Ever since I first saw heads-up-displays in science fiction movies like The Terminator, I knew that I had to get my hands on one. How neat it would be to get instant information on anything about anything in my field of vision?

Well, just as the iTablet won't be the Knowledge Navigator, the new buzz-phrase of the year, augmented reality, won't give me Terminator eyes. Such is life.

I tested out a pretty decent augmented reality app called Robotvision [iTunes Link], and for US $0.99 what you get, if you have an iPhone 3GS running OS 3.1 or better, is quite cool. Will it solve your problems, cure the common cold, or tell you anything that more established apps won't? Not really. But tossing a buck on a neat novelty is not unheard of in the iPhone 3GS world.

This one does more than most. First you tell it how widely to search and then, if you're in a highly populated area, you can set up a category ranging from ATMs to Travel Destinations. For the most part, I didn't fool with this since being in the suburbs, I can't be too picky.

Run it and the camera shutter opens. Moving the iPhone around, I found Cousin's Pizza, only 8432.1 miles away. Hmmm. The setting was for 5 miles. Wait, I guess it needed to be calibrated by doing the calibration figure eight wave of the phone. It seems that a lot of GPS apps require this.

OK, much better. It found a bunch of places but they were all stacked on top of one another. No big deal, since when you touch one, you get a screen like the one in the picture. The closest place is displayed first and the right and left arrows take you back and forth through the stack. While an item is in the front pane, you can call them, see them on a map (by cleverly pointing the iPhone to the floor, which invokes Google Maps, but all the stick pins aren't really any clearer than the AR view... maybe less so). You can also hit the Bing button where there might be a review or more information.

The problem is that the direction it puts you in is not quite accurate. It might get you to a nearby corner, but not to the butcher shop itself. I don't think we can slight Robotvision on this, since the not quite pin-point accuracy of the iPhone 3GS GPS has already been talked to death.

What else can this bad-boy do? You can see who is sending tweets in the area you specified, read the tweets and see how far the tweeter is from you. Not enough? Wait, there's more. You can find people in your area who use Flickr, and view their gallery. This doesn't work too well. I set the default for 50 miles and found no one. Then I set it for 25 miles and found one person with a gallery of 10 pictures. I live 30 miles from NYC, so I can't blame it on the boonies. You still want Ginsu knives? Okay, hit the Wikipedia button and see if anything in your range is listed. If so you'll get a bit of text and the option to go to Wikipedia to read more.

I don't know if AR will change the world, or be as successful as either New Coke or the iPod. But I'd suggest tossing a buck at this one. You are guaranteed 20 minutes of awe and then maybe some time to reflect on what you have, once the novelty wears off.

Check out this video for a tour and let us know what you think about this or the idea of augmented reality in general.

Earlier today I was reading about Metro Paris Subway [iTunes link], the first augmented reality (AR) app to hit the App Store and lamenting the fact that there wasn't an AR app for me to play with. Then we noticed this tip from Robert Scoble: It seems that Yelp for the iPhone has a hidden augmented reality feature. I downloaded the app and tried it out. I'm glad to say it works, but only on iPhone 3GS. Here's how to activate it (again, note that a 3GS iPhone is required):

1. Grab the app here
2. Launch it and shake your phone. Robert says you need to shake it 3 times. I got it working with one good shake, while other TUAW bloggers needed more than 3.
3. A message appears indicating that you've activated "Monocle." That's what they call the AR feature.
4. A monocle button appears on the top right of the app. Press it.

From there, the camera activates. Simply point your iPhone 3GS in any direction and take a look! I live out here in the middle of nowhere and was certain that I'd get a blank screen. Instead, Yelp found a number of restaurants, bars and other shops right away.

The screen is a bit jumpy and you've got to hold the phone REALLY still to get a good look. Plus, unlike Metro Paris Subway, the graphics depicting the different business aren't distinguishable (restaurant vs. bar, or example). Still, it's a lot of fun and a free way to play with augmented reality. Check out the gallery below for screenshots.

Grab Yelp [iTunes link] while you can and give it a try. Of course, we'd love to hear about your experiences.

There are two bits of knowledge that all native New Yorkers are gifted with: where to get "the best" pizza (Grimaldi's on the Brooklyn waterfront, in case you were wondering), and where to stand on the subway platform so as to arrive at the destination station in exactly the right spot to exit ahead of the rush. While this sometimes leads to bunching and crowding in the desirable cars, it ends up saving a lot of time and aggravation on the far side.

If you aren't a veteran straphanger, you can simulate the expertise of the locals with Exit Strategy NYC, a $1.99 iPhone app that tells you where to stand based on your destination station. The app is straightforward: select your train line and your direction of travel, then pick your arrival choice from the list. You'll get a clear diagram of the exit locations, along with the conductor's position in the train (great for late-night trips) and notes on any special circumstances, transfer options or wheelchair access.

In my tests, Exit Strategy matched my instincts pretty well with only a few hiccups (one exit that was closed for construction wasn't yet reflected in the app, but chances are us NYC residents wouldn't know that either). There is one drawback for outer-borough residents: while Manhattan and most near-to-downtown stations are included, some of the further-out stops, like my station along the R line in Sunset Park, Brooklyn, are not yet built in to the app. Still, Exit Strategy should definitely be part of your iPhone arsenal for a visit to the Big Apple. The demo video for the app is in the 2nd half of the post.

Despite their much-admired situational awareness, even NYC subway veterans sometimes get confused about where to find the nearest station -- and if you're a first time visitor, fuggedaboudit. For iPhone 3GS-enabled residents and tourists, it's about to get a lot easier: acrossair is offering an NYC version of the Nearest Tube augmented reality app, New York Nearest Subway.

Hold your iPhone flat and see a 2D map of the entire system... then lift it perpendicular to the ground, and the heads-up display mode shows you floating icons representing nearby stations, complete with line legends and walking distances. For anyone who's ever walked to a faraway subway stop only to realize that there was a much closer option, this is incredibly compelling. No word on price yet, and the app is awaiting approval; as noted, this app will only work on the 3GS, as the magnetometer is used to determine the direction the phone is facing.

If you've got preferred apps for navigating public transit in your city, pipe up in the comments.

When the fireworks stop and the smoke clears, it would be a great weekend to look at our beautiful summer skies. Pocket Universe [App Store] is a US$2.99 app that has been updated to make star finding easier for those that have a new iPhone 3GS.

The app uses the position sensors and the compass to orient your phone to match the real sky. As you turn or tilt the phone, the sky map changes to give you a very accurate picture of where you are pointing, with lots of labels and links to more information. This is one of the first examples of an augmented reality app to hit the platform since the introduction of the 3GS.

If you have an older iPhone or iPod touch running OS 3.0, you can tilt the phone to match where the real sky is, but you'll have to manually set the direction you're facing.

This changes everything for the novice astronomer. I tried the feature and it worked really well, even though I was near a large metal building. As I turned my phone the display of the sky changed very rapidly to keep up with my movement.

Other nice features from the last version are intact. You can tap the 'locate' button to find any object that is above the horizon. Select it and it centers on the map. Tap a pop-up for more info and you get a quick summary of the object. In the new version of the app a further tap gets you a Wikipedia entry.

You also get a list of meteor showers, lunar phases and a very nice 'tonight's sky' feature that tells you right away what's up and worth seeing.

Some things I'd like to see improved: The app could support finger-pointing to an object to identify it in addition to going to the locate menu, and the Virtual Sky feature is buried in an options menu. I'd like to see an onscreen button to turn it on and off.

The 3GS features are similar to a Celestron product called the Sky Scout that is a dedicated astronomical instrument. The Sky Scout has a lot more information, and audio tours of the skies, but it costs $200.00. If you're really serious about the stars and planets I'd give it a look.

Meanwhile, another favorite astronomy app, Distant Suns [App Store] has been updated recently, and is now on sale for US$3.99. It has added features to the wonderful tour guides and now includes more information about the objects displayed, including travel time at light speed to the planets. It also includes some breathtaking images from the Hubble Space Telescope.

This is the International Year of Astronomy, so it's a great time to get outdoors and look up. It's fun to do, and the iPhone apps really make it a more compelling and educational experience.

Here are some screen shots of Pocket Universe in operation:

If you caught the Copper Robot show on Sunday or any of our recent talkcasts, you may have heard me yammering at length about the possibilities for using the iPhone 3G S in enhanced or augmented reality applications. After the dynamic demo of compass-enhanced Google Street View on the Android Dream, the news of a magnetometer included with the 3G S -- allowing the phone to determine its direction with respect to the real world, along with position (GPS/SkyHook) and orientation/acceleration (accelerometer) -- starts to make geeks drool with eagerness for practical heads-up displays or browsable views of the world.

Here it comes, folks. As noted over at 9to5Mac, the Layar app from Dutch developer SPRXmobile will get Android phones into the realm of science fiction X-ray specs when it comes out at the end of this month. Point your phone across the street to see what houses are for sale, which bars are offering happy hour specials, or where the nearest ATM might be. A live, animated overlay points out the key locations and moves with your camera view. It's tough enough to describe, so I've got the video in the second half of this post -- but the effect is impressive. The previously-announced Wikitude app gives a travel guide the same augmented treatment for Android.

The guys at IntoMobile have given Layar a good once-over and come away quite awed. I can't wait to see this app, or one like it, make it over to the App Store. Add some social networking features from Brightkite or foursquare and iPhone users will jump all over this -- but they'll have to be careful not to walk into lampposts.
