Detailed Description
The gesture input method is realized in a software form on the intelligent terminal, and can be operated in various hardware devices, such as terminal devices of intelligent mobile phones, tablet computers, intelligent televisions, game machines and the like. For the most common GUI common operations of gesture input such as screen sliding or clicking, the intelligent terminal system or application has a default conventional processing mode, such as screen sliding or clicked item starting, long-press and double-click operation processing and the like. If handwriting input is to be directly performed on a desktop or other application interfaces, the key is to distinguish common gesture operation from stroke input. In embodiments of the present invention, if it is not determined that the gesture input is a text stroke input, it may be handled in a system or application default manner.
FIG. 2 is a diagram of an example of a gesture input device according to the present invention. The gesture input device in this embodiment includes an input unit 1, configured to receive gesture operation input, where the type of the gesture operation input may include a common gesture operation and a character stroke input; the recognition unit 2 is used for judging the type of gesture operation input according to the number and the characteristics of the contacts input by the gesture operation, and further recognizing characters corresponding to stroke tracks; and the execution unit 3 is used for executing corresponding processing according to the judgment result of the identification unit 2, if the character stroke input is judged, displaying the input stroke track on a screen interface, and performing corresponding processing on the stroke track, if the character corresponding to the stroke track is identified by the identification unit 2, performing corresponding processing according to the identified character, or directly storing the stroke track, if the stroke track is used as the original stroke remark of the current content, and when the content is checked next time, calling out the stored original stroke remark.
Further, the execution unit 3 may further include a retrieval module 31, configured to perform local retrieval or network retrieval using the identified text as a keyword, and present a matching result on a screen interface. Such as searching for the contents of contacts, short messages, applications, etc. of the local address book. If the current interface is a shopping application, keyword related item information or the like may be retrieved from a network database.
Considering that some users may be unaccustomed or unable to enter text by handwriting, or that the application does not require this functionality, it is desirable to mask the handwriting recognition mode. The intelligent terminal can also provide stroke recognition switch options, only when the stroke recognition switch options are detected to be started, the type of the gesture operation input can be judged by the recognition unit in the current interface window, and otherwise, the processing is carried out according to a system default operation instruction, such as screen sliding or clicking operation. This switch option may be system level, set in system preferences; or application level, in which the stroke recognition switch option is turned on. In addition, if the current common input mode is detected, double-finger handwriting can be automatically shielded, so that the user can input by handwriting through a single finger.
In this embodiment, for example, the intelligent terminal equipped with the touch screen is implemented, and double-finger handwriting is adopted, if the index finger and the middle finger can be used, the recognition unit detects that the number of the contacts is two, and the gesture features of the two contacts have consistency, it is determined that the character strokes are input. When a User uses two fingers to perform handwriting, the characteristics of the two fingers and the touch points of the touch screen have consistency, and the invention utilizes the consistency of the gesture characteristics to realize intelligent distinguishing of common gesture operations of double-finger handwriting and a Graphical User Interface (GUI for short). Like the zooming in and out of the double fingers in the common gesture operation, the distance between the two touch points is gradually and obviously increased or decreased, and when the double fingers are used for handwriting input, the relative positions of the two touch points are basically stable, and the distance is not obviously changed.
Fig. 3 is a schematic main flow chart of an example of the gesture input method of the present invention, which is implemented on a smart phone, and includes the following steps:
301. and the intelligent terminal receives gesture operation input on the touch screen. For example, the gesture operation input on the touch screen can be monitored in the applications of a system desktop, an application list, a short message list, a contact list or a lock screen of the intelligent terminal.
302. And determining whether the character strokes are character strokes according to the number and the characteristics of the contact points input by the gesture operation. Specifically, if the number of the contact points is two and the gesture characteristics of the two contact points are consistent, the character stroke input is judged. The preferred embodiment of the present invention is to use two-finger handwriting, but may also use three-finger handwriting, and the character stroke input is determined as long as the gesture features of a plurality of touch points are determined to have consistency. As shown in FIG. 4, which is a schematic diagram of the handwriting with two fingers according to the present embodiment, there are two contact points of the index finger and the middle finger, and the index finger on the left side can be used as the handwriting stroke track.
The consistency detection may specifically detect that the gesture movement distance of the first contact is within a first predetermined threshold (e.g. 60 pixels) and the distance between the two contacts is within a second predetermined threshold (e.g. 25 pixels) when the pressing of the second contact is detected within a first predetermined time (e.g. 0.2 seconds), and then the change in the distance between the two contacts is within a third predetermined threshold (e.g. 20 pixels) within a second predetermined time (e.g. 0.2 seconds), so as to determine that the gesture characteristics of the two contacts have consistency.
If the pressing of the second contact point is not detected within the first preset time, the operation of the GUI common gesture of the single finger is judged, and even if the pressing of the second contact point is detected later, the character stroke input is not triggered. Optionally, the gesture movement distance of the first contact point may be further defined, and if the first contact point has moved a longer distance (e.g., 60 pixels) when the second contact point is pressed, the text stroke input is also excluded and the normal gesture operation is performed.
Further, in order to distinguish the zooming gesture operation, such as the zooming operation, the two fingers are close to each other at the initial time, and the distance is increased after a certain time, so that the initial distance between the two contacts can be recorded when the two contacts are detected, the change difference between the current distance and the initial distance of the two contacts is detected in the gesture moving process of the two fingers, and if the change exceeds the preset threshold within the second preset time, the GUI common gesture operation is determined. Here, the second predetermined time cannot be set too long, otherwise the user feels a noticeable delay in the stroke display at the time of the two-finger handwriting, which is preferable within 1 second. In addition, in order to avoid delay caused by judging whether character stroke input needs a certain time, a lighter semitransparent stroke track can be displayed before the type cannot be determined by double-finger operation, after the type is determined subsequently, if the character stroke input is performed, the display of the stroke track (comprising the drawn semitransparent stroke track) is enhanced, and otherwise, the stroke track is eliminated.
A relatively simple consistency judgment method can also be adopted, and after two touch points are detected, if the distance change between the two touch points within a preset time is within a preset threshold value, the gesture characteristics of the two touch points are determined to have consistency. This also substantially distinguishes the most common two-finger zoom GUI operations.
303. If the character stroke is judged to be input, displaying the input stroke track on the screen interface, and carrying out corresponding processing on the stroke track. If any one of the two contact points is detected to be lifted and the two contact points are not detected to be pressed within the preset time, the character stroke input is finished, characters corresponding to the stroke track can be identified subsequently, local and/or network retrieval is carried out according to the identified characters, or the stroke track is directly stored.
The text stroke input may also be terminated upon detecting that both contacts have been lifted and that no two contacts have been detected to be pressed within a predetermined time. For the input of characters, for example, Chinese characters and words or English words generally require multiple continuous gesture operations to complete the input. If the interval between the ending time of one gesture operation input (when all the contact points are lifted) and the starting time of the next gesture operation input is within the set threshold value range (such as 1 second), namely two double-finger gesture operation inputs in quick succession can be determined to be the same group of gesture operation inputs.
If the difference between the distance between the two contact points when the input is finished and the distance between the two contact points when the input is started is smaller than a preset threshold value, recognizing characters corresponding to the stroke track, and performing local and/or network retrieval according to the recognized characters; otherwise, the subsequent processing is cancelled. Therefore, if a user wants to cancel the currently input characters in the handwriting process, the user can release the two fingers on the screen, so that the contact distance is increased to exceed the threshold value, the purpose of canceling the input is achieved, and the operation is very simple and convenient.
After the handwriting input is completed, the gesture movement track of any one of the two touch points can be used as the track of character stroke input, for example, the track of the touch point positioned on the left side or the lower side is selected as the track of stroke input. Or taking the average value of the gesture moving tracks of the two touch points as the track of character stroke input, averaging the coordinates of the two touch points at each moment in the handwriting process, and taking the average value coordinate track as the track of character stroke input.
After the character stroke input is finished, the component which obtains the focus in the current interface can receive and process the stroke track and/or the character recognized according to the stroke track. And if the currently focused component is a text edit box, inserting the character recognized according to the stroke track into the text edit box.
Or receiving and processing the stroke track and/or the character recognized according to the stroke track by a component closest to the handwriting starting position in the current interface. If the handwriting initiation point is in a picture content, the obtained stroke track is stored and associated with the picture. Thus, the original handwriting annotation of the picture can be realized. More flexibly, after the character stroke input is finished, processing mode options can be displayed, and the stroke track and/or the character recognized according to the stroke track are processed according to the selected processing mode options.
304. Otherwise, processing the gesture operation input in a default mode of a system or an application. If the input is judged to be the common GUI gesture operation input, the screen interface is made to slide in the corresponding direction, including sliding left and right or up and down, and clicking, double clicking, long pressing or zooming and the like are carried out.
In addition, in the embodiment, double-finger handwriting is mainly adopted, so that the accidents of two touch points are further analyzed. When a user clicks an icon or the like with a single finger, the user may touch the screen with other fingers inadvertently, which is usually very short, so that the gesture operation input may be processed in a default manner by the system or by the application if it is below a predetermined threshold (e.g. 5 pixels) at the end of the gesture operation input, according to the length of the track for detecting the second contact.
In addition, for a system which adopts a camera to recognize gesture operations, such as a smart television or a video game machine, different from the operation of a touch screen of a mobile phone, the gesture operations, such as selection, page turning and the like, can be performed by the action of the whole palm. Therefore, the mode of determining whether the touch points are character strokes or not is different according to the number and the characteristics of the touch points input by the gesture operation, the actual contact is avoided through the camera recognition, and the number of fingers in the gesture can be used as the number of the touch points. Specifically, the handwriting input can be performed by using the index finger. If one touch point is detected and the trajectory of the touch point moving in the predetermined time is greater than a predetermined threshold, the handwritten stroke input may be determined. And when the number of the contact points is detected to be zero, namely when the fingers are all retracted, finishing handwriting input.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention, and it is therefore to be understood that the invention is not limited by the scope of the appended claims.
