Hasta La Gadget!

A virtual touchpad projected onto limbs and other everyday surfaces? That’s the type of crazy idea we’d normally expect to see from Microsoft Research, not Google. Heck, maybe we even did, but Google is now applying to patent the concept specifically in relation to Project Glass. The system would use a tiny laser projector mounted on the arm of the spectacles to beam out QWERTY and other buttons, and then the built-in camera and processor would try to interpret finger movements in the region of those buttons. Hey presto! No more fiddling with your face.

Magnetic levitation is central to the fastest trains we know today, but it’s that dependence on electromagnets and rails that limits how and where it’s used for transportation. Aoyama Gakuin University has a unique alternative: changing the material properties themselves. By floating graphite over a bed of circular magnets, taking advantage of its tendency to generate an opposing magnetic field, researchers can move the graphite just by blasting its edge with a laser. The heat skews the magnetic behavior of that area enough to unbalance the graphite, either in a specific direction or a spin. The research team believes it could lead to maglev transportation or even energy converting turbines that are steered solely by light, with no contact or outside guides: maglev vehicle pilots could have much more control over where they go. Getting to that point will require a much larger scale, but successful development could give technology a very literal lift.

As LG continues its slew of CES 2013 pre-announcements, the latest is a new display technology it’s bringing to the projection arena, an ultra short throw laser projector. Capable of creating a 100-inch screen from just 22 inches (56cm) away, the “Hecto” Laser TV a 1080p shooter that can change the way owners design their home theater. If you’d like to use it as an all-in-one home theater to go (the screen is included, picture after the break), it also has a digital tuner and 10w speakers built-in, with three HDMI inputs, an RS-232 port and Smart TV capabilities controlled by LG’s Magic Remote. As you can see above, it follows LG’s “Dynamic Arc Design” with a max height of just 5.7-inches. It carries a 1,000,000 to 1 contrast ratio with WiDi and Miracast compatibility and LG claims the laser system will run for up to 25,000 hours without replacement. There’s no word on pricing or release date, although it likely won’t be value priced. We expect to get a few more details when we see it in Las Vegas, check the press release after the break for all the information currently available.

It’s not that often we see the worlds of baking and technology mix, but when Johan von Konow went about making a traditional gingerbread house for the holidays, he added a laser to the recipe. The engineer and tinkerer first went about designing an accurate, miniature 3D representation of his summer house in a CAD program, with the help of his wife. He then printed outlines of the necessary building blocks onto sheets of baked gingerbread, and used a 50-watt laser engraver to cut them out and score icing guides for the final touches later on. Burnt edges rendered the confectionary inedible, but as its final destination was no longer stomachs, raw lasagna sheets were added for structural support, and hot glue used to bind it all together. If you’ve got all the kit and are feeling inspired by the picture above, the design layout and project walkthrough are available at the source link below. Hansel and Gretel needn’t be worried this time around — the tech used creating this particular gingerbread house has attracted a different kind of aged tenant.

Thousands of people lose their lives each year to car accidents. The sad thing is some of these deaths could have been prevented, had they taken more care when crossing the road. We can only do so much by raising awareness. The second step is coming up with a system to force people to be aware of their surroundings, so they will only actually attempt to cross the road when it’s safe. That’s where the Guardian comes into play.

Ho-Joon Lim’s simple, but smart concept uses laser lights to guide people on their short walk across the street. It also works effectively to keep people off the streets and on the sidewalk when it’s not time to cross the road yet.

The only real challenge with the design is that you need some sort of fog or smoke in the air to make low-power laser beams visible – especially in daylight. So unless you live in a really foggy city, or the design incorporates a smoke machine, it might not be too practical.
