AGENDA
Why blind people have to be limited to
information in Braille?

Transform contours of image to electrical stimuli.
Testing.
Objectives
7
Use inexpensive materials.
Blind people perceive the image with the sense of touch.

Objectives
8
Blind people can detect objects at a
distance without using the Braille
system (Replace the sense of sight with the sense of
touch and ).

Results and Conclusions
Time image processing with Matlab was 396.4 ms
The prototype meets the 15.75% of all images processed
by the human eye (16 frames per second).

Conclusions
The components used comply with the objectives proposed
of stimulation.
The prototype is economical.
22
With sensory substitution can replace the functions of
the sense of sight with the sense of touch.

Future outlook.
Stimulating array of pins with a resolution of 256 x 256 pixels.
23
Processing and reduction of the image should be automatic.

Future outlook.
Try other more complex shapes.
24
Using C language for image processing software decreasing
costs.
