[accessibleimage] Re: Haptic rendering of images

Hi,
By supplementing images, do you mean sound and haptic feedback by a mouse?
When we tried it out it was sort of parallel with trying out the Virtouch.
So the idea was how to make
screen images available to someone who is blind. Hmm well it was just a
trial.  Isn't that what tools from
Sensable do?
At the time we just tried with a simple shape. The person who tried it out
was born blind.
Best,
Lisa
