Abstract: The disclosed computer-implemented method for updating locked states may include (i) identifying a computing system and a mobile device that are both operated by a user, (ii) using a signal strength between the computing system and the mobile device to calculate a physical distance between the mobile device and the computing system that correlates to a proximity of the user to the computing system, (iii) calibrating, based on input from a sensor that indicates an activity of the user, a parameter for calculating the physical distance, (iv) using the signal strength and the parameter to recalculate the physical distance, and (v) updating, based at least in part on the recalculated physical distance, a locked state of the computing system in response to a change in the proximity of the user to the computing system. Various other methods, systems, and computer-readable media are also disclosed.
