Mixed reality devices like the Hololens open up a new realm of possibilities in terms of user interfaces and user experience. Today, we mainly find game-like experiences or ports of a 2D user interface in a 3D space, but with more time in the device, our group discovered options that make much better use of this space. From our own research and experience in working on practical applications in mixed reality, we explore what we’ve learned and user experience processes we’ve adapted to create new and meaningful user interfaces that take better advantage of the medium.
