• Evaluating a Tool for Improving Accessibility to Charts and Graphs

  Leo Ferres, Gitte Lindgaard, Livia Sumegi · 2010 · Proceedings of the 12th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2010)

  This paper presents two formative usability studies of iGraph-Lite, a natural language-based assistive technology that enables blind and visually impaired people to interact with statistical line graphs through keyboard commands and text-to-speech output. The system comprises…

• 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…

• Simulation to predict performance of assistive interfaces

  Pradipta Biswas, Peter Robinson · 2007 · Proceedings of the 9th International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS '07)

  This short ASSETS 2007 poster from Pradipta Biswas and Peter Robinson at the Cambridge Computer Laboratory describes a simulator for predicting how disabled users will perform on a given assistive interface, intended to reduce the dependence on hard-to-recruit disabled…

• A Mixed Method for Evaluating Input Devices with Older Persons

  Murni Mahmud · 2006 · Proceedings of the 8th International ACM SIGACCESS Conference on Computers and Accessibility (Assets '06)

  This exploratory study introduces a mixed evaluation method for assessing common input devices used by older persons. The author argues that traditional input device studies rely too heavily on experimental tasks like Fitts's Law pointing tests, which use controlled stimuli that…
