Input device and input method
A contact unit includes a plurality of areas capable of exciting a surface of a touch panel individually. A control unit controls a state of the plurality of areas individually based on a pre-stored excitation pattern when a user control unit is used. The excitation pattern describes a state transition pattern of the plurality of areas corresponding to a track of a multi-touch gesture such as a pinch-out gesture and a pinch-in gesture.
1. An input device comprising:
a contact unit including a plurality of areas that excites a surface of a touch panel independently;
a user control unit used by a user;
a control unit that controls a state of the plurality of areas individually based on a pre-stored excitation pattern that describes a state transition pattern of the plurality of areas corresponding to a track of a multi-touch gesture when the user control unit is used; and
an imaging unit that captures an image of a display unit of a device that includes the touch panel that the contact unit comes into contact with,
wherein the control unit analyzes the image of the touch panel captured during or after a series of steps of control in the plurality of areas based on the pre-stored excitation pattern, and
wherein when a process based on user control is determined to not be executed on the surface of the touch panel, the control unit performs a series of steps of control in the plurality of areas based on the pre-stored excitation pattern with a different sensitivity.
2. The input device according to claim 1 ,
wherein the control unit controls a first area of the plurality of areas that excites the surface of the touch panel to be in a conductive state, and
wherein the control unit controls a second area of the plurality of areas that does not excite the surface of the touch panel to be in an insulated state.
3. An input method using an input device provided with a contact unit and a user control unit, comprising:
acknowledging user control by a user in the user control unit;
individually controlling, in response to the user control by the user, a state of a plurality of areas formed in the contact unit and capable of exciting a surface of a touch panel independently, based on a pre-stored excitation pattern, that describes a state transition pattern of the plurality of areas corresponding to a track of a multi-touch gesture; and
capturing an image of a display unit of a device that includes the touch panel that the contact unit comes into contact with,
wherein the individually controlling analyzes the image of the touch panel captured during or after a series of steps of control in the plurality of areas based on the pre-stored excitation pattern, and
wherein when a process based on the user control is determined to not be executed on the surface of the touch panel, the control unit performs a series of steps of control in the plurality of areas based on the pre-stored excitation pattern with a different sensitivity.
