Abstract
A control method for an electronic device comprising a sensor unit having a first detection range and a second detection range measured from the electronic device, and the second detection range being smaller than the first detection range. The method includes: detecting a 3D movement track of an operation body when the relative distance between the operation body and the electronic device is smaller than the first detection range, the 3D movement track being a continuous movement track having one end between the first and second detection range and the other end equal to or smaller than the second detection range; generating a status change signal when the operation body reaches close to or moves away from the second detection range of the sensor unit; executing a corresponding control command according to the 3D movement track and the status change signal.
