This is How Google Glass Works [Infographic]

google glass works

Ready for the semi-scientific breakdown of the inner workings of Google Glass laid out in a simple infographic? Here you go. 

In short, the engineers behind Glass have created a mini-projector that blasts info into a prism that redirects imagery directly toward your retina, much of which depends on the placement of Glass on your head. This graphic also shows off the hardware setup behind Glass, including the location of the battery, CPU, speakers, microphone and camera in case you were wondering.

  • This infographic has some inaccuracies. Primary among them is that Glass uses a micro-display, not a projector. A projector focuses patterned light (i.e. graphics) onto a surface at a fixed distance from the image generator. Glass uses a micro-display which the user can ‘see’ by looking into a lensed prism.

  • Rob

    I get why it says “Speakers (phone)” but not “Micro(phone)” instead of just “Microphone.”

  • so people with glasses are out of luck right now?

    • gokusimpson

      Looks like it. I thought they were going to answer the question, but they didn’t.

    • yes but a little later they will release it for people with glasses

  • Chris Hollenbeck

    The Governor is out of luck…

  • J Dub

    He left out the counter weight opposite the battery and cpu….

  • Tin Foil Hats

    Where’s the part where it sends electromagnetic waves into your brain and causes tumors?

  • Wow, my wife’s gonna be pissed when she sees how much I spend on this on release day!

    • Handsome Jack

      I”m pretty sure you made some good money with the Da Vinci code.

      • Ha! …if I only didn’t hear that every day…

        • Larizard

          i lol’d

      • Brandon Golway


    • Do what I’m doing and start breaking it to her gently, slowly.

      “Hey babe, check out this cool new product from Google.” [show her the initial promo video from Google on YouTube.]

      A week or 2 later, show her another video. Tell her the ‘outrageous’ price, but look how cool it is.

      … go on like this, dropping subtle hints until it’s about to be released.

      • michael arazan

        Women don’t get subtle hints, they always get you the opposite of what you want.

    • im planning to buy 2 one for me and one for wife she wont be too pissed if i get her one right? lol

      • Justin Swanson

        That logic rarely works with wives…

        • michael arazan

          Tell her it will make shopping more fun. Now she can compare prices, use google goggles app to take pictures of the item and find cheaper prices from stores close to her using google maps.

  • TheWenger

    Get ready for the iTrolls to say “It’ll beam ads directly into your eyes!”

    • Lowry Brooks

      And then apple will come out with one, and it’ll be “revolutionary”

      • Justin Swanson

        And cost 4 times as much…

        • Lowry Brooks

          For half the features.

          • TheWenger

            But it’ll look pretty before you put a case on it.

    This product runs the risk of causing lazy eye in your left eye. It can ruin your sight in that eye. Google has been warned by optometrists.

    • Do you have a source? I have been wondering about that.

    • Tirionfive

      I am interested. Do you know where I can find an article explaining why?

      • Tim242

        It was discussed on a twit podcast. You can Google it to read about how it can cause the issue. Basically, Google Glass causes you to use the right eye more. Your eyes are pulling to the right. It causes the left eye to lose muscle strength and can reduce sight in that eye.

        • Tirionfive

          I googled and found nothing. In any case, couldn’t one theoretically swap which eye it is mounted on?

        • eyeman

          Maybe for constant use but the actual display isnt meant for 24 hour use most use would be between 1-5 mins this isnt meant to replace devices you already use. Also as someone who has a relaxed muscle on my left eye I wore a prismed lenses for a month and corrected the problem. A prismed eye glass lenses can force the lazy eye to work more and build muscle back

    • Chris Clancy

      Conversely, maybe it can cure someone with lazy eye by attaching to the opposite eye … glass is half full dude… c’mon

    • TheOiulkj

      I’d be money that an Apple fanboy is sailing that conspiracy ship.

  • Jason Kahn

    Glad to see Google patented it. I can’t decide if getting this is worth being classified king of the Nerds.

  • Spencer

    It’s going to be legen- WAIT FOR IT!….

    And hopefully we don’t have to wait for it too long,


  • sc4fpse

    Or, the tl;dr version: MAGIC!

  • All the talk about “projecting on the retina” has be very worried personally considering I’ve had 5 retina surgeries including laser-argon PRP and a pars-planar vitrectory.


    Don’t read about that if you get freaked out by alien abduction movies where they poke crap in peoples’ eyes.

    • Tin Foil Hats

      What? Google Glass can cause blindness?

    • ReturnOfTheMack

      Yeah I work with an Optician in an eye doctor’s office and have seen a few emergencies. retinal detachments and the like are not something to take lightly.

    • polioman

      This infographic is using technobabble to make Glass seem cooler than it is. The images aren’t being projected onto your retina more than any other light that enters your eye is. It’s just a tiny screen held right in front of your eye – this isn’t a laser or anything.

      This infographic is using technobabble to make Glass seem cooler than it is. The images aren’t being projected onto your retina more than any other light that enters your eye is. It’s just a tiny screen held right in front of your eye – this isn’t a laser or anything.

    • News flash: everything projects light onto the retina.

    • This infographic does describe a retinal laser projector, most likely a scanning laser video projector. If we guess the resolution is about 640*480, it would have a total of 307,200 pixels to scan with a moving laser. To be usable outdoors it would need to project at least as brightly as sun-lit objects, but the scanning nature means it needs to deliver this light energy in one 307,200th as much time as the equivilent object lit by the sun. The result? A laser beam 307,200 times brighter than anything you normally look at. That’s perfectly fine so long as the laser keeps moving, because it will never spend more than one 18 millionth of a second on any retinal pixel area. If the mechanism which scans the beam stops working however, that sort of beam could do some real damage quicker than you could react by closing your eye to the sudden bright light.

      And the thing which scans the beam is a moving mechanical device (maybe micromirror array, maybe spinning polygon mirror), so one day it will definitely stop moving. The question is, can google glass reliably switch the beam off when there’s a mechanical failure?

      I know I’m going to wait a few years before I try one of these on – I don’t want to be the first person to line cut in my retina by one of these. Pretty happy just looking down at my phone, even if it isn’t very masculine[1]

    SO COOL!!!

  • Tirionfive

    After seeing this on Gizmodo, I had one thing to say:


    • SallyRaster

      Careful. You’re starting to sound villainously like Josh over at the Verge whenever Apple throws one of their Sunday morning spirituals.

      • George L

        It’s funny cause it’s true.

      • No way, that’s maybe Josh about a year ago, but he’s now using the HTC One as his daily driver and a former Galaxy Nexus user.
