Microsoft Hololens 2: I use one for work, and it's absolutely incredible. It's an augmented reality headset with built-in hand tracking, so you interact with the holograms by touching them with your hands. You mentioned "Tony Stark" technology, and it really is like the hologram computer he uses. When you look down at your hands, you see a Windows logo appears on your wrist (it follows your wrist due to the hand tracking). When you tap on the Windows icon on your wrist, a start menu appears in front of you, and you can choose an AR app to launch by tapping it with your finger. These apps can be full 3D experiences (like ones created with Unity) or they can be 2D apps where you can place 2D windows around you (like the built-in Edge browser app). These headsets are over $3K, so they're currently used for high-end niche use cases that justify that investment. For example, some of my customers use them to show 3D instructions to technicians for aerospace manufacturing. However, from using the Hololens 2, it's clear to me that AR will inevitably become a major computing platform once the price is reduced. My guess is that we will start to see that in 6 - 10 years.
