Panasonic Corporation unveiled a product that combines two big tech trends - ultra HD and wearable devices- with a portable, camera that hooks onto one ear and records in ultra-high definition 4K video. Panasonic didn't immediately name the gadget, but it resembles the company's A100 full HD camcorder, which is a smartphone-sized device that straps to a user's arm and is connected by a cable to a tubular device housing the lens. The device is waterproof and dust-proof and for the everyday person.

Video shot in 4K resolution, which uses about quadruple the pixels found in HD, can be shared via Wi-Fi and viewed on smartphones or ultra HD living room TVs.
