There has been much done and said about the applications of Virtual Reality, including multi-user scenarios. Indeed, this speaker and his 1980’s startup pioneered many of the familiar app categories, including surgical simulation, vehicle prototyping, interior design, and so on. It’s taken a long time and lot of effort, but now that appropriate devices such as HoloLens are available, apps for Mixed Reality are finally in broad development. These include facilities management, field documentation/training, and on-site design and prototyping. But what about social mixed reality? In that case, applications research is less well known. Some of the examples explored so far - leaving entertainment aside - are rather surprising; they include chronic pain management, collaborative explorations of mathematical expressions, and novel and innovative approaches to manufacturing, healthcare & medical devices, product design, and more. Meanwhile, fundamental research is still needed to realize some of the “obvious” applications that are often desired, including full duplex telepresence. Early experiments in social mixed reality have indicated that it has its own emotional palate, freshening the way people perceive each other.
