Virtual reality goes magnetic

The success of Pokémon GO made many people familiar with the concept of 'augmented reality': computer-generated perception blends into the real and virtual worlds. So far, these apps largely used optical methods for motion detection. Physicists have now developed an ultrathin electronic magnetic sensor that can be worn on skin. Just by interacting with magnetic fields, the device enables a touchless manipulation of virtual and physical objects. https://www.sciencedaily.com/releases/2018/01/180119190403.htm
