FIELD: physics.
SUBSTANCE: method includes: determining the current state of the terminal screen as the first state; forming the first electromagnetic signal, corresponding to the first state, and transferring the first electromagnetic signal on the metal part through the first component connection using the human body, so that the first electromagnetic signal passes through the skin of the user; receiving the first component connection using the human body through the metal part of the second electromagnetic signal that is returned in response to the first electromagnetic signal associated with the portable device, and if the second electromagnetic signal contains information about switching the terminal screen state, switching the current state of the first state to the second state.
EFFECT: providing quick control of switching the screen lock state of the terminal, improving safety and reducing power consumption.
