Embodiment
Describe the present invention below in conjunction with accompanying drawing and specific embodiment, but not as to qualification of the present invention.
As shown in Figure 1, be the structural drawing of self-defined virtual keyboard system of the present invention.This self-defined virtual keyboard system is applied to portable terminal, is used for the button on the dummy keyboard of portable terminal is carried out freely defining, and portable terminal comprises mobile terminal of touch screen, has the terminal near the screen of identification, and self-defined virtual keyboard system 10 comprises:
Button is provided with module 101; Be used for the button of dummy keyboard is carried out self-defined setting, like newly-built one button that gets into certain application or with the position of button, shape; In size and the pattern style one or more carry out effective record, and are stored in the block of memory 104;
Identification respond module 102 connects button module 101 is set, and is used to read button module 101 button after self-defined is set, and accurately discern, respond;
Correction module 103 connects button module 101 is set, and the mistake that is taken place when being used for that button is provided with module 101 user-defined press keys is judged and corrected.
The dummy keyboard of mobile terminal of touch screen is through self-defined virtual keyboard system 10 user-defined press keys.
Further; Each button on the dummy keyboard all is independently, and button is provided with the position that module 101 can free definition push key, shape; Size and pattern style, can also make the user on dummy keyboard by the self-defined button of the hobby of oneself to get into certain concrete application.
Further, when button is provided with module 101 user-defined press keys, if overlap on two key positions, cover or function re-defines etc., correction module 103 can prompting is wrong be also corrected.
The principle of work of the touch-screen of mobile terminal of touch screen mainly is that finger or other object touch the touch-screen that is installed in the display front end, and the touch detecting apparatus of mobile terminal of touch screen detects user touch location, sends touch screen controller then to; Touch screen controller receives touch information from touch detecting apparatus, and (X Y), gives the processor of mobile terminal of touch screen again and handles to convert it to contact coordinate.(X Y) is main key information to contact coordinate.
The setting of button on the dummy keyboard is comprised the position of button, shape, size and pattern style etc.For accurate recording, need bigger storage space and hardware resource to each button.For reducing the use of storage space and hardware resource; The method that adopts is to regard each button as a simple structure; Comprising key information have: X, Y (position of button), shape (shape of button); Size (size of button), style (the pattern style of button) or the like attribute information.Wherein, every comprises corresponding concrete setting again.(X Y) is the coordinate of key icon left upper apex, can locate button through this coordinate in the position of button.The coordinate of definition push key icon left upper apex is the positional information of button, and reason is to form the recognizable set of button jointly for the big or small size with the button of following definition, specifically how to utilize this scope identification button hereinafter to set forth in detail.The shape shape of button is used for the shape of area definition button, the different different shape informations of shape value storage, and the shape of button comprises multiple shapes such as square, triangle, circle.As button is set is when square, the value of shape is 0, button is set when circular, and the value of shape is 1, and when button being set being triangle, the value of shape is 2 or the like.The big or small size of button can comprise two element a and b.Wherein, a is the absolute value of the difference of the minimum and maximum horizontal ordinate X of key icon on the screen coordinate system x direction of principal axis, and b is the absolute value of the difference of the minimum and maximum ordinate Y of key icon on the screen coordinate system y direction of principal axis.Big or small a through button like this, (X Y) just can judge the scope of this button in the position of b and button; So that in identification respond module 102, use, shown in Fig. 2 a, the recognizable set of this button is exactly from left upper apex (X; Y) to the summit, bottom right (X+a, Y-b).The pattern style of button can comprise the color of button, the pattern of button, and also can add pattern definition through oneself is button style or the like, and these all need pre-deposit in the block of memory 104, when being provided with, calls to supply the user to select.
When button is provided with module 101 position of button is set; At first get into the key position option is set, finger drags the position of key icon to anticipation then, and at this moment touch detecting apparatus detects user touch location and sends touch screen controller to; Touch screen controller receives touching position information; And with it convert to contact coordinate (X, Y), the coordinate of the reposition of promptly setting.Button is provided with the new contact coordinate that module 101 obtains touch screen controller, and (X, Y) the former coordinate of replacement and depositing in the structure of corresponding button has promptly obtained the reposition of this button.When getting into when comprising the operation interface of this button next time, identification respond module 102 can visit block of memory 104 according to new this button of coordinate initialization, button will appear at new position.
The various possible shape of button has pre-deposited in the block of memory 104; When button is provided with module 101 shape of button is set; Only need that each shape is taken out tabulation of formation from block of memory 104 and supply the user to select, the shape with the setting of the record of the shape item in the structure of corresponding button after the chosen also deposits block of memory 104 in.Button for example is set is when square, the value of shape is 0, button is set when circular, and the value of shape is 1, and when button being set being triangle, the value of shape is 2 or the like.Thereby when the initialization button, generate difformity then through the value of judging shape.For simplifying the identification and the response process of button; The recognizable set of each button is reduced to the regular circumscribed rectangle of a key shape; Coordinate through to two end points in upper left and bottom right of current contact coordinate and this rectangle compares; Judge current contact whether in the recognizable set of this button, thereby judge whether to excite this press key message.So the magnitude range of each key icon also need be recorded into block of memory 104 in advance.Like an oval-shaped key icon, the initial range that defines it for (a, b), so, this two length of side is respectively a, the scope of the boundary rectangle of b is exactly this oval recognizable set, shown in Fig. 2 b.The button of a star and for example, the initial range that defines it is the length of side of boundary rectangle, shown in Fig. 2 c.With the method for circumscribed rectangle definition push key recognizable set, can reduce the operand of processor greatly like this, save a large amount of memory headrooms.
The size that button is set is exactly to each key icon initial range (a, change b).Idiographic flow is to get into the button size options is set; Finger drags the position of the bottom right end points of key icon to anticipation; At this moment touch detecting apparatus detects user touch location and sends touch screen controller to, and touch screen controller receives touch information, and converts it to contact coordinate (X; The coordinate of the reposition of Y), promptly setting.Button is provided with the position of new contact coordinate that module 101 obtains touch screen controller and corresponding button, and (X Y) does poorly, and taking absolute value, (A, B), (A B), deposits the structure of corresponding button in to the new button magnitude range that promptly obtains.The recognizable set information of button is exactly to be made up of jointly the positional information of button and the size information of button.
Button is provided with module 101 and on dummy keyboard, has set positional information for each button, promptly the position coordinates of left upper apex (X, Y) with the expression press key range virtual rectangle two length of sides (a, b).When finger or other object touch touch-screen; Touch detecting apparatus senses touch position also sends touch screen controller to, and touch screen controller receives touch information, and to touch information be converted to new contact coordinate (x '; Y '); Discern respond module 102 and carry out a series of judgements this moment, to determine whether having triggered certain key information, discerns corresponding key with this.Determination methods is to obtain new contact coordinate (x ', y ') whether in the recognizable set of certain button by each button of graded traversal, begins to seek the button that current operation interface exists successively and judge to the lower right of screen coordinate system like the upper left side from screen coordinate system: (establish this key position information earlier and be (X when traversing first button; When Y), size information is (a, b)); Judge earlier (x '; Y ') whether the upper left end points of this button recognizable set (X, lower right Y) judge again (x '; Y ') end points (X+a whether in the bottom right of this button recognizable set; Y-b) upper left side judges that just (x ', y ') is whether in the button recognizable set of this button.If set up, then explanation " keydown " at this moment is in this presses key range, and promptly this button is activated, and then the response associative operation.If be false, then seek next button successively downwards, continue to judge.After having judged that last button also is false, explain that " keydown " of this moment is useless operation, do not do any response.
Because the function of the former button of dummy keyboard configures, the response that identification respond module 102 realizes newly-increased button.In order to discern the different responses corresponding with distinguishing different key, its method is in the structure of button, to increase attribute of function, and each function item writes down the function of corresponding button, just writes down the entry address information of corresponding program.As when the function of certain button is set, select to get into corresponding concrete application by the user, to click then and preserve, this moment, program was saved to the function item with concrete path, got into the inlet of corresponding application program by function item record.Like this, identification respond module 102 through calling the function item of the corresponding button of inquiry, can directly get into corresponding concrete application when this button of response.
Because the degree of freedom of definition push key is quite big among the present invention, so variety of issue can take place during definition.For example, but the recognizing site of a button of definition with another definition push key overlap or cover, at this moment when clicking the overlapping region of two buttons, discern respond module 102 and will produce variety of issue, even can cause deadlock or the like.For the situation that two buttons overlap or cover, the similar process of solution and identification button can travel through relatively in certain sequence through the button in the place operation interface when setting button and judge.Because the recognizable set of each button predefined is perhaps defined by the user again, is recorded in the block of memory 104.Key position information like new settings be (x, y), size information be (c, d), the scope of knowing this button for the left upper apex of button from then on (x, y) to the summit, bottom right (x+c, y-d).So being the upper left side from screen coordinate system, determination methods begins to do comparison with the information of each button recognizable set successively to the lower right.As first button range information relatively be (x ', y ') and (x '+a, y '-b), then judge (the x of new key information the first time; Y) and (x+c, y-d) whether (x ', y ') to (x '+a; In the scope of y '-b), judge just whether the recognizable set of two rectangles has common factor, occur simultaneously if exist; Explain that these two button occurrence positions are overlapping, report an error, compare otherwise seek next button successively; Until having traveled through all buttons, do not manifest if all occurrence positions is overlapping, explain to define successfully.
Also having kind of contingent mistake is the re-defining of function when new button is set, as defines a button that gets into newly-built multimedia message, but the last directionkeys correspondence of current processor is exactly the function that gets into newly-built multimedia message, at this moment, re-defining of function has just taken place.For this kind situation, be used for preserving the function item that gets into corresponding function or concrete application in the possible constructions body and compare.When new button of definition; Correction module 103 compares each button function item that function item and current operation interface exist successively, and if any identical with the entry address of the function item of certain button, then explanation has taken place to re-define; The notification processor processing that reports an error; As do not have identical with it function item, then the duplicate keys definition does not take place in explanation, i.e. the function of definition push key success.
As shown in Figure 3, be the present invention carries out self-defined setting to the button of dummy keyboard process flow diagram.This flow process comprises that step is following:
Step 301, the operation interface of the button of entering dummy keyboard;
Step 302 is opened button and is carried out self defining programm;
