This is somewhat related to the Japanese Stereo TV thread, in particular the tracking of objects. Does anyone know of an inexpensive signal for tracking with a video camera? IE the object being shot has some kind of target attached to it and the camera is on a moterized platform. I seem to have seen something of the sort (with two sensors on the end of boom projecting from the base of the platform) but have not been able to track it down again. Application not: this is so people can take videotapes of themselves riding a horse and then self-critique their posture. Is this virtual worlds? Michael McCool@dgp.utoronto.ca

The camera would be aimed by swinging it in the direction of the stronger signal in the vertical and horizontal planes. If the "straight" pickup has the best signal, the camera is held steady. This has the problem that it must start out aimed at the target, and if the target moves faster than the device can rotate it will lose it. There are probably numerous technical problems as well, since I'm not a radio expert, but I think it might work. -- __ In Quest of Knowledge... /..\ --mm--mm-- Mike Gobbi (mgobbi@cs.ubc.ca)
