Webcams and VR
I have always thought of virtual as something abstract: not fantasy but a model or an imagined object. With the virtual technology, VR comes to mean not the act of imagination but the technology which makes the model or representation possible. Sometimes that meaning makes sense to me.

Michael Naimark writes of Virtual reality - VR - and webcams in an article for ISEA 2002 in Japan this month. It's a short and easy little paper, but he makes some interesting observations about VR technology and the role of webcams, and the distinction between webcams and VR technology. While I think that he might be comparing apples and oranges, I think he finds some important qualities which can bear mentioning in both cases.
