Erik Duval

This document provides an introduction to human-computer interaction (CHI). It discusses some key principles of CHI, including that systems should be designed from the user's perspective, with a focus on usability. Examples of usability guidelines provided include that the system should be effective, efficient and satisfying for users to achieve their goals. The document also lists some important references in the field of CHI, such as formative conferences and publications.

There is a conflict of interest in the world of software development because the people who build it are also the people who design it. If carpenters designed houses, they would certainly be easier or more interesting to build, but not necessarily better to live in. The architect, besides being trained in the art of what works and what doesn't, is an advocate for the client, for the user. Alan Cooper. About Face, 1995 (http://www.cooper.com/)

Usability The effectiveness, efficiency, and satisfaction with which specified users achieve specified goals in particular environments This does not mean you have to create a “dry” design or something that is only good for novices – it all depends on your goals

hoe weet je dat een UI “goed” is?

You are not the user! (if you are the developer)
Four Myths Only experts create good designs Ä experts faster, simple and effective techniques anyone can apply We can fix the user interface at the end Ä good design is more than just user interface Ä having right features, building those features right Good design takes too long / costs too much Ä simple and effective techniques can reduce total development time & cost (finds problems early on) Good design is just cool graphics Ä graphics part of bigger picture of what to communicate & how
If the user does something “wrong”, it is the fault of the system designer!
“logical analysis is not a good way to predict people's behavior (nor are focus groups or surveys): observation is the key” “I caution that the time frame for adoption of new technologies is measured in decades, not the months everyone would prefer” Donald A. Norman
