Abstract
A touch screen zoom command method is characterized in that a judging program is set, a user makes a clockwise or anticlockwise track on a screen with a single point without leaving the screen, the judging program executes a screen image zooming command by judging the clockwise or anticlockwise command sent by the user. The touch screen zoom command method has the advantages that operation is facilitated and equipment cost can be lowered.
Description
[technical field]
The present invention is about a kind of command method of touch screen zooming image.
[background technology]
At present, the mobile phone with Touch Screen has become the main flow in market, it typically is the resistance touch screen that size is less, only accepts single-point touch.Moving about image, is all on screen, to draw straight line at present, respectively up and down, left and right picture straight line, represents mobile image or page turning backward forward.The conventional two point adopting consecutive click chemical reaction of its image scaling order represents to zoom in or out order.This kind of touch-control the Scale command method can not zoom in or out continuously, and inconsistent with the operation of computing machine, easily causes and obscures.For large-sized contact panel, be generally capacitance touch control screen, it can accept 2 touch-controls, can separately move and represent to amplify order with two contacts, and the mobile order that represents to dwindle is drawn close in two contacts.This kind of touch-control Zoom method is directly perceived, but multi-point touch screen price is slightly expensive, and must control two points, and one-handed performance is not very convenient.
[summary of the invention]
Technical matters to be solved by this invention is to provide a kind of command method of touch screen zooming image, and it is easy to operate.
For solving the problems of the technologies described above, the invention provides a kind of touch screen zooming command method, set a determining program, user utilizes the mode that single-point does not frame out on screen, to mark clockwise or counterclockwise track, thereby described determining program carries out by judging the clockwise or counterclockwise instruction that user sends the order that screen picture zooms in or out.
Compared with prior art, the present invention has following beneficial effect: single-point is realized the order that Touch Screen zooms in or out, easy to operate and be applicable to resistance touch screen, is beneficial to reduction equipment cost.
[accompanying drawing explanation]
Fig. 1 is the diagram of drawing clockwise track on screen.
Fig. 2 is the diagram of drawing counterclockwise track on screen.
[embodiment]
Consult shown in Fig. 1 and Fig. 2, the invention provides a kind of touch screen zooming command method, this screen scaling order utilizes the mode that single-point does not frame out on screen, to mark clockwise or counterclockwise track, is the order zooming in or out that the mode of clockwise or counterclockwise instruction is carried out screen picture by what set that a determining program judges that user marks.
Described judgement formula conventionally need arrange one and judge formula, and what described judgement formula utilized that coordinate points that track that user marks on screen produces judges that user sends is clockwise instruction or instruction counterclockwise.This creation most preferred embodiment is in the time judging that formula judges that drawn track result is clockwise instruction, determining program is carried out screen picture and is amplified instruction, and in the time judging that formula judges that drawn track result is counterclockwise instruction, determining program is carried out screen picture and is dwindled instruction; This creation another one embodiment is in the time judging that formula judges that drawn track result is counterclockwise instruction, determining program is carried out screen picture and is amplified instruction, and in the time judging that formula judges that drawn track result is clockwise instruction, determining program is carried out screen picture and is dwindled instruction.
Described touch screen zooming command method, specific embodiments comprises the steps:
One Touch Screen is provided;
The determining program that connects aforementioned Touch Screen is provided, and described determining program can read the coordinate points of user's stroke trajectory generation on Touch Screen;
The judgement formula that is arranged at determining program is provided, the trajectory coordinates point that described judgement formula can utilize determining program to read judges that the track that user marks is clockwise or counterclockwise, and the clockwise or counterclockwise track that determining program marks according to user realizes to Touch Screen the instruction that image zooms in or out.
Continue to consult shown in Fig. 1 and Fig. 2, describedly judge that formula is S=(X2-X1) * (Y3-Y2)-(Y2-Y1) * (X3-X2), executive mode is: when user draws track, can on X coordinate and Y coordinate, correspondingly produce some coordinate points, determining program can import to these coordinate points that produce successively and judge in the middle of formula and calculate, thereby what judge that user sends clockwise also or counterclockwise instruction is.It is specific as follows: in the time that user draws track clockwise on screen, determining program imports to Y1, Y2, the Y3 of coordinate points X1, the X2 of the X coordinate reading successively, X3 and Y coordinate to judge in formula and calculate, if what user marked at that time is clockwise track, the result of calculation that judges formula is S<0, if what user marked at that time is counterclockwise track, the result of calculation that judges formula is S>0.As aforementioned, the present invention is mentioned to two kinds of embodiment, the first embodiment be when determining program judge that user marks be clockwise instruction time, determining program is carried out screen picture and is amplified instruction, when being specifically the result of calculation that judges formula and being S<0, when determining program judge that user marks be counterclockwise instruction time, determining program is carried out screen picture and is dwindled instruction, when being specifically the result of calculation that judges formula and being S>0; The second embodiment be when determining program judge that user marks be counterclockwise instruction time, determining program is carried out screen picture and is amplified instruction, when being specifically the result of calculation that judges formula and being S>0, when determining program judge that user marks be clockwise instruction time, determining program is carried out screen picture and is dwindled instruction, when being specifically the result of calculation that judges formula and being S<0.
Described determining program reads coordinate points X1, X2, X3 and Y1, Y2, Y3 all by the identical time interval, and the time interval of each coordinate points that the determining program of this creation most preferred embodiment reads according to track that user draws is set to 0.01 second.If it should be noted that, the size of screen picture can not meet user's demand, only needs the instruction that screen is marked to clockwise or counterclockwise track can realize the object of the screen picture that further zooms in or out.
Touch screen zooming command method of the present invention discloses as above, but those of ordinary skill in the art still may carry out all replacement and modifications that does not deviate from spirit of the present invention based on teaching of the present invention and announcement.Therefore, protection scope of the present invention should be not limited only to the content that embodiment discloses, and comprises various do not deviate from replacement of the present invention and modifications, is present patent application claim and contains.
