Enhancing Blind People’s Information Scanning with Concurrent Speech

Abstract: Blind people rely mostly on the auditory feedback of screen readers to consume digital information. Efficiency is a problem especially in situations where relevant information must be recognized among large amounts of irrelevant information. Sighted people use scanning as a strategy to achieve this goal, by glancing at all content expecting to identify information of interest to be subsequently analyzed with further care. In contrast, screen readers rely on a sequential auditory channel that …

Acquisition of Spatial Environmental Information from Tactile Displays

Abstract: It is still recognized as a challenge task while blind and visually impaired people travel outdoor independently, even if there are a number of assistive mobility aids available. In addition to building universal facilities in urban and rural environments for them, it is essential to develop novel mobility assistive technologies and systems to satisfy their increasing demands for mobility. To investigate those demands, an international survey with 106 blind and visually impaired people from …
