21) How did physically acting out help to explore ideas?
This technique help me simulate the surrounding environment, that is, the context we need  to take into account. So, we can conduct the actions when we use the design in this context and check whether it is feasible in a real world but not only in our imagination. For example, in last tutorial we tried to make the seats in the airplane staggering so that the room for each passenger could be expanded. We thought we were genius when we draw it on the paper. But when we started building the prototype with chairs, we found that it was a totally stupid idea because people in lower seats did get a larger room for legs while the higher seat passengers would be more uncomfortable for their feet hanging in the air and easily kicking the heads in the previous seats. And in this process we might come up with a new idea which we would never think of when we just sit there and brainstorm. But the problem is we cannot find enough stuff to make our imitation more precise, and therefore limit our body storming.

2) Did you refine your ideas and solutions to the problem through bodystorming? In what way?
Yes, we iterate acting out several times to improve our ideas and solutions. In the first round of body storming, we moved our design from the paper to the classroom and soon we found it had a lot of limitations so we started improving it. And then our design
evolve into different branches because each of our group had a different point of view, so we acted them out one by one so we could compare their advantages and shortcomings. And in the end, we combine the relatively feasible and innovative features into one design and test it with our bodies. In this way, the final design was born.

3)  What was difficult or challenging about bodystorming?
The most tough part for us is not enough materials to make a real context so we need to use our imagination to make up the remaining part and that might cause the inaccuracy.

In addition, it is hard for shy people to act out especially express their feelings with exaggeration. And so does it when people are not familiar with each other, it takes time to warm up.

4)  Does bodystorming lend itself to certain types of problems?
So far I don’t find any
mortal problems that force we give up this technique. However it depends on what kind of design we are doing and the preference of a certain group.
