Method and system enabling natural user interface gestures with user wearable glasses

An eye glasses wearable system enabling an unadorned user-object to communicate using gestures made in (x,y,z) space with an eye glasses wearable electronic device coupleable to a display having a display screen whereon user viewable imagery is displayable, the system including:

• an eye glasses system including an optical acquisition system operable to capture image data of said unadorned user-object within a three-dimensional hover zone, said optical acquisition system including at least two two-dimensional cameras;
• a processor;
• and
• memory storing instructions that, when executed by the processor, cause the processor to:
• define within said three-dimensional hover zone an interaction subzone including at least one z0 plane disposed intermediate a plane of said display screen and a plane at a maximum z-distance beyond which unadorned user-object gestures need not be recognized by said electronic device;
• process captured image data representing an interaction of said unadorned user-object with at least a portion of said interaction subzone to produce three-dimensional positional information of a detected said interaction, the processor further transforming the image data from coordinates corresponding to the optical acquisition system to world coordinates;
• determine at least one of (i) when in time, and (ii) where in (x,y,z) space said unadorned user-object first interaction occurred based on the three-dimensional positional information;
• identify a gesture being made by said unadorned user-object;
• and
• generate and couple at least one command to said display, said command having at least one characteristic selected from a group consisting of (I) said command causes altering at least one aspect of said viewable imagery, and (II) said command causes alteration of a state of said display regardless of whether an altered said state is user viewable.
