Abstract
A software defined button includes a force sensor and a haptic output element. The button further includes an immutable logic core and a mutable logic core. The mutable logic core is configured to define one or more thresholds against which input received from the force sensor can be compared to determine whether a user input has been provided. The immutable logic core is configured to verify actual force input has been received when the mutable logic core signals that user input has been received. In response to receiving a verified force input, the haptic output element can be caused to be driven by one of the mutable or immutable logic cores to provide a haptic output to a user.
