A system may include a resistive-inductive-capacitive sensor, a measurement circuit communicatively coupled to the resistive-inductive-capacitive sensor, and a filter communicatively coupled to the measurement circuit. The measurement circuit may be configured to 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 filter may be configured to isolate changes to the displacement which are significantly slower than an expected change to the displacement in response to a human interaction with the mechanical member. 一种系统可以包括：电阻-电感-电容式传感器，通信地耦合到所述电阻-电感-电容式传感器的测量电路，以及通信地耦合到所述测量电路的滤波器。测量电路可以被配置为测量与电阻-电感-电容式传感器相关联的相位信息，并且基于该相位信息，确定机械构件相对于电阻-电感-电容式传感器的位移。滤波器可被配置为隔离位移变化，该位移变化明显比响应于人与机械构件的交互的预期位移变化慢。
