Structural principle and working principle of the invention are described in detail with reference to the accompanying drawing:
Refering to Figure 1, in one embodiment, step of the invention is as follows:
Scanning Trackpad (S11) simultaneously judges whether have on Trackpad touching object (S12): scanning Trackpad is to detect whether
There is touching object, if touchless object, persistently scans Trackpad.
All touching objects are set to leave unused object (S13): when scanning to when having touching object, setting all touching objects
State be idle object, therefore system will not generate corresponding instruction or hand according to detected touching object at this time
Gesture.
Wherein whether a touching object meets one first trigger condition (S14) for judgement: judging each touching object, sentences
Breaking, whether it meets preset trigger condition, and in one embodiment, which is that the shift length of touching object is
It is no to be greater than a first distance critical value, such as the first distance critical value can be 40mm to 150mm；If the touching object being judged
Meet the trigger condition, then the state of the touching object is changed to actuation object (S141) from idle object.
Judge whether that all touching objects all pass through the judgement (S15) of step S14: repeating step S14, until all
Touching object all passes through the judgement of step S14.
Judge whether that there is actuation object (S16): when all touching objects are all after the judgement of step S14, if without appointing
The state of what touching object is set to actuation object, then does not trigger any instruction (S161)；If there is any touching object
State be set to actuation object, then further calculate the quantity (S162) of actuation object.
Whether the quantity for judging actuation object is more than two (S17): if the state of only single touching object is set
It is set to actuation object, then carries out vernier control (S171)；If there are two the states of the above touching object to be set to actuation object,
Then carry out gesture judgement (S172).
Shown in please refer to figs. 2 and 3, in another embodiment, the present invention is comprised the steps of:
Scanning Trackpad (S21) simultaneously judges whether have on Trackpad touching object (S22): scanning Trackpad is to detect whether
There is touching object, if touchless object, persistently scans Trackpad.
All touching objects are set to leave unused object (S23): when scanning to when having touching object, setting all touching objects
State be idle object, therefore system will not generate corresponding instruction or hand according to detected touching object at this time
Gesture.
The quantity (S24) of judgement touching object: the quantity of detected touching object is calculated, if detecting two or more
Touching object, then follow the steps S25；If only detecting single touching object, further judge whether the touching object is full
One second trigger condition (S241) of foot then carries out vernier control (S242) when the touching object meets second trigger condition,
When the touching object is unsatisfactory for second trigger condition, then any instruction (S243) is not triggered.
Wherein whether a touching object meets a precondition (S25) for judgement: when detecting more than two touching objects
When, first determine whether each touching object meets a precondition, unsatisfied, maintaining the touching object is idle object, full
Foot then further executes step S26；
Judge whether the touching object meets first trigger condition (S26): when judging that it is preposition that the touching object meets this
When condition, further judge whether the touching object meets first trigger condition.If so, setting the touching object as actuation
Object (S261)；If it is not, then setting the touching object as preparation object (S262).In one embodiment, first trigger condition
For touch object shift length whether be greater than a first distance critical value, second trigger condition be touching object displacement away from
From whether a second distance critical value is greater than, whether the shift length of the precondition is greater than a third apart from critical value, wherein
The first distance critical value be greater than this second and third apart from critical value, and the third is greater than the second distance apart from critical value and faces
Dividing value, such as the first distance critical value can be 150mm, which can be 40mm, and the third is apart from critical value
It can be 70mm.
Judge whether that all touching objects all pass through the judgement (S27) of step S25: repeating step S25, until all
Touching object all passes through the judgement of step S25.
Judge whether with preparation object or actuation object (S28): when all touching objects all pass through the judgement of step S25
Afterwards, if the state without any touching object is set to prepared object or actuation object, any instruction (S281) is not triggered；
If there is the state of any touching object to be set to prepared object or actuation object, prepared object and actuation are further calculated
The quantity (S282) of object.
Judge whether preparation object and actuation object meet a comparison condition (S29): judging preparation object and actuation object
Quantity and state whether meet a comparison condition.If so, carrying out gesture judgement (S291)；If it is not, then carrying out vernier control
(S292)。
In one embodiment, the comparison condition of step S29, which refers to, judges whether to have more than two prepared objects.If so,
Then carry out gesture judgement (S291)；If it is not, then carrying out vernier control (S292).
In another embodiment, the comparison condition of step S29, which refers to, judges whether there is at least one actuation object and at least
One prepared object, and whether the rate travel of the preparation object is greater than a scheduled rate.If being judged as at least one work
Animal part and a prepared object, and be judged as that the rate travel of the preparation object is greater than scheduled rate, then carry out gesture judgement
(S291)；If at least one of condition is judged as NO, carry out vernier control (S292), for example, judgement do not have actuation object or
Without preparation object or judge that the rate travel of the preparation object is less than scheduled rate, then carries out vernier control.
In another embodiment, the comparison condition of step S29, which refers to, judges whether there is at least one actuation object and at least one

Row gesture control, therefore before preset triggering distance, sets a future range (i.e. third is apart from critical value), and can will not
Reach triggering distance but have reached the right hand middle finger 21 of future range, be determined as prepared object, then can right hand index finger 20 by
It is judged as actuation object, and in the case that right hand middle finger 21 is judged as prepared object, and between preparation object and actuation object
When away from less than a default spacing, directly it is judged as gesture control, and avoids first occurring unnecessary vernier control before gesture control
System.
Another practice is, when right hand index finger 20 has been judged as actuation object, and right hand middle finger 21 is judged as preparing
In the case where object, and preparation object rate travel be greater than a scheduled rate when, i.e., be directly judged as gesture control, equally may be used
Avoid first occurring unnecessary vernier control before gesture control.
Embodiment 4
It please referring to shown in Fig. 7, user is intended to cooperate left index finger 31 to carry out gesture control with right hand index finger 20, in order to avoid
There is the control of unnecessary vernier, when right hand index finger 20 and left index finger 31 reach preset future range and is judged as pre-
When standby object, due to having had more than two prepared objects, therefore triggering distance need not be reached and can directly be judged as gesture control
System, to avoid first occurring unnecessary vernier control before gesture control.
In the above embodiment, it is possible for modifying the sequence of each step, and still can achieve identical judgement knot
Fruit.The above is only the embodiment of the present invention, not limitation in any form is done to the present invention, although the present invention is
