Abstract
Eye motion is determined based on optical flow in images of an eye where the images are of reflections of light (coherent or incoherent) off of an eye. The reflections may be produced by selectively using one or more light sources and/or the images may be captured by selectively using one or more image sensors. For example, a subset of less than all of multiple available light sources and/or a subset of less than all of multiple available image sensors may be selected and used at a time based on the pose of the eye. One of the light sources and/or image sensors may be best suited for capturing images for eye tracking purposes when the user is looking left and while another light source and/or image sensor may be best suited when the user is looking right. The light sources and/or image sensors may be positioned to enable capturing images across the full range of eye poses.
