WebCam: a NetCam used on the WorldWide Web (WWW). Many WebCams exist in people's offices, and the like. What's original about the WearComp/WearCam presented here is that it is attached to someone as opposed to being part of the environment (attached to a wall, on a tripod, or the like).

NetCam: a camera that puts images onto the internet. The particular NetCam presented here is a wearable NetCam, rather than one that is fixed at a particular location.

Visualfilter: A NetCam combined with a display device, operating on a different channel than the NetCam (so that both can operate simultaneously).
