Abstract
A spherical input devicefor navigating a virtual environmentis activated for touch sensitivity at any point on its surfaceby a capacitive touch sensorthat includes first and second capacitance-sensing elementsand. A first variable capacitanceis formed between a first capacitance-sensing element and a first area of the user's hands through a first hemisphere. A second variable capacitanceis formed between a second capacitance-sensing element and a second area of the user's hands through the second hemisphere. A touch-responsive capacitanceincludes the first variable capacitance in series with the second variable capacitance. Gestural data is derived from the touch-responsive capacitance and device rotations, and transmitted in gestural radio signalsto a receiver. One or both of the capacitance-sensing elements is configured to minimize attenuation of the gestural radio signals passing through the surface.
