This was inspired by the instructable DIY VR http://www.instructables.com/id/DIY-VR/ and recently the VR GUN http://www.engadget.com/2009/06/21/diy-vr-game-gun-packs-built-in-motion-tracking-optional-mullet/
It's been 18 yrs since "The Lawnmower Man" was released. Sadly TRUE Virtual Reality never went mainstream.
Seeing the VR Game Gun video, I saw for the first time IMHO a viable VR system. This is my take on the VR Game Gun.
An Airsoft gun was my first choice for this build. The gun used is a Crossman Stinger R34 (M16 replica). The kit came with 2 clips, and reflex sight, it cost around $40 dollars. As with the other builds, a Gyration mouse was used for motion tracking. Instead of using the Gyration keyboard, an Xbox 360 wireless controller provided the rest of the input needs.
Force feedback was also a consideration. Luckily both XBOX 360 rumble motors fit into the handle. A solenoid from a sprinkler valve gives a satisfying report when the trigger is pulled.
Update: Uploaded test video in Vimeo http://www.vimeo.com/5950790 and
The clak-clak sound you hear in the video is the solenoid activating. Camera is duct taped to the left side of my head, so very bad camera angle. I'll find a wide angle adapter for my camera for the next video.
Keep an eye out, full instructable to follow in the next few days.
