The Virtual Health Clinic
The virtual health clinic allows students to diagnose and treat virtual patients with a variety of symptoms
When students have a question about a body part, organ, or system, they use a 3-D reference room with anatomical models and physiological systems
通过虚拟现实模拟，用户通过电脑可 以选择多种方式自由移动和熟练控制他所 处的环境，不像其它计算机游戏那样限制 用户的一系列选择设置。
Text understanding
Many VR headsets also include stereo speakers that allow virtual objects to “produce” sounds that appear to be coming from a specific direction.
VR Headset
Lets us see new views of virtual worlds as we turn our heads
Three-dimensional depth perception is created by “stereosopy,” where slightly different views of the same image appear to each eye.
Virtual Reality In Education
VR places students inside of a simulated environment that looks and feels like the real world.
Students interact in VR like they interact with the real world-objects can be picked up, turned around, examined from all angles.
它们表现能够通过导航指引被 实时的相互作用并更新的真实世界 或抽象环境。
Text understanding
With the use of special interfaces (means of communicating with the computer ,such as a joystick or keyboard),a user can “travel” through acomputer generated world and interact with objects in it. 通过特殊的接口（与计算机交流的 工具，像操纵杆，键盘之类的），用户 可以在计算机产生的世界里穿行并且和 对象相互影响。
Definition: A computer generated, ‘immersive’ (or wide field), multi-sensory information program which tracks a user in real time.
Text understanding
It is generally agreed that the essence of virtual reality lies with computer-based threedimensional environments. Often termed as “worlds”,they represent real-world or conceptual envirቤተ መጻሕፍቲ ባይዱnments that can be navigated through,interacted with and updated in real-time
VR Glove
Students see their hand in the virtual world, enabling them to pick up and manipulate objects Provide a new, natural way to interact and communicate with the computer
Virtual Reality In Education
Virtual reality (VR) can be described as a cutting-edge technology that allows students to step through the computer or television screen into a threedimensional, computer-simulated world to learn.
Head Tracking
A tracking mechanism registers any head motion by the student. When a student moves her head, the scene changes accordingly, just as in real life
许多虚拟现实头盔也提供了能 够让虚拟物体产生看起来来自一 个具体方位的声音的立体声耳机。
Text understanding
Much of their research has gone into creating environments that are an extension of CAD, allowing aechitects to “walk” through buildings they have just designed.Sense8 focuses on many of the more general uses of VR,using slightly less high-tech__but much much cheaper__hardware. 通过扩大计算机辅助设计，大量的研究已经 进入创造环境，让建筑师可以“自由穿行”他 们刚刚设计好的楼宇。第八感觉侧重于虚拟现 实的许多较一般用途，它们使用不那么高科技 但便宜的多的硬件。
Text understanding
.
During a VR simulation ,the user has complete freedom to move and manipuLate his environment in any way he cho oses__unlike many video games that lim the user to a set number of chioces.
Text understanding
They can creae a fairly good environment,however,they do Not allow the user complete freedom in that environment.
他们可以创建一个相当良好的环境， 但他们不能允许用户在这种环境中享 受完全的自由。
3-D Stereo Sound
Recognizing objects in the virtual world through 3-D sound greatly adds to the realism of the VR experience.
The volume of an airplane in a virtual world decreases as it moves away from you, just as in real life.
