A formidable training and development tool, this high-performance VR display system surrounds the user in wide-view 3-D imagery and realistic sound. By keeping part count low and simplifying the build scheme, we were able to meet cost targets despite low production volumes. To enhance comfort and reduce neck fatigue, we counter-balanced the front optics with the rear magnetic tracker and cable assembles. Other features designed to boost user comfort include earphones that are easily detached when not needed (to minimize weight) and a rear adjustment knob and self-adjusting top strap for a precise fit.
