VBWriter allows people to practice writing Braille letters. The application speaks the name of a randomly selected letter and presents a touchscreen containing only empty dot outlines. The player double taps in the regions where the dots of the current letter should be raised. After the player submits an answer, the application confirms whether the input was correct, then presents a new letter.
