发明名称 Touch panel input apparatus
摘要 A touch panel input apparatus comprises a memory storing data for correcting a key position according to the distance between a touch panel and a cathode ray tube (CRT) display and also according to the surface shape of the display screen. In response to the application of a touch input, a key code corresponding to display information is read out from the memory to display an effective key input area. The key position correction data is determined depending on an enlarged effective range of the touch key input and also depending on the parallax of the user viewing the display screen.
