- StavrosK 14y agoI have a question I haven't seen answered anywhere: How does these glasses work with focus? When I'm looking (and focusing) 5 meters away, how can I see an object overlaid there? Surely, I'd have to focus on the glasses, 3 cm from my eye, no? How do they fix that?
- sageikosa 14y agoAt a guess, it would track iris dilation to determine your focus depth.
- StavrosK 14y agoI'm not really sure it's active, but still, the question of how you get something on a surface to become visible when you focus meters beyond that surface remains.
- CognitiveLens 14y agoIris dilation is primarily a response to light levels, not focus depth. Focus comes from stretching the lens behind the iris, which is possible to sense externally, but much more difficult.
- teraflop 14y agoYou can use lenses or mirrors to change the apparent focal distance of an object. Google's implementation is rumored to use holographic optical elements instead, probably for compactness: http://www.google.com/patents/US3940204 http://www.google.com/patents/US3940204
- StavrosK 14y agoAh, very interesting, thank you.
