I can think of few real world applications. Eg. I have autism and air filter. Air filter working on full power is very uncomfortable for me, but with position sensing, it can be configured to run more often when I'm not in room. Motion sensing isn't exactly a solution, because I can be very still.

Automated light management is sensible too. It can also be used to automatically turn off lights if I fall asleep.
