This paper explores the way designers use body movements to support mental imagery while solving design problems. Given the task of designing a handout place for students on campus, this paper will identify and compare the unique strategies by which the architect developed the design using his body as a crutch to take visuo-spatial decisions when blindfolded and prevent them from using their usual thinking tools like sketching. This experiment is an attempt to reveal the invention of design issues and requirements using body movements, which have relevance to mental imagery.
