Locating Widgets in Different Tactile Information Visualizations

摘要

Large tactile displays demand for novel presentation and interaction strategies. In this paper, different tactile view types and orientation tools are evaluated with 13 blind users. The study has shown that the different view types are usable for different tasks. Orientation can be kept best in view types with Braille output but these are often not sufficient for graphical tasks. The usage of planar orientation tools, such as structure region or minimap, need to be trained to allow for an efficient support of two-dimensional tactual exploration.
