An electronic device is provided, which includes a fixing unit, a detection unit and a control unit. The fixing unit is adapted to maintain a position of the electronic device relative to a user when the user uses the electronic device. The detection unit is adapted to detect a spatial parameter of the electronic device being moved in a space. The control unit is adapted to obtain the spatial parameter, determine whether the spatial parameter matches a predetermined parameter condition, and control the electronic device to switch from a first operation mode to a second operation mode when the spatial parameter matches the predetermined parameter condition, wherein the first operation mode is different from the second operation mode.
