Wink gesture based control system

A gesture-controlled mobile computing device comprising:

• a display capable of superimposing a virtual object onto a field of view, wherein said virtual object is capable of being manipulated through a user-commanded control input;
• a plurality of signal electrodes configured to measure voltage differentials between said signal electrodes and one or more reference electrodes, wherein said signal electrodes are needle-less surface electrodes;
• a wearable assembly wherein said assembly is configured to house said signal electrodes and bring said signal electrodes into dry, non-adhesive touch-based contact with a plurality of points on said user's skin when said assembly is worn, wherein said points are of a type which emit a voltage of myoelectric origin when a body part is moved, and wherein said assembly is of a type selected from the group consisting of:
• a frame comprising at least one temple tip and a nose bridge, or
• a hat, or
• a band wherein said band is capable of strapping said assembly to said user's skin;
• and
• a processor, wherein said processor is configured to determine an amplitude and a duration of a movement of a body part from said voltage differentials,
• and wherein said processor is configured to effect said control input on said virtual object and wherein said control input comprises a function of said amplitude and a function of said duration.
