1. How can media
technologies be evaluated?
One way to evaluate is to do usability tests as in the assigned article Turn Your mobile Into the Ball. Of course the evaluation should be optimized depending on the platform you’re evaluating. In this case it makes sense looking at the effectiveness, efficiency and satisfaction but if you’re for example evaluating a speech recognition system you might want to look at intelligibility instead.

2. What role will
prototypes play in research?
I think that a prototype plays a role in research in the sense that it helps create environment which can be more easily evaluated and understood. So if using a prototype one might discover flaws in a system or platform that might not have been discovered if using only questions or such.

3. Why could it be
necessary to develop a proof of concept prototype?
I’m not really sure if this questions regards proof of concept prototypes in general or are referring to the article? Either way I assume that I could be necessary as a way of proving that a concept or theory actually works in reality and serves its proposed function.

4. What are
characteristics and limitations of prototypes?
In the article the prototype/test platform consists of a self-designed circuit board with a mock-up mobile attached to it. Clearly the prototype is not as sophisticated as a fully developed product would be, which could limit participants ability to give an answer that in a correct way corresponds to what the researcher is looking to find out.

5. How can design
research be communicated/presented?
By presenting statistical data in combination with charts, diagrams and mockups. If using prototypes it should clearly be presented in both text and pictures.

How
does a collaborative setting differ from a single user setting as regards
methodology used and the results obtained?
In the case of Auditory feedback in haptic collaborative interfaces it lets the participants interact when trying to solve their given task. This interaction might result in answers that might not have surfaced if the method was based on a single user setting. The results will also differ in the sense that even though both participants performed the same task they might have perceived it differently.

How can
qualitative and quantitative methods in the same study complement each other?
Using a qualitative study gives you an opportunity to further validate results you get from performing a quantitative study and to dig a bit deeper.

How can
using both subjective and objective methods give a better understanding of a
phenomenon?
To be able to define the value of results based on an objective method, one must have an understanding of the subjective experience of the participants. If for example the objective method is to use a time-test to measure how effective a system is (like the one in the article on auditory feedback), it might also be interesting to see how the participants perceived the performance (which they did), and see if these actually correlate.

Good and well-formulated answers! I agree with most of what you said. Regarding the limitations of prototypes, your example: "which could limit participants ability to give an answer that in a correct way corresponds to what the researcher is looking to find out. " might be true in some cases. However, I think that this is a duality issue because sometimes it can be good to refrain from developing too sophisticated prototypes in order to leave some room for contemplation and interpretation by the users.
