Human Computer Interaction (HCI)

What are User Interface Aspects? (4x)

  1. Physical
    1. e.g. pressing a button
  2. Perceptual (Erkennen)
    1. e-g- things we see
  3. Conceptual
    1. e.g. Mappings
  4. Logical
    1. e.g. input and output, or only one of them

Human Computer Interaction (HCI)

Was sind die Kernaspekte beim Design von interaktiven Systeme? (3x)

  • It is about designing the whole human-computer interaction
  • It is about designing the human-human interaction that is often enabled through devices
  • It is about designing whole environments

Human Computer Interaction (HCI)

What is a human-centered setting about? (4 aspects)

  • thinking about what people want to do
  • designing new ways to connect people with people
  • involving people in the design process
  • designing for diversity / inclusion

Human Computer Interaction (HCI)

What does PACT stand for?

P: People

A: Activities and 

C: Contexts

T: Technologies


  • PACT is a framework for designing interactive systems
  • It reminds designers of the important things to think about while designing


"People undertake activities, in contexts using technologies."

--> "A student (people) uses a phone (technology) to send a text message (activity) whilst sitting on a bus (context)."

Human Computer Interaction (HCI)

What is the relation between activities and technologies?

  • Activities establish requirements for technologies
  • Technologies offer opportunities to undertake activities in different ways


--> Specific designs of technologies can change the way, how people do activities and the other way around.

Human Computer Interaction (HCI)

PACT - People (3 Aspects)

Physical differences

  • Height
  • Weight
  • Different skills and capabilities
  • etc.


Psychological differences

  • differences in perception and attention
  • differences in memory - short term and long term
  • differentes in mental models of things


Usage differences

  • Experts versus newes
  • differences in designing for heterogeneous groups
  • etc.

Human Computer Interaction (HCI)

PACT - Characteristics of different Activities (4x)

  • Temporal aspects
    • Is timing or the frequency an important aspect of the activity?
      • e.g. designing so people can find their place again after an interruption.
  • Co-operation and complexity
    • Do we work with others or not?
  • Safety critical
    • What problems happen if something goes wrong?
  • Content
    • What information and media are we dealing with?

Human Computer Interaction (HCI)

PACT - Contexts

  • Activities always take place in some kind of context
    • Physical environment
    • Social context
    • Organizational context

Human Computer Interaction (HCI)

PACT - Technologies - Things to consider! (4x)

Hardware and software to consider

  • Input
    • How to enter data and commands into the system.
  • Output
    • Characteristics of displays/content
    • Feedback?!
  • Communication
    • Between person and technology
    • Bandwidth/Speed
  • Content
    • Functional systems vs. systems more focused on content

Human Computer Interaction (HCI)

Scenarios

  • Scenarios are stories about people undertaking activities using technologies in contexts.
  • Develop conceptual scenarios that cover the main activities that the technology has to support
    • E.g. 'Pete logs onto the computer'
  • Develop concrete versions of these for specific designs of the technology
    • E.g. ' Pete clicks on the "log on" icon.'

Human Computer Interaction (HCI)

PACT - Conclusion

  • Doing a PACT-Analysis is a good way of understanding a situation:
    • People demonstrate the wide range of knowledge, abilities and characteristics
    • Activities have different characteristics which affect how we design to support them.
    • Contexts of use affect the suitability of different things.
    • Technologies provide many opportunities for doing things differently.


--> Activities and contexts in which they happen set requirements for the technologies which in turn provide new opportunities.

Human Computer Interaction (HCI)

What is the difference between a formative and summative study?

Formative: Evaluation and optimization of a system with pre-defined criteria.

--> At the beginning to inform about context and to study possible options.


Summative: Evaluation after using/testing the system. 

--> To judge on the impact of a HCI design
