The Hololens（全息眼镜）
The Hololens has unbelievable computing power, a lot of sensors, and high - definition（高分辨率的） cameras. Users who wear the glasses see the real scene（场景） and the virtual（虚拟的） scene fit together, and they can control the virtual scene. Scientists can work on the lab bench as if they were there when they study Mars.
