Drive controlling apparatus, electronic device, computer-readable recording medium, and drive controlling method

A computer-readable recording medium having stored therein a drive controlling program for driving a vibrating element of an electronic device, the electronic device including a display part;

• a top panel disposed on a display surface side of the display part and having a manipulation surface;
• a coordinate detector configured to detect coordinates of a manipulation input performed on the manipulation surface;
• and the vibrating element, which is configured to generate a vibration at the manipulation surface,
• the drive controlling program causing a computer including a data storage part to execute a process, the data storage part storing image data for a scrollable image, to be displayed on the display part, in association with edge position data that represents a position of an edge of the image, or with direction data that represents a scrollable direction of the image, the process comprising:
• calculating, based on the coordinates detected by the coordinate detector, an operation amount and an operation direction of a scrolling operation performed on the manipulation surface;
• and
• driving, upon the scrolling operation being performed on the top panel, the vibrating element by using a driving signal for generating a natural vibration in an ultrasound frequency band at the manipulation surface, to drive, based on the operation amount and the operation direction of the scrolling operation and based on the edge position data, the vibrating element according to a first pattern when the edge is not being displayed on the display part, and drive the vibrating element according to a second pattern when the edge is being displayed on the display part, or to drive, based on the operation amount and the operation direction of the scrolling operation and based on the direction data, the vibrating element according to a third pattern when the direction of the scrolling operation is the scrollable direction and drive the vibrating element according to a fourth pattern when the direction of the scrolling operation is not the scrollable direction.
