Haptic comparison of size (relative magnitude) in blind and sighted people
Sarah A. Douglas, Shasta Willson · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '07)
Douglas and Willson's Assets '07 paper is a controlled psychophysical study of how blind and sighted users compare relative magnitude using a PHANToM force-feedback device — the workhorse haptic input-output device of the era. The motivating problem is practical: accessibility…
