What's AR?

Augmented Reality (AR) vs Virtual Reality (VR).

Augmented Reality.

Augmented Reality. For a good example of current projects representing each field: Virtual Reality - Oculus Rift Augmented Reality - Google Glass AR sits on top of/alongside the real world, where VR tries to replace it.

  I'm not sure I'd call Google Glass "AR". It's just a small screen in your vision, it doesn't analyze or enhance your existing viewpoint in any way (unless I am mistaken). Cast AR is a better example: http://www.engadget.com/2013/05/18/cast-ar-hands-on-with-jeri-ellsworth-at-maker-faire-2013/ http://www.engadget.com/2013/05/18/cast-ar-hands-on-with-jer...

    Google Glass could be called a kind of "proto-AR". It could certainly be a first (significant) step toward real AR.
    - untog 13y ago
      Not really. In terms of AR, Google Glass is doing absolutely nothing new, so it wouldn't be the first.

        Nothing new by default, but its opening up a lot of hardware potential. Its not just a screen and camera that's at eye level, its also setting new social norms that make that acceptable. Even now, Glass isn't far from Bluetooth levels of socially okay, which is say annoying to most but acceptable. Once it reaches that point, I expect AR to be a focal point of development. It only makes sense. A simple street view overlay + wikipedia filter would be basic AR, and that doesn't seem difficult at all. Google could monetize with virtual window ads that businesses would buy for glass+streetview users.

        A simple street view overlay + wikipedia filter would be basic AR, and that doesn't seem difficult at all. It would be extremely difficult. It would use a lot of processing power to examine the camera input and attempt to extrapolate positioning for overlayed elements. I'm not sure Glass has that power.

        >It would use a lot of processing power to examine the camera input and attempt to extrapolate positioning for overlayed elements. What camera input? Why go all in such a roundabout way, processing the image to determine the location? What he proposes just needs the GPS/compass (if Google Glass has one, else it's trivial to add one). You get relevant wikipedia articles for your location (including the direction you're looking) using Glass's GPS, and the screen displays them.

        Nope. GPS isn't anywhere near accurate enough for that- believe me, I've tried. It's usually accurate to a few meters, which is fine for an overhead map, but would be horribly jarring when used for AR.

      Right now your phone is as much AR as the google glass. Now if Google starts letting us use the camera for face recognition we could see some proto AR stuff.

        As someone with terrible face recognition ability, I was really disappointed Google disallowed the feature. Such a device could vastly improve my life. I hope there's some open alternative to Google glass soon.

    A smartphone is a better AR platform than Google Glass because you can hold it up directly in front of your field of vision and use AR apps. Google Glass is wearable, but the display position is fixed relative to your head. You have to look up to see the screen, so unless you tilt your head down in some awkward manner to point to what you want the AR overlay on, it won't work. Not a very good AR experience.

    AR is any augmentation of senses, so a wristwatch is AR for your sense of time for instance. Google glass doesn't do predator-vision, but it can augment stuff like memory or positional awareness.
    - Aloisius 13y ago
      AR integrates computer-generated sensory input realistically into reality. A wristwatch and Google Glass are no more AR than a piece of paper with a map on it is.

  Nintendo 3DS actually has basic demonstrations of AR as well. They use cards with images on it that can be replaced in real-time by simulated 3-D objects using the 3DS camera.
