The best use case i can see for a device like this a hands free recording and support for law enforcement, rescue and emergency teams.
Imagine a paramedic recording all the info about the victim of a car accident and being able to project relevant information or questions on the asphalt or any other surface at night. The rescue crew would have both hands free to stabilize the victim, maybe even get the victim's medical history without having to stop everything to type on a smartphone or tablet.
