You mean something like the work from Hugh Lusted, Ben Knapp and Anthony Lloyd at Biocontrol System? http://www.biocontrol.com/ I understand they have been working on a lower cost system designed for video games, etc. I dont know if it would be accurate enough for exact positioning on words, but it could at least detect the existance of saccades and fixations. I saw a video (circa '94-96) where it was used to control motion of an icon around a screen. ============= Jerry Isdale email: isdale@acm.org web: http://isdale.com/jerry fax: 805 496 8547
