• "If you've gone straight, now, you must turn left" - Exploring the use of a tangible interface in a collaborative treasure hunt for people with visual impairments

  Quentin Chibaudel, Wafa Johal, Bernard Oriola, Marc J-M Macé, Pierre Dillenbourg, Valérie Tartas, Christophe Jouffrais · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2020)

  This paper from a collaboration between IRIT (Toulouse), UNSW Sydney, EPFL, and Université Toulouse investigates how tangible user interfaces — specifically a small graspable robot called the Cellulo — can mediate collaboration between two people with visual impairments in a…

• Haptic and Auditive Mesh Inspection for Blind 3D Modelers

  Sebastian Lieb, Benjamin Rosenmeier, Thorsten Thormählen, Knut Buettner · 2020 · Proceedings of the 22nd International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '20)

  This paper presents an affordable audio-haptic system that enables blind and severely visually impaired people to independently inspect 3D mesh objects they create using constructive geometry programming languages like OpenSCAD. Blind 3D modelers typically rely on text-based…
