• Research to Market Transition of Mobile Assistive Technologies for People with Visual Impairments

  Sergio Mascetti, Dragan Ahmetovic, Cristian Bernareggi · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper examines why so few mobile assistive technology research prototypes for people with visual impairments ever reach end users, and shares practical lessons from the authors’ experience developing and distributing three iOS apps through EveryWare Technologies, a…

• Understanding Mental Ill-health as Psychosocial Disability: Implications for Assistive Technology

  Kathryn E. Ringland, Jennifer Nicholas, Rachel Kornfield, Emily G. Lattie, David C. Mohr, Madhu Reddy · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper argues that mental ill-health — including depression, anxiety, and other mental, emotional, or cognitive experiences — should be understood as psychosocial disability and examined through a social model lens rather than exclusively through the medical model that…
