What is it about?
This paper describes a two-part experiment. In part 1, participants used artificial sounds and echoes in a virtual world to identify: the size and material of virtual rooms, the presence of left or right turns, the presence of door-like openings and the presence of obstacles. In part 2, participants explored a virtual maze then used modelling clay to make a model of the maze

Why is it important?
This paper is important because it demonstrates that echo vibrations can help blind or low-vision people to understand virtual space. It is also important because it shows blind or low-vision people want to use virtual spaces to improve their orientation and mobility skills and also just for fun
Perspectives
The experiment described in this paper was done with blind or low-vision people. To create more accessible virtual spaces, we need to involve them in the design of these spaces. This work also demonstrates that sounds and echo vibrations can help blind and low-vision people explore virtual spaces.
