Abstract:
1. A data processing device including a display unit configured to display an image including an identification image identifying data to be processed in an image display area on a display screen and an input unit configured to receive an instruction input indicating a position on the display screen, comprising: an acquisition unit configured to acquire position information indicating a position of an instruction input received by the input unit; a recognition unit configured to specify an enclosed region in the image display area based on a trajectory indicated by a set of position information acquired by the acquisition unit according to sequential instruction inputs through the input unit, and when an identification image identifying data to be processed is included in the enclosed region, recognize the identification image as a selected identification image and recognize a direction the selected identification image is enclosed by the trajectory of the set of position information as a direction of selection; a determination unit configured to determine processing to be executed on the data to be processed in accordance with the direction of selection recognized by the recognition unit; and an execution unit configured to execute the processing determined by the determination unit on the data to be processed, wherein the identification image is a representative image representing the data to be processed on the display and is different from the data to be processed itself, the recognition unit recognizes which of a first direction and a second direction opposite to the first direction the direction of selection is, the determination unit determines to execute first processing on the data to be processed when the selected identification image is enclosed in the first direction by the trajectory of the set of position information and execute second processing different from the first processing on the data to be processed when the selected identification image is enclosed in the second direction by the trajectory of the set of position information, the first processing is processing of changing the data to be processed from a first state to a second state, the second processing is processing of changing the data to be processed from the second state to the first state, and the display unit is further configured to display, on a part of the display screen, a result of the executed processing.
