为了实现在Virtools环境下利用手势对虚拟物体进行交互操作，设计开发了一个针对Kinect设备的插件。该插件基于Kinect的程序开发接口和Virtools的软件开发工具包，以Visual C＋＋2010．Net为程序开发工具设计实现。首先根据Virtools的软件架构和模块开发技术，设计插件的管理器和行为模组，它们提供手势信息与手点位置；然后设计相应的扩展行为模组，利用手势选中物体零部件，零部件跟随手的运动做平移或缩放；最后通过实例验证了该插件的手势识别和手部跟踪功能的有效性，扩展了Virtools软件的应用领域。%To realize interactive manipulation upon virtual objects with gestures in Virtools environment , a plug-in is specially designed and developed for Kinect devices .The plug-in takes advantage of Kinect API and Virtools SDK and is implemented with C ++2010.Net as its developing tool .Firstly according to Virtools software structure and module development techniques , a plug-in manager and a behavior pat-tern group are designed , which provide gesture information and hand point positions .Next a corresponding extended behavior module group is designed, by which the object parts can be picked up by gestures and moved around or scaled with hand movements .Finally a practical in-stance validates the effectiveness of gesture recognition and hand tracking function , so that the Virtools application realm is expanded .
