Abstract

The research deals with two main questions: 1.the role of visual displays in the process of design problem solving. The hypothesis is that the presence of visual displays (sketches and diverse environmental stimuli) enhances design problems solving. 2.The role of sketching in the process of design problem solving. The hypothesis is that sketching enhances design problem solving, and in particular sketching without additional visual stimuli enhances design problem solving more than does the presence of sketches as display, when sketching isn't possible.


In order to test the hypotheses an empirical experiment was conducted. 36 subjects were asked to design two products (packaging for candies and a drinking fountain) within a limited amount of time. The subjects were divided into three experimental groups: 1.an environment with no specific visual stimuli. 2.an environment rich with diverse visual stimuli 3.an environment wherein sketches created by other subjects provided visual stimuli. Half the subjects in each group performed the task while sketching, whereas the other half did so using visual imagery solely.


The subjects' drawings were assessed for originality, practicality and general quality. The research hypotheses were partially confirmed:


1.A contribution of diverse environmental stimuli to the quality of designs was found only for originality scores in the design of packaging.

2.A contribution of sketches as displays  was found only for originality scores of drinking fountain

3.A contribution of sketching was found only for practicality scores of drinking fountain.

4.A contribution of sketching as compared to watching sketches created by others was found was found only for practicality scores of drinking fountain.
