Sony Eyepet

Read an article the other day that made me think of this project and could be worth a look, its a project Sony are developing for the Playstation called Eyepet, which takes a video feed of the user and puts a virtual pet over the top of it, creating the illusion that there is a small animal/monster on your desk, floor etc. An amazing element of this product however is the interaction you can have with the onscreen creature by interacting with it how you would in real life, for example if you stroke the air where it would be, on screen it will react as it would if you were stroking it, erm, probably not explaining it very well so heres a link that could be helpful in our idea development
