• Using Dynamic Audio Feedback to Support Peripersonal Reaching in Young Visually Impaired People

  Graham Wilson, Stephen A. Brewster · 2016 · Proceedings of the 18th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '16)

  This paper investigates whether dynamic audio feedback — sound that changes based on the proximity between a reaching hand and target objects — can improve the accuracy of peripersonal reaching (reaching within arm's length) for blind and visually impaired young people.…

• Should I Trust It When I Cannot See It? Credibility Assessment for Blind Web Users

  Ali Abdolrahmani, Ravi Kuber · 2016 · Proceedings of the 18th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '16)

  This paper examines how blind screen reader users assess the credibility of web content compared to sighted users, revealing fundamental differences in credibility assessment strategies between the two groups. Web credibility — the believability of information and its source —…
