A Prototype Interactive Tactile Display with Auditory Feedback
Tactile surfaces can display useful information in a variety of applications for blind, visually-impaired and even sighted users. One example is the use of paper-based tactile maps as navigational aids for interior and exterior spaces; visually- impaired individuals may use these to practice and learn a route prior to journeying. The addition of an interactive auditory display could enhance such tactile interfaces by providing additional information. This paper presents pre- liminary work on a prototype multi-modal interface which tracks the actions of a user’s hands over a tactile surface and responds with sonic feedback. The initial application being considered is an Auditory Tactile Map (ATM); the auditory display provides verbalised information as well as environmental sounds useful for navigation. Another pro- posed implementation adds interactivity to reproductions of museum exhibits, making these more accessible to the visually-impaired and allowing exploration of their tactile affordances while preserving the original works.
