ABSTRACT:
A family of controllers incorporate multiple force/touch sensitive input elements to provide intuitive input in up to six degrees of freedom, including position and rotation, in either a Cartesian, cylindrical or spherical coordinate system. Six dimensions of input can be generated without requiring movement of the controller, which provides a controller suitable for controlling cursors and display objects in an interactive computer system and for equipment such as heavy cranes and fork lift trucks. Positional information is obtained either by use of a "pushing" or "dragging" metaphor. Rotational information is provided by either a "pushing," "twisting," or "gesture" metaphor. In certain embodiments, the same sensor is used for both positional and rotational inputs, and the two are differentiated by the magnitude of the force applied to the sensor.
