I have seen that before, but to be honest it doesn't look too interesting. I was thinking more like accessing your e-mail on your wall or having virtual characters walking around your house. I would buy something like that in a heartbeat. Sony's Smart AR looks like it could have some potential; the other AR devices I've seen aren't very accurate and the 3d models tend to shake around a lot. That's not the case with this. I'm interested in the future applications Sony's going to develop with this technology.
