    Abstract: An interface operating control device applied in an electronic device with an interface includes a sensing module, a recognizing module, a bottom layer executing module, and an operating module. The sensing module outputs sensing signal when a distance between the object and the interface is less than a preset distance. The recognizing module receives the sensing signal and acquires operating characteristics of the object according the sensing signal. The bottom layer executing module boots an application mode corresponding to the operating characteristics acquired currently. The operating module determines different intensity applied on the interface by the object according to total areas touching on the interface, and executes different operation instructions of the application mode currently operating according to the different intensity. Therefore, a system of the electronic device can be accessed rapidly and conveniently, and the users can get abundant operations and experiences.
