Leap提供了SDK。但是整合有很多的问题，写博客记录一下；
写一个类：SampleListener.cpp以及头文件SampleListener.h。
这里主要碰到的问题是找不到以及冲突问题；
这里最关键的是用的不能写using namespace Lead。必须写Lead::这种形式。
代码如下：
#include <iostream> #include <cstring> #include "Leap.h" //using namespace Leap; class SampleListener : public Leap::Listener { public: int civiv;//手机识别的标志 void onInit(const Leap:: Controller&); void onConnect(const Leap::Controller&); void onDisconnect(const Leap:: Controller&); void onExit(const Leap:: Controller&); void onFrame(const Leap:: Controller&); void onFocusGained(const Leap:: Controller&); void onFocusLost(const Leap::Controller&); void onDeviceChange(const Leap:: Controller&); void onServiceConnect(const Leap:: Controller&); void onServiceDisconnect(const Leap:: Controller&); void onStart(); private: };
SampleListener.cpp:
#include "stdafx.h" #include "SampleListener.h" using namespace Leap; const std::string fingerNames[] = {"Thumb", "Index", "Middle", "Ring", "Pinky"}; const std::string boneNames[] = {"Metacarpal", "Proximal", "Middle", "Distal"}; const std::string stateNames[] = {"STATE_INVALID", "STATE_START", "STATE_UPDATE", "STATE_END"}; void SampleListener::onInit(const Leap::Controller& controller) { std::cout << "Initialized" << std::endl; } void SampleListener::onConnect(const Leap:: Controller& controller) { std::cout << "Connected" << std::endl; controller.enableGesture(Gesture::TYPE_CIRCLE); controller.enableGesture(Gesture::TYPE_KEY_TAP); controller.enableGesture(Gesture::TYPE_SCREEN_TAP); controller.enableGesture(Gesture::TYPE_SWIPE); } void SampleListener::onDisconnect(const Leap:: Controller& controller) { // Note: not dispatched when running in a debugger. std::cout << "Disconnected" << std::endl; } void SampleListener::onExit(const Leap::Controller& controller) { std::cout << "Exited" << std::endl; } void SampleListener::onFrame(const Leap:: Controller& controller) { // Get the most recent frame and report some basic information const Frame frame = controller.frame(); std::cout << "Frame id: " << frame.id() << ", timestamp: " << frame.timestamp() << ", hands: " << frame.hands().count() << ", extended fingers: " << frame.fingers().extended().count() << ", tools: " << frame.tools().count() << ", gestures: " << frame.gestures().count() << std::endl; Leap::HandList hands = frame.hands(); for ( Leap::HandList::const_iterator hl = hands.begin(); hl != hands.end(); ++hl) { // Get the first hand const Leap:: Hand hand = *hl; std::string handType = hand.isLeft() ?

嵌入师兄的MFC写的程序中:
注意因为与师兄写的变量冲突，所以这里不能写using namespace Lead。必须写Lead::这种形式。
EyeTrackView.h:
#include "TshirtCode.h" #include "TshirtDraw.h" #include "GeneticAlgorithm.cpp" #include "CvvImage.h" #include <deque> #include "shockwaveflash1.h" #include "pupilDetector.h" #include "Device.h" #include "communication.h" #include "DeviceEyeDataAnalyze.h" #include "HardWord.h" #include "SampleListener.h"
EyeTrackView.cpp照常引入EyeTrackView.h。
