1. A method comprising:
- transmitting an actuator signal to an actuator coupled to a touch surface of a device, the actuator signal configured to cause the actuator to output a force to the touch surface;
receiving a response of the touch surface to the force;
determining a resonant frequency of the touch surface based at least in part on the response, wherein the resonant frequency of the touch surface is based in part on user interaction with the touch surface; and
outputting a signal indicative of the resonant frequency.

Abstract
Systems and methods for resonance detection are disclosed. For example, one method for resonance detection includes the step of transmitting an actuator signal to an actuator coupled to a surface of a device. The actuator signal is configured to cause the actuator to output a force to the surface. The method further includes the steps of receiving a response of the surface to the force; determining a resonant frequency of the surface based at least in part on the response; and outputting a signal indicative of the resonant frequency.
