Environmental matching with limited displays

It is argued that to produce an informative spatial display on small devices one should focus on extracting distinctive features of the physical envi- ronment. These features can be communicated selectively to the user on small displays. By considering spatial, semantic, and visual information sources, one can generate cognitively adequate directions that foster spatial awareness, while limiting computational resources. This paper describes the issues involved in selecting appropriate elements within the cognitive collage of environmental spaces to generate such displays.
