1. A method for determining a temperature-compensated touch state of a device, the method comprising:
receiving, by a processor of the device and from a first sensor of the device, a first measured value corresponding to a first sensor measurement captured by the first sensor;
receiving, by the processor and from a temperature sensor of the device, a temperature value corresponding to a first temperature measurement associated with the device and captured by the temperature sensor;
adjusting a signal corresponding to the first sensor measurement based upon, at least in part, the temperature value, to create a temperature-compensated touch signal;
determining, by the processor, the temperature-compensated touch state of the device based upon, at least in part, the temperature-compensated touch signal;
determining, by the processor, that the temperature-compensated touch signal is representative of a touched state of the device based upon, at least in part, the temperature-compensated touch signal minus a baseline delta being above a touched threshold;
indicating that the device has been touched; and
unlocking the device after a single touch based upon, at least in part, the indicating that the device has been touched.
