Future Visions of Ubiquitous Computing

Ubiquitous Computing Challenge

  • The smarter unconscious
  • Who is the smarter chess player:
    • Beginner who analyzes everything
    • Grandmaster who moves intuitively
  • “Invisible” user interfaces
    • Embed in the environment
    • Dangling string network monitor
    • Many others possible, new area
    • Go to work on it!

Invisibility Needs Low Energy

  • Problem: communication with people is energy intensive
    • Displays, voice, all use lots of power
    • Joules/JND is getting worse!(Multimedia, 3D)
    • How to change the batteries on 100’s of ubicomp devices?
  • Challenge: low-energy UI
    • Example: slow display, like a newspaper
    • Example: tactile input

Scenario: One “6-pack of Computers”
“Honey, pick up a 6-pack of computers on your way home”

  • What will the $2 computer do?
    • Beam to nearby displays
    • Work together to create a custom work or play environment
    • Get specific content, such as news, novels, and homework assignments
    • Authorize special document access, such as entertainment and searching

1010 Channels

  • Technical issues
    • This breaks all known networks
      • Therefore it is a good challenge for you all
      • Key technologies: Mbone and RSVP
  • Social issues
    • Multimedia literacy is pointing a camera
      • Every garage band on the Net
      • Privacy a growing problem

New Complexity Analysis: Answer NetworkServer

  • No algorithm can guarantee efficiency(Pareto optimality at Nash equilibrium)
  • FIFO gives no guarantees
  • “Fair queuing” algorithms guarantee fairness, stability, and simplicity
  • Method: game-theory economic analysis.

Case study: Seoul Digital Media City
This project is a vision of modern hi-tech city quarter where are used developed technologies wherever possible. It is ubiquitous computing vision in practice. In the heart of this experimental city is Digital Media Street, where are localized the most interesting digital solutions and innovations. For instance, stripes on the roads are not painted, but animated and can change due to traffic conditions. Shops and cultural institutions communicate with your mobile or PDA to inform you about events and opportunities around you. Big screens will show you life in other parts of town or offer important news etc. However, it isn´t only amazing technological artifact, but also social experiment if people are able to live in such a developed (and all the time fast developing) place and if all technologies are useful for them.
