Using head gesture and eye position to wake a head mounted device

A non-transitory computer readable medium having stored therein instructions executable by a computing device to cause the computing device to perform functions comprising:

• receiving head-movement data that is indicative of head movement;
• detecting at least a portion of the head-movement data that is indicative of a head gesture;
• receiving eye-position data that is indicative of eye position;
• detecting at least a portion of the eye-position data that is indicative of an eye being directed towards a display of a head-mountable device (HMD);
• and
• causing the HMD to switch from a first operating mode to a second operating mode in response to the detection of both:
• (i) the eye-position data that is indicative of an eye directed towards the display, and (ii) the head-movement data indicative of the head gesture, wherein the eye-position data is received before the head-movement data, and wherein reception of the head-movement data is disabled until the eye-position data is received.

A computing device comprising:

• a display;
• a non-transitory computer readable medium;
• and
• program instructions stored on the non-transitory computer readable medium and executable by at least one processor to:
• receive head-movement data that is indicative of head movement;
• detect at least a portion of the head-movement data that is indicative of a head gesture;
• receive eye-position data that is indicative of eye position;
• detect at least a portion of the eye-position data that is indicative of an eye being directed towards a display of a head-mountable device (HMD);
• and
• cause the HMD to switch from a first operating mode to a second operating mode in response to the detection of both:
• (i) the data indicative of an eye directed towards the display of the HMD, and (ii) the data indicative of the upwards head gesture, wherein the eye-position data is received before the head-movement data, and wherein reception of the head-movement data is disabled until the eye-position data is received.
