Latency and preemptive detection for an input device

Abstract:

Some embodiments related to an input device with a hybrid switch coupled to a depressible element. The hybrid switch can include a first and second switch with both switches configured to activate in response to a depressible element being pressed by a user. In some aspects, the hybrid switch architecture can be used to introduce an interrupt signal when the depressible element is pressed by a threshold distance (thereby generating event data) to ensure that a periodic input device report includes the event data regardless of when a periodic switch status check is performed. In further embodiments, the hybrid switch architecture can be used to calibrate the input device and set a reliable preemptive activation threshold that cause the input device to generate event data.
