Method of displaying private data to collocated users
First Claim
1. A method of displaying a first set of data private to a first user and a second set of data private to a second, collocated user on a display comprising:
- providing two pairs of stereoscopic glasses, a first pair for use by the first user and a second pair for use by the second user;
modifying the first pair of stereoscopic glasses to allow viewing of the display only in a first state and modifying the second pair of stereoscopic glasses to allow viewing of the display only in a second state;
displaying the first set of data to the first user on the display during the first state such that the first set of data is visible by the first user but not visible by the second user;
displaying the second set of data to the second user on the display during the second state such that the second set of data is visible by the second user but not visible by the first user;
displaying a third set of data on the display during the first and second states such that the third set of data is visible by the first and second users; and
alternately switching between the first and second states.

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.

11. A method of displaying data private to a first user and data private to a second, collocated user on a display comprising:
-
providing two pairs of stereoscopic glasses, a first pair for use by the first user and a second pair for use by the second user, the stereoscopic glasses having colored lenses, the first pair having lenses of a first color and the second pair having lenses of a second color; generating image data including the data private to the first user and the data private to the second user wherein the data private to the second user is to be displayed as a third color which transmits minimally through the first pair of stereoscopic glasses and maximally through the second pair of stereoscopic glasses and the data private to the first user is to be displayed as a fourth color which transmits minimally through the second pair of stereoscopic glasses and maximally through the first pair of stereoscopic glasses; and displaying the generated image data on the display. - View Dependent Claims (12, 13, 14, 15, 16, 17)
