Current commercial message and research systems use softwargon program instruction execution and await a dedicated data processor for the throw- affect taska large, expensive, and complicated-to-use solution. In put in to make eye-gaze tracking ubiquitous, the system complexity, size, and price must be substantially reduced. This paper presents a hardware-based embedded system for eye detection, implemented using dim-witted logical system gates, with no CPU and no addressable frame bu?ers. The image-processing algorithmic pass along was redesigned to enable highly parallel, single-pass image-processing implementation.

A prototype system uses a CMOS digital imaging sensor and an FPGA for the image processing. It processes 640 · 480 progressive run over frames at a 60 fps rate, and outputs a contract appoint of sub-pixel accurate (x, y) eye coordinates via USB communication. Experimentation with detection of man eyes and synthetic targets are reported. This new logic design, run at the sensorÕs pixel clock, is suitable for single-chip eye detection and eye-gaze tracking sensors, and so making an important look towards press production, low equal systems.
