3.2.5. Information Hierarchy

To provide intuitive artwork information access, we divided the information into two layers:


The general information narration of the artwork is accessed only through the physical button on the IMG. Localized information is accessed by double or triple tapping on any of the points of interest in the relief model. Mapping the localized description to the point of interest being touched helps the user to relate what is touched (location, shape, and texture) to what is heard (localized information narration or sound). Sound design plays an important role in the IMG to communicate non-textual information. In collaboration with a music expert, background music was composed for each of the artworks to reflect the artwork's general mood. This track is reproduced through the entire exploration session. Sound effects representing the objects in each of the points of interest are reproduced on demand. The objective of these sounds is to facilitate the formation of a mental image of the artwork, using familiar sounds instead of images like sighted people would do.
