From: "Peter Koch" Subject: -HOMEBREW- Wanted Cheap 2DO Date: 16 May 1997 11:20:53 -0700 Message-ID: Hi, I have built a HMD. Now, I need to do the head tracking. I would be quite satisfied to just have 2 DOF (yaw & pitch). The contraints I am working towards are: - Must not require external sensors - Must send data via standard serial - Must be small enough to fit in headset of course - Must be under US$200 I don't mind if it involves building a circuit, or anything like that. Just need some pointers. I haven't been into VR for a few years, did anything ever come of piezo-electric gyroscopes or magnetic compassess for head tracking? I have the homebrew VR book, and I'm planning on building the magnetic compass (LOHETS) project. Has anyone else done this, if so, any ideas to share, especially from anyone that used an A-D chip and a PIC to control the serial link back to the computer. Any help is greatly appreciated, as I want to use my HMD with real tracking now!
