Q

Applications of ICT:
Virtual Reality

What is this?

  • Eye goggles - these produce the 3D images that make up the artificial world, slightly different views are projected into each eye to make it look 3D
  • Special gloves - they detect your hand and finger movements which are input into a computer to be processed
  • Headphones - these control what users hear, and can change the location and volume of sound to project where they are coming from
  • Powerful computer - a very powerful computer is needed to create the virtual environment and to process/output the necessary data

17
Q

Applications of ICT:
Virtual Reality

What is this?

  1. Improved medical surgeons - they can be trained using virtual patients, allowing lots of practice without real risk
  2. Larger and stronger buildings - allows architects to walk around their design and check for potential errors, and also allowing virtual buildings to be tested against natural disasters
  3. Training in dangerous situations - can be used when it is impossible to practice in the real thing
  4. More realistic education - can allow students to learn in a much more interactive way, allowing them to retain more knowledge
A

four examples of useful applications of virtual reality.

20
Q

Applications of ICT:
Expert Systems

Describe the three components of an expert system.

A
  1. The user interface - this allows the user to communicate with the expert system
  2. A knowledge base - this is the information about the area of expertise, it contains facts and rules to be able to make decisions like a human
  3. Interface engine - uses the knowledge base to make decisions and come to a conclusion using the user provided information
