Abstract
The invention provides a gesture method for controlling screen zooming. A mobile terminal is taken as gesture input equipment and is used for obtaining coordinate information of the finger in real time; the coordinate data is processed and analyzed to determine the control on screen enlarging or narrowing; the rotating angle of the finger is recorded to control the zooming ratio; parameters are sent to an application control interface to realize the zooming control on the screen by one single finger. The algorithm is simple to realize, good in operation experience, and can be widely applied to the applications needing zooming control of the mobile terminal.
Description
Technical field
The present invention relates to a kind of mobile device touch-screen that utilizes as input equipment, the gesture behavior of human body is identified to control to the method for screen-picture convergent-divergent.
Background technology
Along with development and the touch screen handheld device of infotech are day by day universal, the application software based on mobile terminal has huge market and development prospect.Good application software of mobile terminal should have good interaction characteristic, improves user's experience.In these application, often there is the picture that need to carry out convergent-divergent control, such as electronic chart, picture, scene of game etc.User need to use zoom function to reach optimum experience, for example, with the zoom function of map, find fast own position or check the detailed geographical location information in certain region.In application, use at present the mode of multi-point touch, during two above contact screens of finger, as shown in Figure 1A, slide and amplify picture laterally, display frame information in further detail, as shown in Figure 1B, dwindles picture while sliding to the inside, show wider.This gesture operation mode meets user to amplifying the fundamental sensation dwindle, but also has certain limitation, needs two finger manipulation pictures, and for example user may only have the finger can operating handset when outdoor application, to operation, has brought inconvenience.Some application have added convergent-divergent control group, have solved the problem of single finger manipulation, but have reduced operating experience, to operation, make troubles.
Summary of the invention
The technical problem to be solved in the present invention is with singly referring to realize screen scaling, meanwhile, does not affect operating experience.
In order to achieve the above object, technical scheme of the present invention has been to provide a kind of gesture method of controlling screen-picture convergent-divergent, it is characterized in that, step is:
Step 1, with single finger, on touch-screen equipment, according to the direction of arrow, clockwise rotate or rotate counterclockwise;
Step 2, when finger contact touch screen, by touch-screen input equipment physical layer interface, obtain current gesture touch-control pixel coordinate, judge whether current contact is to contact for the first time touch screen, if so, enters step 3, if not, enters step 4;
Step 3, calculate current gesture touch-control pixel with respect to the angle of screen mid point, using this angle as touch-control angle last time, return to step 2;
Step 4, calculate current gesture touch-control pixel with respect to the angle of screen mid point, by this angle and touch-control angle contrast last time, according to the situation of change of angle, judge that current finger is for clockwise rotating or rotating counterclockwise, clockwise rotate with to amplify picture commands corresponding, rotate counterclockwise with to dwindle picture commands corresponding, or, clockwise rotate with to dwindle picture commands corresponding, rotate counterclockwise with to amplify picture commands corresponding; Meanwhile, calculate the anglec of rotation, different picture scaling corresponding to the anglec of rotation;
The present invention has higher accuracy, solves the convergent-divergent interaction problems of conventional screen picture, provides a kind of operating experience better man-machine interaction mode, and it has realizes the advantages such as simple, operating experience is better.

Embodiment
For the present invention is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
The invention provides a kind of gesture method of controlling screen-picture convergent-divergent, the steps include:
Step 1, by single finger direction according to arrow on touch-screen equipment, clockwise rotate (as shown in Figure 2 A) or rotate counterclockwise (as shown in Figure 2 B);
Step 2, when finger contact touch screen, by touch-screen input equipment physical layer interface, obtain current gesture touch-control pixel coordinate, judge whether current contact is to contact for the first time touch screen, if so, enters step 3, if not, enters step 4;
Step 3, calculate current gesture touch-control pixel with respect to the angle of screen mid point, using this angle as touch-control angle last time, return to step 2;
Step 4, calculate current gesture touch-control pixel with respect to the angle of screen mid point, by this angle and touch-control angle contrast last time, according to the situation of change of angle, judge that current finger is for clockwise rotating or rotating counterclockwise, clockwise rotate with to amplify picture commands corresponding, rotate counterclockwise with to dwindle picture commands corresponding, or, clockwise rotate with to dwindle picture commands corresponding, rotate counterclockwise with to amplify picture commands corresponding; Meanwhile, calculate the anglec of rotation, different picture scaling corresponding to the anglec of rotation;
Claims (1)
1. a gesture method of controlling screen-picture convergent-divergent, is characterized in that, step is:
Step 1, with single finger, on touch-screen equipment, according to the direction of arrow, clockwise rotate or rotate counterclockwise;
Step 2, when finger contact touch screen, by touch-screen input equipment physical layer interface, obtain current gesture touch-control pixel coordinate, judge whether current contact is to contact for the first time touch screen, if so, enters step 3, if not, enters step 4;
Step 3, calculate current gesture touch-control pixel with respect to the angle of screen mid point, using this angle as touch-control angle last time, return to step 2;
Step 4, calculate current gesture touch-control pixel with respect to the angle of screen mid point, by this angle and touch-control angle contrast last time, according to the situation of change of angle, judge that current finger is for clockwise rotating or rotating counterclockwise, clockwise rotate with to amplify picture commands corresponding, rotate counterclockwise with to dwindle picture commands corresponding, or, clockwise rotate with to dwindle picture commands corresponding, rotate counterclockwise with to amplify picture commands corresponding; Meanwhile, calculate the anglec of rotation, different picture scaling corresponding to the anglec of rotation;
Step 5, the amplification picture commands that step 4 is obtained or dwindle picture commands and picture scaling imports in the picture convergent-divergent control interface of touch-screen equipment operating system as parameter, complete picture bi-directional scaling.
