Abstract
Embodiments describe an eye sensing module to detect eye movements and gestures. The eye sensing module is included in a head wearable display, and may be placed anywhere within the head wearable display so that the image sensor device has a line-of-sight to the user's eye. The eye sensing module comprises an image sensor, an array of focusing lenses disposed over the image sensor placed side-by-side (i.e., not on top of one another), and a corresponding array of directional prisms disposed over the focusing lenses. The directional prisms and the focusing lenses increase the field of view of the image sensor to enable the image sensor to capture eye gestures and eye movements for different user eye sizes, eye locations, and other varying eye characteristics. These eye sensing modules increase the field of view of the image sensor without increasing the size of image sensor or focusing lenses.
