Abstract
Disclosed are computer peripheral interface devices (such as computer mice) that include a wheel member configured to rotate around an axis in a plurality of modes, where each of the plurality of modes corresponds to a respective unique friction profile. The plurality of operation modes includes a freewheel mode and at least two additional modes. The at least two additional modes includes two or more different ratchet modes, two or more different constant friction modes, or at least one constant friction mode and at least one ratchet mode. The interface device also includes an actuator assembly configured to set the wheel member to each of the plurality of operation modes.
