Just revealed at MacWorld: the SHOW WX Pico Projector. It's a video projector that can be connected to your phone and is roughly the same size as an iPhone.Technologies such as these will continue to shrink. We can imagine in the future computer displays built into the lenses of sunglasses or the human eyeball. Or perhaps we could connect a computer directly to the visual cortex of the brain.
In December, 2008 researchers in Japan successfully hacked into the visual cortex, extracting images directly from the brain. Now we just need to figure out how to input them.
