Computer generated multi-sensory simulation of an
artificial environment that is interactive and immersive.

5. What is Virtual Reality?
Virtual reality is..
a computer technology that replicates an
environment, real or imagined, and simulates a
user's physical presence and environment to
allow for user interaction. (Wikipedia)

113. 2. Add Gaze Reticle to Camera
• Gaze reticle shows the center of the camera view
• Gaze reticle prefabs
• GoogleVR à Prefabs à Cardboard
• Drag GvrReticlePointer under Main Camera
• In inspector click on ReticlePointer to set colour (red in this case)

114. 3. Add Physics Raycaster to Camera
• Used to send ray from camera to collide
with objects in the scene
• Select Main Camera

• Now when playing reticle changes shape over cube

116. Add Event Trigger Type
• We want something to happen when gaze at object
• Change object colour when person looking at it
• Add new event type to event trigger component
• Hit Add New Event Type button
• Add Pointer Enter and Point Exit events
• Need to add function scripts to events

117. 5. Create Gaze Input Script
• Create a new Script
• Cube à Add Component à New Script
• Name script GazeInput
• Edit Script – adding functions for changing object colour

118. GazeInput Script

119. 6. Connect Script Functions
• In event trigger drag Cube into object form
• In Pointer Enter add HighlightColour Function
• Gaze Input à HighlightColour()
• In Pointer Exit add ResetColour Function
• Gaze Input à ResetColour()

120. 7. Test Scene
• When gaze falls on Cube, Cube highlights white
• Resets to original colour when gaze moves off

• Move the Body object
• Add script to Main Camera
• Add component à New Script

127. VRLookWalk script

128. 4. Connect Character Controller to script
