Wearable devices and 4K are two of the biggest trends at CES, and Panasonic has managed to make both collide. The outfit's revealed a UHD camera that folks can wear on their head with the help of a plastic mount that wraps around their ears and neck. While the prototype is nearly identical to the HX-A100 cam the firm debuted at last year's show (yes, it's still waterproof), this Ultra High-Definition model is lined with some more powerful innards. Detailed tech specs are being kept under lock and key, but the unit on display was sending a live feed of the pixel-packed footage to a 4K display through a mini-HDMI port -- a feature that will be available in the final version. Despite the hardware's compact form, it produced sharp video free of stuttering, and caught a fairly wide field of view courtesy of its fisheye lens. While there's no word on pricing, the first-person camera is slated for a release later this year.
