Construction of integrated simulator for developing head/eye tracking system

This paper describes the development of integrated head and eye tracker system. Head tracker is performed vision based and it has 7 mm error in 300 mm translation. The epipolar method and point matching are used for determining a position of head and rotational degree. High brightness LEDs are installed on helmet and the installed pattern is very important to match the points of stereo system. Eye tracker also uses LED for constant illumination. A Position of gazed object (3 m distance) is determined by pupil tracking and eye tracker has 1~5 pixel error. Integration of result data of each tracking system is important. RS-232C communication is applied to integrated system and Semaphore method is used for process synchronization.
