Below will coordinate graphic and embodiment describes feature of the present invention and embodiment in detail, content is enough to make any related art techniques person of haveing the knack of can fully understand easily the applied technological means of technical solution problem of the present invention and implement according to this, realizes whereby the attainable effect of the present invention.
The present invention can be when the user inputs gesture and carries out input operation, the target character of prediction user wish input, and show the guide tracks of the target character dope, and when the track of the gesture of user's input conforms to guide tracks, the target character that input prediction goes out.Wherein, the user can input gesture on Touch Screen, also can operate cursor input gesture, the not special restriction of the present invention.
The target character that the present invention carries can be word, numeral or symbol etc., but the present invention is not as limit; The guide tracks that the present invention carries is the track of required input in the time of will wanting input character.
Following elder generation is that the guide tracks that provides of the present invention illustrates System Operation of the present invention with the system architecture diagram of auxiliary gesture input with Fig. 1.As shown in Figure 1, system of the present invention contains track capturing module 110, character judge module 120, track processing module 130, track display module 140, track comparing module 150 and character load module 160.
Track capturing module 110 is responsible for when gesture is transfused to, the track of the gesture that lasting seizure is transfused to.
The track that character judge module 120 is responsible for instantly capturing according to track capturing module 110 judges corresponding target character.In the present invention, when character judge module 120 carried out the judgement of target character, the track that track capturing module 110 captures instantly was called as " start track ".
If character judge module 120 hunts out a plurality of characters that conform to according to start track, character judge module 120 usually can be by wherein selecting a character as target character.Generally speaking, character judge module 120 can be according to parameter select target characters such as the accumulative total input number of times of the input habit of user's gesture, each character of being judged out, front and back characters, but character judge module 120 is not limited with above-mentioned by the mode of select target character in a plurality of characters.
In the present invention, what is particularly worth mentioning is that, character judge module 120 is after judging target character, can suspend the track judgement target character that capture follow-up according to track capturing module 110, judge in the technology of target character with existing track according to gesture, after waiting for that gesture is completed, just the complete trajectory according to gesture judges that the mode of target character is different.
if character judge module 120 is after judging target character, just suspend the judgement target character, character judge module 120 can be after track capturing module 110 captures the start track of fresh character, restart to judge target character, or at the track comparing module 150 judgement track capturing module 110 follow-up tracks that capture (in the present invention, after character judge module 120 is judged target character, the track that track capturing module 110 captures is called as " track continues ") when not conforming to the obtained guide tracks of track processing module 130, with start track and the track that continues as new start track, and rejudge target character according to new start track.
The guide tracks of the target character that the responsible reading character judge module 120 of track processing module 130 is judged.The guide tracks that track processing module 130 is read normally with the length of guide tracks, trend, turning point, turnover direction, even and the mode of the track attributes such as angle between transverse axis or Z-axis store, but the guide tracks that the present invention carries is not stored in the mode of track attribute and is limited, for example, also can be directly store guide tracks etc. in the mode of the trajectory diagram of gesture.
Due to guide tracks except storing in the mode of trajectory diagram; normally with the mode record of track attribute; therefore; track processing module 130 is after reading out the track attribute of guide tracks; can produce trajectory diagram according to the track attribute of guide tracks; the track that the represented track of the trajectory diagram that is produced can be transfused to the gesture of expression target character is similar, and this track is guide tracks.
The responsible position of start track on the display screen (not shown) that captures according to track capturing module 110 of track display module 140 shows the guide tracks that track processing module 130 is obtained in display screen.
Then explain orally operation system of the present invention and method with an embodiment, and Fig. 3 a method flow diagram of guide tracks with auxiliary gesture input that provide of the present invention is provided.In the present embodiment, suppose test system application the present invention that the user uses, but the present invention is not limited to be applied in test system.Wherein, the test system of user's use is to carry out input operation by Touch Screen.
Do in test system when answering as the user, if want input alphabet " L ", Touch Screen can provide the gesture (step 301) of user's input alphabet " L ".In the present embodiment, user's gesture can first move from top to bottom, then transfers to from left to right and moving, and so just completes the input of the gesture of letter " L ".
Input in the process of gesture above-mentioned user, track capturing module 110 can constantly catch the track of the gesture that the user inputs, character judge module 120 can capture track capturing module 110 track of the gesture that the user inputs instantly as start track 410, and according to the start track 410 corresponding target characters (step 310) of judgement.In the present embodiment, if start track 410 is as shown in Fig. 4 a, be track from top to bottom, character judge module 120 can be according to the track characteristic of start track, for example, there is no the track characteristics such as turning point from top to bottom,, the target character of judgement user wish input may be " B ", " D ", " H ", " K ", " L ", " M ", " N ", " P ", " R " or letters such as " U ", suppose character judge module 120 at last according to the parameters such as accumulative total input number of times of user's input habit, above-mentioned each letter, the judgement target character is letter " N ".
After character judge module 120 was judged corresponding target character (step 310) according to start track 410, track processing module 130 can read the guide tracks 420 (step 320) of target character.In the present embodiment, the guide tracks 420 that track processing module 130 reads is the track of input alphabet " N ", namely first moves from top to bottom, and then wraparound starting point changes by the upper left lower mobile to the right, vertically moves from bottom to top at last.
After track processing module 130 read the guide tracks 420 (step 320) of target character, track display module 140 can be according to the position display guide tracks 420 (step 350) of start track 410.In the present embodiment, namely show the track of the gesture of expression input alphabet " N ", as shown in Fig. 4 a.
If track display module 140 is except showing guide tracks 420, show in addition start track 410, track display module 140 can use the line style different from shown start track 410 to reach or color demonstration guide tracks 420, for example, track display module 140 can use solid line to show start track 410, and makes with dashed lines show guide tracks 420.
In practical application, after track processing module 130 reads the guide tracks 420 (step 320) of target character, track display module 140 is front according to the position display guide tracks 420 (step 350) of start track 410, track processing module 130 can also be as shown in the flow process of Fig. 3 b, the size of the guide tracks 420 that convergent-divergent is read makes the size of guide tracks 420 and start track 410 after convergent-divergent meet certain proportion (step 332).In the present embodiment, track processing module 130 can zoom to the size identical with start track with guide tracks 420.
It is same after track processing module 130 reads the guide tracks 420 (step 320) of target character, track display module 140 is front according to the position display guide tracks 420 (step 350) of start track 410, and track processing module 130 can also be adjusted guide tracks 420 to the position (step 336) that conforms to start track 410.In the present embodiment; suppose that the gesture that the user inputs is not crooked; therefore; track processing module 130 does not need to rotate guide tracks 420, so, the position that 130 of track processing modules need to be shown with adjustment guide tracks 420; make guide tracks 420 and the start track can be overlapping as far as possible; so, track display module 140 is when showing guide tracks 420, and the part track of guide tracks 420 can be overlapping with start track.
Continue to get back to Fig. 3 a, after the position display guide tracks 420 (step 350) of track display module 140 according to start track 410, track comparing module 150 can judge continue track 450 and the guide tracks 420 of gesture that track capturing module 110 catches whether conform to (step 360).In the present embodiment, suppose that track comparing module 150 can be as shown in Fig. 4 b, produce comparison regional 430 according to guide tracks 420, judge so as to whether exceed comparison regional 430 by the track 450 that continues whether the track 450 that continues exceeds guide tracks 420 certain distances, and then judge whether the track 450 that continues conforms to guide tracks 420.
because being actually, the user wants input alphabet " L ", so the gesture that the user inputs can be after moving from top to bottom, turnover is for moving from left to right, therefore, when the user begins gesture to move from left to right, the gesture that the user inputs also can not surpass regional 430 scopes that contain of comparison, along with user's gesture continues to move right, the track 450 that continues that track capturing module 110 captures can exceed regional 430 scopes that contain of comparison, as shown in Fig. 4 b, this expression track 450 that continues exceeds guide tracks 420 certain distances, so, track comparing module 150 just can be judged the track 450 that continues and not be inconsistent with guide tracks 420.
Then, character judge module 120 can be with start track 410 with the track 450 that continues (when namely the user is with gesture input target character, the track of the character that the not input that track capturing module 110 captures is instantly completed) as new start track 490 (step 380), and according to the new start track 490 corresponding new target characters (step 310) of judgement.In the present embodiment, suppose character judge module 120 according to the track characteristic of new start track 490, namely from top to bottom, from left to right moving direction after turnover, the target character that judgement makes new advances is letter " L ".
After judging corresponding new target character (step 310) according to new start track 490 at character judge module 120, track processing module 130 can read the guide tracks 460 (step 320) of new target character, the guide tracks 460 (step 350) that track display module 140 is can be according to the position display of new start track 490 new is as shown in Fig. 4 c.In the present embodiment, because the user wants input alphabet " L " really, therefore, suppose that the user completes the input of the gesture of letter " L " according to new guide tracks 460, as shown in Fig. 4 d.
After track display module 140 guide tracks 460 (step 350) new according to the position display of new start track 490, track comparing module 150 can judge gesture that track capturing module 110 catches new continue track 470 and new guide tracks 460 whether conform to (step 360).In the present embodiment, because the user completes the input of the gesture of letter " L " really according to new guide tracks 460, within track comparing module 150 can judge that the track 470 that continues that makes new advances all drops on new comparison zone 480, represent that the new track 470 that continues remains in certain distance with new guide tracks 460, therefore, track comparing module 150 can judge that the track 470 that continues that makes new advances conforms to new guide tracks 460, character load module 160 just can be inputted target character, namely input alphabet " L ".So, the user just can complete the input of target character by the shown guide tracks of the present invention, avoids producing because gesture is correct not the misjudged situation of input.
In sum, difference between the present invention and prior art is that it has after the start track judgement target character according to gesture as can be known, the guide tracks of display-object character, when the track that continues of gesture conforms to guide tracks, the technological means of input target character, relying on this technological means can solve the existing use touch of prior art interface input character has the problem of higher False Rate, and then reaches the technology effect of the speed that improves the gesture input.
Moreover, the method of guide tracks with auxiliary gesture input that provide of the present invention, can be implemented in the combination of hardware, software or hardware and software, also can be in computer system realize or realize with the dispersing mode that different assemblies intersperse among some interconnected computer systems with centralized system.
