The invention discloses a method and a device for control. The method and the device are applied in an electronic device with a flexible structure. The method comprises: monitoring a first application that the electronic device operates at present; at least based on the first application, determining a deformation parameter; and according to the deformation parameter, controlling the electronic device to have first deformation, so that the shape of the electronic device after first deformation is matched with the first application. The method is different from the prior art that in the prior art, a characteristic that durability and damage rate of the electronic device in a flexible structure are low is used. The method uses the characteristic that the electronic device in the flexible structure can deform, and the electronic device is controlled to deform so that the electronic device has certain matching relations with the first application which is operating at present. Thus, the flexibility characteristic of the electronic device is better developed, and utilization rate of the electronic device with the flexible structure is improved.
