I have actually considered how the environment can be used to send a signal directly to the viewer's eye. Even without BMI (Brain Machine Interface) this would make screens unnecessary altogether, and create a completely 360 degree Virtual Environment.
Goolag Glass shone an image on eyeglasses. It's but a short hop to shining directly in the retina itself.
Thanks!
Great point. There is also talk of contact lenses...not quite to the level of advancement you are mentioning but another means to view without a screen.
Baby steps.
