How on earth do people focus at that distance? I know I could never now, and I doubt I could when I was younger. It’s like what, an inch from your eye?
Is there something I’m missing?
It actually projects the image directly onto your retina, which is all the way in the back of your eyeball. Here’s a cool series of infographics.
Wooh. The ultimate heads up display.
Thanks
Only really in the sense that anything you look at projects an image on your retina.
The image is just focused so that it appears at a greater distance away than the eyepiece.
I have one very dominant eye (my left), so things like 3-D glasses don’t work for me. I wonder if I’d be able to use Google Glass?
It projects an image purposefully sized and focused to arrive at your retina in such a way that it allows you to clearly see and focus on something significantly less than ~1" from the surface of your eye when you normally wouldn’t be able to.
Better?
It creates a virtual image with an object distance that is further away than the lens. Your eye focuses this onto your retina, just like it does everything else.
What’s the best, most succinct way to describe the method by which it accomplishes this? Because that doesn’t really tell you much about the how.
The ultimate heads up display would be generated right into the visual cortex of the brain. This is the next best thing ;).
I don’t want to get into a pissing match over terminology - whatever you like.
That would not actually work. Our visual experience is not an experience of an “image” in the visual cortex, and there is almost certainly no way to produce a coherent visual experience (i.e., experience of a scene or object, as opposed to phosphenes: random blobs and flashes of light, and maybe certain simple patterns) by direct stimulation of it (or, indeed, of any, many, or all of the brain’s visual areas, cortical and otherwise).
