基于手势交互的三维电子沙盘系统设计与实现

Design and Implementation of 3D Electronic Sand Table System Based on Gesture Interaction

基于手势的人机交互方式可大大提高人对计算机系统的控制能力,实现人机自然融合。首先,简要分析了Leap Motion设备进行手势识别的特点,详细阐述了利用Unity3D构建三维电子沙盘的方法和流程,在此基础上提出了基于手势交互的三维电子沙盘系统集成技术框架;然后,设计了基于Leap Motion的手势识别方案和控制脚本的基本流程,最后搭建系统实例并进行测试。测试结果表明,通过Leap Motion可实现人手对沙盘系统的预定操作,为这种新型手势识别技术的应用提供了一定借鉴。

The human?computer interaction based on gestures will improve people?s ability to control the computer system, and achieve human?computer fusion. The characteristics of using Leap Motion to recognize gesture is analyzed. The method and process of using Unity3D to construct 3D electronic sand table is discussed. System integration technology of 3D electron?ic sand table based on gestures interaction is put forward. Gesture recognition scheme based on leap motion and main process of script is designed. At last, an example system is build and tested. Test results show that using Leap Motion can realize hand operation to electronic sand table, and provide some reference for the application of gesture recognizing technology.
