An Evaluation of Accessibility of Hierarchical Data Structures in Data Broadcasting -Using Tactile Interface for Visually-Impaired People-
We have been developing a barrier-free information receiving system for the purpose of communicating information in digital broadcasting to visually-impaired people. In the service of data broadcasting in digital broadcasting, many items constitute the menu screen. In this report, presentation methods and access methods using touch in combination with audio for the purpose of effective communication of menu screen structure are briefly explained. Secondly, results of evaluation experiments conducted to obtain a guideline to design hierarchical presentation structures easily accessible by visually impaired people, using the tactile interface in combination with audio presentation were discussed by focusing on the hierarchical structure of menu screens in data broadcasting.
