手势控制电脑---指标
手势控制电脑---指标<div id="cnblogs_post_body">The Year of 2010, one idea came to me:What about controlling the PC by gestures through the camera. In this way, every PC will have a "Touch screen" and it will save a lot of $, making it unnecessary to update screen into a Touch one. What's more, it will be a new interaction between Human and Computer, giving people new interactive experiences.
Sounds good isn't? So let's make it happen
------ The POINTER------
KEY POINTS：
1)Get coordinates：Mapping one point captured in the camerainto a proper position on the whole screen .Use the front camera with low resolution to catch gestures ,figure out the position of the tracking point ,then use Two-level Mapping Function (named by myself)to control the mouse's coordinates.1) 得到坐标：通过笔记本前置摄像头捕捉图像（分辨率较低，或通过插值函数而非真实物理分辨率），找出跟踪点，通过双层函数映射得到pc端鼠标位置（精确度5mm以内）。2)Get operations:Using color conbinations2) 通过颜色组合获得操作信息纪念下那些年，那些事，那些人
