Locus OS is a user interface concept for portable devices. It changes aspects of its UI based on the user's location.
The idea of organizing files into projects seems interesting. The movie doesn't show much of how this works - it seems users can either interact with their files in a spatial way, or using a timeline, but the timeline is never shown. Files do not seem to be associated with specific applications.
The system seems a bit disjointed, switching from a rich graphical user interface to a kind of text-based menu structure at one point. But it certainly contains some neat ideas.
Note that this is not actually a Microsoft project, despite of the logo in the movie.
