Hand sensing controller
First Claim
1. A touch-sensitive controller, comprising:
- controller body supporting a thumb-centric portion, and a trigger-centric portion;
first sensor pattern associated with the thumb-centric portion, the first sensor pattern comprising a first plurality of conductors and a second plurality of conductors, the first and second plurality of conductors oriented such that a touch event proximate to the thumb-centric portion will cause a change in coupling between at least one of the plurality of first conductors and at least one of the plurality of second conductors;
second sensor pattern associated with the trigger-centric portion, the second sensor pattern comprising a third plurality of conductors and a fourth plurality of conductors, the third and fourth plurality of conductors oriented such that a touch event proximate to the trigger-centric portion will cause a change in coupling between at least one of the plurality of third conductors and at least one of the plurality of fourth conductors;
signal generator operatively connected to separate ones of each of the conductors in the first and third pluralities of conductors, the signal generator emitting a frequency orthogonal signal on each of the separate ones of each of the first and third pluralities of conductors;
plurality of signal receivers, each of the plurality of signal receivers operatively connected to separate ones of the conductors of each of the second and fourth plurality of conductors, each of the plurality of signal receivers being adapted to receive signals present on the conductor to which it is operatively connected, the plurality of signal receivers being adapted to receive a frame during an integration period by simultaneously receiving signals present on the separate ones of the conductors to which it is operatively connected;
signal processor adapted to generate a first heatmap reflecting electromagnetic disturbance proximate to the thumb-centric portion and a second heatmap reflecting electromagnetic disturbance proximate to the trigger-centric portion, each heatmap based, at least in part, on a frame received during an integration period.

Abstract
Disclosed is a touch-sensitive controller system employing a controller comprising a plurality of separate FMT sensor patterns adapted to detect a variety positions of the human hand. The controller system outputs both touch events as well as data reflective of the hand interaction with the controller. The FMT sensors may be driven by a common signal generator, and can look at body-generate crosstalk to aid in understanding the position, orientation and grip of a hand on the controller. In an embodiment, signal injection can supplement FMT sensor data. Fusion among the data transmitted and received by the plurality of FMT sensors and additional injected signals may provide improved fidelity in both touch and hand modeling.
