Technology has made it possible for the blind to function, be more productive, and be independent.
Since drawing software typically has a purely graphical user interface, blind users have had only limited success in using this software. The purpose of this research project is to address the problem of computer aided drawing for the visually impaired. This problem is as challenging as having a sighted person use a computer to draw with the monitor turned off. One of our main goals is to allow a blind person to select a desired point on the screen, move the cursor to perform another task at a new location, and later relocate the cursor back to the original point. Approximate relocation of the point is often inadequate.
