Lexi is an electronic device for learning Braille.
The project provides an interactive, tactile interface to simulate the raised dots that represent the letters of the print alphabet. Based on a system of six points, the device can generate any Braille character. As the user advances, these characters can be strung together to from words and sentences. Based on user preference, Lexi can either provide letters and words that the user must decipher or assess the accuracy of characters that the user inputs.
