Abstract:
An apparatus and method for performing real object detection and control using a Virtual Reality Head Mounted Display System, and more particularly, when the real object detection and control are detecting hand presence and control in free space, in a virtual reality environment, the control being, for example, gestures or movement, in the free space.

Claim (Index 18):
The system of  claim 17 , wherein:\n the determining of the horizontal swipe uses the color change sequence and is determined according to the following: S = { P \ue8a0 ( X , Y s , Z s ) } \ue89e \ue89e where \ue89e \ue89e X \u2208 { - Ws / 2 , Ws / 2 } S \u2032 = S \ue8a0 ( t + \u03b4 \ue89e \ue89e t ) \ue89e \ue89e where \ue89e \ue89e \u03b4 \ue89e \ue89e t \ue89e \ue89e is \ue89e \ue89e a \ue89e \ue89e unit \ue89e \ue89e set . \n \ue89e H = { S \u2032 \ue8a0 ( X + \u03b4 \ue89e \ue89e xi ) } \ue89e \ue89e where \ue89e \ue89e \u03b4 \ue89e \ue89e xi = iWs n \ue89e \ue89e and \ue89e \ue89e i \u2208 { 0 , n 2 } Where Ys and Z s  are the y-coordinate and z-coordinate of the real space blocks of interest from the mid-point between the video cameras  14 a ,  14 b , respectively. And W s  is the sum of the width of the real space blocks of interest which are tiled in x-direction. S is the series of target color occurrence values P(X, Y s , Z s ) for the real space blocks of interest at particular time t and S\u2032 is that at next time t+\u03b4t \u03b4xi is the shift distance of the real space blocks of interest. H is the collection of copies of S\u2032 with different shifting distance. Real \ue89e \ue89e Object \ue89e \ue89e Displacement = \u03b4 \ue89e \ue89e x \ue89e \ue89e and \ue89e \ue89e Real \ue89e \ue89e Object \ue89e \ue89e Velocity = \u03b4 \ue89e \ue89e x \u03b4 \ue89e \ue89e t . \n \ue89e If \ue89e \ue89e ( S \u22c2 S \u2032 \ue8a0 ( X + \u03b4 \ue89e \ue89e x ) = Max \ue8a0 ( S \u22c2 H ) \ue89e \n \ue89e and \ue89e \n \ue89e Max \ue8a0 ( S \u22c2 H ) > \u03b4 swipe Where \u03b4 swipe-  is the threshold value the determining of the double tap uses the color change sequence and is determined according to the following; S = { P \ue8a0 ( X t + k , Y t + k , Z t + k ) } S \u2032 = { S \ue8a0 ( t + \u03b4 \ue89e \ue89e t ) } \ue89e \ue89e where \ue89e \ue89e \u03b4 \ue89e \ue89e t = i 30 \ue89e \ue89e and \ue89e \ue89e i \u2208 { 0 , 30 } Where {k} are a target real space block and the neighboring real space blocks. S is the series of target color occurrence values P(X t +k,Y t +k,Z t +k) for the real space blocks of interest at particular time t and S\u2032 is a sequence of S at the following time frames.\n Double Tap=True if  S\u2229S double-tap >\u03b4 double-tap  \n where S double-tap  is pre-defined and \u03b4 double-tap  is the threshold value the determining of the single tap uses the color change sequence and is determined according to the following: S = { P \ue8a0 ( X t + k , Y t + k , Z t + k ) } S \u2032 = { S \ue8a0 ( t + \u03b4 \ue89e \ue89e t ) } \ue89e \ue89e where \ue89e \ue89e \u03b4 \ue89e \ue89e t = i 30 \ue89e \ue89e and \ue89e \ue89e i \u2208 { 0 , 30 } Where {k} are a target real space block and the neighboring real space blocks. S is the series of target color occurrence values P(X t +k,Y t +k,Z t +k) for the real space blocks of interest at particular time t and S\u2032 is a sequence of S at the following time frames.\n Single Tap=True if  S\u2032\u2229S single-tap >\u03b4 single-tap  \n where S single-tap  is pre defined and \u03b4 single-tap  is the threshold value
