FIELD: physics.
SUBSTANCE: device has a touch detecting unit configured to detect a touch operation and an adjustment operation for a display unit, a timing unit configured to measure the period of time of continuous touch in a specific area of the display unit, and a control unit configured, upon detection of an adjustment operation from a specific area and when the measured time period of continuous touch has not reached a predefined time period, to perform a function assigned to the specific area, and upon detection of an adjustment operation from a specific area and when the measured time period for continuous touch reaches a predefined time period, is configured to perform a function assigned for the specific area relative only the detected adjustment operation.
EFFECT: high reliability of mitigating operational errors on an area of a touch panel where there is probability of unintentional continuous touching.
