To ensure that the target person remains cool at all times, the fan will align itself to the pattern which it will recognize using said camera. Whenever it fails to detect a particular pattern, it will just “look around” in a random manner, hence keeping the room cool at the same time. The moment it finds what it is looking for, it will lock down onto its target.
Needless to say, those patterns can also be used to offer control for various basic functions, and with the help of gestures, you too are able to control fan position, speed, and even turn it on and off. A button-free future does seem to be in the works, no?
