When you're seriously shredding on your semi-dangerous vehicle of choice (bike, motorbike, personal jetpack, electric unicycle) and you need to capture some of your "moves," you're going to be reaching for something like the VholdR. Well, you probably won't be reaching for it, since Twenty20 says this is "wearable," and though it looks similar to the company's helmet camera, we think you're supposed to put it somewhere else. Regardless -- you'll at least be reaching for the record button... er, switch. The small camera will supposedly capture all your freshest moments with its 192 degree rotating lens, twin laser alignment, "fine line" compression engine, and shockproof, splashproof aluminum enclosure. Finally, a device which is equally matched to your daredevil-like, extreme lifestyle. Available during "the holiday season" for $349.99, and ready for preorders right now.

No question about it, strapping a webcam to your dome or rocking a set of unsightly head-mounted displays can kill a substantial amount of time, but researchers from the University of Bristol are looking at more practical uses of wearable cameras. A shoulder-mounted camera system that "automatically tracks head movements and can recognize hand gestures" has been developed in the UK, and eventually, they hope for it to recognize what the user is doing and make his / her life easier by communicating with other devices based on their actions. The cam is controlled wirelessly by a host computer, which "uses the camera's output to keep track of objects, map its position and recognize different hand gestures made by the user." Interestingly, the perched device even includes a trio of motors for muti-directional assistance, and built-in inertia sensors keep it level with the dips and dodges of life. Of course, we can't promise you that everyone (like mall security) will take kindly to a Big Brother-type device flanked on your shoulder, but at least you won't have to hire a bodyguard to watch your back, right?
