Abstract: A system may include a tactile actuator for providing tactile feedback and a resonant phase sensing system. The resonant phase sensing system may include a resistive-inductive-capacitive sensor and a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor and the tactile actuator. The resistive-inductive-capacitive sensor may be configured to measure phase information associated with the resistive-inductive-capacitive sensor, based on the phase information, detect an indication of human interaction with the system proximate to the resistive-inductive-capacitive sensor, and trigger the tactile actuator to generate tactile feedback responsive to detecting the indication of human interaction.
