From: autodesk!unreal!robertj@uunet.UU.NET (Young Rob Jellinghaus) Subject: Accelerometers + cameras = better than Polhemus? Date: 28 Nov 90 20:49:38 GMT Organization: Autodesk, Inc., Sausalito, CA I know little about all this, but something occurred to me while reading the "accelerometers are sensitive but they drift" postings. People have reported work on using cameras to watch the VR voyager in the room, and track motion that way. Could one use a cheap camera and relatively in- efficient image analysis, combined with small, fast accelerometers, to implement drift correction without the need to stand still every once in a while? Would such a system have any chance of working better than a Polhemus--would response time be improved? Just kicking ideas around.... -- Rob Jellinghaus | "Next time you see a lie being spread or Autodesk, Inc. | a bad decision being made out of sheer robertj@Autodesk.COM | ignorance, pause, and think of hypertext." {decwrl,uunet}!autodesk!robertj | -- K.
