Multi-user eye tracking using multiple displays

Abstract

A system and method of securing data displayed to two or more individuals on two or more displays, wherein the two or more displays include a first display and a second display. One or more fixations of a first individual on the first display are determined. One or more fixations of a second individual on the second display are determined. A first frame buffer is associated with the first display. A second frame buffer is associated with the second display. Segments of the content in the first and second frame buffers are displayed while other segments are obfuscated.

1 .- 20 . (canceled) 
     
     
         21 . At least one computer readable storage medium having instructions stored thereon, the instructions when executed on a machine cause the machine to:
 determine one or more eye fixations of a first individual to an area of a first display;   determine one or more eye fixations of a second individual to an area of a second display;   associate a first frame buffer with the first display, the first frame buffer having content;   associate a second frame buffer with the second display;   display, on the first display, segments of the content in the first frame buffer corresponding to one or more of the eye fixations of the first individual to the area of the first display while obfuscating other segments shown on the first display;   display, on the second display, segments of the content in the first frame buffer corresponding to one or more of the eye fixations of the second individual to the area of the second display while obfuscating other segments of the first frame buffer being shown on the second display;   determine intersections of eye fixations by the first individual on the first display with eye fixations of the second individual on the second display; and   display, on the second display, segments of the content in the first frame buffer corresponding to the intersection of the eye fixations by the first individual to the area of the first display with the eye fixations of the second individual to the area of the second display,   wherein displaying on the second display includes copying content from the first frame buffer to the second frame buffer.   
     
     
         22 . The medium as recited in  claim 21 , wherein obfuscating includes applying an XOR mask to segments of the first frame buffer. 
     
     
         23 . The medium as recited in  claim 21 , wherein obfuscating includes replacing segments in the second frame buffer with random information. 
     
     
         24 . The medium as recited in  claim 21 , wherein instructions to obfuscate other segments shown on the second display includes instructions to displays segments of the second frame buffer corresponding to what the first individual is viewing on the first display. 
     
     
         25 . The medium as recited in  claim 21 , further comprising instructions to obfuscate segments where there is insufficient overlap between the eye fixations of the first and second individuals of the areas of the first and second displays, respectively. 
     
     
         26 . The device of  claim 21 , wherein segments that are not obfuscated when displayed remain that way for a defined period of time after the first individual stops fixating on that segment.
