Abstract

An air gesture recognition type electronic device operating method for operating an electronic device having multiple sensors in each of multiple peripheral sides thereof by: approaching an object to the sensors to produce sensing signals and determining whether or not the object has been continuously sensed, and then determining whether or not the moving direction and moving speed of the object match a respective predetermined value, and then coupling and computing all received sensing signals to produce an operating parameter for running an air gesture application procedure. Thus, a user can operate the electronic device without direct contact or the use of any camera or input media, saving the hardware cost and enhancing the operational flexibility.
