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 vibrate the manipulation surface,
• the drive controlling program causing a computer including a storage part to execute a process, the storage part storing image data for a scrollable image, to be displayed on the display part and including an input field for inputting predetermined information, in association with position data that represents a position of the input field in the image and in association with input data input in the input field, 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;
• determining presence or absence of a deficiency in the input data input in the input field;
• and
• driving the vibrating element by using a driving signal for generating a natural vibration in an ultrasound frequency band at the manipulation surface, based on the operation amount and the operation direction of the scrolling operation that are calculated by the calculating, on the presence or absence of the deficiency that is determined by the determining, and on the position data, to drive the vibrating element according to a first pattern when the input field without the deficiency is being displayed on the display part and to drive the vibrating element according to a second pattern when the input field with the deficiency is not being displayed on the display part.
