Virtual Reality

• This presentation will probably involve audience
  discussion, which will create action items. Use
  PowerPoint to keep track of these action items
  during your presentation
• In Slide Show, click on the right mouse button
• Select Meeting Minder
• Select the Action Items tab
• Type in action items as they come up
• Click OK to dismiss this box
• This will automatically create an Action Item
  slide at the end of your presentation with your
  points entered.

What is virtual reality?

• It is a new way to present 3-D images.
• Advanced versions of virtual reality permit a
  simulation that is indistinguishable from
  reality.
• Virtual reality combines hardware devices that
  interface with computers and software that
  generates with graphics within those computers.

8
Components of Virtual Reality

• A minimal virtual reality system includes
• a head-mounted video display
• tracking device
• glove

9
Components of Virtual Reality (cont.)

• An elaborate system of virtual reality includes
• Position trackers to monitor the location of body
  parts
• Treadmills to monitor foot movements with respect
  to the ground
• Muscle and brain electrical activity sensors that
  monitor performance of nervous system
• Full body data suit which covers the user with a
  second skin that simulates the sensation of touch
  to the wearer

10
Capabilities of Virtual Reality

• The components of a virtual reality system
  determine the degree of immersion, the scope and
  sense of navigation, and the level of interaction
  that the user experiences.
• In a full immersion system, the user interacts
  with a 3-D environment with no use of a computer
  keyboard or mouse.
• Non-immersive systems use the aid of keyboard and
  mouse

11
Tutorial Applications

• Virtual Physics Lab
• user can control gravity, friction, and time
  within a virtual environment to conduct
  experiments in motion

12
Student Project Development

• Elementary School Projects
• visit solar systems
• explore digestive tract

13
Student Project Development (cont.)

• High School Projects
• virtual hospital where students handle medical
  emergencies
• generating ancient cities

14
Access

• Schools may gain access to virtual reality
  systems
• cost effective
• the only way to perform certain activities
• provide protection for the safety of the student

15
Access (cont.)

• Virtual reality simulations of instructional
  applications in hostile environments would
  eliminate the danger to students or allow them to
  experience impossible situations.
• Learning about nuclear reactors
• exploring the ocean floor
• navigating the surface of Mars

16
Benefits of Virtual Reality

• Offers a better presentation format for certain
  subject matter
• Provides the student and the teacher control
• Makes information more concrete and easier to
  process
• Increases student involvement

17
Limitations of Virtual Reality

• Cost of a system
• Low quality of display
• Constraints of input and output devices
