The method includes several steps: first, using millimeter wave radar to obtain the point cloud height of center of gravity for azimuth data points; next, evaluating whether the detected movement qualifies as a half getting-up action; subsequently determining if it is a full getting-up action; and finally, controlling the lamp accordingly—if a half getting-up action is detected, the lamp operates in a first state, and if a full getting-up action is detected, in a second state. This approach links lamp operation to the user's physical actions, enhancing functionality and user experience.
