Developers at the University of Michigan are working on a Braille-based Kindle for the blind. In addition to e-reader capabilities, the device will allow people who are blind to surf the web in a way they were previously unable to do: Users will be able to interact with photographs, spreadsheets, and graphs.
Refreshable Braille technology has been around for a while, but like many types of assistive technology, it can be prohibitively expensive. Single-line devices can cost several thousand dollars, and multi-line devices can cost tens of thousands. One of the goals of the Braille Kindle project is to create a multi-line device that will retail for around $1000 to $2000 once it is finished.
