So I am pretty lost with my thesis right now. I just do not know how to make the connection between graphic design and human communication. The topic is pretty broad so I am trying break it down to make it more simple. However I feel lost.

There are so many components, like using this blog for example is now a form of communication, twitter, my space, are all forms of communication. However you cannot see facial expression or body language yet dating sites are very popular. How can you really know a person without being able to see emotion in their body and face.
