Background technology
With the development of electronic information technology, the terminal based on technologies such as body-sensing input technology, Gesture Recognitions obtains
It is widely applied.This Terminal Type has in common that user can pass through limb action, gesture motion etc. using this Terminal Type
Contactless input mode realizes information input or terminal is operated.And in various operational motions, user is most normal
Use the process of the analog mouse operational motion such as click, dragging, page turning.
In current technology, for the operational motion of analog mouse, gesture and mouse would generally be preset in the terminal
Mapping relations, when user makes one or more gestures, the gesture that terminal can be made according to user determines whether to be clicked on
Operation.Such as：The movement of the corresponding analog mouse pointer of palm movement can be preset in somatosensory recognition terminal, corresponding simulation mouse of clenching fist
Target clicking operation, it is changed into the operation that palm is then the release click of analog mouse from clenching fist.If user is needed to projection
Content carries out page turning, then needs to move the pointer to the page edge being projected out using palm, clicks on pointer by clenching fist, goes forward side by side
Row page turning, after one page is twisted over, then it will clench fist and be changed into palm, be clicked on so as to discharge.
However, in the practical application of prior art, generally require continually to be clicked on, drag, the operation such as page turning, this
User is just needed rapidly to carry out gesture conversion, such as：User is to continuous page turning, it is necessary to rapidly carries out palm → clench fist
The gesture switching of → palm.If user often carries out the fatigue that prolonged operation easily causes hand, four limbs.

Mark, the drag events are to move the cursor according to the movement locus of the target object, and the release event is to described
The click of the current position of cursor.
204, mobile cursor, and continue executing with step 201.
Wherein, if the acceleration of target object is less than the pre-determined threshold, terminal continues continuous tracking target object
The situation of change of space coordinates, and cursor is moved on screen according to the situation of change of the space coordinates of target object.
205, continue detect target object acceleration, judge target object acceleration be consistently less than specified threshold when
Between whether it is big at fixed time；If the time that the acceleration of target object is consistently less than the specified threshold is more than described specified
Between, then perform step 207；If the time that the acceleration of target object is consistently less than the specified threshold is not more than described specified
Between, then perform step 206.
206, drag events are performed, and continue executing with step 205.
Drag events are used for the drag operation of analog mouse.Such as：Terminal is more than or equal in the acceleration of target object
Pre-determined threshold, can be using DOWN event+MOVE events as drag events after performing DOWN events.
207, perform release event.
