1. A display system comprising:
a head-mounted display unit configured to provide content while a user perceives a real environment, the head-mounted display unit being operable in a low-power state and a high-power state; and
a wake control system for determining when to operate the head-mounted display unit in the high-power state, the wake control system configured to:
in the low-power state,
assess an initial wake criterion with a first sensor of the head-mounted display unit, wherein the initial wake criterion is associated with an environmental stimulus and indicative of available content in the real environment,
provide a virtual stimulus that indicates the availability of the content in the high-power state with the head-mounted display unit in response to satisfaction of the initial wake criterion, and
assess a user response criterion corresponding to the virtual stimulus with a second sensor of the head-mounted display unit, wherein the user response criterion is associated with a user behavior, and
in the high-power state, operate the head-mounted display unit to provide the content based upon satisfaction of the user response criterion.
