Slide Rule is a set of interaction techniques that allows users to interact with mobile touch screen-based devices without looking at the screen, by using gestural input and audio output. Slide Rule can make mobile touch screens accessible to blind people, and can be used by sighted people when looking at the screen is difficult, such as when driving or using a mobile device in your pocket.
