Patent ID: 7651442

Claim:
A system comprising: a user interface to engage a portion of a user's body, the user interface configured to move in three dimensional space; a resistance system coupled to the user interface, the resistance system to provide a user selectable resistance to movement of the user interface; a lead coupled to the user interface and the resistance system, wherein the lead, in tension, to convey a user force from the user interface to the resistance system; at least one sensor component located proximate to the user interface to detect at least one change occurring at the user interface, the at least change resulting from user input to the user interface, the at least one sensor component to assist in creating an output signal representative of the at least one change, the at least one sensor component to move with the user interface in three dimensional space and a processing system to receive the sensor output over a time interval, to process the sensor output and to transmit the processed sensor data over a network.
