Xiaomi showed the MiGu headband for controlling smart home devices with the power of thought.

There are three sensors on the headband that register brain signals and convert them into commands. The device can be used not only to control gadgets, but also to detect stress or fatigue while driving a car. The prototype was assembled by the company's employees as part of an annual developer forum dedicated to ideas that may be useful in the future. Not the fact that Xiaomi will undertake to finalize the project.
