HEAD NOD DETECTION AND CONTROL IN AN AUGMENTED REALITY EYEPIECE
This disclosure concerns an interactive head-mounted eyepiece with an integrated processor for handling content for display and an integrated image source for introducing the content to an optical assembly through which the user views a surrounding environment and the displayed content. The eyepiece includes a plurality of head motion sensing control devices that provide control commands to the processor as command instructions based upon sensing a predefined head motion characteristic.
1 . A system, comprising:
an interactive head-mounted eyepiece worn by a user, wherein the eyepiece includes an optical assembly through which the user views a surrounding environment and displayed content, wherein the optical assembly comprises a corrective element that corrects the user's view of the surrounding environment, an integrated processor for handling content for display to the user, and an integrated image source for introducing the content to the optical assembly; and
at least one of a plurality of head motion sensing control devices integrated with the eyepiece that provide control commands to the processor as command instructions based upon sensing a predefined head motion characteristic.
2 . The system of claim 1 , wherein the head motion characteristic is a nod of the user's head such that the nod is an overt motion dissimilar from ordinary head motions.
3 . The system of claim 2 , wherein the overt motion is a jerking motion of the head.
4 . The system of claim 1 , wherein the control instructions provide manipulation of the content for display.
5 . The system of claim 1 , wherein the control instructions are communicated to control an external device.
