自然用户界面NUI的清晰、简洁、智能化的方式让用户体验更加直观,更为人性化。基于自然用户界面的应用设备层出不穷,手势识别这种操作技术占据了重要的位置。随着虚拟现实技术快速发展,人们的办公方式也发生了很大的变化。在幻灯片演示方面,传统的方式显得呆板,不能让人们自由使用动作。因此,文中提出一种使用手势来代替鼠标输入的方法,使用Leap Motion 控制器。经过试验,计算机的反应速度快,并能准确地辨别出有效手势,能够对幻灯片进行操作。

The natural user interface (NUI)is widely used because of clearance, conciseness,and intelligence. NUI-based applications have grown rapidly, particularly the use of gestures, which have occupied a pivotal place in the technology. With the rapid development of virtual reality technology, people’s workplaces have great changes. The traditional way to use mouse to control PowerPoint is bored. It can’t use people’s body freely. Therefore, considering this circumstance, one solution was presented by employing NUI technology for controlling PowerPoint using gestures. After a simulation experiment, the results show that computer can accurately identify a valid gesture, and PowerPoint can be controlled by gesture.
