The towing gesture judgment method comprises the steps of: comparing signal values of one or a plurality of detection signals produced by the touch sensing device with one or a plurality of critical values, judging whether a touch event happens or not according to a comparison result, and determining the happening of a towing gesture if the touch event happens.
Description
Technical field
The present invention relates to towing (moving point) gesture determination methods; Relate in particular to a kind of towing gesture determination methods, touch-control sensing control chip, use this touch-control sensing control chip touch-control system and computer system; Therefore the user need not confirm that action can directly pull the pairing object of its touch point, can intuitively and expediently operate.
Background technology
In general, the touch control induction device of touch control induction device such as other type such as condenser type, resistance-type can produce the detection signal that is relevant to this touch-control incident in a touch-control sensing chip when the user carries out a touch-control incident.The touch-control sensing chip is made comparisons the signal value and the critical value of detection signal again, and according to comparative result decision touch point, and then judge gesture.With the capacitance touching control induction installation is example; The capacitive touch control techniques mainly is the inductance capacitance variation that is produced when touch point on the contact panel contacts by the detecting human body; Judge the touch-control incident, in other words, promptly utilize the capacitance characteristic difference of a certain touch point of human body touch front and back; With the judgement touch point, and judge that according to this touch-control incident realizes touch controllable function.
Particularly, please refer to Fig. 1, Fig. 1 is the synoptic diagram of a known projected capacitive induction installation 10.Electric capacity projected capacitive induction installation 10 includes inductance capacitance serial X

nRespectively in order to differentiate the touch-control incident of horizontal direction and vertical direction.With the example that is operating as of horizontal direction, suppose inductance capacitance serial X
1A inductance capacitance arranged, and the capacitance of each inductance capacitance is C, then under the normal condition, and inductance capacitance serial X
1Capacitance be aC, and touch inductance capacitance serial X when human body (for example finger)

nPredetermined capacitance can be identical also can be different, must look actual demand and decide.
From the above; The touch-control sensing chip can compare the signal value and the preset critical of the detection signal that touch control induction device produced; Therefore can take place to the process that finishes, to determine that the position of all touch points and touch-control continue time of origin in a touch-control incident, and then judge gesture.
In judgement about the towing gesture; Because known towing gesture is useful in the Trackpad of mobile computer, and the Trackpad area is limited, and the screen area of mobile computer is the several times of touch control induction device area; Therefore can only use relative position mapping and then operation; So the identification of known towing gesture needs a Rule of judgment, it requires the user to need to click earlier to confirm to treat trailer, and the side is to avoid judging by accident the position of treating trailer.
Particularly, please refer to Fig. 2, Fig. 2 is the synoptic diagram of the Rule of judgment of a known towing gesture.In Fig. 2, on behalf of this time point, arrow begin touch-control downwards, promptly corresponding one get into touch point (enteringpoint), and on behalf of this time point, arrow upwards finish touch-control, promptly corresponding one leaves touch point (leavingpoint).As shown in Figure 2, beginning for the first time touch-control is one to continue time of origin T1 to the time of leaving, and the second time touch-control begin to the first time touch-control to begin institute be a touch-control T2 interval time interval time.Under this situation, the Rule of judgment of known towing gesture is little of a reference time T1 at lasting time of origin T1
RefAnd touch-control T2 interval time is little of a reference time T2
RefWhen setting up simultaneously, just determine a towing gesture to take place.This Rule of judgment is meaning, and the user must click for the first time earlier and confirm to treat trailer, then at reference time T2 when the operation drag kick
RefIn carry out again for the second time and click, could really begin to pull this and treat trailer.
Please again with reference to figure 3, Fig. 3 is the operation chart of known towing gesture.In Fig. 3, be to illustrate with mobile computer.One screen 32 provides the user required information, and a Trackpad 30 then is available for users to contact to carry out touch control operation.Because Trackpad 30 areas are little than screen 32 areas, or Trackpad 30 is not to overlap to be provided with screen 32, so Trackpad 30 has the relation of relative position mapping with screen 32.As shown in Figure 3, screen 32 display object OB1, OB2 and a cursor CS.In the case; When user's desire towing object OB1; Because Trackpad 30 has the relation of relative position mapping with screen 32, so the user needs behind the flow process several of clicking, move, leaving on the Trackpad 30, could cursor CS be moved to object OB1 top by the origin-location.Then the user clicks confirming object OB1 again, and again at reference time T2
RefIn click again and begin towing.It should be noted that in cursor CS moving process, possibly take place that cursor CS is parked in object OB2 top and flow process that the user just clicks, moves, leaves, but since known towing gesture click earlier and confirm, then at reference time T2
RefIn click again and just begin towing, so can't judge by accident to object OB2 is pulled.
Yet touch control induction device (for example be the touch surface version) waits that to integrate mutually with screen and have other type touch control induction devices of absolute position mapping relations each other luxuriant be main flow in recent years.What so-called absolute position mapping relations were represented is; The absolute position of any touch point can directly be mapped as the absolute position of any touch point on the screen on the touch control induction device, that is the resolution of touch surface version and screen can a bit be shone upon the mode of a bit.In this type device, the area of touch control induction device and screen much at one, or touch control induction device and the screen setting that overlaps mutually.When using this type device, the user can move on screen carrying out touch-control intuitively, and the absolute position on the screen of institute's touch-control is a corresponding absolute position on the contact panel.Yet as described above said, the complicated Rule of judgment of known towing gesture does not but allow the user on this type device, intuitively to carry out drag operation easily.
In view of this; Under the technical development that the position relation in response to touch surface version and screen changes; The real necessity that improvement is arranged of the Rule of judgment of known towing gesture; With the touch control induction device that more can be useful in and screen shines upon according to the absolute position, and allow the user more intuitively to pull the operation of gesture easily.

Please refer to Fig. 4, Fig. 4 is the square Organization Chart according to the computer system 40 of an embodiment.As shown in Figure 4, computer system 40 mainly is made up of a touch control induction device 400, a touch-control sensing control chip 402 and 404 in a main frame, and wherein, touch control induction device 400 and touch-control sensing control chip 402 constitute a touch-control system.
It (for example is finger, pen that touch control induction device 400 can be responded to object under test ... Deng) and produce one or more touching signals of representing the position of this object under test on a detecting panel (not shown).Touch-control sensing control chip 402 includes a detecting unit 406 and a judging unit 408.Detecting unit 406 is used for the signal value of this one or more detection signal and one or more critical value are made comparisons, and judging unit 408 judges whether to take place any touch-control incident according to a result of this comparison then.In case judging unit 408 judges when having a touch-control incident TE to take place that it also determines a towing gesture to take place.In addition, judging unit 408 still continues to compare after touch-control incident TE takes place, and judges according to result relatively whether touch-control incident TE finishes.If touch-control incident TE finishes, just decision towing gesture finishes.In addition, judging unit 408 can be sent to main frame 404 with a package Pac of representative towing gesture.
Below be the explanation that example is done thin portion with capacitive touch-control system; Wherein touch control induction device 400 is preferably a capacitance type touch-control panel that combines with a screen 410 of computer system 40; But also can analogize the touch-control system of other types such as resistance-type; As long as wherein touch control induction device 400 shines upon according to the absolute position with the screen 410 of computer system 40, and does not limit example explanation herein.Capacitive touch control induction device 400 can produce corresponding to inductance capacitance serial X

mIn do not have any capacitance signal greater than vertical critical value Cvt or capacitance signal CY
1～CY
nIn when not having any capacitance signal greater than horizontal critical value Cht, judging unit 408 can judge that touch-control incident TE finishes, and also decision towing gesture finishes.Simultaneously, judging unit 408 also can determine to pull gesture the terminal point position in a towing path when touch-control incident TE finishes one leave touch point TO1 the position.
In said process, judging unit 408 can produce a corresponding package Pac and give main frame 404, and main frame 404 is operated according to package Pac.Must note, vertical critical value Cvt and horizontal critical value Cht can be identical also can be different, must look actual demand and decide.The relevant running part of above-mentioned judgement touch point can be similar with projected capacitive induction installation 10, repeats no more at this.As a result, the object that the user can pull institute's desire is intuitively clicked directly towing of back, does not just begin towing and do not need to click after click is confirmed earlier again.
It should be noted that; For guaranteeing that touch-control incident TE takes place but not false touch really; Under preferable situation; Detecting unit 406 sustainable will comparing with vertical critical value Cvt, horizontal critical value Cht respectively corresponding to one or more capacitance signal (as corresponding to the capacitance signal that gets into touch point TI1) of same position continue time of origin T3 to detect one.Judging unit 408 then can decide touch-control incident TE whether to occur in this same position according to lasting time of origin T3.For example, judging unit 408 can judge touch-control incident TE lasting time of origin T3 whether greater than a special time T3
RefIf judged result is for being, judging unit 408 just determines touch-control incident TE to occur in this same position (pulling the entering touch point TI1 of start bit set when touch-control incident TE takes place of gesture like decision).Otherwise if judged result is not, 408 decisions of judging unit touch-control incident TE does not occur in this same position.
When the towing beginning, implement in the specific embodiment of above-mentioned affirmation mechanism; Touch-control sensing control chip 402 must scan touch control induction device 400 one by one; And each area capacitance value is processed into corresponding touch point coordinate position, that is to scan and judge touch point (each time cost is about 10ms for example) one by one.When each scanning; Detecting unit 406 can be done comparison with vertical critical value Cvt, horizontal critical value Cht respectively at this one or more capacitance signal that will correspond to this same position; And when the result of this comparison indicated a contact condition (make), detecting unit 406 just write to a sequence QE with a bit combination 01.And judging unit 408 is when detecting number of times that sequence QE write bit combination 01 continuously greater than a specific times CM, and the lasting time of origin T3 that just can judge touch-control incident TE is greater than special time T3
Ref, and then the entering touch point TI1 of the position of decision towing gesture when occurring in touch-control incident TE and taking place.Be one 8 bit sequences for example as if sequence QE, when sequence QE is 01010101, the entering touch point TI1 the when position of judging unit 408 decision towing gestures occurs in touch-control incident TE generation.
Similarly; For guaranteeing that touch-control incident TE finishes but not spring (bounce) really; In a preferred embodiment; Detecting unit 406 sustainable will comparing with vertical critical value Cvt, horizontal critical value Cht respectively corresponding to one or more capacitance signal (as corresponding to the capacitance signal that gets into touch point TO1) of same position continue stand-by time T4 to detect one.Judging unit 408 then can decide touch-control incident TE whether to occur in this same position according to lasting stand-by time T4.For example, judging unit 408 can judge touch-control incident TE lasting stand-by time T4 whether greater than a special time T4
RefIf judged result is for being, judging unit 408 finishes this same position (leaving when occurring in touch-control incident TE end like the position of decision towing gesture touch point TO1) with regard to determining touch-control incident TE.Otherwise if judged result is not, 408 decisions of judging unit touch-control incident TE does not finish at this same position.
, towing implements in the specific embodiment of above-mentioned affirmation mechanism when finishing; Touch-control sensing control chip 402 must scan touch control induction device 400 one by one; And each area capacitance value is processed into corresponding touch point coordinate position, that is to scan and judge touch point (each time cost is about 10ms for example) one by one.When each scanning; Detecting unit 406 can be done comparison with vertical critical value Cvt, horizontal critical value Cht respectively at this one or more capacitance signal that will correspond to this same position; And indicate one not during contact condition (break state) as the result of this comparison, detecting unit 406 just writes to sequence QE with a bit combination 00.And judging unit 408 is when detecting number of times that sequence QE write bit combination 00 continuously greater than a specific times CB, and the lasting time of origin T4 that judges touch-control incident TE is greater than special time T4
Ref, and the entering touch point TO1 of the position of decision towing gesture when occurring in touch-control incident TE and taking place at the beginning.For example if sequence QE is one 8 bit sequences, when sequence QE is 00000000, when being that touch-control incident TE finishes, the position, final position of judging unit 408 decision towing gestures leaves touch point TO1.
Below will the embodiment that main frame 404 operates according to package Pac be described with Fig. 5 A to Fig. 5 B.Please refer to Fig. 5 A and Fig. 5 B, Fig. 5 A and Fig. 5 B are that the towing gesture of touch control induction device 400 among embodiment of the invention Fig. 4 is at the synoptic diagram of host service function under different mode.Shown in Fig. 5 A; In one embodiment; Main frame 404 operates in a desktop at the beginning; Therefore when user's desire is pulled an object OB3, the user can be intuitively directly begins touch-control at the entering touch point TI1 that screen showed and moves to then and leave touch point TO1 and finish touch-control, and the starting point position in towing path that this moment, judging unit 408 can determine to pull gesture is in the position of entering touch point TI1; And the terminal point position in decision towing path is in the position of leaving touch point TO1, and all touch points of decision towing process.In addition, judging unit 408 can transmit corresponding package Pac and give main frame 404, makes main frame 404 will get into the pairing object OB3 of touch point TI1 and is towed to by the origin-location and leave the pairing position of touch point TO1.
On the other hand; Shown in Fig. 5 B; In another embodiment; Therefore suppose that main frame 404 operates under the pencil pattern of little artist's program at the beginning, when the user desires to carry out setting-out, the user can be intuitively directly begins touch-control and moves to then and leave touch point TO1 end touch-control getting into touch point TI1; The starting point position in towing path that this moment, judging unit 408 can determine to pull gesture in the position that gets into touch point TI1, the terminal point position in decision towing path is in the position of leaving touch point TO1, and all touch points of decision towing process.In addition; Carrying out in the process of towing; Judging unit 408 can transmit corresponding package Pac again and give main frame 404; Make main frame 404 begin setting-out by getting into the pairing position of touch point TI1, and to all touch points pairing position setting-out of towing process till leaving the pairing position of touch point TO1.
Must note; The starting point position in towing path that touch-control sensing control chip 402 can determine to pull gesture in the above-mentioned instance in the position that gets into touch point TI1, the terminal point position in towing path is in the position of leaving touch point TO1; And all touch points of towing process; And utilize package Pac indication main frame 404 again, so that main frame 404 carries out the difference running according to its different operation modes.Right the present invention does not limit at this.For instance; As user simultaneously on the touch-control touch control induction device 400 2 time; Touch-control sensing control chip 402 can determine the position of two towing gestures to occur in respectively and get into touch point, finish at all touch points that leave touch point and towing process the position; And the package Pac that is seen off is except that comprising above-mentioned information; Also indicate two towing gestures to take place simultaneously, so that main frame 404 according to which kind of gesture operation of change in location decision of this towing gesture, for example amplifies (zoom in), dwindles (zoom out) or rotation gesture operations such as (rotate).
Must notice that the purposes that the judgment mode of the towing gesture of the foregoing description and associated description are only explained as example limits mode all not limit at ad hoc rules in fact.As long as under the situation of screen according to the absolute position mapping of touch control induction device 400 and computer system 40; The user does not need to click earlier to confirm; The position that touch-control sensing control chip 402 can directly determine to pull gesture occurs in the entering touch point of touch-control incident, makes the user to pull gesture intuitively and gets final product.Those of ordinary skills are not judgment mode and the mode of operation shown in Fig. 4, Fig. 5 A and Fig. 5 B when modifying according to this or change and do not limit.
