electronics of the future-- more touchy-feely?

I have posted a few times about how electronics can be hard to use-- touch screens, tiny numbers, etc. This is probably the #1 thing people mention when I talk to them about what products/spaces are inaccessible by design.

Here are some lovely prototypes for electronic gadgets designed for blind people and people w/ low vision. The article mentions a watch, a camera, a debit-card reader/PIN interface, and a Braille reader/writer that all integrate new digital approaches to tactile display. The article also mentions how these applications could improve usability for all, as is the mantra of Universal Design:
"Of course, many of these technologies can provide benefits to sighted people. For example, a tactile surface could be applied to a bedside clock, enabling one half of a couple to find out what time it is without disturbing the other."
