3D shutter glasses with mode switching based on orientation to display device
First Claim
1. A system for providing respective video signals to at least two viewers, the system comprising:
- a control unit; and
a display connected to said control unit;
wherein the control unit is operable to control the display to alternately display an image from a first video signal and an image from a second video signal, to synchronize a first shuttered filter to the display such that the first filter is shuttered when the second video signal image is displayed, and to synchronize a second shuttered filter to the display such that the second filter is shuttered when the first video signal image is displayed, wherein the first and second video signals correspond to left and right perspectives of a three-dimensional scene viewed by a first viewer, wherein the control unit is further operable to time multiplex display of the first and second video signal images on the display with display of images from a third video signal and to synchronize the display of the images from the third video signal with operation of a third shuttered filter such that the third shuttered filter is shuttered when the first or second video image is displayed and the first and second shuttered filters are shuttered when the third video signal image is displayed thereby providing only the first and second video signal images to a first viewer using said first and second shuttered filters and providing only the third video signal image to a third viewer using said third shuttered filter.

Abstract
A shuttered filter apparatus comprises a frame, one or more shuttered filters attached to the frame, and a tracker attached to the frame. Each shuttered filter is configured to selectively prevent a viewer from seeing through the filter in response to a signal from a controller. The tracker is configured to sense an orientation of the one or more shuttered filters relative to a video screen. The controller may use a signal from the tracker indicative of an orientation of the shutter filter(s) relative to enable shuttering when the shuttered filter apparatus is facing toward the video screen and disable shuttering when the shuttered filter apparatus is facing away from the video screen.
