Abstract:
A method for providing signals from a computer input device having a ball adapted to be rotationally manipulated by a user in a user vector space to a host PC, said method comprising:providing a microcontroller coupled to a sensor positioned at a first location parallel to a plane tangent to the ball, the sensor disposed in a sensor vector space; detecting rotational movement of the ball by the sensor and producing a detected vector motion report correlating to the rotational position of the ball; converting the detected vector report into a reported vector report which simulates a detected vector report that would be produced by a sensor positioned at a second location parallel to another plane tangent to the ball, the reported vector report disposed in a reported vector space; and processing the reported vector report into input signals to the host PC to correlate movement of the ball to movement of an on-screen cursor.
