Why 3D? -It's obvious.
Isn't it?

• The WOW Effect
• Its Cool
• 3D Viewing is fun!
• 3D Viewing is the next step in display evolution
• 3D Viewing is important!

Learnability Aspects of 3D

• Better and faster comprehension
• If "a picture is worth a 1,000 words", a 3D model
  that you can rotate, zoom, and animate, is worth
  a 1,000 2D pictures in many situations
• Higher retention
• Tests show that learning effect through VR/3D is
  persistent

Learnability Aspects of 3D

• Immersive, Interactive Motivating
• 3D environments simulate a reality that is
  virtually close to the natural physical reality
  that we live in. They provide ways to experience
  and view information that are dynamic and
  interactive.

8852 VEC3D is an online e-learning environment.
It combines 3D rendering and real time voice
communication technologies to enhance immersion
and interaction between students

/elc/aquamoose/ AquaMOOSE A 3D interactive math
learning environment. The paper shows that 3D
graphical environments have significant potential
to support new forms of mathematical learning.

Learnability Aspects of 3D

• Improves spatial ability
• 3D graphics helps to improve the understanding of
  spatial relations between objects.
• Flexibility
• 3D environments provide ways to experience and
  view information that are dynamic and interactive

Few 3D Learning Environments

• Virtual Earth
• The Round Earth Project Collaborative VR for
  Conceptual Learning
• VEC3D
• A 3-D Virtual English Classroom for Second
  Language Learning
• AquaMOOSE
• A 3D Interactive Math Learning Environment
• WinTK
• Computer Graphics Animation in Programming
  Education
• C-VISions
• Socialized Learning through Interactive
  Simulations
• ChemPad
• For Teaching Organic Chemistry Students to
  Visualize Three-Dimensional Molecular Structures
• Virtual 3D Jigsaw
• For Studying the Effect of Exploring Spatial
  Relations with Implicit Guidance

Hurdles

• Ease of Use
• Using a 2D input device (the mouse) to control
  movement in a 3D scene presents usability
  challenge
• Conventional 2D monitor is very inefficient in
  displaying 3D information
• 3D interactive physical devices like 3D displays,
  head gears and 3D mouse are very expensive.
• Content creation
• Moving from 2D to 3D is as challenging as moving
  from maps to on-screen maps.
• Rendering Performance
• Being addressed by dedicated 3D graphics chips
• Data Exchange
• Convergence standards and 3D compression
  techniques

9
Cost/Efficiency Trade Off

• Virtual Earth Virtual Jigsaw require expensive
  VR equipment.
• AquaMOOSE Chempad work on conventional monitor
  and 2D mouse.
• High-end Graphics cards with dual monitor outputs
  are already quite mainstream items.
