Abstract: Various embodiments of systems, apparatus, and methods are described for A user input device, such as a remote control device. In one implementation, the remote control device includes at least one pair of electrical contacts, at least one button configured to electrically connect the at least one pair of electrical contacts, and a degradation measurement module in electrical communication with at least one of the electrical contacts. The degradation measurement module is configured to determine a degradation level of the at least one button based on at least one electrical property of a circuit associated with the at least one button when the at least button electrically connects the at least one pair of electrical contacts.
