Abstract
By blending physical and virtual worlds, Mixed Reality (MR) is unlocking exciting new experiences and generating new paradigms in both social and professional interactions. Powered by continual advances in computer vision, graphical processing power, display technology, and input systems, MR is strengthening interactions between humans, their environment, and computers and enabling endless new opportunities. To enable a seamless and immersive experience, an MR device is a complex system, comprising of multiple optical, electrical, mechanical and computational sub-systems. Inputs from various user and environment sensors (i.e. head/eye/gesture tracking, depth scanners, etc.) are synthesized and fused with virtual content that is then projected to the user via the display subsystem. Providing a seamlessly integrated experience requires engineering a display around limitations of both optical system design, as well as that of the human visual system. After a brief introduction to Mixed Reality, this talk will aim to provide an overview of a typical MR display system, outline some of the key design parameters and constraints, and provide a few examples of navigating the trade-offs involved.
