Description
Technical field
The present invention relates to the intelligent terminal field, relate in particular to a kind of man-machine interaction method and terminal.
?
Background technology
The screen of intelligent terminal such as mobile phone and panel computer is less, and when content was many, usually the form with multipage or tabulation represented, and the user can use finger to carry out the gesture operation input by touch-screen, as about or slide browsing content up and down.Many when number of pages, when tabulation is long, this operation poor efficiency consuming time, and be easy to generate mistakes and omissions.And by the mode of search box is provided, the user can enter the literal input pattern after clicking search box, carry out the input of literal by hand-writing input method or other input methods, terminal is carried out content retrieval according to the literal of input then, shows matching result, and this has made things convenient for the user to a certain extent.But it is still easy inadequately in operation, the user has to click search box, entering behind the input pattern could input characters, even need to put earlier to open menu, in menu, select to import after the search, search box has also taken screen interface in addition, and the user experience on the less intelligent terminal of screen is had certain influence.
Also having a kind of method is the first stroke of a Chinese character zone that limits a stroke input, and every detecting begins to import in first stroke of a Chinese character zone, all determine it is the strokes of characters input, and the gesture that begins outside zone input can be defined as sliding screen operation or clicking operation etc.This scheme need be carried out extra prompting, just can make the user notice the scope in first stroke of a Chinese character zone.
Summary of the invention
Based on the deficiencies in the prior art, primary and foremost purpose of the present invention is to provide a kind of man-machine interaction method, the type of Intelligent Recognition gesture operation input, thus make the user can directly on screen interface, carry out handwriting input, can operate and clicking operation by compatible sliding screen again simultaneously, can not cause and obscure.
Another object of the present invention is to provide a kind of terminal, the type of Intelligent Recognition gesture operation input, thus make the user can directly on the screen interface of terminal, carry out handwriting input, simultaneously again can compatible sliding screen operation and clicking operation.
For realizing above-mentioned each purpose, the present invention adopts following technical scheme:
The alleged man-machine interaction method of the present invention's first purpose comprises step: terminal receives the gesture operation input; Distinguish sliding screen operation, clicking operation and strokes of characters according to the track characteristic of described gesture operation input; If judge it is the strokes of characters input, then show the stroke track of input, and discern described stroke track corresponding character at screen interface, carry out respective handling according to the literal that identifies; Otherwise handle described gesture operation input by the mode of system or application defaults.
The terminal that the present invention's second purpose is alleged for man-machine interaction provides operation interface, comprising:
Input block is used to receive the gesture operation input, and the type of described gesture operation input comprises sliding screen operation, clicking operation and strokes of characters at least;

Below in conjunction with the drawings and specific embodiments the present invention is specifically described:
Description of drawings

Fig. 3 is the method flow synoptic diagram of definite gesture operation input type of one embodiment of the present of invention;
Embodiment
The man-machine interaction method that the present invention is alleged is realized with form of software on intelligent terminal, can be installed in the various hardware devices, for example terminal type equipment such as smart mobile phone, panel computer, intelligent television, game machine.For the input of the most frequently used gesture as sliding screen operation or clicking operation, intelligent terminal system or use default conventional processing mode is all arranged, as screen is slided, or start the project of being clicked, also have long by and double-click and handle etc.The difference of sliding screen operation and clicking operation is very big, obviously distinguishes easily, and key is that these two kinds of operations all might be obscured with stroke input generation.In embodiments of the present invention, if fail to judge that the gesture input is a strokes of characters, then can handle by system or application defaults mode.
Fig. 1 is the application example synoptic diagram of intelligent terminal of the present invention.Intelligent terminal in the present embodiment comprises input block 1, is used to receive the gesture operation input; Recognition unit 2 is used for the sliding screen of track characteristic differentiation operation, clicking operation and strokes of characters according to the gesture operation input of described input block 1 acquisition, judges that this input is a strokes of characters, or screen slip instruction etc., and discern stroke track corresponding character; Performance element 3, be used for carrying out respective handling according to the judged result of described recognition unit 2, if it is the strokes of characters input that described recognition unit 2 is judged, the stroke track that then shows input at screen interface, and after described recognition unit 2 identifies described stroke track corresponding character, carry out respective handling according to the literal that identifies, otherwise handle described gesture operation input by the mode of system or application defaults, as judgement is sliding screen operation, then make screen interface carry out the slip of respective direction, also can carry out specific sliding screen action by current application, as perhaps call in deleting etc.For clicking operation, default can start the project of being clicked, as opens load card of contact person etc.If do not click any bootable project, then can not carry out any operation.
But the gesture operation on the input block 1 general receiving terminal touch-screen wherein input, as about or slide up and down screen.At present portable terminal device all has been equipped with touch-screen, comprises capacitance plate or resistance screen, all needs to point usually or pen carries out the operation of contact.But the present invention is equally applicable to contactless gesture input, provide input mode if any intelligent television or video game machine based on camera, can be in the action of remote (about) identification gesture or whole body as 2 to 3 meters, thus realize operating as the content page turning accordingly or carrying out game control etc.
The type of gesture operation input can comprise strokes of characters input and screen slip instruction.Fundamental purpose of the present invention is exactly the type of Intelligent Recognition gesture operation input, is the strokes of characters input to distinguish input, or screen slip instruction.Usually the sliding screen of gesture is the comparatively single simple gesture operation of a kind of pattern, and the strokes of characters input is a kind of gesture behavior of complexity.Sliding screen gesture is generally up and down or the simple straight path of left and right directions, slides in respective direction to drive screen, and this also is a kind of simulation that physical world is experienced.And for alphabetic character, as English alphabet a, b, c or the like, the strokes of characters trajectory model of importing when hand-written is obviously different with sliding screen operation, therefore by the track characteristic of recognition unit according to the gesture operation input of input block acquisition, can discern the type of gesture operation input.
Further, if judge it is the strokes of characters input, the stroke track that then shows input at screen interface, allow the user can see the literal that oneself is imported in real time, and recognition unit carries out handwriting identification according to the stroke track that obtains, obtain carrying out respective handling again behind the recognition result, retrieve the content information that shows coupling then according to the literal that identifies as performance element.
Fig. 2 is the example process synoptic diagram of man-machine interaction method of the present invention, and the example that is embodied as with on smart mobile phone may further comprise the steps:
101, intelligent terminal receives the gesture operation input on the touch-screen.As can in system desktop, list of application, message list, contacts list or the screen locking etc. of intelligent terminal are used, monitoring the gesture operation input on the touch-screen.
102, the current application window of intelligent terminal is judged the type of this input according to the track characteristic of gesture operation input, determines it is the strokes of characters input, and still screen slides and instructs.The type of gesture operation input can also comprise clicking operation, and corresponding input trajectory is a point, is commonly used to select the element in the current interface, as starting the application of institute's clickable icon correspondence, or opens a certain the note of checking in the message list etc.
For the input of literal, as Chinese-character word-phrase or English word, need continuous repeatedly gesture operation just can finish input.If the interval (as 1 second) in the preset threshold scope of the start time of the concluding time of a gesture operation input and gesture operation input next time, twice promptly continuous fast gesture operation input can determine it is gesture operation input on the same group.As a Chinese character " wood " corresponding one group of gesture operation input when importing, comprise 4 quick continuous inputs, these 4 strokes belong to gesture operation input on the same group.Can include only a gesture operation input in certain one group of gesture operation input.
Can carry out real-time monitoring to the first stroke of one group of gesture operation input, the angle direction of line between the current point of the track of calculating gesture operation input and the starting point, and, judge the type of gesture operation input in conjunction with the screen glide direction that current interface allowed.If current interface allows screen to horizontally slip, and detect the angle (as 5 degree) within predetermined threshold value of described line and horizontal direction, then judge it is horizontal line, otherwise be the strokes of characters input.If current interface allows screen to slide up and down, and the angle that detects described line and vertical direction then judges it is vertical line within predetermined threshold value, otherwise be the strokes of characters input.If when handwriting input, tangible bending has taken place track like this, can be defined as the strokes of characters input.About said method also is applicable to and supports simultaneously and the interface of slide down screen.
Further, if the input of last gesture operation is judged as strokes of characters, and the interval that detects the start time of this gesture operation input and the concluding time that last gesture operation is imported is in preset range, promptly belong to gesture operation input on the same group, determine that then this gesture operation input also is a strokes of characters.Get final product complete input characters like this,, and need not again track characteristic have been carried out type classification as long as judgement time at interval.In the process that strokes of characters is imported continuously, carry out literal identification simultaneously, the textual list of show candidate, after acquisition is selected to confirm, definite literal that finally identifies.Can also comprise the phrase that obtains by association in candidate's the textual list, or the word that obtains from normal moveout correction etc.As user's handwriting input is " machine ", can comprise " air ticket " in the candidate list, and approximate word " phase " or the like, if selected " air ticket ", then with it as the literal that finally identifies, carry out follow-up processing, as search for the relevant network information, or open the application that to purchase the air ticket etc.
In the process that the gesture operation of the first stroke is imported, before determining that described gesture operation is input as strokes of characters, handle, as carrying out screen slip instruction by system default.If the length of the gesture operation track of the first stroke is 0, perhaps in a very little predetermined threshold value scope (as 1 pixel) then can be handled by default clicking operation earlier.
Further, if in the hand-written process of the first stroke, carried out sliding screen, when " buying " as handwritten Chinese character, write stage of horizontal line at the first stroke, screen has carried out horizontal slip, input phase behind turning point, being judged as is the stroke input, at this moment system can stop or cancel slip.Can carry out resilience as screen interface, show that stroke imports the interface when initial.In the input process of follow-up this Chinese-character stroke, screen interface can be fixed, and shows the track of stroke input in the superiors' stack.
Also do some optimization processes, as for simplified Hanzi, all from left to right, write from top to bottom with literal characteristics according to language.Therefore for the first stroke gesture operation be input as from right to left horizontal line or vertical line from bottom to top, can judge that all determining is sliding screen operational order.
As shown in Figure 3, recognition unit comprises according to the concrete steps of the sliding screen of track characteristic differentiation operation, clicking operation and the strokes of characters of described gesture operation input:
Whether the track of step 301, detection the first stroke gesture operation input earlier is horizontal line, vertical line or point, if not, carry out
Whether step 303, the continuous gesture operation input of detection have second input, if do not have, then carry out
Whether step 305, second gesture operation input of detection overlap with the track of the first stroke, if two track does not overlap, then step 306 judges it is the strokes of characters input, otherwise step 307 judges it is to slide screen operation or clicking operation, and handle accordingly.
Whether concrete if the first stroke is horizontal line (or vertical line) in one group of gesture operation input, second also is horizontal line (or vertical line) for example, and two positions overlap substantially, can judge less than predetermined threshold value according to the track distance.Determine that then this is continuous sliding screen operational order, twice sliding screen direction can be identical, also can be opposite.If preceding two do not overlap, then be defined as strokes of characters input, as Chinese character " two ", " in ", " river ", " already " or " king " etc.Overlapping can not appear in the stroke of normal words input in addition, therefore can simply judge, if preceding two coincidences then determine it is not the strokes of characters input yet.And the first stroke and second are a little, and the position overlaps substantially, then can determine it is double-click action in the clicking operation.
If the first stroke is horizontal line (or vertical line) in one group of gesture operation input, second is not horizontal line (or vertical line), and two track position does not overlap, and then can be defined as the stroke input.
If the first stroke is a little in the input of one group of gesture operation, and second continuous input arranged, and track be a little, then is defined as stroke input.This is not wait other operations because the general user can not slided screen at once after clicking operation, usually all need wait-for-response after the click, as starting a new window, wait and perception response institute's time spent will be more than the interval threshold of importing fast continuously that is provided with usually.
Special in addition, if the user wants to import Chinese character " ", can make the track and the horizontal direction angle of gesture operation input big, as 10 degree, like this according to above-mentioned method, the sliding screen that just can not be judged as has from left to right been operated, and during literal identification, can comprise " one " in the prepare word that such track obtains.
In sum, for one group of gesture operation input, when finishing for second, can judge the type of input usually.
If 103 judge it is the strokes of characters input, then show the stroke track of input, and discern described stroke track corresponding character at screen interface, carry out respective handling according to the literal that identifies.If not judging is before strokes of characters is imported, the stroke track that does not show input, then follow-uply determined that just this group gesture operation input is a strokes of characters, then can carry out replenishing fast drafting, to guarantee visual feedback timely to the stroke track that not have before to show.
Performance element can also comprise retrieval module 31, is used for carrying out this locality retrieval or network retrieval with the literal that identifies as key word, and matching result is presented on the screen interface.As retrieve the content such as contact person, note, application of local address list., current interface uses article that then can search key is relevant from network data base etc. if being shopping.
Except carrying out retrieval process, can also be used for input characters.Performance element can also comprise editor module 32, if the interface element of current acquisition focus is the text input module, editor module is inserted into the literal that identifies at the current cursor place of described text input module.During as editing short message, so just do not need to switch input method, directly can on screen, carry out handwriting input.In this manner, if occurred dummy keyboard on the interface, and clicking operation having taken place on dummy keyboard, then handled according to click, has not imported as stroke.
If 104 judge it is sliding screen operation or clicking operation, then handle, as make screen interface carry out the slip of respective direction by the mode of system or application defaults, about comprising or slide up and down, and click, double-click or long by etc. processing.Sliding in addition screen operation can also make performance element that current page is refreshed or loading content except screen slides.As the content of current interface topmost, slips that can't make progress again, but after receiving screen upwards slip is instructed, performance element can carry out refresh operation to the current page content, as obtaining up-to-date microblogging information from network and being presented at the page.If the content in the same current interface is at lowermost end, then screen slides to instruct and can load more contents in the current page tabulation.In some were used, screen slides to instruct also self-defining action, as in contact person or message registration tabulation, slided at a certain from left to right, then can carry out the action of calling.Operation except that the stroke input can be thought the processing of system or application defaults.
Consider that certain customers may be uncomfortable or can not the handwriting input literal, as not accepting basic character calligraph study etc.Perhaps use and need not this function, want to shield the handwriting recognition pattern.Intelligent terminal can also provide the switch option of stroke identification, only enabled stroke identification switch option, the current interface window just can be judged the type of described gesture operation input by recognition unit, otherwise slides or clicking operation is handled by system default operational order such as screen.This switch option can be system-level, is provided with in system preference; Also can be application layer,, inherit from the parent of a specific support gesture operation input Intelligent Recognition, then think to have opened switch option as an application window (Activity) by being used for unlatching.
When another embodiment of the present invention is mainly described further optimization and solved the first stroke and begin to import, be difficult to distinguish the gesture operation input type, and cause producing the problem that is not inconsistent with user view.Be that the stroke of point is input as example at first to distinguish the clicking operation and the first stroke of a Chinese character.A lot of Chinese characters,, are handled as clicking operation by system if when input point as " Chinese ", " word ", " capital " or the like all to put as the first stroke, then can cause some maloperations, as starting application etc., influence user experience.
In the technical scheme of present embodiment, the default process of clicking operation is suitably postponed, be slightly larger than the predetermined interval threshold value of hand-written continuous input time delay.Detect the one click operation as terminal, but do not handle this operation by default mode immediately, but detect in follow-up 1 second, whether to also have continuous gesture input.If there be not second input, then handle this operation by default mode, otherwise then judge second track whether with the overlapping of last time, if overlap, then handle this operation by default mode as double click operation, if do not overlap, then be defined as the stroke input, and show the stroke track of last and this input.So just can when being point, the first stroke of a Chinese character not produce maloperation.Present two aspects of described delay body, the one, the delay of sliding screen operation or clicking operation to be handled, another is before failing to determine to be the stroke track, postpones to show stroke on screen, because the time that is postponed is very short, can not impact user experience.
The another one example is the screen locking interface, realizes hand-written going directly at the screen locking interface of intelligent terminal, as the laggard line search of input characters, perhaps directly enters the application of literal correspondence, and is more convenient like this.During some screen lockings is used, if the course length of sliding reaches a threshold value, then can release, otherwise can release, this release mode does not limit the zone of slip release, does not limit the shape (can not be straight line) of track yet.If carry out handwriting input, need to solve the problem of obscuring of release slide and handwriting input at such screen locking interface.Implementation herein also is to adopt the method that postpones processing, and is concrete, if promptly detect one time slide at the screen locking interface, but do not handle this operation by default mode immediately, but detects whether also had continuous gesture input in follow-up 1 second.If there be not second input, then handle this operation (,, can only show to touch animation effect) if the course length of slide is not enough as release by default mode, second continuous input arranged else if, then handle by the stroke input.Stroke to input carries out literal identification, and after input was finished, the screen release showed according to the matching result that literal retrieved that identifies.As show the contact person of being mated with this literal in the address list.
Above disclosed only is preferred embodiment of the present invention, can not limit the present invention's interest field certainly with this, and therefore the equivalent variations of being done according to the present patent application claim still belongs to the scope that the present invention is contained.
