Multiply and subtract your way to more lifelike VR avatars

POSTECH's (Pohang University of Science and Technology) Professor Inseok Hwang's team has developed ArithMotion, a mobile virtual reality (VR) system that enables anyone to express a wide range of avatar motions with ease. Using simple arithmetic-like controls, users can scale an avatar's motion up or down and reverse it into an opposite response, allowing more natural nonverbal communication without expensive equipment.
