Abstract: An example head-mounted device includes: a frame to nest the device on a head of a user; a biosensor disposed on the frame, the biosensor to: detect a biological characteristic of the user; generate a signal representing the biological characteristic of the user; and a power management controller coupled to the biosensor, the controller to, when the signal corresponds to a predefined profile, determine that the head-mounted device is in a transitional state and change a power state of the head-mounted device based on the transitional state.
