Patent ID: 7091928

Claim:
A real time control device for a machine by a human, wherein said control device comprises a machine stimulus generator that stimulates elements of said human, and a human response observer that observes observable human responses to stimuli generated by said machine stimulus generator, wherein said machine stimulus generator is a video display device having a video display for one or each of both eyes of said human, and wherein said human response observer comprises a first human response observer element and a second human response observer element, wherein said first human response observer element observes one or each of both eye balls relative to said one or respectively each of both of said video displays thereby enabling said first human response observer element to observe a visual focal direction of one or each of both eyes of said human, thereby determining through computation and prior calibration, the visual focal direction of one or each of both eyes with regard to locations of a stimulus on said one or each of both video displays—an object of gaze of said human, and wherein said second human response observer element observes motion of human response elements consisting of movement of one or both eyelids, which comprise a predefined set of patterns of Vclicks from one or both eyes, wherein each of said Vclicks consists of a single blink sequence of at least one blink, of one of the left eye defined as a Left Vclick or of the right eye defined as a Right Vclick or a combination of blinks of both eyes together or separately defined as a Both Vclick, and said predefined set of Vclicks constitute a Vclick Set, and furthermore wherein said observable human response comprise a predefined combination of said object of gaze of said one or each of both eyes as observed by said first human response observer element and at least one element of said Vclick Set observed by said second human response observer element substantially concurrently, said real time control device further comprising a plurality of distinct controllable cursors on said display device each having a distinct function, and each separately controllable by said human, said separate control comprising the object of gaze of one or each of both eyes of said human and separate and distinct predefined Vclick sequences of the human observed by said control device, thereby permitting said human to control a selection, deselection and movement of each of said one or more cursors.
