<p>PURPOSE:To surely execute input operation by informing a key to be touched with a finger or the like by sound, light ON/OFF, color inversion, etc., immediately before the finger or the like touches a touch panel. CONSTITUTION:When a finger or the like is detected by detecting parts 3, 5 for detecting a finger or the like immediately before contacting with the touch panel 2, the finger detection is informed to a control part 8 and the control part 8 informs the contents of an instruction pointed out by the finger or the like by sound from a speaker 4. After checking whether an input instruction is correctly executed or not by the sound from the speaker 4, an operator touches the touch panel 2 with the finger or the like to inform the execution of the input instruction through sound. For instance, sound such as a click sound is generated by the control part 8 through the speaker 4 and a CRT control part 7 is commanded to display the succeeding input instruction on a CRT 9. Consequently, input operation can be surely executed.</p> |
