Livescribe Pulse Pen is a commercial smart pen device that includes a video camera in its tip, a microprocessor that can run Java programs, memory, an audio speaker, a microphone, and a rechargeable battery. As the pen is touched to specially-printed paper, the camera “sees” a pattern of tiny dots (commercially known as the Anoto pattern) that encodes page and pixel coordinate data, and can deduce its position on a printed surface. In the audio-haptic applications proposed here, the pen will speak the identities of any feature of a raised-line graphic that has been touched by the pen’s tip, and will permit complex interactivity with materials such as maps, curricula, games and reference tools. Users can detect by touch not only raised surfaces but indentations such as channels, dimples and punched holes, subtle features not discerned by the fingers alone. Users can first explore these images with their hands; then they can tap the pen’s tip to any feature to cause descriptive text to be played through the pen’s speaker or through connected ear buds. By this means, vision impaired readers can access complex pictorial material with good comprehension, and the raised-line graphic can also become the basis of a graphical user interface, allowing authors and artists to make highly interactive static images that communicate through multiple sense channels.
