• Haptic 3D Surface Representation of Table-Based Data for People With Visual Impairments

  Jonas Braier, Katharina Lattenkamp, Benjamin Räthel, Sandra Schering, Michael Wojatzki, Benjamin Weyers · 2014 · ACM Transactions on Accessible Computing

  This paper introduces "relief charts"—3D surface representations of standard data visualizations (bar graphs, pie charts, scatter plots, radar charts) designed to make complex tabular data accessible to people with visual impairments. The approach is grounded in neuroscientific…

• A Haptic Tool for Group Work on Geometrical Concepts Engaging Blind and Sighted Pupils

  Jonas Moll, Eva Pysander · 2013 · ACM Transactions on Accessible Computing

  This study investigates how haptic technology can support collaborative geometry learning between visually impaired and sighted pupils in inclusive classrooms. The researchers developed two haptic applications using PHANTOM devices: a static environment where pupils explore…

• Usability of a multimodal videogame to improve navigation skills for blind children

  Jaime Sánchez, Mauricio Sáenz, Miguel Ripoll · 2009 · Proceedings of the 11th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '09)

  This paper presents a usability evaluation of two complementary tools designed to help blind school-aged children develop orientation and mobility (O&M) skills in closed, unfamiliar spaces. The first tool is the Digital Clock Carpet (DCC), a custom-built haptic input device…
