Method of displaying private data to collocated users

Abstract

Displaying data private to a first user and data private to a second, collocated user on a single computer display is achieved by providing two pairs of stereoscopic glasses, one for each user, and modifying the glasses by swapping one of the lens from the first pair with one of the lens of the second pair so that the modified first pair of glasses allows viewing of the display in a first state and the modified second pair of glasses allows viewing of the display in a second state. The data private to the first user is displayed when the display is in the first state and the data private to the second user is displayed when the display is in the second state. The display is alternately switched between the first and second states many times per second, thereby providing private displays for each user. In one embodiment, the stereoscopic glasses are polarized glasses and the display includes a polarizing filter. In another embodiment, the stereoscopic glasses are shutter glasses. In yet another embodiment, the stereoscopic glasses are colored glasses for viewing a composite image of the data private to each, with specialized colors used to ensure privacy of the display.
