Interaktion technology and design

1
Interaktion technology and design

• Technology and Design for interaction between
  Human, Information, and Things

2
Objectives with this course and book

• Introduction to systems and modeling (UML),
  design, mathematics, technology
• Interaction
• Human
• Intelligent thing
• Information och idea
• Analysis och synthesis of sound and image

3
Objectives, ctd

• A map in low resolution where details can be
  added as knowledge grows.
• A way of thinking in systems and models that is
  fundamental to an engineer.

Quality of life

• "Products or services that reduce the time and
  amount of tasks needed to be performed
• .. and increase our enjoyment, entertainment or
  reduce tension
• .. gives us information or challenges to improve
  our knowledge or our wellbeing"
• (Philips, enhanced)

Information processing) Memory(RAM, neurons, data)
Representation
Perception
9
H

• The interactor we know best (we think)
• Can we use this knowledge for better technology?
  Yes!
• Can we by building technology understand
  ourselves better? Yes (Signal processing, AI,
  MDI, Design)

H
T, I

I, Information, Idea

• Representation
• Analogue, digital
• Image, soound
• Text (Idea)
• Perception
• Data flow (Internet, e-mail, ) (data flows in och
  gives possibilities to improved reprsentations)
• !!! All perception have to be through T or H!!!
• Processning och minne
• Storge, search
• Signal processing

11
T, (Intelligent) thing

• Representation student question
• Light diode
• Sound
• Perception student question
• Button
• Mouse
• Camera
• Processing och memory student question
• CPU, RAM, ROM,
• Solving problems (Algoritm), decision
  (right/left), search (what face?), planning (what
  action?)
• Teaching? Creativity? Emotions?

H-H cooperation, competition
H-H The reference, something we know about (but
does not fully understand) Understand more by
studying technology, YES! If we understand more,
-gt better technology? Yes!

Reoccurring concepts

• Context
• Hierarchy
• Abstraction
• Aggregation
• Sequence
• Parallelism

17
Design

• Methodology, a way of thinking
• Not only smooth corners!!!
• User analysis (who is doing?)
• Task analysis (what is done?)
• Design (again!) (implementation)
• Not only aestheticsis is important!
• Apply it on computer hardware, software, cars,
  .....

18
Why study technology?

• New sensors
• New faster technology
• New software based tools
• New applications
