Abstract: A data processing device includes a processor that executes a procedure. The procedure includes: (a) detecting contact with an operation face and outputting contact position data expressing a contact position at the operation face; (b) predicting a contact operation based on a number of contact positions identified based on the contact position data output at (a) prior to the contact operation to the operation face being identified based on a time series of the contact positions expressed by the contact position data output at (a); and (c) executing processing according to the contact operation predicted at (b).

Abstract: According to one aspect of the invention, there is provided a mobile apparatus including: a display; an input module; a timer configured to output a first signal representing that a first time elapses since the input module is last operated, and to output a second signal representing that a second time elapses since the input module is last operated, the first time being different from the second time; a display control module configured to disable a display on the display when the first signal is received; and an input control module configured to disable an input at the input module when the second signal is received.
