How BrailleTouch Works

Author's Note

Smartphones are some of the most prolific and powerful devices in the history of pocket-sized gadgets. Apps like BrailleTouch are a primary reason that smartphones are so appealing -- the software is cheap (in this case, free), the phones are relatively inexpensive, and best of all, these miniature computers empower all of us to do things that just a few years ago required the horsepower of a desktop computer.

But in the end, it's not even the elegance of the software or the efficiency of the phone's CPU that's so impressive. It's that developers keep finding new ways to help all of us, including those with significant physical limitations, share and communicate our ideas and feelings through the tools of the digital revolution.
