Mark Weiser

• Chief TechnologistXerox PARC
• Began UbiquitousComputing Project in 1988

6
Weiser on Ubicomp

• What did you learn?
• READ THE PAPER!!!!!
• READ IT!

7
Ubiquitous computing

• Computation anyplace, anytime
• Invisible / seamless
• Physical / natural
• Replace HCI - NO! new focus
• Touches many areas of computer science

8
A new paradigm

• YES!!
• Others agree
• off the desktop, out of the box, pervasive,
  invisible, wearable, calm, anytime / anywhere /
  any place,

9
What is the humans perception?

• Pervasive yet unobtrusive
• The most profound technologies are those that
  disappear

10
Ubicomp is

• Related to
• Mobile computing
• Wearable computing
• Augmented reality
• In contrast with
• Virtual reality (augmented virtuality)

11
Ubicomp GaTech perspective

• Natural UIs
• Capture and Access
• Context-aware computing

12
Natural / implicit interfaces

• Integrate into human life
• Pen input
• Gesture
• Speech
• Perceptual UI
• Tangible UI

13
Context-aware interfaces

• Whats context?
• Who, what, where, when, why
• Context aggregation
• Context fusion
• Situation or activity detection / recognition
• What is a meeting?
• What does it mean to be cooking?

14
Capture access applications

• Compelling applications
• Design records
• Elephant box
• Everyday communication
• Annotations
• Fusion, indexing, summarization

15
Challenge of evaluation

• Bleeding edge technology
• Novelty
• Unanticipated uses
• Quantitative metrics

16
Social issues

• Privacy who has access to data?
• How do we make users aware of what technology is
  present?
• Differing perspectives and opinions
• Jane likes that the environment is aware she is
  present, but John doesnt

17
Lets focus

• Natural interfaces
• Speech UI
• Pen UI
• Gesture
• Perceptual UI
• Tangible UI

18
Natural interfaces

• What can make computing more ubiquitous?
• More of it
• More natural?
• Natural forms of human communication
• Different form factors
• Inch scale
• Foot scale
• Yard scale
• In more common devices / settings
