Not sure if this falls under robotics or home automation? I have an idea to use an Arduino to control the direction in which a table fan blows air. The thought was first to use PIR to locate me and aim the fan in my direction as I moved but decided that would be too imprecise and would be confused …

Fan that knows where you are?

The first issue to solve is how will you be detected. It is not so easy.
