The idea for the Cardboard Hololens is simple. Its design inspiration comes from google cardboard VR. Just like cardboard it uses your phone to display steroscopic images to simulate 3D content. But instead the phone is placed above your eyes and then the images are then reflected via semi reflective/ transparent glass into your field of view. This way the 3d content is mixed with the real world at a fixed depth.

Now the actual display technology behind the Hololens is far more advanced but, this is a work in progress, first build prototype. I will continue to work on new, and improved versions, and post DIYs so you can follow my progress. The ultimate goal for the cardboard hololens is to be a simple & cheap solution to simulating AR without having to pay for an expensive Dev Kit.
