Newest Kinect hack: a grocery cart that loyally follows disabled shoppers (video)

Microsoft’s Kinect is the gift that keeps on giving for hackers, spawning everything from glasses-free teleconferencing to Tesla coil manipulation to uh, well, Android dance parties. But Luis de Matos’s wi-Go project is one of the most socially conscious we’ve seen: it adds a laptop and (despite its name) a Kinect to a shopping cart, enabling the cart to follow a wheelchair user. Improving on the B.O.S.S. bot we saw a half-decade ago, the wi-Go could allow anyone — including the disabled or elderly — to shop independently, regardless of physical capability. De Matos doesn’t offer many technical details, but see the video above for a before-and-after demonstration.

Stats Show iPhone Owners Get More Sex

Gadget lovers have long held to the secret belief that the right camera, smartphone or large-aperture lens will make them sexier.

Now dating site OK Cupid has proof.

According to OK Cupid’s survey of 552,000 user pictures, digital SLRs make you look more attractive, Panasonic cameras make you sexier than Nikons, while using a flash will make you look 7 years older, and large-aperture lenses make you hotter.

And iPhone users have more sexual partners than BlackBerry or Android owners. By age 30, the average male iPhone user has had about 10 partners while female iPhone users have had 12. By contrast, BlackBerry users hover around 8 partners and Android users have a mere 6.

As the blog’s author’s wryly observe: “Finally, statistical proof that iPhone users aren’t just getting fucked by Apple.”

That should give iPhone and iPad users some comfort for being considered ‘selfish elites,’ as another recent survey found.

OK Cupid has been analyzing the behavior of the site’s millions of users for some time, and has discovered many interesting tidbits: People tend to lie on their profiles, people’s political preferences change as they age, and men can increase their chances of getting a date by being open to older women. The site’s massive dataset, huge volume of activity, and interesting slicing and dicing combine to produce some keen observations on human nature.

But for gadget heads, there’s no more pertinent observation than (hard) data. The Panasonic Micro 4/3 camera will make you look far more attractive than a Canon DSLR, which in turn is better than a Nikon or Sony DSLR. And forget about cameraphones: Android, Nokia, BlackBerry and Windows phones all make you look less attractive, with Motorola phones at the absolute bottom of the list.

Similarly, the type of camera you wield makes a big difference. There’s a dramatic illustration showing how the same woman looks photographed with a cameraphone, a point-and-shoot camera, and an SLR. That makes sense: As we’ve explained before, larger image sensors give you better-quality images.

Along the same lines, a larger-aperture photo lets you put the background out of focus, increasing the apparent attractiveness of the person you’re taking a picture of.

So if you wanted an excuse to buy a fancier camera with a bigger lens, OK Cupid’s got all the rationale you need.

As for switching from Android or BlackBerry to an iPhone? Well, that’s up to you. Unlike with the photos, it’s hard to tell whether iPhone use is the cause, or the effect, of having more notches in one’s bedpost.

Helmet radar: coming to a supersoldier near you

A helmet-mounted radar unit seems redundant with the kind of crazy surveillance and intel they already have available or in the pipes, but hey, whatever helps our boys. While satellite and air-based imaging are invaluable to the modern field commander, an individual infantryman has little feedback in an more local tactical situation. So why not have an imaging system for individuals?

The Helmet Mounted Radar System (HMRS) is “a miniature, low power, near 360-degree field of view Moving Target Indicator (MTI) radar sensor that will alert the soldier to the whereabouts of a target out to at least 25 meters.” 25m isn’t very far, but providing even a hint of a nearby enemy could be the difference between life and death. The only trouble, it seems to me, is that the modern soldier is going to be so weighed down with all the gadgets and armor made to save his life that he won’t be able to maneuver.

Not to mention, this may lead to extremely scary moments like that part in Alien where the guy is in the tunnels and IT’S RIGHT BEHIND YOU AAAAAARGH

NC State gurus develop new material to boost data storage, conserve energy

We’ve all assumed that anything’s possible when dabbling in the elusive realm of spintronics, and it seems as if a team at NC State University is out to prove just that. While using their newfound free time on Saturdays (you know, given that the football team has quit mid-season), Dr. Jagdish Narayan and company have utilized the process of selective doping in order to construct a new type of metallic ceramic that could be used to create a “fingernail-size computer chip to store the equivalent of 20 high-definition DVDs or 250 million pages of text.” The material could also be used (in theory, anyway) to create a new generation of ceramic engines that could withstand twice the heat of normal engines and hit MPG ratings of 80. Granted, this all sounds like wishful thinking at the moment, but we wouldn’t put it past the whiz kids in Raleigh to bring this stuff to market. Too bad the athletic director doesn’t posses the same type of initiative.

[Thanks, Joel]

Optogenetics hold the key to future brain disease cures, still creep us out

Those mad neuroscientists, they’ll never learn, but maybe in the end we’ll all be better off for it. Wired has put together an extremely intriguing write-up of the short history of optogenetics — featuring a German pond scum researcher, a Nobel Prize winner, and rat brains controlled by beams of light. Optogenetics is a relatively new technique for communicating with the brain, which involves the implantation of particular light-sensitive genes into animals with the purpose of repairing neurological ailments through light therapy (no, not that kind). By hooking up fiber-optic cables to the affected area of the brain, researchers have been able to completely restore movement in mice with Parkinson’s disease and their current efforts revolve around developing a less invasive method that doesn’t go deeper than the outer surface of the brain. Most revolutionary of all, perhaps, is the eventual possibility for two-way traffic (i.e. a machine being able to both send and receive information from the brain), which brings all those cyborg dreams of ours closer to becoming a reality than ever before. Hit up the read link for the full dish.
