<p><P>PROBLEM TO BE SOLVED: To provide an operation input device capable of preventing erroneous operation. <P>SOLUTION: When an operation area 52A of a touch panel facing an operation key 55 displayed on a display screen 51C is operated and its positional information is output from the touch panel, the operation key 55 corresponding to the positional information is not selected but only notified on the display screen 51C (the figure 4 (a)) until a predetermined period of time is measured. Subsequently, when the predetermined period of time is measured, the operation key 55 corresponding to the positional information outputted continuously is selected (the figure 4 (b)). A user can select the operation key 55 by performing operation in any position inside the operation area 52A and continuing the operation after confirming notification of the operation key 55 corresponding to the positional information before the predetermined period of time is measured, thereby preventing erroneous operation. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
