Embodiment
In order to make object of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Shown in Figure 1, a kind of method that makes the distributed display system of mouse-based operation, comprises the following steps:
Step S101, on host node, obtain mouse location information and mouse information (as clicked left button, slider roller etc.), when detecting that mouse slides outside the screen of described host node and during by system specialization, opening timing and also for example, obtain mouse translational speed one time every the schedule time (1/60 second).
Each the machine (can be referred to as again " demonstration node " or " node ") of distributed display system interconnects by network, if the screen resolution of each machine is Wi*Hi, each machine can form the viewing area of a W*H resolution by configuring rear screen.It should be noted that, in the present invention, after a mouse being connected on one of them demonstration node, this shows that node had been both host node.In addition, the present invention need to install a program in each demonstration node deploy, and each program need to be carried out corresponding configuration according to viewing area composition---and each shows the position (pxi, pyi) of node with respect to viewing area, screen resolution (Wi, Hi) and IP port etc.
As shown in Figure 2, in each machine deploy program of the present invention, and at the upper mouse that connects of a machine (machine 0).The display screen (resolution is W × H, and what W was resolution is wide, and H is for high) of each machine is arranged in the capable n row of m, forms large " a demonstration wall ", and m*W × n*H that the resolution of this demonstration wall is, is decided to be the lower left corner (0,0).Mouse initialization bit is set to (x0, y0).
Step S102, the current coordinate of mouse translational speed computing mouse that basis gets on described host node.
As a good embodiment, the current coordinate of mouse (x, y) can be that a upper moment coordinate (xi, yi) adds the number of pixels that a moment moves, concrete, the process of the current coordinate of mouse translational speed computing mouse that above-mentioned basis gets specifically can comprise as follows:
