中文摘要：
计算机软硬件技术的发展使非接触的人机交互方式成为可能,其中基于计算机视觉的手势识别技术就是一种正在被广泛应用的交互方式,它可以实现对计算机的连续、快速及直观的输入。虚拟地理环境（VGE）作为新一代地理学语言,以最接近人类自然的交流方式来表达地理现象和过程,因此对人机交互方式有更高的要求。本文试图将目前比较前沿的人机交互技术——基于计算机视觉的手势识别技术引入到虚拟地理环境中,增强虚拟地理环境交互方式的友好性、直观性。
英文摘要：
With the advances of computer software and hardware technologies,non-contact ways of human computer interaction become possible,among which computer vision-based gesture recognition is being widely used that can realize human input into computer continuously,fast,and intuitively.On the other hand,as a new geography language,virtual geographical environment,in short VGE,aims at representing spatial phenomena and processes in a natural and straightforward way,and thus it requires more flexible measures in human computer interaction.In view of this,the paper introduces currently cutting-edge human computer interaction technology,computer vision-based gesture recognition,and brings it into virtual geographical environment to enhance friendliness and intuition of interaction ways of VGE.
