This is the first part of my fourth lecture at the HITLab, Canterbury University in New Zealand. As a design practitioner I am frequently getting a question from other practitioners, why would they do user research in the first place. Once I manage to convince them why it makes sense, the follow up question typically regards the issue of choosing the right people for that research. In this presentation I am trying to highlight two different approaches to user research, which I will describe in more detail in the next presentation.

why doing user research in the rst place?
-users have dierent goals than designers -users do not care for design success -there is more than one user per solution -there is more than one solution per problem
traditional user research - formal - informative - answers - precision - understanding - raw data generative methods - informal - inspirational - questions - ambiguity - empathy - interpretation
user research: an example PhD project: Sebas1an Denef Promoters: David V. Keyson i Reinhard Oppermann
How do remen deal with dangerous situations in the midst of the action? How could their actions be supported through interactive technologies?

partcipants - 20 persons (50% M, 50% F) - recruited at the door of the providers shop - committed to buy a postpaid plan - signing an agreement to participate

why and when traditional user research?
- works great for the dened design space - helps to objectify discovered phenomena - supports task oriented design - resolves interaction problems - focuses in iterative measurement of progress - enables comparison
why and when generative methods?
- high complexity of the design issues (so called: wicked problems) - uncertainty what truly is the design challenge - need for exibility to approach the solution - building empathy
who should participate?
snowball sampling: when you want to nd users who have similar interests, jobs or lifestyle
extreme case sampling: when you want to nd users who are extreme representatives of certain behaviours (e.g. remen for a decision-taking study
homogenous sampling: when you want to nd users who are very much alike in a certain aspect
maximum variation sampling: when you want to nd users who are very dierent with respect to a certain aspect
convenience sampling: when you just want to nd users who are together for some reason (eg. a workshop) and agree to participate in the study
opportunistic sampling: when you just want to nd truly random users
