1. A method to enable 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 eye glasses having an optical acquisition system operable to capture image data, the method comprising: (a) capturing image data of said unadorned user-object within a three-dimensional hover zone; (b) defining within said three-dimensional hover zone an interaction subzone including at least one z 0 plane disposed intermediate said eye glasses wearable electronic device and a plane at a maximum z-distance beyond which unadorned user-object gestures need not be recognized by said electronic device; (c) processing image data captured at (a) representing an interaction of said unadorned user-object with at least a portion of said interaction subzone, defined in (b), to produce three-dimensional positional information of a detected said interaction, the processing including transforming the image data from coordinates corresponding to the optical acquisition system to world coordinates; (d) using said three-dimensional positional information produced at (c) to determine at least one of (i) when in time, and (ii) where in (x,y,z) space said unadorned user-object interaction occurred; (e) following determination at (d), identifying a gesture being made by said unadorned user-object; and (f) in response to identification of a gesture at (e), generating and coupling 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.
