Pervasive Computing Applications for Science
Education Recent Research Advances
  • Dr Theodoros N Arvanitis
  • Senior Lecturer, Head of Biomedical Informatics,
    Signals Systems Research Laboratory, Department
    of Electronic, Electrical Computer Engineering
  • Director, Centre for Learning, Innovation

Pervasive Computing in EducationRealising Our
Imagination
  • "Leave the beaten track occasionally and dive
    into the woods. Every time you do so, you will be
    certain to find something that you have never
    seen before. Follow it up, explore all around it,
    and before you know it, you will have something
    worth thinking about to occupy your mind. All
    really big discoveries are the result of thought."

Alexander Graham Bell "electrical speech
machine" of 1876

What is Pervasive Computing?
  • Mainframe many people share one computer
  • Personal Computer one person with one computer
  • Pervasive Ubiquitous computing many computers
    serve each person
  • Pervasive Ubiquitous Computing can be thought
    of as the idea of invisible computers everywhere.
  • computers are embedded in the environment,
  • each computer performs its tasks without
    requiring human awareness or a large amount of
    human intervention.

Major Trends in Computing
5
Philosophy and Goals of Pervasive Ubiquitous
Computing
  • Computing paradigm in contrast to the desktop
    model
  • Integrate computers into our everyday activities
  • Computer embodiments in infrastructure have
    varying size and shapes
  • Early Steps Construct, deploy, and evaluate
    tabs, pads, and boards

6
The Early Steps of Pervasive Ubiquitous
Computing
  • The initial incarnation of ubiquitous computing
    was in the form of "tabs", "pads", and "boards"
    built at Xerox PARC, 1988-1994.
  • Mobile Computing Research
  • explore the capabilities and impact of mobile
    computers in an office setting
  • Palm-sized mobile computers that can communicate
    wirelessly through infrared tranceivers to
    workstation-based applications.

7
Types of Ubiquitous Computing Devices
  • Tabs
  • small, handheld devices, like Post-it notes, or
    the spine of a book
  • must carefully balance display size, bandwidth,
    processing, memory, power consumption
  • Pads
  • paper-sized tablets
  • a number are commercially available, but they are
    not well-suited for the generalized requirements
    of a research environment, which includes high
    customizability
  • PARC's MPad used FPGAs, so they can even
    reprogram their hardware!
  • Boards
  • intelligent whiteboards, allowing for
    collaborations, storage, etc.
  • Wearables

8
Applications of Pervasive Ubiquitous Computing
  • Locating people
  • Collaboration tools
  • Environment control
  • Virtual communities
  • Indirect Management

9
Wearable Computing in Science Education The
Challenge
  • Bridging the gap between pedagogy and front-end
    technology
  • Introducing innovation in learning and
    computational tools
  • The Lab of Tomorrow project is a European project
    primarily concerned with capturing sensor data
    from the local environment, for transmission to
    some control computer or computers. This is then
    be used for analysis during science school
    classes (e.g. high-school physics)
  • Introducing the concept of wearable computational
    and on-body sensing devices
  • Combining the use of toys for activity-based
    learning
  • An elaborate system of distributed computation,
    embedded-sensing devices, positioning
    calculation, and data analysis.

Lab of Tomorrow The Vision
  • To contribute towards the connection of science
    with everyday life activities

Wearable Computing Our Perspective
  • A new form of an embedded-computing
  • Computing paradigm in contrast to the desktop
    model
  • Integrating computers into our everyday
    activities
  • Wearable (a definition)
  • Portable while operational
  • On-body, embedded in clothes, hands-free
  • Sensing the environment
  • Supporting activity in a ubiquitous manner
  • Always-on (depending on energy capacity) ?

Technological Societies blessing or burden ?
  • Computer Systems are getting more complex over
    time
  • Distributed systems present an inherent
    complexity in architectural design and in the way
    information is structured
  • Overload of information vast, dynamic or even
    unstructured information
  • Vagueness of human knowledge
  • More everyday tasks involve computers
  • More users without the necessary skills

16
Calm Technology Pervasive computing
  • To cope with the vagueness of human knowledge,
    the complexity of systems and the needs created
    by the new information pool it is required that
    we leave computers in a proximal periphery and
    focus on calm technology
  • In other words, build technology that gets our
    attention when we need to use it, but that
    relegates itself to the background, and stays
    aside, actively waiting to assist us.

Thank You
  • The world we have created today has problems
    which cannot be solved by thinking the way we
    thought when we created them
