Exploiting the advantages of planar tactile displays, we aim for efficient and effective information retrieval for blind users.
To facilitate orientation, we define four regions segmenting the available space: header, body, structure, and detail region.
Furthermore, we suggest four views—layout, outline, symbol and operating view—that define how detailed and in which manner
information from window-based applications is displayed on tactile displays.
