Evaluation of Non-Visual Zooming Operations using Touch-Screen Devices
Publication Name: Proceedings of the 10th International Conference of Universal Access in Human-Computer Interaction
This paper summarizes the implementation, evaluation, and usability of non-visual panning operations for accessing graphics rendered on touch screen devices. Four novel non-visual panning techniques were implemented and experimentally evaluated on our experimental prototype, called a Vibro-Audio Interface (VAI), which provides completely non-visual access to graphical information using vibration, audio, and kinesthetic cues on a commercial touch screen device. This demonstration will provide an overview of our system’s functionalities and will discuss the necessity for developing non-visual panning operations enabling visually-impaired people access to large-format graphics (such as maps and floor plans).
