On its official Weibo account, Xiaomi announced that MiGu was the winner of its third online Hackathon. It’s a wearable device that acts like a headband and allows you to control your smart house system via brainwaves. Three sensors are included in the Xiaomi MiGu model. They record electrical signals from the brain. The potential difference between the sensors can be used to determine the approximate electroencephalogram of the wearer.
EEG curves can take many forms depending on the emotional state of a person. Xiaomi MiGu can recognize these and analyze them. This allows the headband to not only control the smart home via the “power of thoughts”, but also tracks the user’s fatigue while driving, for instance. This feature will prevent driver fatigue-related accidents. It is unclear if this device will be commercially released in the near future.
