This again? As usual, the problem is casually swept away deep in the text:
> By now you’re probably wondering how a person wearing one of our contact lenses would be able to focus on an image generated on the surface of the eye.
Yes, that is a bit of a problem. I'd say it's the main problem. Quite a bit of hand-waving here, just like the many other contact-screen speculations.
- twistedpair 13y agoGot a minor in optical engineering minor back in the day. I think it is theoretically possible to create a waveform with those LED's that would converge to an image at a distance. It's a similar problem to the recent deep field cameras on the market today that look at the waveform across the thousands of lenslets and reconstruct the image at multiple virtual focal planes. That said, those calculations are wicked complicated and take computational power, so hopefully some genius PhD comes up with an algorithm to generate those wavelet images in O(n).
- XorNot 13y agoAn array of lasers which was columinated at the point of emission could do it (a well of 500nm cavities, with an LED module at the bottom could do it. On the other hand: tensor displays are basically already there for what you say (http://www.youtube.com/watch?v=4r6lY8S4A6E http://www.youtube.com/watch?v=4r6lY8S4A6E). It's a pretty solvable problem, we're just lacking the miniaturization (and power source) to make it practical.
