Theme 5: Design research

When
designing media technologies, especially previously unexplored technologies
such as the hapics used in the paper “Turn Your Mobile Into the Ball:
Rendering Live Football Game Using Vibration” by Réhman,
S., Sun, J., Liu, L., & Li, H. (2008) I believe several steps are necessary
in order to come up with a good concept of the product or program. As a first
step you obviously need some product idea with theoretical support of why this product
might be a good idea to invest into. In the case of this paper the idea was
quite wild but backed up with the theoretic explaining that the vibrotactile sense
could harvest a lot of information.
A later step is to evaluate whether this product actually is useful or
not. In the case of the paper I believe it is useful to design a prototype to
test the basic mechanics of the product, in this case if the vibrotactile sense
could be used to follow the football game or if it was too complicated, distracting
etc. If the technology is quite unexplored I feel like a designing a prototype
followed up by user tests and evaluations might be a good idea. If the potential
of the technology already is explored this might be an unnecessary cost, for
example if one were to develop a faster computer or a screen with more colors.
The potentials with designing a prototype are that you can test you
hypothesis in a non-theoretical environment. You can use user evaluations to
gain knowledge about the topic and to prove theoretical concepts. A prototype
can be demonstrated to the public in order to gain attention and trust towards
your product.. There are different kinds of prototypes high and low fidelity
prototypes. A low fidelity prototype might be used to illustrate a concept,
while to evaluate something more carefully a high fidelity prototype might be
more useful. The downsides of developing a prototype are obviously that it is
costly and time consuming, and if the prototype turned out to be a failure, or
if dramatic changes had to be done to it the investment might have been for
nothing. If you use a low fidelity prototype the costs might decrease
dramatically and it might be worth making a prototype for the case of illustration.
You can gain knowledge about what works and what does not by developing a
prototype, but it might be big investment.

How does a collaborative
setting differ from a single user setting as regards methodology used and the
results obtained?
During a collaborative setting users can
communicate with each other. A problem with collaborative studies could be that
users interfere and affect each other, that could both be problematic ( if some
thought get held back or affected by for example group pressure) and positive
(participants might stimulate each other to get more well thought off answers.
We can example of a collaborative study in Sallnäs text "A haptic tool for group work about geometrical
concepts engaging blind and sighted pupils" we see example of a collaborative study where visually impaired and blindfolded
people work together with sighted people to perform tasks. The result might be
harder to analyze in collaborative environments as more variables have to be
taken into account for.
How can qualitative and
quantitative methods in the same study complement each other?
One thing I learned in the seminar last
week was that qualitative studies can be used to gain further insight on a previously
(relatively) unexplored topic. The qualitative study can be used to formulate
hypothesis and the hypothesis can be used to formulate good questions that
might be suitable in a quantitative study. The quantitative study is then used
to confirm and prove the hypothesis in order to form a complete study.
How can using both
subjective and objective methods give a better understanding of a phenomenon?
I believe that subjective and objective
methods can give different perspectives on a topic as well as complement each other.
Feelings, for example, is a subjective measure. To investigate how people feels
after being treated by something one might use both subjective and objective
methods to analyze. You cannot definitely say that “to fix a tooth hurts” as
the result of someone saying that is subjective, and not objective.
Nevertheless objective methods can be used to compile data gathered by
subjective methods. If a large enough percentage says that to fix a tooth hurts
a lot one might consider usage of narcotics to lessen the pain as a standard
procedure.
Thank you for your excellent comments on the articles.

Hello! Good work! you answer the question "How can qualitative and quantitative methods in the same study complement each other?" and you propose that first qualitative studies can be use to form an hypothesis followed by a quantitative to prove it. I very much agree with this line of work but do you think you can switch the order and still use both types of methods in an effective way?
SvaraRaderaIn order to perform a effective quantitative research i believe that in most cases it is vital that you have a well though of hypothesis to justify the research. I guess that you can use quantitative methods in order to formulate hypothesis as well. For example, if you want to make a research on the traffic in Stockholm you can start of my making a quantitative study of the flows of cars through various streets. You can then use qualitative methods to investigate what shapes these flows and how to interpret them.
