Abstract

Mobile devices with multi-touch capabilities are becoming increasingly common, largely due to the success of the Apple iPhone and iPod Touch. While there have been some advances in touchscreen accessibility for blind people, touchscreens remain inaccessible in many ways. Recent research has demonstrated that there is great potential in leveraging multi-touch capabilities to increase the accessibility of touchscreen applications for blind people. We have created No-Look Notes, an eyes-free text entry system that uses multi-touch input and audio output. No-Look Notes was implemented on Apple's iPhone platform. We have performed a within-subjects (n=10) user study of both No-Look Notes and the text entry component of Apple's VoiceOver, the recently released official accessibility component on the iPhone. No-Look Notes significantly outperformed VoiceOver in terms of speed, accuracy and user preference.
