Abstract
A glare blocking system for selectively blocking specified glare spots. The system includes a transmission control material for selectively darkening a portion of the material and an electronics module for commanding the transmission control material to darken a specified area of the transmission control material. The system also includes a power source providing power to the electronic module and the transmission control material. The electronics module determines the specified area to be darkened upon the transmission control material to block a detected glare spot from view by a user. When a glare spot is detected, 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. In one embodiment, the glare blocking system includes a camera to capture an image seen through the transmission control material. Glare spots may then be detected on the captured image. The system may be used on goggles, visors, mirrors or as a panel having separate manual controls to select the areas to darken.
