Abstract
Systems and methods for track-pad input are disclosed. In one embodiment, a track-pad device includes a center sensor and a plurality of radial sensors. The center sensor senses electrical characteristic change at a center of the track-pad device. The plurality of radial sensors sense electrical characteristic changes in the respective vicinity of each of the plurality of radial sensors. The plurality of radial sensors can be configured in concentric rings about the center sensor.
