Virtual reality attachment for a head mounted display

This invention describes an add-on for augmented reality headsets that project images onto the real world. It uses a special prism, sometimes with a screen, to redirect those projected images directly into the user's eyes. This effectively switches the headset from showing virtual objects in the real world to a fully immersive virtual reality experience.

Why it matters: In 2016, AR projection displays were less common and sophisticated. Advances in compact AR headset design and freeform optics manufacturing could make this attachment more practical and effective today.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom freeform optics, precise mechanical attachment
