Meet the Fly Jacket: a smart jacket designed to help drone pilots control their drone with body movement. Developed by EPFL researchers, this jacket lets drone pilots lean forward/backward and pivot their body to control their drone. It also keep their hands free, so data gloves can be used for additional drone commands.
The jacket uses motion sensors developed by EPFL Laboratory of Embedded system for responsive control. The above videos give you a better idea how it works.
