Virtual Reality Interface for Web-Based Remote
Experimentation
Objectives

• Perform a 3D-based experiment any time anywhere
  through the Internet

• Perform an actual experiment physically over
  Internet

• Share some expensive instruments

• Have a more natural hands-on experience of using
  these instruments

Virtual Reality Interface for Web-Based Remote
Experimentation
Features

• Use a browser with Java and Java 3D runtime, such
  as Microsoft Internet Explorer or Netscape
  Communicator

• Adopt some relevant real instruments in the
  laboratory instead of simulating the experimental
  result on the client computer

• Give a more realistic feel of the instrument in
  manipulating 3D control buttons and knobs of the
  instrument
