Exhibit Design Relating to Low Vision and Blindness Summary Report

Talking three-dimensional models for way-finding and orientation

Touchable models provide more spatially accurate information than the simple raised line map. A three dimensional representation of the physical environment is more easily spatially understood than a raised-line map of that space. Scale models provide information about building volumes and details that can provide valuable information about orientation in a space. However, without additional audio descriptive information to actually assist the blind user in navigating from the model to destinations within the space, models are not useful for way finding.

Talking map models with descriptive information are useful for orientation and navigation. Touch activated on-demand descriptions of model elements provide a better understanding of what the map reader is looking at. Some models provide information in a series of audio layers that are accessed by continuing finger contact with a single part of the model.
