Personal Space

So I've been doing my first round of analysis and some codes/themes have been emerging. One of these was personal space, and particularly how the environment and the individual's actions affects this.

Coincidentally I came across this post by Alan Rapp on the Design Observer blog. It mentions Robert Sommer so I think I will take a look into his book Personal Space: The behavioral basis of design. I've also started finding a few articles on how things such as listening to music can alter people's perception and awareness of the space around them.
