Information

There is another basic need for visual information that goes beyond the specific information required for a particular activity. This is not related to any particular situation, it results from man's biological need to understand the world especially man's need to feel safe. To evaluate danger, we must be aware of the structure of the environment. This applies to orientation, weather ,time of day and information relating to other activities occurring in the area. If this information is not available, e.g. in large, windowless buildings, the situation is often considered to be unnatural and oppressive.
