Climbing up the mountain of life and developing eye tracking system
      Lin Chia-Wei, male, born in 1978 in Kaohsiung, graduated from IT Engineering Department, National Sun Yat-Sen University. He suffered from congenital vertebra atrophy in recent 25 years, and was restrained to wheelchair from his childhood. Under the thoughtful attendance of his father Lin Yi-Hsin and mother Wang Feng-Yu, Lin Chia-Wei learnt how to tackle his life and challenge the destiny---learn hard, behave well, take delight in helping others.

      He was awarded with Mayor Prize at Kaohsiung City Ching Shan Elementary School, Chung Shan Junior High School and Hsiao Gang Senior High School, then admitted to Applied Mathematics Department, National Sun Yat-Sen University, and granted with “Letter of Commitment of Employment Package” and scholarship issued by National Sun Yat-Sen University as well as Booker Prize of National Sun Yat-Sen University. In 1999, he studied in a master program of IT Engineering Department, National Sun Yat-Sen University, and also interviewed by Mr. Li Denghui.?
      To build up a clean network and protect the youth against cultural contamination such as sex and violence, they established in Hsiao Gang Senior High School a free-of-charge website (http://hkhs.twbbs.org)--a first one in southern Taiwan. Meanwhile, they taught the disabled students how to operate computers in National Sun Yat-Sen University and Qiaosheng Tutorship Center. Lin Chia-Wei said this was the first step for him to make contributions to the society and his parents. In the last 25 years, he met the challenges of disease and attended various public activities. Also, he hoped to create an unlimited new computer world for the disabled around the world.
      In the last three years, Chia-Wei successfully finished his master dissertation--“Eye Tracking System” in IT Engineering Institute of National Sun Yat-Sen University, and applied the commonly used electronic devices (PC, Monitor, and PC Camera) for real-time tracking in combination of algorithm. In such a way, useful control signals are encoded to make it possible to operate system by eye, thus providing the disabled with a working environment of unlimited possibilities. The characteristic of eye tracking system is: everyone could perform eye tracking with a single host computer of high operating speed and a digital camera (e.g. videoconference camera), and other output devices are only used to control the current state, e.g. giving a warning with loudspeaker, or on-screen status display. 

      For example: the azimuth of eyeballs in relation to eye pupils is encoded for entry of letters like keyboard entry; or the azimuth is used to control the direction of cursor; the framework includes a camera facing the user’s head but being fixed elsewhere, a sufficient light source and a processor; the operating step is described below: 1. the camera captures an image of the user, mainly the entire face of the user ->2. analyze the image and find out the face area ->3. search the center of eye pupil in the upper part of face ->4. find out the profile of eyepit and obtain the central point->5. the azimuth of eye pupil’s center in relation to eyepit center is encoded as control signal ->6. return to step 1 for continuous tracking after completion of operation. In this case study, this is integrated software that’s available on-line for downloading, and some original program codes are provided for further improvement for the sake of the disabled.
