3. CHARACTERISTICS
WHAT CHARACTERISES A UBIQUITOUS COMPUTING
SYSTEM?
▸It should be embedded in, and be part of the environment
▸It allows the user to focus in the activity at hand, and not the system
▸Its purpose is to serve people
▸Entails interaction with the user
▸Much of its management is done autonomously and people is not aware of it
▸Involves large population of entities that deploy themselves flexibly and
responsibly in its work -such as hardware, software, infrastructure, even a
human
▸It pervades our lives, but remain controllable
4. QUALITIES
▸Fluid
its structure will vary in the short term and evolve in the long term
▸Purposive
Whether its purpose is expressed vaguely or formally; this is
what explains its actions
▸Autonomous
some of its actions are determined by its purpose and its interactive experience, rather than by invocation from a higher authority.
▸Reflective
a subsystem can report its experience to a higher system (perhaps to a human), to permit intervention or guidance.
▸Trustworthy
it will behave in a dependable manner and will not adversely affect information, other components of the system or people.
▸Sustainable
its components – hardware and software – are designed and built for long-life, efficient and effective maintenance and eventual
decomposition, while its lifetime impact on the environment (including humans and power sources) is appropriate but minimal
▸Efficient
any delays in its performance will be tolerable
▸Scalable
its subsystems will differ in size by many orders of magnitude, yet unmanageable
complexity will be avoided by applying the same principles of design and methods of analysis at each level.
6. EXPERIENCE
Understanding how the
user will experience
ubiquitous computing
involves close
relationships with a
range of other
disciplines and has
implications for both the
Engineering and
Theory perspectives.
7. EXPERIENCE
UBIQUITOUS COMPUTING IS SOMETIMES
CONTEXT-AWARE COMPUTING
▸ Understanding and Representing Human Activities and Context
Human Interaction in Ubiquitous Computing
Interaction with Environments
Interaction through Environments
Interaction Techniques
Designing Environments
Design Approaches
Design for Diverse and Evolving User Needs
Richer Usability Principles and Measures
New Forms of Evaluation
Social, Business and Ethical Issues

11. TASK I - DUE DATE JAN 22
NOT AN ESSAY
HOW WILL PEOPLE RELATE TO FUTURE UBIQUITOUS
COMPUTING ENVIRONMENTS, AND HOW CAN WE BEST
SUPPORT THEIR DESIGN? WHAT SENSE WILL PEOPLE
MAKE OF A WORLD WITH A MASSIVE NUMBER OF
UBIQUITOUS COMPUTING ELEMENTS? HOW SHOULD
THESE ELEMENTS PRESENT THEMSELVES TO
PEOPLE? HOW MIGHT WE EXPLOIT THE CAPABILITIES
SUGGESTED BY UBIQUITOUS COMPUTING
ENVIRONMENTS AND WHAT ARE THE IMPLICATIONS
FOR THE SOCIETY WE LIVE IN?
