This video is a demonstration of our prototype system that allows users to type on a touchscreen mobile device without visual feedback. This could be useful for users who are operating a device eyes-free or for users who are blind or visually-impaired.
Users are told to imagine an onscreen QWERTY keyboard at a location and size of their own choosing. Users then compose a message by tapping out the letters of each word on their imagined keyboard. A right swipe gesture is used to indicate the space between words. After typing a sentence, touching the screen with two fingers causes the tap sequence to be sent to our recognizer. The recognized text is then shown on the screen and played back via text-to-speech.
