Augmented Reality has been getting ready for the last 20 years, and is finally becoming real, powered by progress in enabling technologies such as graphics, vision, sensors, and displays. In this talk I’ll provide a personal retrospective on my journey, working on all those enablers, getting ready for the coming AR revolution. At Meta, we are working on immersive optical-see-through AR headset, as well as the full software stack. We’ll discuss the differences of optical vs. video see-through displays, immersion, Meta 2 optics, and the key computer vision enablers for AR. We will finish with discussing the many possible applications that are enabled by wearable and immersive Augmented Reality.
