This invention addresses the problem of providing a drive control apparatus, an electronic device, and a drive control method that, by providing good tactile feedback, make it easy for a user to discern the direction of a location where a touch operation is supposed to be inputted. This drive control apparatus drives a first vibrating element in an electronic device that has a display panel, a touch panel provided on the display-surface side of said display panel, and the aforementioned first vibrating element, which vibrates a touch-operation surface via which touch operations are inputted to the touch panel. Said drive control apparatus has a first drive control unit that drives the first vibrating element using a drive signal that produces ultrasonic resonance in the touch-operation surface. Said first drive control unit drives the first vibrating element so as to change the intensity of the ultrasonic resonance in accordance with the relationship between the location of a prescribed GUI widget displayed on the display panel and the location of touch-operation input to the touch-operation surface. |
