Patent abstract
Systems and methods are provided for a compact eye-tracking camera assembly. The camera incorporates a lens and image sensor whose principal axis is parallel to the plane of the display surface, and a compound angle mirror configured to redirect incident IR light along the principal axis. The compound angle mirror has a first angle of approximately 45 degrees relative to a first axis, and a second angle of approximately 15-22 degrees (e.g., 18 degrees) relative to a second axis that is orthogonal to the first axis. The first and second axes are substantially parallel to the plane of the display surface.
