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
technical field [0001] The present invention relates to a gesture method for a mouse, in particular to a gesture method for a mouse which enhances operation convenience. Background technique [0002] The traditional manipulation of the projector using the mouse is limited to clicking on the display object, and does not have the zoom control of the display object only by using the mouse, and the use has certain limitations. SUMMARY OF THE INVENTION [0003] The object of the present invention is to provide a gesture method for a mouse which can realize the zooming action of a display object through a mouse. [0004] In order to achieve the above object, the described gesture method for the mouse is characterized by, including, [0005] Step 1: Detecting whether a first gesture is performed, and the first gesture is to hold down the right mouse button; [0006] Step 2: Detecting whether a second gesture is performed; the second gesture is to hold down the left mouse button...
