An accessible robotics programming environment for visually impaired users

摘要

Despite advances in assistive technology, challenges remain in pre-college computer science outreach and university programs for visually impaired students. The use of robotics has been popular in pre-college classrooms and outreach programs, including those that serve underrepresented groups. This paper describes the specific accessibility features implemented in software that provides an accessible Lego Mindstorms NXT programming environment for teenage students who are visually impaired. JBrick is designed to support students with diverse visual acuity and who use needed assistive technology. Field tests over several days showed that JBrick has the potential to accommodate students who are visually impaired as they work together to program Lego Mindstorms NXT robots.
