Abstract: Embodiments are disclosed that relate to human interface devices having touch sensors. For example, one disclosed embodiment provides a human interface device including a touch sensor comprising two or more touch sensing units, each touch sensing unit comprising a touch sensing pad and a charge accumulation capacitor in communication with the touch sensing pad, the charge accumulation capacitor having a larger capacitance than the touch sensing pad. The human interface device further includes a controller in communication with each touch sensing unit, the controller being configured to acquire a touch sensing sample from each touch sensing unit by iteratively charging the touch sensing pad of the touch sensing unit and transferring charge from the touch sensing pad of the touch sensing unit to the charge accumulation capacitor of the touch sensing unit until a threshold has been met, and detect a touch gesture based upon the touch sensing samples.

Abstract: Embodiments are disclosed that relate to human interface devices configured to enable variable horizontal scrolling. For example, one disclosed embodiment provides a human interface device comprising a horizontal scrolling control, and one or more sensors configured to sense movement of the horizontal scrolling control and provide output that varies depending upon a value of a variable characteristic of the movement. The human interface device further comprises a controller configured to output horizontal scrolling reports having two or more different possible values for each direction of horizontal scrolling based upon the output of the one or more sensors.
