摘要
为提高人机交互的效率和自然性，近年来多媒体、多通道交互和虚拟现实技术迅速兴起，而三维空间交互技术在其中占有重要地位，并广泛应用于ＣＡＤ／ＣＡＭ和科学计算可视化等领域．本文指出三维空间交互的直接操纵本质，介绍操纵三维对象所需的六自由度三维空间控制器的原理和应用．
Recently multimedia,multimodal interaction and virtual reality technology are increasing quickly to improve the efficency and nature of human computer interaction,in which 3D space interaction technology plays an important role and has being applied in some fields such as CAD/CAM and scientific visualization.In the paper the authors point out the essense of direct manipulation in 3D space interaction technology,and discuss the principle and application of 3D space controller with six degrees of freedom which is the necessity for manipulating 3D objects.
