Abstract

A display system includes a head-mounted display unit and a wake control system. The head-mounted display unit provides content to a user and is operable in a low-power state and a high-power state that consumes more power to provide the content to the user than the low-power state. The wake control system determines when to operate in the high-power state. The wake control system may assess a first wake criterion with low power, assess a second wake criterion with higher power than the first wake criterion upon satisfaction of the first wake criterion, and cause the head-mounted display unit to operate in the high-power state upon satisfaction of the second wake criterion.
