Last year Microsoft released the Hololens developer editions. Since then there has been a lot of excitement around the VR and AR platforms. Unlike the Vive and Oculus, the Hololens is holographic, and all of the processing is on the device! The hololens has some interesting features! You can interact with the holographic world with gaze and hand gestures, as well as speak commands. One of the most unique features of the hololens is the spatial mapping and the spatial sound. These features make the device an immersive experience, but are really easy to get started with! In this talk I will introduce the hololens and show how to build a simple real world application with it that uses these features. We will have a few hololenses for you to try out as well!
