Personal ubiquitous systems
Personal Ubiquitous Systems

  • Ubicomp vs. “Shared” devices

Personal ubiquitous systems1
Personal Ubiquitous Systems

  • Embedded Design Approach

    • Integrate personalization with an already existing interface/device

  • Portable Design Approach

    • Personal interface for mobile devices

  • Which one?

    • Comparative evaluation time!

  • Portable Design Approach

    • Personal interface for mobile devices

  • Is that all?

Comparative evaluation
Comparative Evaluation

  • Design with alternative

  • Vary deployment situations

  • Compare and contrast

Personal interaction points pips
Personal Interaction Points (PIPs)

  • System for shared pervasive devices

  • “smart” access

  • Information cloud

  • Podium PC

  • Brainstorming plasma

  • MFD

Personalization design
Personalization Design

  • Idetifying users

  • Learning and remembering

  • Creating personalized UI

Embedded vs portable
Embedded vs. Portable

  • Direct access w/ peripherals


  • “Remote control”


  • A success!

  • PIPcidents

    • Usability decreases with portability

    • Lazy people prefer to be lazy

    • Availability increases with portability

    • May be untrustworthy

    • Portable = private


  • Usability and availabilty

    • Varied based on design

  • Utility and privacy

    • Varied based on design and situation

Back to the future comparative prototyping

Everyday encounters with context aware computing in a campus environment
Everyday Encounters with Context-Aware Computing in a Campus Environment

Ubicomp motivation
Ubicomp motivation Environment

  • Expand computers beyond desktop confines

  • But it’s dangerous out there!

  • Expand ubicomp beyond academic confines

  • Time for the real world, ubi!

Institutional analysis

‘meso-level’ approach



Ethnomethodology –----------Marxist analysis

Taking it to the real world
Taking it to the real world! Environment

  • “Given that many ubiquitous computing technologies are developed, deployed, and evaluated in university settings, our particular institutional concern is with student life on a university campus and how these institutional arrangements manifest themselves for students day-to-day.”

Taking it to the real world1
Taking it to the real world! Environment

  • “There are many reasons to expect that campus environments are ideal for the development, deployment, and testing of ubiquitous computing technologies. Clearly, many technologies are developed in university research, and campus environments are therefore convenient.”

Ubicomp in practice
