EXERCISE 20.8 [extra - not in book]
Dean Whitney theme parks are planning
a new family exhibit "Lost in Space". Using
virtual reality techniques, family groups will be
able to fly in a spacecraft and then land on a simulated
(a) Suggest suitable VR technology to
give the family a shared experience.
(b) Describe how these can be used to foster a sense
of immersion in the virtual environment.
answer available for tutors only
Room as simulated cockpit, family can sit on real
chairs etc., with realistic instruments and seeing
each other. Views of outer space projected onto 'windows'
- possibly use portholes, smaller cheaper displays!
For landing on surface, could dress each member of
family up in full body VR suit (or just head goggles
with data gloves) and allow them to move and interact
in 3D simulated environment with each member of family
having an avatar.
Realistic controls. Force feedback from controls (rattle
at take off and landing). Sound effects. Large pistons
to move cockpit around. Control and feedback - e.g.
press thruster controls and spaceship moves. When
in body suits: air blows in windy areas, ability to
pick up objects and move around in the virtual space,
possibly even alien smells (all bad!).
