• RoboGraphics: Dynamic Tactile Graphics Powered by Mobile Robots

  Darren Guinness, Annika Muehlbradt, Daniel Szafir, Shaun K. Kane · 2019 · Proceedings of the 21st International ACM SIGACCESS Conference on Computers and Accessibility (ASSETS 2019)

  This paper introduces RoboGraphics, a novel approach to creating dynamic tactile graphics by combining a touchscreen tablet, static laser-cut tactile overlays, and small mobile robots (Ozobot Bit 2.0, approximately one cubic inch, ~$60 each). Traditional tactile graphics are…
