To evaluate a design in form of a prototype is a very
common and interesting research. The study become more realistic and the
investigation give more data in form of quantitative and qualitative materials.
At the Wednesdays lecture with Eva-Lotta, she talked about how doctors at
Karolinska Institutet communicate with each other differently depending whether
they had tools to communicate with or not, to show each other what they mean at
the big screen. I haven't think about how human’s behaviour and haptic can
differ in different situations depending of the limitations of communication.
Just like a small little laser pointer can change the dialog between the
doctors to plan a surgery. The understanding increased in the distance between
doctors at the place and the others away.
She also discussed how a qualitative study could be
complemented with a quantitative research in form of measuring clicks, times
and other methods to gain knowledge and learning’s from the qualitative study.
I think it's interesting and important to know how the quantitative and
qualitative studies can support each other. I always thought that this method
has been separated.
I wrote my bachelor thesis around Usability, the topic
Haibo Li talked about today. Usability is about to evaluate a system/product in
order to reach effectiveness, efficiency and satisfaction. He gave an example
of the effectiveness, where some rats eat coffee to improve their productivity.
The measure shows the how the productivity increased with the amount of
ingestion that investigates weather the coffee have an impact. I think this is
an important area to analyse in relation to an evaluation of a design.
Hey!
SvaraRaderaVery nice reflection and I agree that usability is very important. I had some courses about it and I think that it's something that every company has to consider. Moreover, I thought too that qualitative and quantitative cannot be done together in a research! ;)
Interesting, then you’ll understand what I mean with the reliability of the method. It become more realistic and the participators feel more involved and the interaction become more real. I think we both have learn something new about quantitative and qualitative researchers and its good to have in mind for further work.
RaderaHi,
SvaraRaderaI agree with you that the qualitative study could be complemented with the quantitative study. I think each of them have their own strength and weakness, and when we use both methods, hopefully we can make a more complete result of our research. For example, Eva-lotta's mention that we can conduct an interview or video recording to gather initial data to get opinion and activity during an experiment. This data can process further, for example, we can transcribe the voice into a text. Therefore, we can extract some of the data and process further with the quantitative study. By using both methods we can gather information based on subjective (opinion) and objective (statistic) to enrich the research result.
Yes, it’s smart to analyse the data from two directions to gain a broader perspective of the situation, the respondent’s opinions and the statistic result. Both quantitative and qualitative studies can include the subjective and objective method. For the qualitative it can be the direct thoughts and measurements of movement in an interview video. The quantitative can collect data in a statistic way and the subjective thoughts through open fields in a survey.
RaderaThanks for your good comment!
Hi Kristina! I agree with you, usability is a very important factor to consider when developing a product or a service. I think it is becoming more and more central in the developing process and that people are becoming more aware of the importance of usability.
SvaraRaderaYes, the tool to understand the user is nowadays very important and attractive by many companies surrounding the interaction industry. In my opinion, the satisfaction and attraction by the users user is important and it increases in the ICT industry. The high values to be the most useful application or device become broader. To carry on the knowledge of usability is today like gold.
RaderaHi Kristina,
SvaraRaderaGood thoughts! I think it sounds interesting to do a bachelor within the area usability. I think usability is a very important area today because of the structure in our society and the importance for everything and everyone to be efficiency and effective. Why do you think the usability area is important to analyse in relation to evaluation a research design?
