An opportunity is emerging for head mounted displays if the optics can be designed to provide an immersive wide field of view with little to no adjustment for different users. The need for such a display is becoming plain as computer graphics and 3D content become ubiquitous and generic, yet current of head mounted displays remain expensive and finicky. Such a design is now possible due to emergent optical technologies coupled with recently available, low cost microdisplays. Our design approach uses these components in unconventional ways to create a 120 degree field of view display easily used without adjustment. Having previously produced a similar product but at a high price and large size, we find this confluence of technologies and our proposed design impossible to ignore. We believe we can create a mixed-reality display ideally suited to the AVCATT and other simulation environments
