Some food for thought for my PhD topic

So far I can see three interesting directions for my PhD topic in the field of Spatialised Communication:

(a)- spatial inferences: how people use spatial inferences to restructure their work activity? How can we support this process?
(b)- spatial psycholinguistics: how space restructure and is being restructured by language? How can we facilitate these concepts to support teamwork and learning at large?
(c)- spatial opinion forming: how people form their mental representation of space? How they come to give a meaning to places? How can we support this opinion forming process?
