Robot-assisted wayfinding for the visually impaired in structured indoor environments
2006
Autonomous Robots
Preserved Fulltext
We present a robot-assisted wayfinding system for the visually impaired in structured indoor environments. ...
We describe how the system was deployed in two indoor environments and evaluated by visually impaired participants in a series of pilot experiments. ...
In the remainder of this article, we will argue that robot-assisted wayfinding is a viable universal access strategy in structured indoor environments where the visually impaired face wayfinding barriers ...
