Metaio brings more augmented reality promises to the iPhone


I can't get enough of this augmented reality stuff -- we've seen a lot of location-based text rendering already, but a German-based company named Metaio has released this video showing actual 3D images and models projected into the world through a phone (like the iPhone, one of the devices they say they're planning to support). Of course, this is still all just tests and demos -- not only is the company likely still trying to see partners and funding (like so many other development companies in this field), but until Apple actually lets developers at a clear, unedited stream from the videocamera, AR is still in the theoretical phase.

But once again, the potential here is staggering. As I said, most of the things we've seen so far are based on text: hold your phone up, and have signs or other location-based information displayed to you. But when you start including 3D models into the mix, then things get really nuts: instead of just seeing tourist information, you could have a virtual guide show you around the museum. Or have a virtual hide and seek session with a creature that moves around the environment as you look for it. Other companies have been experimenting with AR on their own hardware, but Apple's combination of a video camera, a GPS/compass system, and a powerful handheld computer takes the possibility farther than we've seen it yet.

Augmented reality apps on hold until 3.1?

It was only a couple of weeks ago that straphanger hopes for an augmented reality guide to the NYC subways were flying high... and now it looks like they may have to wait for Labor Day before they can amaze their friends and stun their enemies. The LA Times is reporting a conversation with Acrossair developers where they indicate that the full-screen video features of the app can't ship before Apple releases iPhone OS 3.1 -- which they expect to drop in early September, in case you're marking your calendar.

According to the story, the live video/augmented reality approach depends on an unpublished camera API, hence the apps cannot be set free in the wild just yet. That may explain why several other inside-the-Matrix apps haven't cleared the store... and why September may see a bit of a surge in admissions to hospital emergency rooms for people with bruised foreheads and sheepish expressions.

Update 7/25: While the LA Times story is (so far) not yet updated, we have gotten feedback from a developer who insists that the 3.1 update will not provide additional hooks for AR apps; specifically, that the live camera view APIs are going to remain private and will not be exposed for third-party development. This source suggests that Acrossair is confused about Apple's position, and that the approval schedule aligning with 3.1 is a coincidence and not a technical restraint. We will try to reach Acrossair to confirm.

More AR, this time with Twitter, on the iPhone


Here's another augmented reality iPhone app that might be slightly more useful for those of us outside of London than the Nearest Tube app we showed off the other day. TwittARound is a Twitter client (currently in beta) for the iPhone that uses your location info, compass, and the 3GS' video camera to place tweets close to your location in a realtime video view, so that the effect you get is like pop-up notes on the landscape. Very cool indeed. Unfortunately, it seems many of these AR (augmented reality) apps may never see the light of day, as some developers are saying Apple doesn't provide any public API calls for the live video (hence this petition from the burgeoning AR community).

There are other issues here too, though, even if Apple does open up all of the APIs needed for a project like this. Twitter doesn't actually include location information with each tweet, so what you're actually seeing (I'd imagine) is the location of each Twitterer. What you'd like to do with an app like this is walk around and use it to get information about what you see (look through the app at a line outside a concert hall, for instance, and see people talking about who's playing inside). But unfortunately, unless they have some way of seeing exactly where those tweets come from, they'll all still be from each Twitterer's location, not where the tweet was actually sent.

But maybe Twitter or some other app can start including that location (Brightkite is already location-based, and works with Twitter), and then we can get real-time information from where we actually are on an AR screen like this. There's still a few obstacles, but once those are evened out, the possibilities are very exciting.

Nearest Tube's augmented reality on the iPhone 3GS

This (extremely loud, be careful) video has been making the rounds lately -- it's a demo of a new app called Nearest Tube that isn't quite in the App Store yet, but uses both your location information along with the iPhone's compass and video camera to show you an augmented reality picture of where and in which directions around you the nearest London Tube station is. Very cool use of the technology, and while I'm not actually in London to use it (and I don't have a 3GS -- obviously the compass is required to make this all work), it looks like it works pretty well. Some of you folks in London will have to give it a try when it gets approved and tell us what you think.

Oh, and the whole augmented reality thing -- get ready to hear that term a lot. On the TUAW team list, we were just chatting about microprojectors as well (rumored to be coming to iPhones and iPod touches), and as all of these technologies (video, projectors, compasses and location information) all start to get combined and hooked up to some serious computing power, your phone will be able to tell you more and more about what it sees in the world around you, from Tube or road directions like this app, to restaurants and stores, stars in the sky, and even other iPhones and their users. Hold on to your hats, because more and more, developers won't need to simulate the world around you when they can just show you an augmented version of it through your iPhone's screen.
