HoloLens is essentially a holographic computer built into a headset that lets you see, hear, and interact with holograms within an environment such as a living room or an office space.

Mixed reality brings people, places, and objects from your physical and digital worlds together. This blended environment becomes your canvas, where you can create and enjoy a wide range of experiences. Interacting with holograms in mixed reality enables you to visualize and work with your digital content as part of your real world. Holograms are responsive to you and the world around you. Microsoft HoloLens enables you to interact with content and information in the most natural ways possible. Built-in sensors let you use your gaze to move the cursor so you can select holograms. Turn your head and the cursor will follow. Use simple gestures to open apps, select and size items, and drag and drop holograms in your world. Use voice commands to navigate, select, open, command, and control your apps. Speak directly to Cortana, who can help you complete tasks. Transform the ways you communicate, create, collaborate, and explore. Your ideas are closer to becoming real when you can create and work with holograms in relation to the world around you.
