There are a few reasons that this is really interesting.
First is that a museum tour kind of application with PicoP was one example cited years ago to stockholders. That the museum's displays could be projected onto a blank wall, and someone who isn't there could experience the exhibit.
Second, this is a use of AR that is already going mainstream.
Thirdly, it's gathering data so that when AR is implemented with glasses, there will be an ecosystem for it to land in -- it will be immediately useful.
