• Haptic Gloves Prototype for Audio-Tactile Web Browsing

  Andrii Soviak · 2015 · ASSETS '15: Proceedings of the 17th International ACM SIGACCESS Conference on Computers & Accessibility

  This paper presents preliminary work on FeelX, a haptic gloves system designed to enable blind users to explore web page layouts through touch. The research addresses a fundamental limitation of screen readers: they present web content serially, creating a one-dimensional mental…
