Patent ID: 7651220

Claim:
A glare blocking system for selectively blocking specified glare spots, the system comprising: a transmission control material for selectively darkening a portion of the material; an electronic module for commanding the transmission control material to darken a specified area of the transmission control material; a power source providing power to the electronic module and the transmission control material; means for determining the specified area upon the transmission control material to block a detected glare spot from view by a user, wherein the electronic module using the user's eye position, position of the transmission control material and the camera to determine the specific area upon the transmission control material to block the detected glare; and means for calibrating an eye position of the user in relation to the transmission control material, the means for calibrating an eye position of the user includes using a substantially static object seen through the transmission control material and manually moving the specified area to darken to block the static object and extrapolating the position of the static object as seen from the camera thereby aligning the transmission control material relative to the eyes of the user; whereby the specified area to be darkened corresponding to a detected glare spot is determined and the electronic module directs the specified area of the transmission control material to be darkened to block the detected glare spot from view by the user.
