HoloLens 2 : A new generation of holographic computing

Microsoft HoloLens, known under development as Project Baraboo, is a pair of mixed reality smartglasses developed and manufactured by Microsoft. HoloLens was one of the first computers running the Windows Mixed Reality platform under the Windows 10 operating system. The HoloLens can trace its lineage to Kinect, an add-on for Microsoft's Xbox gaming console that was introduced in 2010.
The first HoloLens headset ushered in the concept of mixed reality, a form of augmented reality that mixes the real world with virtual objects. It’s a pair of smart glasses rather than a full-blown headset, but it was still a chunky device.
The second-generation HoloLens, is here, known as HoloLens 2 with an upgrade to its previous model.

Work smarter with the ultimate mixed reality device

Elevate understanding. Stay present. Make better decisions.

HoloLens 2 offers the most comfortable and immersive mixed reality experience available, with industry-leading solutions that deliver value in minutes—all enhanced by the reliability, security, and scalability of cloud and AI services from Microsoft.

See more holograms at once through the greatly increased field of view. Read the text and see intricate details on 3D images more easily and comfortably with industry-leading resolution.

Wear HoloLens 2 longer and more comfortable with a dial-in fit system designed for extended use. And keep your glasses on—the headset slides right over them. When it's time to switch tasks, flip the visor up to step out of mixed reality.

Touch, grasp, and move holograms in ways that feel natural—they respond a lot like real objects. Log in to HoloLens 2 instantly and securely using just your eyes with Windows Hello. And voice commands work even in noisy industrial environments through smart microphones and natural language speech processing.

Move freely, with no wires or external packs to get in your way. The HoloLens 2 headset is a self-contained computer with Wi-Fi connectivity, which means that everything you need goes with you while you work.
