Abstract

The invention discloses a gesture method used for a mouse. The method comprises the following steps of: detecting whether a first gesture is executed or not, wherein the first gesture refers to pressing the right button of the mouse; detecting whether a second gesture is executed or not, wherein the second gesture refers to keeping pressing the left button of the mouse and simultaneously sliding the mouse; recording the original coordinate of a mouse pointer at the moment of clicking the mouse and recording the real-time coordinate of the mouse pointer in the process of sliding the mouse; determining the magnitude of a first distance between the current real-time coordinate of the mouse pointer and a preset coordinate and the magnitude of a second distance between the original coordinate and the preset coordinate, wherein the preset coordinate is a central symmetry coordinate of the original coordinate relative to the central point of a projection screen; and if the first distance is greater than the second distance, amplifying the current display image, otherwise, reducing the current display image. By utilizing the gesture method used for the mouse, a function of scaling the current display image can be realized only through the mouse, and the convenience for control is enhanced.

Description

A kind of gesture method that is used for mouse

Technical field

The present invention relates to a kind of gesture method that is used for mouse, relate in particular to a kind of gesture method that is used for mouse that strengthens operation ease.

Background technology

Traditional click that only is confined to display object of controlling to projector use mouse does not have and only uses mouse that the convergent-divergent that carries out of display object is controlled, and uses to have certain limitation.

Summary of the invention

The object of the present invention is to provide a kind of gesture method that is used for mouse that can realize the zoom action of display object through mouse.

For realizing above-mentioned purpose, the said gesture method that is used for mouse is characterized in, comprise,

Step 1: detect whether carried out first gesture, said first gesture is not put for pinning right mouse button;

Step 2: detect and whether carried out second gesture; Said second gesture is not put and the while sliding mouse for pinning left mouse button; Be recorded in the origin coordinates of mouse pointer constantly of clicking the mouse, and the real-time coordinate of mouse pointer in the process of record sliding mouse;

Step 3: judge the size of the real-time coordinate of current mouse pointer and first distance between the preset coordinate and the second distance between said origin coordinates and the preset coordinate, wherein said preset coordinate is the center symmetric coordinates of said origin coordinates with respect to the projection screen central point; If said first the distance greater than second distance, execution in step four; Otherwise, if said first the distance less than second distance, execution in step five;

Step 4: produce one first instruction, said first instruction is for amplifying current displayed image; And,

Step 5: produce one second instruction, said second instruction is for dwindling current display image.

Preferably, amplification or the scale down to current display image satisfies:

wherein; D1=sqrt ((x-400) * (x-400)+(y-300) (y-300)), d2=sqrt ((X-400) * (X-400)+(Y-300) (Y-300)); Origin coordinates be (x, y), in real time coordinate be (X, Y).

Beneficial effect of the present invention is, adopts the said gesture method that is used for mouse, can realize only carrying out through mouse the zoom function of current display image, has increased the convenience of controlling.

Fig. 2 is the synoptic diagram that is used for the gesture method of mouse of the present invention.

Embodiment

Below in conjunction with accompanying drawing the present invention is further specified.

Fig. 1 is the process flow diagram that is used for the gesture method of mouse of the present invention, and is as shown in Figure 1, and the said gesture method that is used for mouse is characterized in, comprise,

Step 1: detect whether carried out the first gesture S1, said first gesture is not put for pinning right mouse button;

Step 2: detect and whether carried out the second gesture S2; Said second gesture is not put and the while sliding mouse for pinning left mouse button; Be recorded in the origin coordinates of mouse pointer constantly of clicking the mouse, and the real-time coordinate of mouse pointer in the process of record sliding mouse;

Step 3: judge the big or small S3 of the real-time coordinate of current mouse pointer and first distance between the preset coordinate and the second distance between said origin coordinates and the preset coordinate, wherein said preset coordinate is the center symmetric coordinates of said origin coordinates with respect to the projection screen central point; If said first the distance greater than second distance, execution in step four; Otherwise, if said first the distance less than second distance, execution in step five;

Step 4: produce and carry out the first instruction S4, said first instruction is for amplifying current displayed image; And,

Step 5: produce and carry out the second instruction S5, said second instruction is for dwindling current display image.

Contrast accompanying drawing 2 is explained the ratio that contents of the present invention and amplification are dwindled below, and as shown in Figure 2, for the display screen of a 800x600, the coordinate of its central point O is (400; 300), when carrying out said second gesture, the A point that left mouse button is clicked is as starting point; Origin coordinates be made as (x, y), then this origin coordinates is the AA point with respect to the center symmetric points of said central point O; With as preset coordinate, preset coordinate is (800-x, 600-y)) under the situation shown in Figure 2.In the process that mouse slides, and the real-time coordinate of mouse pointer and preset coordinate (800-x, the distance between 600-y) is called first distance; Said origin coordinates (x; Y) with preset coordinate (800-x, the distance between 600-y) is a second distance, when said first distance during greater than second distance; Produce and carry out the first instruction S4, said first instruction is for amplifying current displayed image.Otherwise, when said first distance during, producing and carry out the second instruction S5 less than second distance, said second instruction is for dwindling current display image.Wherein, to the amplification of current display image or scale down by computes:

wherein; D1=sqrt ((x-400) * (x-400)+(y-300) (y-300)); D2=sqrt ((X-400) * (X-400)+(Y-300) (Y-300)), wherein origin coordinates be (x, y); In real time coordinate be (X, Y).

Being merely preferred embodiment of the present invention in sum, is not to be used for limiting practical range of the present invention.Be that all equivalences of doing according to the content of claim of the present invention change and modification, all should belong to technological category of the present invention.
