In Insert Coin, we look at an exciting new tech project that requires funding before it can hit production. If you'd like to pitch a project, please send us a tip with "Insert Coin" as the subject line.

Now that Google Glass and Oculus Rift have entered the zeitgeist, might we start to see VR and AR products popping up on every street corner? Perhaps, but Meta has just launched an interesting take on the concept by marrying see-through, stereoscopic, display glasses with a Kinect-style depth sensor. That opens up the possibility of putting virtual objects into the real world, letting you "pick up" a computer-generated 3D architectural model and spin it around in your hand, for instance, or gesture to control a virtual display appearing on an actual wall. To make it work, you connect a Windows PC to the device, which consists of a pair of 960 x 540 Epson displays embedded in the transparent glasses (with a detachable shade, as shown in the prototype above), and a depth sensor attached to the top. That lets the Meta 1 track your gestures, individual fingers and walls or other physical surfaces, all of which are processed in the PC with motion tracking tech to give the illusion of virtual objects anchored to the real world.

If you thought current media-darling Curiosity is where all the martian action is right now, think again. Its elder sibling, Opportunity, is still rolling up there too. In fact, it's just wheeled its way into a little page of NASA history: the longest distance one of its vehicles has traveled on a body beyond Earth. A recent short (by our standards) trip of 263 feet took its total to 22.22 miles covered on Mars' surface since landing in January 2004. The previous title holder was a Lunar Rover, part of the Apollo 17 mission over 40 years ago, that covered (if you hadn't guessed) 22.21 miles. Opportunity's not beat the world galaxy record though. That honor goes to the Soviet Lunokhod rover, which totted up a total of 23 lunar-based miles back in 1973. In relative terms, Curiosity's barely stretched its legs.

The Defense Department has officially given the thumbs up to Apple devices running iOS 6 -- paving the way for iPhones and iPads to become standard issue around the Pentagon. The move was hardly shocking. In fact, the Wall Street Journal had it on good authority weeks ago that the DoD was planning to give iOS its seal of approval. With Samsung devices running the Knox security suite and BlackBerry 10 already trickling into the hands of Pentagon employees, the decision sets the stage for a three-way bout for military market supremacy. And we're sure the government drones can't pick sides fast enough. After all, who wants to live under the tyranny of BlackBerry 7 any longer than necessary?

Remember Samsung's TecTiles NFC-enabled stickers? Well, much to our dismay, they don't work with the company's flashy new handset, and Galaxy S 4 owners haven't had an alternative to stock up on until today. Samsung's new TecTiles 2, which can perform tasks similar to the smartphone maker's previous-generation product, are now available, priced at $15 for a pack of five. They're compatible with all Samsung NFC-enabled Android smartphones, and offer up a variety of functions, such as muting your device when you tap a tag in the boardroom, or checking you in on Foursquare by touching a TecTile in a restaurant, for example. The small square stickers can now be ordered on Samsung's website -- if you'd prefer to pick them up in store, you'll need to hang tight until June.

NVIDIA newsletter subscribers have been able to pre-order the Shield handheld console for several days now, but the rest of us were due to wait until after the weekend. Considering that $349 price tag, we're not entirely sure we want to commit without having a chance to take the final hardware for a spin, but the option now exists nonetheless. Beginning today (instead of the previously announced date of May 20th), early adopters can hand over their cash at Gamestop, Newegg and Canada Computer, along with NVIDIA's own pre-order site, which we've linked for your convenience just below.

After months of supply issues and courtroom wrangling, HTC might have finally put its hardware woes behind it. The company's North Asian president, Jack Tong, let slip that production capacity for the HTC One will double this month and continue to increase in June to meet "strong demand." Tong also casually dropped into conversation that the J Butterfly saw its own sales double in Japan when it became free on contract -- so perhaps those second-quarter financial results won't make for such depressing reading.

According to co-CEO JK Shin, Samsung's Galaxy S 4 will soon hit the 10 million mark in sales, less than a month after its debut. That beats the Galaxy S III's time to that mark by nearly three weeks, making it far and away the company's quickest seller, ever. The model will also get another push thanks to a stock Android 4.2 version that'll be available for $649 at Google Play on June 26th, but so far it's an impressive figure, considering its bizarre reveal.
