assigned to Roman letters, symbols, and the like in the same manner, and thus detailed description thereof is omitted.

  The key button 119 is updated by the software keyboard display unit 31 based on a signal received from the remote control device 50.

  The search candidate display frame 121 displays a conversion candidate 135 corresponding to the unconfirmed character 131 via the communication network. The search candidate display frame 121 may extract the conversion candidate 135 corresponding to the unconfirmed character 131 from the storage unit 17 and display it. For example, when “Minatoku” is displayed as the undetermined character 131 in the input character display frame 111, “Minato-ku”, “Minato-ku Akasaka”, “Minato” are displayed in the search candidate display frame 121 as conversion candidates 135. “Akasaka 9-chome” is displayed.

  The search form 130 displays the confirmed character string 133 output by the output unit 33. When an adjacent search button is selected, the search form 130 acquires corresponding page data using the confirmed character string 133 as a search query via the communication network.

(6) Action / Effect As described above, according to the present embodiment, the processing method executes event handler processing in response to the reception of the event in step S130, and the undefined character 131 is displayed in the input character display frame 111. Is displayed, and step S190 is taken out as a process in which a part of the process of the event handler step is separated from the event. That is, according to the processing method, a part of the process for displaying the undetermined character 131 is separated, so that the processing time until the undetermined character 131 is displayed can be shortened. Accordingly, even when the specs of the personal computer are low, the apparent response time to the user input can be shortened.

  In the embodiment, the process separated in step S190 is a process for decorating a character string. That is, the process separated in step S190 is a process that does not hinder the user's operation even if it is not immediately reflected. Therefore, according to the processing method, it is possible to reliably reduce the apparent response time to the user input.

  In the embodiment, the process separated in step S190 is executed by a timer process. For this reason, the separated process is executed at a timing different from that in step S <b> 170 in which the undetermined character 131 is displayed in the input character display frame 111. Therefore, since it is possible to suppress the concentration of the processing of the personal computer, it is possible to shorten the processing time related to the processing executed in step S170 even when the specification of the personal computer is low.

  In the embodiment, the process separated in step S190 is a process of updating the entire display of the software keyboard 110. That is, the process separated in step S190 is a process that does not hinder the user's operation even if it is not immediately reflected.
