(一)虚拟现实技术虚拟现实(Vinual Really,VR)技术是由多媒体与仿真技术相结合而产生的一种交互技术,它可以创造一种逼真的环境,使人有身临其境之感。要进入虚拟现实的环境,一般要戴上一个特殊的数字头盔和一副数据手套,感觉和操纵虚拟世界中的各种对象。目前 VR 技术还主要应用于少数高难度的军事、医疗模拟训练和一些研究部门,但它在教育领域有着不可估量的应用前景。例如美国休斯顿大学和美国
(1) Virtual Reality Technology Virtual Reality (VR) technology is an interactive technology generated by the combination of multimedia and simulation technologies. It can create a realistic environment and make people feel in the environment. To enter the virtual reality environment, a special digital helmet and a data glove are generally worn to feel and manipulate various objects in the virtual world. At present, VR technology is mainly applied to a few difficult military and medical simulation training and some research departments, but it has immeasurable application prospects in the field of education. For example, the University of Houston, USA and the United States
