TouchTexting (or Text While Walking) is a hardware and software product which enables touch typing on the iPhone and iPod Touch. Now you can type while walking. The hardware is a plastic sheet with graphics braille dots on it. The Braille dots make up a 3x5 grid. Inside some of the grid squares are four software keys. As you slide your finger over the keyboard, you feel where the keys are, you hear a click as you slide onto the key, and when you release it, you hear the letter you just typed. This is touch typing with tactile and audio feedback. Depending on your hardware, you can send a text message, or an email. The software is free, the plastic covers can be ordered from the website.
Please do not review the app, unless you have tried it with the plastic covers.
