When meeting pre-determined distance condition apart from reference data in the present embodiment, in fact it could happen that a variety of situations, such as user is Through being worn by wearable device；For another example when other object distance wearable devices are closer；For another example having strong illumination to can When wearable device.Therefore, when whether distance reference data meet pre-determined distance condition, can not extremely accurate obtain can This state is centainly known as quasi- wearing state by wearable device in wearing state, the present embodiment, that is, is judged as at possible In wearing state.

Under quasi- wearing state state, wearable device can open operating mode, start corresponding detection function.It can wear Equipment is worn further by judging whether the angular velocity of satellite motion data meet preset angle threshold speed condition, to wearable device Wearing state corrected.If the wearing state of wearable device is corrected as non-wearing state by quasi- wearing state, immediately It is switched to standby mode from operating mode；If the wearing state of wearable device is corrected as wearing state by quasi- wearing state, Then continue to keep operating mode.

In general, handling distance reference data to judge that the speed ratio of wearing state is very fast, and handle angular velocity of satellite motion Data judge that the speed of wearing state is slow, if when the two judges that wearable device is in wearing state simultaneously, it can Wearable device restarts operating mode, it may appear that when user has just worn wearable device, since processing angular velocity of satellite motion data are sentenced The speed of disconnected wearing state is slow, and wearable device is still in standby mode；Wearable device is waited for handle movement Angular velocity data just opens operating mode when identifying in wearing state.This section of stand-by period can greatly influence to use The use at family reduces the usage experience of wearable device.
