Dear Gordon,
Further to your message, are you by chance referring to the Graphiti –
Interactive Tactile Graphic Display?
If so, I had a short look at a prototype earlier this year and felt they have
missed a trick. I have a memory that it works in straight lines, it certainly
did at that
Hi Roger
Yep, that’s indeed the correct device. Unfortunately, I didn’t have it here
long enough to perform a very in-depth evaluation. So it’s very probable that
you’re correct. However, the guy who brought it to show me reckons you can now
move in any direction you choose. It contains 2437
