Design for Human Activities
o I know what I want and I can also specify most of theconditions of satisfaction of my actions and target results
o I’m interested in doing it, I cannot tell you precisely whatdo I expect in term of actions or results but as thingsevolve I will tell you,
o I’m curious about it, but I do not know what this implyneither what can I expect

Conclusion
o Every design process has its own storyo Egg Model provide an heuristic guide
for navigating between existing HCImethods
o It help students to properly understandthe role of the three main designphases for designing for human activities

Why is RL Important?
It can determine whobecomes president of the USA!

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

Original contribution with respect toother interaction design processmodels currently adopted. Indeedmost of the available processmodels derive from the earlywork of the Xerox Star researchgroup that proposed a user-centred view for the design ofinnovative products (Bewley et al.1983, Smith et al 1982, Gould andLewis, 1983).
• From that pioneering work, manyother formulations of the originalidea were proposed with the aimto consolidate design practiceswith a clear user orientation.However, all these models (Beyerand Holtzblatt, 1998, Lewis andRieman, 1993, Preece at al. 1994,Shneiderman, 1992) do not takeinto account the differentmeanings that the “design for theusers” approach assumes indifferent contexts.
