          Blinding Protection Device For Blocking A Glaring Source With Minimal Interference Of The Visual Field

A smart glare / blinding protection device is disclosed herein for dynamically tracking and blocking a glaring source with minimal interference of the visual field. The smart glare / blinding protection device includes a camera that is used to emulate a user's field of view as well as to locate the position of the user's eyes. The smart glare / blinding protection device identifies a source of bright light that negatively affect the user, for example, temporarily blinding a driver, and tracks the source of bright light. The user's eye position is also identified and tracked in real-time. Thereafter, a trajectory of the source of bright light is calculated based on movement of the corresponding light source object. Additionally, an intersection between the source of the bright light, the position of the eyes for the user, and the transparent surface in between is calculated. After calculating the intersection, the smart glare / blinding protection device dynamically displays a light filter of right shape and size to temporarily dim or block the source of the bright light based on the intersection calculations. However, the smart glare / blinding protection device does not block the peripheral light emitted by the light source objects.

The smart glare / blinding protection device may use technology such as, a Liquid Crystal Display (LCD) or an Organic Light-Emitting Diode (OLED), and embeds the technology in transparent surfaces, for example a windshield and windows of a vehicle.

A filter effect is achieved by energizing the LCD or OLED embedded in the transparent surfaces. In embodiments, the smart glare device is attached to other devices such as, but not limited to, helmet visors, goggles and glasses to protect or enhance the user's vision. In addition, the smart glare device is applied to aircraft and homes for protecting the user's vision.

According to embodiments of the present invention, th...
