Abstract: An information processing device includes a touch panel display that displays an object, a contact state detection unit that detects a state of proximity or contact of a finger on the touch panel display, a coordinate detection unit that detects proximity position coordinates on a plane of the touch panel display when the state of proximity of the finger on the touch panel display is detected by the contact state detection unit, and an object selection unit that calculates a direction of movement and a speed of movement of the proximity position coordinates in a plane direction of the touch panel display based on the proximity position coordinates and selects the object displayed at a position corresponding to the direction of movement and the speed of movement.

Abstract: A terminal device to accurately define a selection range by an intuitive operation when an object is selected on a touch panel display. The terminal device includes a touch panel display for displaying an object and sensing proximity or contact of a finger, a coordinate sensing unit for detecting a coordinate value of an approaching position or a contacting position of the finger to the touch panel display, and an object selecting unit. The object selecting unit sets a selection range defined by the coordinate values of the plurality of fingers and selects the object included in the selection range when the coordinate values of the plurality of fingers detected by the coordinate sensing unit have been concurrently maintained for a predetermined time.

Abstract: A mobile terminal device 1 includes a touch panel display that displays an image and receives an input operation of information by a user's finger, an operation lock control unit that controls stop of the display of an image and the receipt of an input operation on the touch panel display, and a coordinates and distance detection unit that detects proximity coordinates of the finger to the touch panel display and a level of a proximity distance in the proximity coordinates, and the operation lock control unit performs control to release the stop when a combination of the proximity coordinates and the level of the proximity distance is approximate to prestored pattern information.
