  • Patent number: 10969958
    Abstract: Provided is a technique for supporting communication of a method for using an application for a key-input display apparatus that displays a key input on the application on an execution screen of the application displayed on a display unit. The key-input display apparatus includes an input-history display control unit that outputs an input-history display screen to the display unit. The input-history display screen sequentially displays key operation histories of key inputs one by one as a separate screen from the execution screen of the application. Thus, key inputs for the application are visualized, and therefore there is no need to alternately follow an input operation with an input device, such as a keyboard, and the execution screen of the application with eyes, allowing easy grasp of key inputs by watching the input-history display screen displayed side by side with the execution screen of the application.
