Chapter seven in our book is about the act of data gathering. The chapter starts with identifying five key issues for anyone doing any kind of data gathering. These include setting goals, identifying and establishing a relationship with the participants. And then moves on to go into detail about different ways to gather data. The chapter i found most interesting was the one about data recording where different methods and tools to save the data you’re out on the field to gather is discussed and motivated. I’ve never before thought of this as such a vital part of the process and have in my few encounters with the subject always thought notes to be the best and most professional way. The chart at page 261 about choosing and combining techniques for data gather is one i’ll come back to in the future when our group is doing our field studies. It’s a great overview of different methods and negatives/positives.
Chapter eight continues to go deeper into similar subjects but focuses on how to analyze the data retreived after it has been gathered. The difference between quantitative and qualitative data is explained and one of the key takeaways for me is that a questionnaire or interview can be the source of both types of data. The chapter also introduces frameworks for analyzing the data, after first clarifying the importance of investigating if the framework fits.
Chapter ten focuses on establishing requirements and seems to me like one of the most vital tasks in HCI. Not matter if it's a new product or a redesign of an old one, there's always other work to study and learn from. Establishing requirements is a very broad subject and has many ways of being done. I think our group will have a much better understanding of this after we've been on our first field study as we will then have a better image of what people we are designing for.
