Description
Technical field
The present invention relates to the gesture judging method of a kind of contactor control device, be specifically related to a kind of touch-control dress
Put edge and sweep sliding gesture judging method.
Background technology
Trackpad or the circumscribed Trackpad of notebook computer replace mouse merit for the convenience of the users
Can, substantially there is cursor control function, left button function and right button function, and along with computer system
The software development of system business, this type of Trackpad starts to increase " edge is swept skating gesture and controlled function ".
For example, after computer system opens window function row hidden function, user utilizes touch-control
When plate carries out cursor control function, left button function and right button function, this window function row are hidden
Tibetan state, once this Trackpad judges that currently used person controls gesture as " skating gesture is swept at edge
(Edge Swipe) " time, hidden function row function is shown in window and draws by this computer system the most automatically
On face, click for user；In addition as the most applicable in page layout switch function.
Computer system business Microsoft i.e. formulates " skating gesture is swept at edge " judgment principle at present, but
Actual cooperation Trackpad still has judgement rate too low after using, and uses inconvenience sense to occur, as described below.
First please refer to shown in Fig. 9, the Trackpad 10 of a notebook computer according to use habit in
Front side is left and right half side is designed as left button function and right button function, user by left and right half side i.e.
Computer system can be controlled and perform left button function and right button function；As for " edge is swept skating gesture and controlled
Function " then specification is in the nearly left side of Trackpad, nearly right side and the marginal area of nearly rear side.Join again
Shown in conjunction Figure 10, tool edge is swept the Trackpad 10 of skating gesture arbitration functions and is preset with " marginal area
Width W ", " object displacement R ", " object move angle upper limit αT" and " object moves
Dynamic angle lower limit αB", and determination methods includes following steps:
Several positional informationes are read according to one scan time cycle ground within certain time (Tswipe),
Wherein the first stroke positional information falls in this marginal area；
With the first stroke positional information and other positional information calculation go out single object moving direction and
Displacement；
When the moving direction judging object falls in default move angle upper limit αTAnd lower limit αBBetween
In angular range, and displacement exceedes object displacement R person, then be judged as that skating is swept at edge
Gesture.
When finger slips into Trackpad one edge from shell, this Trackpad 10 the first stroke positional information
Necessarily fall into this marginal area, and carry out edge and sweep the judgement step of skating gesture；I.e. move when object
Dynamic direction meets the move angle preset, as long as object displacement exceedes within a certain period of time
This displacement, is i.e. judged as that skating gesture is swept at edge.
Though but above-mentioned determination methods can determine whether that skating gesture is swept at the edge of user, but causing and make
By uncertainty, as shown in Figure 11 A and Figure 12 A, above-mentioned determination methods is judged as that skating is swept at edge
The schematic diagram of gesture,
Owing to different Trackpads all can set different time scan period, as shown in Figure 11 A, when
It is t0 that user actual finger touches this Trackpad 10 position P1 time, but because of time scan period
It is related to that this Trackpad 10 just reads in the first sum of positional information of existing object in the t1 time, touching of its correspondence
Control Board position is P1 ', adds that establishment edge is swept skating must certainly will judge that this object is from P1 ' position always
Mobile more than one " displacement " R, therefore for Trackpad, it is judged that user finger is necessary
After one tunnel slips over the P2 position of this Trackpad, just can trigger edge and sweep sliding function (P2-P1 ' >=R)；
Therefore, even if user can ensure that sweeping skating refers to touch the drop point first of Trackpad all same every time
One position, such as Figure 12 A, but as scan period time relationship, this Trackpad is in the t3 time
Just read in the first sum of positional information correspondence Trackpad position P1 ", it is the most farther with P1, such as figure
Shown in 12B, cause sometimes to sweep sliding relatively long distance (more than P3) just trigger sweep sliding function ((P3-P1 "
≥R).Therefore, using the Trackpad of above-mentioned determination methods, when actually used, user can
As long as a sliding short distance can be swept just can be triggered and sweep sliding function, but sometimes to sweep sliding longer distance
Can be triggered this and sweep sliding function, cause use uncertainty；Furthermore, user drop point first
All probability in Trackpad same position are lower, cause above-mentioned use uncertainty phenomenon more aobvious
Write, it is thus regarded that this Trackpad is abnormal.
Furthermore, can judge two finger adopting consecutive click chemical reactions by accident due to above-mentioned determination methods is that skating gesture is swept at edge,
More often appear as user use keyboard time, easily made because of accident touch on touch control 10 plate marginal area W
Become.Such as Figure 13 A, if finger or palm first touch marginal area W, meet the most again this and preset
In time, (t2-t0 < Tswipe) touches Trackpad 10 again, as shown in Figure 13 B, and this time touches
Positional information and the displacement difference first touched between the positional information of this marginal area W the most
Exceeding this displacement R person, as shown in Figure 14 A, 14B, then can judge by accident becomes edge and sweeps skating
Gesture.In addition to the technical problem that above-mentioned determination methods cannot correctly judge " skating gesture is swept at edge ",
Owing to judging that the most angled scope of condition and the displacement of skating gesture are swept in edge, if therefore mobile
It is improper that distance sets, and the most easily the erroneous judgement tap gesture that slightly tilts of user judges into that " edge is swept by accident
Skating gesture ", therefore at present edge is swept the Rule of judgment that sliding gesture judging method used and be there is no method
It is effectively improved edge and sweeps the judgment accuracy of skating gesture.
Therefore, have at present edge sweep skating gesture control function Trackpad judge " edge is swept
Skating gesture " False Rate the highest, therefore be necessary to improve further.

Furthermore, for avoiding reciprocating gesture be mistaken for being controlled light target at first area A
Skating gesture is swept at edge, by each positional information rear decision objects compared with its next record positional information
Direction of displacement, persistently judges whether each direction of displacement is satisfied by by a lateral margin of this contactor control device 10
To the moving direction away from this lateral margin, until completing edge to sweep the judgement of skating gesture.
Please also refer to shown in Fig. 2, for the detail flowchart of the present invention the first preferred embodiment,
First the first stroke positional information (S10) is read, when the first stroke positional information falls into first area
A (S11), then proceed edge and sweep the judgement of skating gesture；Otherwise, then general cursor control it is considered as
Gesture processed and direct output position information (S111).When the first stroke positional information falls into first area
A (S10), reads in next record positional information (S12) then at the lower scan cycle time, it is judged that this pen
Whether positional information falls into second area B (S13), if it is not, then then at the lower scan cycle time
Read next record positional information (S12), equally judge whether to fall into second area (S13)；So repeat
Until Preset Time has a positional information to fall into second area B before arriving, just it is judged as that edge is swept
Skating gesture (S132)；If not having a position information to fall into second area at Preset Time to reaching
B (S131), then export (S133) by positional information.It is owing to each positional information reads the time
The sweep time of contactor control device 10, the most different contactor control devices 10 can according to its scan period time
Between, directly preset and read in the stroke count judging edge touch control gesture；In short, judging still in advance
If during time step S131, can the most be reached replacement by default stroke count.
Continuing with coordinating refering to shown in 5B, sweep sliding gesture judging method second for edge of the present invention
The flow chart of preferred embodiment, includes following steps:
The sensing substrate of contactor control device defines a first area A, a second area B and
3rd region C；Wherein this first area A adjoins a lateral margin of this contactor control device 10, and this second
Region B is adjacent between this first area A and the 3rd region C；
Several positional informationes of object on contactor control device 10 are read in a Preset Time；Wherein should
Preset Time is for sweeping the sliding time, and the actual Preset Time realizing the present invention, can be according to touch-control
Device is preset the scanning periphery time and is relatively swept the sliding time, with the stroke count of reading positional information come certainly
Determine Preset Time, can non-actual set one Preset Time；
Judge whether the first stroke positional information of several positional informationes falls in the A of this first area；
Judge whether other arbitrary positional information falls into this second area B the most again；And
If so, the strokes positional information after this positional information that will fall into second area B, sentences
Whether disconnected have arbitrary pen to fall into the 3rd region C；If the person of meeting, judge that action is that skating is swept at edge
Gesture.
Similarly, for avoiding reciprocating gesture erroneous judgement by being controlled light target at first area A
Sweep skating gesture for edge, order for judge each the positional information falling into the 3rd region C and its next
Positional information compares rear decision objects direction of displacement, and judges whether each direction of displacement is satisfied by
By a lateral margin of this contactor control device 10 to the moving direction away from this lateral margin, sweep until completing edge
Till the judgement of skating gesture.
Please coordinate shown in Fig. 4, Fig. 5 A and Fig. 5 B, for the invention described above the second preferred embodiment
Flow chart, it is identical with Fig. 4 major part process step, but once has arbitrary positional information full
After foot falls into second area, further read next record positional information, and judge whether to fall into
3rd region, if it is not, then read next record positional information (S12) then between lower scan cycle, one
Sample judges whether to fall into the 3rd region (S13)；So repeat until Preset Time has one before arriving
Positional information falls into the 3rd region, is just judged as that skating gesture (S132) is swept at edge；If not presetting
Time has a position information to fall into second area B (S131) before arriving, then exported by positional information
(S133).It is the sweep time of contactor control device, the most not owing to each positional information reads the time
Same contactor control device can directly be preset reading judge edge touch-control hands according to its time scan period
The stroke count of gesture；In short, when judging still at Preset Time step (S131), can be by default stroke count
The most reach substituted.
Above-mentioned edge sweep sliding gesture judging method must judge finger sequentially occur in first area,
Second area and the 3rd region, just can be judged as that skating gesture is swept at edge, can get rid of whereby and sequentially touch
Touch the secondary point hand-touch gesture of first area and second area to be mistaken for edge and sweep the defect of skating gesture
(getting rid of the situation of 13A and 14A figure).
Furthermore, for avoiding sweeping of some user to slip over soon, and make this contactor control device 10 read
The first stroke positional information does not falls within first area, please refer to Fig. 6, is preferably to implement with first
Add second edge as a example by example and sweep skating gesture determining program (S111 ').Refer to again shown in Fig. 7,
Judging that the first stroke positional information does not falls within the second edge that first area (S11) performs afterwards and sweeps cunning
Gesture determining program includes:
Judge whether the first stroke positional information falls at this second area (S20, S21), if it is not, the most defeated
Out position information (S211)；
Whether judge the most again between this first stroke positional information and other arbitrary positional information
There is displacement difference (S22, S23)；And
If having, and when this displacement difference is more than a preset value, then judgement action is that skating gesture is swept at edge
(S24)；And
If nothing, the most still in Preset Time (S25), repeat step (S22, S23), until sentencing
Disconnected skating gesture of sweeping, or till Preset Time arrival；If the most not in Preset Time, then export
Confidence breath (S211).
As shown in the above description, when contactor control device application touch control plate of the present invention, due to Trackpad relatively
General Touch Screen is little, therefore the user of sliding function is swept at the edge of part contact panel accustomed to using,
Often can sweep sliding function with the edge of big-movement operation Trackpad, therefore finger touch position first is led to
It is often notebook computer casing, and the digit speed actually entering Trackpad is not 0, therefore, this
Invention also can as shown in Figure 8, and the first stroke positional information read when this contactor control device 10 does not falls within the
One region A, as long as judging that the first stroke positional information Xa+1 and other positional information Xa has displacement
Difference d11, and acquisition exceedes default with the displacement difference of wherein positional information in Preset Time
Value, can be judged as that skating gesture is swept at edge；Wherein, this preset value is based on typically sweeping skating gesture
Sweep slip velocity degree and this Trackpad is preset sweep time and is set, therefore judging displacement difference more than this
During preset value, i.e. represent and fall into the finger initial velocity of this marginal area and be not zero, and meet
The digit speed of skating gesture is swept at edge, it is possible to be judged as that skating gesture is swept at edge.
In sum, the present invention has mainly defined one outside the either side cause of contactor control device inside
First area and a second area, as long as therefore judging that the first stroke positional information falls into first area,
And sweep in the sliding time (Preset Time) at one, arbitrary pen of its remainder positional information also falls into
Two regions, then represent and have a pair on contactor control device as if slided toward away from this side from one lateral margin,
And it is judged as that skating gesture is swept at edge；It is additionally, since the first distance and second distance is fixing, should
First area and second area on contactor control device are fixed range, therefore user sweep cunning
Finger must first fall in first area, and just can trigger this by the second area on contactor control device
Sweep sliding function, therefore user can be accustomed to wanting finger to slip over first area just triggering and sweep sliding function,
The uncertainty of skating gesture is swept at the edge solving existing Trackpad；Furthermore, owing to the present invention only needs
Set first area width and second area width, it is not necessary to set " object displacement ", " right
As the move angle upper limit " and " object move angle lower limit ", reduce because different users sweeps cunning
It is accustomed to different judgement False Rates, and reduces Rule of judgment and also can promote reaction sensitivity.
Although, the present invention is as embodiment to carry out edge in the above-described embodiments using Trackpad
Sweep the judgement of skating gesture, with function corresponding in trigger action system, but be not limited thereto,
