Contact device for use in controlling a graphical user interface has a multiplicity of connection wires between it and the main unit to permit transfer of different control signals

摘要

Contact device that is connected to a main device (5) has: a contact unit (41) that can generate a contact signal (100) when it is touched; a calculation unit (42) that is electrically connected to the contact unit and which generates a control signal (200) in response to the contact signal; and a transfer interface (43) with a multiplicity of connection wires (201-204) for transfer of different control signals to the main unit. The invention also relates to a contact device for use in controlling a graphical interface, a method for controlling an inventive contact device and an electronic product with an inventive contact device.
