It’s a little shocking to think about the impact that Microsoft’s Kinect camera has had on the gaming industry at large, let alone the 3D modeling industry. Here at SIGGRAPH 2011, we attended a KinectFusion research talk hosted by Microsoft, where a fascinating new look at real-time 3D reconstruction was detailed. To better appreciate what’s happening here, we’d actually encourage you to hop back and have a gander at our hands-on with PrimeSense’s raw motion sensing hardware from GDC 2010 — for those who’ve forgotten, that very hardware was finally outed as the guts behind what consumers simply know as “Kinect.” The breakthrough wasn’t in how it allowed gamers to control common software titles sans a joystick — the breakthrough was the price. The Kinect took 3D sensing to the mainstream, and moreover, allowed researchers to pick up a commodity product and go absolutely nuts. Turns out, that’s precisely what a smattering of highly intelligent blokes in the UK have done, and they’ve built a new method for reconstructing 3D scenes (read: real-life) in real-time by using a simple Xbox 360 peripheral.

The actual technobabble ran deep — not shocking given the academic nature of the conference — but the demos shown were nothing short of jaw-dropping. There’s no question that this methodology could be used to spark the next generation of gaming interaction and augmented reality, taking a user’s surroundings and making it a live part of the experience. Moreover, game design could be significantly impacted, with live scenes able to be acted out and stored in real-time rather than having to build something frame by frame within an application. According to the presenter, the tech that’s been created here can “extract surface geometry in real-time,” right down to the millimeter level. Of course, the Kinect’s camera and abilities are relatively limited when it comes to resolution; you won’t be building 1080p scenes with a $150 camera, but as CPUs and GPUs become more powerful, there’s nothing stopping this from scaling with the future. Have a peek at the links below if you’re interested in diving deeper — don’t be shocked if you can’t find the exit, though.

What can’t graphene do? The wonder material’s been at the heart of a stunning number of technological breakthroughs of late, and now it’s adding oil exploration to its long list of achievements. A team of researchers at Rensselaer Polytechnic Institute have discovered that the flow of good old H₂O over a sheet of graphene can generate enough electricity to power “tiny sensors” used in tracking down oil deposits. The gang, led by professor Nikhil Koratkar, was able to suck 85 nanowatts of power out of a slab of graphene measuring .03 by .015 millimeters. The little sensors the researchers speak of are pumped into potential oil wells via a stream of water, and are then put to work sniffing out hydrocarbons indicative of hidden pockets of oil and natural gas. Of course, that doesn’t have a whole lot of practical application for your average gadget consumer, but Koraktar sees a future filled with tiny water-powered robots and micro-submarines — we can dig it.

Microbial fuel cells aren’t exactly new, but microbial fuel cells scouring the ocean floor? Now that’s an initiative we can get behind. The Naval Research Laboratory is currently toying around with a so-called Zero Power Ballast Control off the coast of Thailand, presumably looking for treasures dropped from the speedboat of one “Alan Garner.” Purportedly, the newfangled hydrogen fuel cell relies on bacteria to provide variable buoyancy, which allows an autonomous ocean sensor to move up and down water columns with little to no effort. Furthermore, it’s able to get its energy from microbial metabolism (yeah, we’re talking about hot air), and while it’s mostly being used to measure things like temperature and pressure, it could be repurposed for more seirous tasks — like mine detection. There’s no clear word yet on when America’s Navy will have access to this stuff, but if we had to guess, they’ve probably be using it behind our backs for the better part of a score.
