Abstract
Systems and methods incorporating an embedded sensor in a control stick to detect the presence of an object, such as a thumb. A presence detect signal may be generated by the additional sensor and auto calibration logic then may automatically remove bias from the control stick in real time when the presence detect signal indicates the control stick is not under the influence of a force external to the controller, and therefore at its neutral mechanical position. In further embodiments, embedded sensors are arrayed across an exterior surface of a control stick as a secondary control stick-based positional input device. In such embodiments, tactile or proximity sensor technology may be applied to either improve precision of first positional information generated by the control stick or to control a coordinate space separate from that controlled by first position information provided by the control stick.
