Abstract
In some embodiments, a computer mouse includes a housing, a depressible keyplate, and a haptic element coupled to a bottom surface of the depressible keyplate. The haptic element can be configured to operate in a plurality of modes of operation including a first mode and a second mode. In the first mode of operation, the haptic element can generate a haptic output that statically and unidirectionally deflects and holds the haptic element and coupled keyplate at a deflection distance. In the second mode of operation, the haptic element can generate a second haptic output that bidirectionally deflects the haptic element relative to the deflection distance thereby generating a vibrational feedback that is superimposed on the unidirectional deflection at the deflection distance. In some aspects, the haptic element is a piezoelectric device and the control signal is a voltage applied to the haptic element.
