Augmented Reality Definition
  Defining Characteristics [Azuma 97]
  Combines Real and Virtual Images
-  Both can be seen at the same time

Augmented Reality Examples

AR vs VR
  Virtual Reality: Replaces Reality
  Scene Generation: requires realistic images
  Display Device: fully immersive, wide FOV
  Tracking and Sensing: low accuracy is okay
  Augmented Reality: Enhances Reality
  Scene Generation: minimal rendering okay
  Display Device: non-immersive, small FOV
  Tracking and Sensing: high accuracy needed

Augmented Virtuality
  VR with windows into the real world

Metaverse
  Neal Stephenson’s “SnowCrash”
  The Metaverse is the convergence of:
  1) virtually enhanced physical reality
  2) physically persistent virtual space
  Metaverse Roadmap
  http://metaverseroadmap.org/

Metaverse Dimensions
• Augmentation technologies that layer information onto
our perception of the physical environment.
• Simulation refers to technologies that model reality
• Intimate technologies are focused inwardly, on the
identity and actions of the individual or object;
• External technologies are focused outwardly, towards
the world at large;

Metaverse Components
  Four Key Components
  Virtual Worlds
  Augmented Reality
  Mirror Worlds
  Lifelogging

Mirror Worlds
  Mirror worlds are informationally-enhanced
virtual models of the physical world.
  Google Earth, MS Street View, Google Maps

LifeLogging
  Technologies record and report the intimate
states and life histories of objects and users
  Nokia LifeBlog, Nike+, FitBits

  Steve Mann - LifeLogging

Gordon Bell: LifeLogging
1 TB to store 65 years of data

Narrative Clip
  Wearable camera
  Automatic picture capture - 2 pics/minute
