Identification module 400 is the most unidentified in the case of gesture motion, has recognized first gesture action,
Then explanation user needs to use gesture recognition module 400 to be controlled, then in gesture recognition module 400
Waken up up when descending in a dormant state, and make gesture recognition module 400 keep detection state 15 seconds,
When gesture recognition module 400 is in detection state, again gesture recognition module 400 is kept detection
State 15 seconds.
In technique scheme, when recognizing first gesture action, illustrate that user needs to use hands
Gesture identification module 400, then gesture recognition module 400 in a dormant state time, by gesture identification mould
Block 400 wakes up up, it is to avoid in correlation technique when receiving infrared reflectance signal just by gesture identification mould
Block 400 wakes up up, thus reduces the maloperation to gesture recognition module 400.Such as, window is blown when wind
When curtain makes the detection region that curtain enters into gesture recognition module 400, though gesture recognition module 400
Have received infrared reflectance signal, actually user is not required to use gesture recognition module 400, this
Time gesture recognition module 400 is not waken up up.
It addition, when recognizing first gesture action, illustrate that user needs to use gesture recognition module
400, no matter gesture recognition module 400 is in detection state or resting state, all makes gesture identification
Module 400 keeps first scheduled time of detection state (such as 15 seconds), so that user has enough
Time carries out gesture motion.Such as, even if only remaining in gesture recognition module 400 and having switch to for 3 seconds
During resting state, if having recognized first gesture action, now by the detection of gesture recognition module 400
Gesture recognition module 400 is switched to not after being re-set as 15 seconds, 15 seconds by the time of state again
Dormancy state, it is to avoid user has not carried out gesture motion in remaining 3 seconds and advanced to dormancy shape
State and cause the inaccurate of gesture identification.
Wherein, when gesture recognition module 400 in the dormant state time, gesture recognition module 400 is in
The state of low-power consumption, so that it can recognize gesture motion.Such as, gesture recognition module 400
The transmitting power of infrared transmitting tube and tranmitting frequency ratio are relatively low.
