Interface Alternative of computers and the users
  • ?????????
  • ??????????????
  • ???
  • Hide the computer in the real world
  • Ubiquitous / Tangible computing
  • Put the user inside the computer
  • Virtual Reality
  • Relate Virtual World and Reality
  • Augmented Reality

Augmented Reality???
  • "Rather than turning inward to an artificial
    world,ubiquitous media encourages us to look
    outward.It expands our perception and interaction
    in the physical world. "
  • Bill Buxton 1998

03.Design example and principle
  • Tangible Interfaces
  • Tangible User Interfaces (TUI)
  • Transitional Interfaces
  • Attention
  • Spatial Information Displays
  • Spatial Conferencing
  • AR Conferencing

Spatial Information Displays ???
  • ?????
  • From 263x230 to 3156x230 pixels

  • Spatial audio, visual overlay

30
Spatial Conferencing
  • Wearable Conferencing Spaces
  • Mobile video conferencing
  • Full size images
  • Spatial audio/visual cues
  • Dozens of users

31
Spatial Conferencing???
  • Internet Telephony
  • Spatial Audio / Visuals
  • See-through HMD
  • Head Tracking
  • Wireless Internet
  • Wearable Computer
  • Static images

32
Spatial Conferencing???
  • Performance
  • Spatial audio improves understanding
  • Visual cues improve performance
  • Spatial visual cues not necessary
  • Subjective
  • Users prefer spatial audio
  • Users prefer some visual cues

33
AR Conferencing
34
AR Conferencing???
  • Initial Results
  • AR conferencing can increase presence
  • AR conferencing can increase communication
  • AR more difficult to use than audio/video
  • Subjective Comments
  • Felt remote user was real person
  • Difficult to see everything
  • Communication asymmetries
