In many cultures, the eyes are said to be a window to the mind or even to the human soul. In this project, no such claims would be made, but an attempt is made to find the relationship between the mental image in a designer's mind and his eye movements. The role of visualisation and mental imagery during the early creative phase in design problem solving has already been established in previous papers (U. A. Athavankar, Singh A., Hiremath M). However, in these experiments, the subjects were blindfolded and asked to solve the design problem. They were restricted from sketching their ideas and, hence, had to rely on their mental imagery to develop ideas. The entire process appeared as if the designer was conceiving a shape in the mind's eye and kept modifying and shaping it throughout. In an experiment done on an industrial designer (U. A. Athavankar, 1997), where he had to design a casserole, it was observed that the subject used a large number of gestures to shape the object. This study was carried out to understand the role of gestures in imagery and in modelling 3D shapes using a hypothetical intelligent system.
