Internet to the capabilities provided by the car.

We are aware of a few other similar projects. Some of these involve tele-operation of cameras or

robots over the Internet. These efforts lack the rich functionality provided by our telepresence - for exam-

ple, Internet cameras cannot be moved around, only panned or zoomed. Other presences are confined to the

local area, and do not leverage the existing packet video infrastructure in the Internet. We believe that our

presence is the first to marry the mobility of a car to the packet video standards in the Internet and the

MBONE.

Operating a model car, airplane or boat from a computer screen gives us a different and more realistic

feel than the normal method of operation. Using a network to operate a vehicle is entirely compatible (for

cars, not airplanes) with the slow video provided by the Internet or a videophone and is, in fact, a more use-

ful application for this than the too slow "talking heads" application for which they are normally used.

Teachers of the handicapped understand that video is more useful for dealing with things than people.

There is a saying among them that being deaf cuts you off from people and being blind cuts you off from

things. Perhaps this is the right way to use packet video, not to look at people, but to look at (and eventually

manipulate) objects.
