Abstract: A method may include receiving an input signal from a force sensor configured to sense a force associated with a human interaction with a virtual button, comparing the input signal to at least one behavioral model, the at least one behavioral model comprising one or more parameters associated with a valid human interaction with the virtual button, and determining whether a valid human interaction with the virtual button occurred based on the comparing.

Abstract: A system may include a resistive-inductive-capacitive sensor, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and configured to at a plurality of periodic intervals, measure phase information associated with the resistive-inductive-capacitive sensor and based on the phase information, determine a displacement of a mechanical member relative to the resistive-inductive-capacitive sensor. The system may also include a driver configured to drive the resistive-inductive-capacitive sensor at a driving frequency and a driving amplitude, wherein at least one of the driving frequency and the driving amplitude varies among the plurality of periodic intervals.
