my PhD: how people co-construct

How people co-construct a shared representation of space?

The cool/hot aspects of “spatialised communication” I can see so far can be so resumed:
a) catching inferences: building a framework to detect when and how people use spatial references to speed up the communication and problem solving process.
b) space meaning: what is the meaning of a place? [P. Durish: place and space]
c) space grounding: how is the groundign process different if people communicate with electronic media with/without spatial information? How is Mutual Modelling different?
d) social navigation: how is social navigation different because of space inferences?

In conclusion the topic is still undefined but maybe I can try to combine these theme to get to an interesting and unexplored topic.
