According to LARPS, the stage setting and sound have a great influence on the performance. I totally agree with it since visual sense and audio sense receive most of the information around us. Take the show BASU as an example, although the stage is very small, once the props and costumes are selected properly, the whole stage setting looks differently. Besides, interactive performance is hard to predict because the audiences may respond differently, so it is necessary to make it stable, for example, set the main story and provide the audiences with limited options. In BASU, the host sometimes asks the audiences to give the word like occupation or animal, and then the actors will make up a story that includes those words. It is a useful strategy to maintain stability during the performance.
