Praying mantises get extra-tiny 3D glasses to test their vision
While 3D video may not be very popular these days, someone's still wearing 3D glasses -- or rather, something. Newcastle University scientists are outfitting praying mantises with very small 3D eyewear to test their depth perception, which is unique in the insect world; most species are limited to 2D. The researchers want to see if the bugs are fooled by the effects of a 3D movie like that you'd see in a theater. If they are, we'll know that they evolved 3D vision similar to that of humans and monkeys.
Kinect used to make teleconferencing actually kind of cool (video)
No matter how hard Skype and others try to convince us otherwise, we still do most of our web communications via text or, if entirely unavoidable, by voice. Maybe we're luddites or maybe video calling has yet to prove its value. Hoping to reverse such archaic views, researchers at the MIT Media Lab have harnessed a Kinect's powers of depth and human perception to provide some newfangled videoconferencing functionality. First up, you can blur out everything on screen but the speaker to keep focus where it needs to be. Then, if you want to get fancier, you can freeze a frame of yourself in the still-moving video feed for when you need to do something off-camera, and to finish things off, you can even drop some 3D-aware augmented reality on your viewers. It's all a little unrefined at the moment, but the ideas are there and well worth seeing. Jump past the break to do just that.
Ball-throwing robot seal has a talent for basketball, embarrassing humans (video)
You pick up your first tan leather roundball at the age of 9, you practice religiously for a decade before you can even feel worthy of calling yourself a basketball player, and then you find a video online of a robotic seal that can shoot better than you after just a few weeks in the lab. Yep, some Taiwanese know-it-alls have put together a robo-seal that converts 99 percent of shots (admittedly with a toy ball launched at a toy hoop) within a three-meter range. It's basically just an articulating arm with stereo vision for some good old depth perception, but it's sophisticated enough to maintain its killer accuracy even if the target is moved from its spot. That's more lethal that Shaq or Karl Malone's elbows ever were. Video's after the break, skip to the 1:05 mark if you don't care about the details of how it's done.
