1)  How did physically acting out help to explore ideas? 

Physically acting is like a stimulation of the real situation. It helps the designer to face the problem in a form which he can actually learn with his senses. This is more useful than sketching on the paper, because designers can see how people suffer from the frustrations and thus came up with ideas to deal with them.

2)  Did you refine your ideas and solutions to the problem through bodystorming? In what way?
Yes, we did. Though brain storming we found some of our ideas and solutions are not practical, or will make the thing even worse. For example, because of the limited space in an aeroplane, we can not simply make the seat flat and soft like a bed. And although aromatherapy help people sleep but not every like it.

Body storming helped us to find out negative aspects of the ideas more easily.

3)  What was difficult or challenging about bodystorming?
First is to have people. In the tutorial it’s easy to find 4-5 students, but when doing real design, it will definitely take some time to get a group of “actors”.

Then is to stimulate the environment and situation, which demand for tools and a venue. All these will have an impact on the result of bodystorming.

4)  Does body storming lend itself to certain types of problems? 

It is obvious that the more the problem is related to our bodies and physical actions, the more useful it will be. I think body storming lend to product design problems, but might not be that powerful when doing digital design like app interface.
