Passthrough API Experimental—a way to build and test apps that seamlessly blend the real and virtual worlds and open up new possibilities for mixed reality experiences. Available in our upcoming v31 SDK release, Passthrough API Experimental will allow you to create new experiences for: Productivity: Enable users to collaborate with a remote team of co-workers or friends through virtual monitors, while accessing their physical keyboard and desk. Gaming: Create games that blend the excitement of a virtual world into the comfort and familiarity of the real world, like zombies hiding in your living room. Co-located Social Presence: Allow users to be both engaged in your virtual content and able to interact with people and pets in the same room, at the same time.
