Attorney, Agent or FirmInternational ClassA61B 005/00AbstractA retinal scanning display, an active-pixel image sensor array, and an im processor track the movements of the human eye. The scanning nature of the display acts as a sequential source of eye illumination. The active-pixel image sensor array is directed toward the cornea of the eye through a matrix of micro-lens. The sensor is integrated with a comparator array which is interfaced to bilateral switches. An element address encoder and latch determines the sensor element which reaches maximum intensity during the raster-scan period of the display driver. Over a display field refresh cycle, the invention maps the corneal surface to a data table by pairing sensor activations to the specular reflections from the cornea of the sequenced source lights. | |
