In the
first group seminar we discussed topics from chapters 7, 8 and 10. These
chapters are about the beginning stages of a design
process.
The 7th
chapter is about data gathering and goes through processes of interviews and
questionnaires e.g. cultural probes, all methods
of survey research and observation, a method of behavioural research . The think-aloud technique is good because it will allow the designer to get a look at the user's experience of a product.We separate between quantitative and qualitative
data. Quantitative data is in the form of
numbers and qualitative data usually includes more abstract data like descriptions, quotes,
vignettes of
activity, photos
and drawings. Sending out cultural probes are also a way of gathering data.
Chapter 8
is about data analysis and how to interpret the data gathered in chapter 7. Closed questions are usually
analysed quantitatively, open questions
qualitatively. Quantitative analysis
usually includes systematising the data in matrices or looking for averages. The book defines three types of qualitative analysis of empirical data: identifying recurring patterns and themes,
categorizing data and analysing critical
incidents.
This
chapter also presents theoretical frameworks
as a way to structure data. The method
includes the grounded theory, that uses the data gathered to generate the actual theory. The research is developed with
the data gathered, so the theory alternates between data collecting and analysis.
The theory identifies categories of data
and methods to relate these to each other.
A more psychological approach is the activity theory. These methods seem quite extensive and difficult to fully
understand.
Conclusively,
the chapter has a section about summarising
and presenting the data.
The last
chapter for this seminar is about establishing
requirements. In the requirements activity, we want to achieve two
things. The first is to understand as much as possible about the users, their activities, the contexts of those activities and their goals so that the system that is being
developed can aid the user to achieve his goals. Tools to get a better understanding of this
is creating personas and scenarios based on the chosen focus groups. Personas are fictive, typically
short descriptions of a person's life situation, goals and behaviour relevant
to the design inquiry. A scenario is a
narrative that explores the future use of a product from a user's point of
view. After the first field study, I think the group will have more
information to create personas and scenarios. I have used these in earlier
design projects, and they are really helpful!
