1. Levels of Design
Designing Human Activities

University of Siena, Italy
2. Different human activities / Different levels of design
Design for Human Activities
o I know what I want and I can also specify most of the
conditions of satisfaction of my actions and target results
o I’m interested in doing it, I cannot tell you precisely what
do I expect in term of actions or results but as things
evolve I will tell you,
o I’m curious about it, but I do not know what this imply
neither what can I expect

reactive
pro-active
emergent

solve problems of use for
a well established
human activity/task
already mediated by
existing and fully

20. Mock-up development and testing
Design Concepts:mock-up construction
Mock-up testing
To assess the validity of the concepts
To explore the potentiality of the basic and elaborated setting of POGO Tools
To gather significant data for the further experiments on interaction design
To detail User Requirements with respects to the “Acquisition”, “Manipulation” and “Publishing” Phase
Suggestions for high fidelity prototyping

26. EL methods
Activity: future scenarios
Evaluation: simulations with
stakeholders
Design: theoretical reflection,
future workshops,

27. Conclusion
o Every design process has its own story
o Egg Model provide an heuristic guide
for navigating between existing HCI
methods
o It help students to properly understand
the role of the three main design
phases for designing for human activities

28. Why is RL Important?
It can determine who
becomes president of the USA!

29. Problems
• The instructions are misleading
– Use of the phrase “vote for group” is misleading
• Should say “vote for one”
– Instructions only on lefthand side
• Implies righthand side is different
• The interleaving of holes is misleading
– Only the president page has this layout
– Other offices are one per page (with appropriate instructions)
• The sample ballot looks different
– No holes – the source of the problem
– Did not lead to complaints
