To begin typing, begin typing.
My final project is a Braille typing interface. Since hardly anyone who can see can read Braille, and hardly anyone who can read Braille can see, It’s meant to be used as a venting system – like writing a letter you’ll never send. The program allows typing of all letters and some punctuation (i.e. question mark, space, enter keys). Once one has typed enough, the program will reset the canvas and repeatedly erase what the user has written. “Delete” will reset the canvas / program.
