Here is the text of the PDF:<p>This research aims to study and design a mechatronic system capable of rendering
images through a touchable surface to help the blind to read and understand these images.
This system uses mechanical and electronic techniques and integrated
software to convert
the gray image to a three
-
dimensional surface.
The mechanical mechanisms used with the control systems have been studied to reach the
design that is capable of transferring the fixed images to the mechanical system with the
possibility
of forming surfaces with suitable accuracy
.
The gray levels in the stationary
images were represented as a mathematical variable that changes on the Z axis in terms of
Cartesian coordinates where zero is considered black, and the maximum value expresses
th
e white and gray levels within the linear area of these two points The

image
processing library was used w
ith the C
# programming language to build an interface for
analysis and communication with the Arduino controllers, which acted as an intermed
iary
to link the image data and the
mechanical device (tactile display
) to display images for the
blind.
Finally all designed systems (mechanical, electronic and software) have been tested after
they have been successfully designed
.
Training of a group of
blind people was conducted
to test the system on several samples of images of different forms and the system has
demonstrated its ability to transmit multiple types of information.
