Virtual reality attachment for a head mounted display

This is an accessory for a head-mounted display that projects images onto the real world. It uses a specially shaped prism to bounce those projected images directly into your eyes, effectively turning the display into a virtual reality device. The accessory can be attached or removed, and one version includes a small screen on the prism.

Why it matters: The manufacturing of custom freeform optics has become significantly more precise and cost-effective since 2016. This makes producing such an attachment for the now more common and advanced AR head-mounted displays more feasible.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom freeform optical prism
