Below in conjunction with the accompanying drawings the structural principle and operation principle of the present invention are described in detail：
Refer to shown in Fig. 1, in one embodiment, the step of the present invention is as follows：
Scanning Trackpad (S11) simultaneously judges whether there is touching object (S12) on Trackpad：Scanning Trackpad
To have detected whether touching object, if touchless object, Trackpad is persistently scanned.
All touching objects are set as the object (S13) that leaves unused：When scanning when having touching object, institute is set
The state for having touching object is idle object, therefore system will not be produced according to now detected touching object
The corresponding instruction of life or gesture.
Judge that wherein one touches whether object meets one first trigger condition (S14)：Each touching object is entered
Row judges that judge whether which meets default trigger condition, in one embodiment, first trigger condition is
Whether more than one first apart from marginal value, for example this first apart from marginal value can be the shift length of touching object
40mm to 150mm；If estimative touching object meets the trigger condition, by the shape of the touching object
State is changed to start object (S141) from idle object.
Judge whether all touching objects all through the judgement (S15) of step S14：Repeat step S14,
Until all touching objects are all through the judgement of step S14.
Judge whether with start object (S16)：When all touching objects are all through the judgement of step S14
Afterwards, if the state without any one touching object is set to start object, any instruction (S161) is not triggered；
If the state for having any touching object is set to start object, the quantity of start object is further calculated
(S162).
Whether the quantity for judging start object is two or more (S17)：If only single touching object
State is set to start object, then carry out vernier control (S171)；If there is two or more touching object
State is set to start object, then carry out gesture judgement (S172).
Refer to shown in Fig. 2 and Fig. 3, in another embodiment, the present invention is comprised the steps of：
Scanning Trackpad (S21) simultaneously judges whether there is touching object (S22) on Trackpad：Scanning Trackpad
To have detected whether touching object, if touchless object, Trackpad is persistently scanned.
All touching objects are set as the object (S23) that leaves unused：When scanning when having touching object, institute is set
The state for having touching object is idle object, therefore system will not be produced according to now detected touching object
The corresponding instruction of life or gesture.
Judge the quantity (S24) of touching object：The quantity of detected touching object is calculated, if detection
Plural touching object is arrived, then execution step S25；If only detecting single touching object, enter one
Step judges whether the touching object meets one second trigger condition (S241), when the touching object meet this
During two trigger conditions, then vernier control (S242) is carried out, when the touching object is unsatisfactory for the second triggering bar
During part, then any instruction (S243) is not triggered.
Judge that wherein one touches whether object meets a precondition (S25)：Plural when detecting
During touching object, first determine whether whether each touching object meets a precondition, unsatisfied, maintain this to touch
Object is touched for idle object, then further execution step S26 of satisfaction；
Judge whether the touching object meets first trigger condition (S26)：When judging that the touching object is full
During the foot precondition, determine whether whether the touching object meets first trigger condition.If so, then
The touching object is set as start object (S261)；If it is not, then setting the touching object as preparing object
(S262).In one embodiment, first trigger condition is whether the shift length for touching object is more than one
First apart from marginal value, and second trigger condition is whether the shift length for touching object is more than a second distance
Whether marginal value, the shift length of the precondition are more than one the 3rd apart from marginal value, wherein first distance
Marginal value more than this second and third apart from marginal value, and the 3rd faces more than the second distance apart from marginal value
Dividing value, for example this first apart from marginal value can be 150mm, the second distance marginal value can be 40mm, should
3rd can be 70mm apart from marginal value.
Judge whether all touching objects all through the judgement (S27) of step S25：Repeat step S25,
Until all touching objects are all through the judgement of step S25.
Judge whether with preparation object or start object (S28)：When all touching objects are all through step
After the judgement of S25, if the state without any one touching object is set to prepare object or start object,
Any instruction (S281) is not triggered；If the state for having any touching object is set to prepare object or work
Animal part, then further calculate the quantity (S282) of preparation object and start object.
Judge whether prepare object and start object meets a comparison condition (S29)：Judge preparation object and
Whether the quantity and state of start object meets a comparison condition.If so, gesture judgement (S291) is then carried out；
If it is not, then carrying out vernier control (S292).
In one embodiment, the comparison condition of step S29 refers to and judges whether with plural back log
Part.If so, gesture judgement (S291) is then carried out；If it is not, then carrying out vernier control (S292).
In another embodiment, the comparison condition of step S29 refers to and judges whether with least one start object
And at least one preparation object, and whether the rate travel of the preparation object is more than a scheduled rate.If judging
Be object to be prepared with least one start object and one, and be judged as that the rate travel of the preparation object is big
In scheduled rate, then carry out gesture judgement (S291)；If at least one of conditional judgment is no, carry out
Vernier control (S292), for example, judge not there is start object or not there is preparation object or judge to be somebody's turn to do
The rate travel of preparation object then carries out vernier control less than scheduled rate.
In another embodiment, the comparison condition of step S29 refer to judge whether with least one start object and
At least one preparation object, and the start object is pre- less than one with the range difference of the displacement of the preparation object
If range difference.If being all judged as YES, gesture judgement (S291) is carried out；If at least one of conditional judgment
It is no, then carries out vernier control (S292).
In another embodiment, step S29 of the present invention can determine whether any one comparison condition aforesaid or can sentence
Any two comparison conditions aforesaid of breaking can determine whether aforesaid three kinds of comparison conditions.When judge two or more before

The control method of the contactor control device of the present invention is illustrated with several specific embodiments below, only
It is not used to limit the present invention for illustrating：
Embodiment 1
Refer to shown in Fig. 4, the right hand forefinger 20 of user in 10 vernier control to be carried out of contactor control device,
As all touching objects are first predetermined to be idle object, therefore when the movement of right hand forefinger 20 is more than default
Triggering apart from when, then carry out corresponding vernier control, due to now only having single touching object, therefore will not
Have and the situation of erroneous judgement is produced because of idle object, then the threshold value of triggering displacement is relatively low, in order to quick
The vernier control kept straight on by reaction user, without there is the impression for allowing user to feel vernier response lag.
Embodiment 2
Refer to shown in Fig. 5, on contactor control device 10, pre-existed the idle left-hand palm 30 of user, this
When user right hand forefinger 20 in 10 vernier control to be carried out of contactor control device, due to all touching objects equal
Idle object is first predetermined to be, therefore the only mobile right hand forefinger 20 for exceeding default triggering distance is judged
Corresponding vernier control is carried out for start object, and the left-hand palm 30 is not then because reaching default triggering
Distance, and maintain idle object, thus, then will not be because there are idle left-hand palm 30 and shadow
Ring to the vernier control for judging right finger 20.
Embodiment 3
Refer to shown in Fig. 6, on contactor control device 10, pre-existed the idle left-hand palm 30 of user, this
When user right hand forefinger 20 and right hand middle finger 21 in 10 gesture control to be carried out of contactor control device, due to
All touching objects are first predetermined to be idle object, therefore only action exceedes the right hand of default triggering distance
Forefinger 20 and right hand middle finger 21 are judged as start object and carry out corresponding gesture and judge, and the left hand
Palm 30 then because not reaching default triggering distance, and maintains idle object, thus, then will not be because of depositing
Gesture judgement is had influence on there is an idle left-hand palm 30.
Furthermore, it is assumed that right hand forefinger 20 is relatively early to touch contactor control device 10, right hand middle finger 21
Later touch contactor control device 10, then because of small time difference, and right hand forefinger 20 will likely be caused first
Break through default triggering distance and be then mistaken for only one of which start object, but actually user is used to the right side
Handss middle finger 21 coordinates 20 upward sliding of right hand forefinger to carry out gesture control, therefore before default triggering distance,
A future range (the i.e. the 3rd apart from marginal value) is set, and can have been reached not up to triggering distance but preposition
The right hand middle finger 21 of distance, is judged to prepare object, then can be judged as making animal in right hand forefinger 20
Part, and in the case that right hand middle finger 21 is judged as preparing object, and prepare between object and start object
Away from during less than a preset pitch, directly it is judged as gesture control, and avoid first occurring before gesture control need not
The vernier control that wants.
Another kind of practice is that when right hand forefinger 20 has been judged as start object, and right hand middle finger 21 is judged to
In the case of breaking as preparing object, and when preparing the rate travel of object more than a scheduled rate, i.e., directly sentence
Break as gesture control, can equally avoid first occurring unnecessary vernier control before gesture control.
Embodiment 4
Refer to shown in Fig. 7, user is intended to coordinate left index finger 31 to carry out gesture control with right hand forefinger 20,
In order to avoid there is unnecessary vernier control, when right hand forefinger 20 and left index finger 31 reach default
Future range and when being judged as preparing object, due to having plural preparation object, therefore need not reach
Gesture control can be directly judged as to triggering distance, to avoid first occurring unnecessary trip before gesture control
Mark control.
In above embodiment, the order of changing each step is possible, and can still reach identical
Judged result.The above is only embodiments of the invention, not the present invention is done any pro forma
Limit, although the present invention is disclosed above with embodiment, but is not limited to the present invention, any ability
