[ba-unrev-talk] Drawing system for the blind

=4700923005    (01)

"Using graphics programs may be a daunting task for many people, and for 
the blind it is even tougher. While most graphics programs use a mouse or 
stylus for input, it is difficult for the blind to draw when they have no 
frame of reference to work with. Enter Hesham Kamel. Kamel is a blind 
engineering student at U. California at Berkeley and after having a project 
go past due because his illustrator was on vacation, he decided to develop 
a graphics program for the blind. His program IC2D (Integrated 
Communication 2 Draw) has allowed Kamel and others visually impaired draw 
themselves instead of relying on others to produce their illustrations.
Taking advantage of the universal familiarity with the layout of a 
telephone keypad, the program divides the screen into nine squares, each 
labeled with the corresponding numbers "1" through "9." Moving from square 
to square is just like dialing a telephone number. Each time a user enters 
a square, he or she has the option of subdividing it into another 
three-by-three grid, zooming in on increasingly finer details in the 
drawing. The program is capable of repeating the progression 81 times for a 
total of 729 possible squares."    (02)
