This is a really odd article.<p>Using this device sounds awful!<p>><p>What I do want to talk about is how this entire system fundamentally screws with your brain in a way that I can barely understand, illustrated by seemingly straightforward questions of “how do I adjust the focus of the image” and “what if I want the image to seem closer or farther away from me?”<p>[...]<p>because the Smartglasses are using lasers to paint an AR image directly onto your retina, that image is always in focus. There are tiny muscles in our eyes that we use to focus on things, and no matter what those muscles are doing (whether they’re focused on something near or far), the AR image doesn’t get sharper or blurrier. It doesn’t change at all.<p>Furthermore, since only one eye is seeing the image, there’s no way for your eyes to converge on that image to estimate how far in front of you it is. Being able to see something that appears to be out there in the world but that has zero depth cues isn’t a situation that our brains are good at dealing with, which causes some weird effects.<p>><p>Oh wait, maybe it's not awful?<p>><p>for the first 10 or so minutes of wearing the glasses, your brain will be spending a lot of time trying to figure out just what the heck is going on. But after that, it just works, and you stop thinking about it (or that’s how it went for me, anyway.) This is just an experience that you and your brain need to have together, and it’ll all make sense.
