• Route Descriptions, Spatial Knowledge and Spatial Representations of Blind and Partially Sighted People: Improved Design of Electronic Travel Aids

  Marion Hersh, Alasdair Ramirez Garcia · 2022 · ACM Transactions on Accessible Computing

  This paper presents a qualitative study investigating how blind and partially sighted people acquire spatial knowledge, form mental maps, and describe routes—with the goal of informing better design of electronic travel aids (ETAs). The researchers worked with nine participants…

• Beyond the Cane: Describing Urban Scenes to Blind People for Mobility Tasks

  Karin M. P. Hoogsteen, Florian Mathis, Garreth W. Tigwell, Alastair R. Beresford, Mohamed Khamis · 2022 · ACM Transactions on Accessible Computing

  This research investigates what environmental information is most useful for blind pedestrians navigating urban spaces, moving beyond obstacle-avoidance to understand comprehensive scene description needs. The authors conducted two experiments with 13 cane-using blind…

• Tactile Working Memory Capacity of Users Who Are Blind in an Electronic Travel Aid Application with a Vibration Belt

  Jan B. F. van Erp, Katja I. Paul, Tina Mioch · 2020 · ACM Transactions on Accessible Computing

  This paper investigates the tactile working memory capacity of users who are blind when using a vibrotactile belt for electronic travel aid (ETA) applications. ETAs that display obstacle information through vibration belts require users to integrate multiple tactile cues over…
