Taptilo is a new and innovative way to provide Braille instruction. It uses a combination of 9 removable, magnetic Braille cells which students use to create their own letters, and a permanent row of 9 refreshable cells which read and interact with the removable cells. Students can use one of 17 built-in self-study games with interactive audio to learn over 800 words. Or use the free app to download new games and content. Teachers can customize content and learning material based on a student's needs. Taptilo can also be used to learn Braille music and Braille math. Measures 17"x5"x2" and weighs 3 pounds. Comes with a headphone jack, and a shock and water resistant case with shoulder strap and handle. Approximate 7 day battery life.
