PERKINS VISIT

+ SECONDARY RESEARCH

؜From the Perkins visit we saw how they had some very unique ways of navigation like audio, slanted floors, and special maps. From this we thought that some sort of map that blind people could use would be helpful. We were inspired by Braiile and decided that a good way to try this would be with some sort of dot layout that could change based on the space that you are in.

PROJECT STATEMENT

A device that communicates information about the users environment using air driven bumps that can dynamically change. This allows users with less information in a new place be able to avoid obstacles.

EXPLORATION

PROTOTYPE 1

Initial prototype for inflation.

PROTOTYPE 2

Casted mold along with failed mold. It could be successfully inflated but not quite finished, and had no holder. No electronics main issue would have to be manually inflated.

PROTOTYPE 3

The electronics are essentially just a transistor for every valve so we can give each valve 6V.

FUTURE CONSIDERATIONS

Get the center actuators hooked up

Add a larger power supply such that we can power all valves at once

؜Increase size and resolution
