Braille PDA/Phone
awtbfb writes "ALVA B.V. has released details on their Mobile Phone Organizer 5500. This combination tri-band GSM phone and Windows CE.net PDA does not yet include GPRS, but it is supposedly in the works. Release dates are this summer. It's only been a year since this was requested in askslashdot."
The phone includes a one line braille display, which is essentially that.
My wife's phone, a Sanyo 4700, has something that's like speaking caller ID. It matches the caller ID with a phone book entry if possible, and speaks the name that you enter with the phonebook entry.
And if you think moveable nails are neat, you should see a whole refreshable braille display. I work with a guy that codes C all day long using one of these. It's truly amazing how people can adapt.
