An Assessment of Industrial Designers Use of Human Factors Criteria in Product Design Evaluation

In order to know the pattern of actual application of human factors criteria by industrial designers an experiment was conducted by asking 87 students of industrial design to evaluate a CAD workstation after completing a course in “human factors in design”. The guidelines chosen for the evaluation were those related to design of visual displays, controls and workstation layout on the CAD system. Since the main objective was to see how many of the principles had become part of their “common sense” they were asked to evaluate the equipment without any reference to any books/notes.

The subject's responses were compared with the human factors guidelines using a Chi-square test (0.05 significance). The results pointed out that industrial designers readily accepted general criteria such as visibility, operability, and accessibility but interpretability of the display was frequently unrecognized. Such information could be used by industrial designers and human factors experts to improve their cooperation in the design process and thus increase the acceptance and marketability of the product.
