Control Method for Terminal, Terminal, Intelligent Wearable Device, and System

A terminal, in a bound state with an intelligent wearable device, comprising:

• input circuit configured to receive, in a lock screen state of the terminal, a state switching instruction indicating the terminal to switch state;
• and
• a processor coupled to the input circuit and configured to:
• send, using a communications interface, a motion data obtaining request to the intelligent wearable device;
• receive, using the communications interface, first motion data of the intelligent wearable device within a predetermined time;
• detect, using a motion sensor, a motion state of the terminal to obtain second motion data of the terminal within the predetermined time period;
• obtain the second motion data of the terminal within the predetermined time period;
• calculate a deviation between the first motion data and the second motion data;
• and
• switch a stale of the terminal when the deviation is less than a deviation threshold.

An intelligent wearable device, comprising:

• a communications interface, configured to receive a motion data obtaining request from a terminal m a bound state with the intelligent wearable device;
• a processor, coupled to the communication interface and configured to:
• detect, using a motion sensor, a motion state of the intelligent wearable device, to obtain first motion data of the intelligent wearable device within a predetermined time periods;
• and
• instruct the communications interface to send the first motion data to the terminal, and
• the communications interface being further configured to send the first motion data of the intelligent wearable device to the terminal.
