Abstract

A data processing device includes an acquisition unit that, when, upon sequential instruction inputs by a user, an operation of enclosing an object displayed on a display screen with a trajectory of position information indicated by the instruction inputs is performed, acquires position information representing positions indicated by those instruction inputs, a recognition unit that recognizes the object as a selected object and further recognizes the direction of selection in which the selected object is enclosed, a determination unit that determines processing in accordance with the direction of selection, and an execution unit that executes the determined processing on the selected object. Processing desired by a user can be thereby made by simple instruction inputs such as selection of the direction of enclosing an object with a trajectory of a set of position information, and the selected processing can be executed on the selected object.
