DEVELOPMENT OF A DESIGN SUPPORT SYSTEM FOR OFFICE CHAIRS USING 3-D GRAPHICS

This paper describes the research and development work done on a desig n support system intended for use as a support tool in designing offic e chairs. Subjective evaluations were conducted using the semantic dif ferential (SD) method to examine the relationship between users' perso nal assessments of office chairs and design elements. The results obta ined were then quantified by means of multivariate analysis and incorp orated in a database. As a result, this system can indicate the design elements needed to create a given chair design. A chair design is out put in a graphical representation in response to an adjective input. B ecause the graphical representation is composed of 3-D data, it is pos sible to display the design from any desired perspective and also perf orm shading and other operations.
