1. A head-mounted display system configured to project light to an eye of a user to display augmented reality image content in a vision field of said user, said head-mounted display system comprising:
a frame configured to be supported on a head of the user in an upright position;
a head-mounted display disposed on the frame, said display configured to project light into said user's eye to display augmented reality image content to the user's vision field, at least a portion of said display being transparent and disposed at a location in front of the user's eye when the user wears the frame in the upright position such that said transparent portion transmits light from a portion of the environment in front of the user and said head-mounted display to the user's eye to provide a view of said portion of the environment in front of the user and said head-mounted display;
one or more sensors comprising an inward-facing imaging system and/or an outward-facing imaging system; and
processing electronics in communication with the display and the one or more sensors, the processing electronics configured to:
receive a signal from the one or more sensors;
determine whether the frame is on top of the head of the user based at least in part on the signal received from the one or more sensors by:
receiving images from the inward-facing imaging system and/or the outward-facing imaging system; and
analyzing the images to determine whether the frame is on top of the head of the user; and
cause the head-mounted display system to reduce power of one or more components of the head-mounted display system in response to at least in part on a determination that the frame is on the top of the head of the user.
