Samsung tackles sport safety with development of concussion monitoring Brainband

Samsung Brainband sends concussion warnings to linked devices
Fresh from launching a virtual reality device last year and a new suite of phones just a few weeks ago, Samsung today launched Brainband, a headband that registers a dangerous hit for a sports competitor in real time.
Samsung chief marketing officer, Phillip Newton, said that the Australian initiative was part of Samsung’s global launching people project.
The device registers when a player takes a heavy hit to the head and records the level of G-force impact, before relaying a warning to other devices, including the G2 watch, being worn by the referee, who can then make a decision as to whether the player needs to leave the game.
Is this a real thing or a prototype?
