Hi! i have an idea to keep actualized the oculus quest 2 or meta quest "the new brand name" and make them compatible with the project cambria features. The oculus quest 2 has a lot of empty space in the front part. You can sell affordable modules to for example make it compatible with AR, with a couple of 4k or 2k cameras as the new cambria project has, and connect this module to the meta quest vrset. Another interesting feature is a module for tracking mouth expressions. This could be a small module on the bottom of the glasses that tracks mouth expressions and, depending on mouth movement, adds eye expressions to eye parts because quest 2 has no eye tracking.
