FPGA Design of User Monitoring System for Display Power Control

Abstract

This paper introduces new FPGA design of user-monitoring system for power management of PC display. From the camera readings the system detects whether the user looks at the screen or not and produces signals to control the display backlight. The system provides over 88% eye detection accuracy at 8f/s image processing rate. We describe new eye-tracking algorithm and hardware and present the results of its experimental evaluation in prototype display power management system.
