To determine the moving direction of the gesture that user makees before projection lens as from top to bottom again up.First direction in Fig. 2 be from
On down, second direction is from the bottom up.
For example, the moving direction of gesture, as shown in Figure 2.Due to generally during gesture is moved up and down, moving from top to bottom
Dynamic amplitude has certain difference with amplitude from the bottom up, it is assumed that the displacement that gesture is moved from the bottom up is a, under
The displacement up moved is b, process of the gesture detection module 200 in the corresponding gesture amount of movement of gesture for calculating user
In, the two displacements can be compared, and regard maximum of which displacement as gesture amount of movement.Assuming that mobile
It is less than displacement b apart from a, then regard displacement b as gesture amount of movement.
S502, judges whether gesture meets preparatory condition according to gesture parameter.
Specifically, after gesture parameter is generated according to gesture, if gesture parameter is gesture amount of movement, it can determine whether that gesture is moved
Whether momentum is less than or equal to pre-determined distance threshold value, if gesture amount of movement is less than or equal to pre-determined distance threshold value, judges hand
Gesture meets preparatory condition.
In addition, if gesture parameter be gesture movement after dwell time when, can determine whether gesture movement after dwell time whether be more than
Or equal to the first preset time threshold, if dwell time is more than or equal to the first preset time threshold after gesture movement, sentence
The gesture of disconnected user meets preparatory condition.
According to gesture generate gesture parameter after, if gesture parameter be gesture amount of movement and gesture movement after dwell time when,
It can first judge whether gesture amount of movement is less than or equal to pre-determined distance threshold value, if gesture amount of movement is less than or equal to pre-determined distance
Threshold value, then determine whether whether dwell time is more than or equal to the first preset time threshold after gesture movement, if gesture is moved
Momentum is less than or equal to dwell time after pre-determined distance threshold value, and gesture movement and is more than or equal to the first preset time threshold, then
Judge that gesture meets preparatory condition, that is, judge that the gesture operation of user meets closing projected image or switches projected image
For the condition of default image.
In addition, if gesture amount of movement is pre- less than first less than or equal to dwell time after pre-determined distance threshold value, and gesture movement
If time threshold, then judge that gesture is unsatisfactory for preparatory condition, the normal operation of projection.
If gesture amount of movement is more than dwell time after pre-determined distance threshold value, and gesture movement and is more than or equal to the first preset time
Threshold value, then judge that gesture is unsatisfactory for preparatory condition, the normal operation of projection.
If gesture amount of movement is more than dwell time after pre-determined distance threshold value, and gesture movement and is less than the first preset time threshold,
Then judge that gesture is unsatisfactory for preparatory condition, the normal operation of projection.
Wherein, pre-determined distance threshold value is the threshold value of the gesture amount of movement pre-set, for example, pre-determined distance threshold value is 5cm.
Wherein, the first preset time threshold is the time threshold of dwell time after the gesture movement pre-set, for example, first
Preset time threshold is 2s.
