Claim Text:
1. An apparatus for viewing a stereoscopic display, comprising: a pair of active shutter lenses, each lens enabled to alternate opacity and transparency to allow a transmission of a first set of images directed to a first eye through a first lens and transmission of a second set of images directed to a second eye through a second lens; a roll orientation sensor for detecting a roll orientation of the lenses; and a circuit connected with the active shutter lenses, the circuit configured to switch the lenses from alternating opacity with respect to each other to synchronizing opacity with respect to each other based at least in part on a signal from the sensor to allow transmission of the first set of images through the first lens and second lens while blocking transmission of the second set of images by the first lens and second lens, the signal indicating exceeding a threshold based at least in part on roll orientation, wherein the circuit is configured to delay switching the lenses between opacity and synchronization for a period of time to confirm that the threshold is exceeded.
