At the beginning of the year, Samsung showed off a few of its employees' experimental products at CES 2016 under the company's Creative Lab, or C-Lab, program. That included a smart belt, a smart wristband, and a virtual reality "handle bar" controller. At SXSW, the company revealed a few more ideas that, if turned into actual products, could be pretty interesting. For example, the Hum On! app can turn any hum or voiced tones into a musical piece. Waffle makes social networking an even more social and collaborative process, while Entrim 4D gives VR users a sense motion delivered through their ears.
