openni+nite体感鼠标模拟

        最近在学openni，所以做一个体感鼠标练练。主要功能，就是一只手负责定位鼠标在屏幕的位置，一只手进行点击或者其他的操作，并且可以通过一些特定方式进行左右手切换等操作。

第一步就是设置鼠标以及屏幕等的参数，为了方便，我们使用ini文档进行配置，主要包含：屏幕尺寸，帧数，左右击键等配置。

[Setting]
ScreenRes_X=1440
ScreenRex_Y=900
nFPS=30
LeftClickDownSpeed=600
LeftClickUpSpeed=600
RightClickSpeed=600
PushSpeed=1000
MouseMove_Xsize=600
MouseMove_Ysize=400
angle=30
Touch=250
off_ZSpeed=150
on_ZSpeed=130
nSteadyDelayTime_MouseClick=1000
fSteadyMaxVelocity_MouseClick=0.01
fNotSteadyMinVelocity_MouseClick=1.000

配置好之后，利用下面函数进行配置文件里的数据读取操作。

void GetSettingValue()
{
ScreenRes_X=GetPrivateProfileInt(L"settings",L"ScreenRes_X",1440,L".\settings.ini");
ScreenRes_Y=GetPrivateProfileInt(L"settings",L"ScreenRes_Y",900,L".\settings.ini");
MouseMove_Xsize=GetPrivateProfileInt(L"settings",L"MouseMove_Xsize",600,L".\settings.ini");
MouseMove_Ysize=GetPrivateProfileInt(L"settings",L"MouseMove_Ysize",400,L".\settings.ini");

on_ZSpeed=GetPrivateProfileInt(L"settings",L"on_ZSpeed",20,L".\settings.ini");
}
