Following Fan / Electric Fan

The traditional fan swings within a fixed angle with constant speed. During this process, there is an unnecessary waste of energy. The following fan deals with this problem with some existing technique, inspired by the sunflower. The fan direction keeps following the user by technique of infrared tracking. This will maximize the effect of blowing and energy. At the same time, it gives the user a new experience. If there is just one user, the fan follows him. If there are several users, the fan swings within them.
