Wink gesture based control system

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

• detecting a wink gesture at a head mounted device, wherein detecting a wink gesture comprises:
• determining intrinsic parameters of the wink gesture wherein the intrinsic parameters are selected from the list comprising:
• duration of the wink gesture, magnitude of the wink gesture, side of the wink gesture;
• and
• translating scalar values of the intrinsic parameters of the plurality of wink gestures to corresponding magnitudes of control inputs relating to input parameters of the user interface of the computing device;
• and
• translating the directional component of the intrinsic parameters of the plurality of wink gestures to corresponding direction of control inputs relating to input parameters of the user interface of the computing device;
• and
• translating the magnitude of a wink gesture to a corresponding control input relating to input parameters of the computing device using an exponential function.

A head mounted device system, comprising:

• a head mounted device;
• a wink detection system that is connected to the head mounted device, wherein the wink detection system is adapted to detect a wink gesture at the head mounted device, wherein the wink detection system comprises a plurality of sensors selected from the group consisting of electromyography sensors, distance sensors, motion sensors, infrared cameras, visual-range cameras and any combination thereof, wherein the wink gesture detected is selected from the group consisting of amplitude-dependent single-sided wink, duration-dependent single-sided wink, single-sided single-wink, single-sided double wink and double-sided single wink;
• a display;
• and
• a non-transitory computer-readable medium having stored therein program instructions that, upon execution by a computing device, cause the computing device to perform functions comprising:
• allowing the user to control smart applications through control inputs comprising the wink gesture and wherein the wink gesture can be used to achieve tasks from the following group consisting of resizing a virtual object, iterating between different virtual objects, shifting the active focus to a different virtual object, controlling movable virtual objects, and making or confirming selections;
• setting intrinsic HMD parameters comprising adjusting the speaker volume and adjusting the brightness of the display;
• and
• wherein the response to a wink gesture input may take into account parameters selected from the group consisting of magnitude of the wink gesture, duration of the wink gesture, number of repetitions of the wink gesture, the side of the face on which the wink gesture was performed, and any combination of the said parameters.
