CONSIDERATION AND MODELING OF USE PROCESSES INCOMPUTER-AIDED CONCEPTUAL DESIGN: A STATE OFTHE ART REVIEW

摘要

If conceptual modeling and simulation of consumer durables could include consideration of usernprocesses, designers could more successfully anticipate the interaction of products with users in arnuse environment. This is the basic idea behind our research into computer-aided modeling andrnforecasting product-use processes. This survey investigates the current state of the art, that formsrnthe basis for companies or researchers developing systems in this area. It includes overviews of (a)rndefinitions (b) relevant achievements in this field, and ( c ) research in related areas, such asrnergonomics, human-computer interaction and machine design. In recent years, there has been nornsignificant development of novel, dedicated use-process models. Current models represent discreternactions, observed from use of existing products or prescribed by the designer. Simulationrntechniques are applied to deal with continuous changes, predicting the behavior of the product andrnits environment, but typically not the user. Yet, promising techniques for simulating humans arernemerging, for instance in computer-graphics animation. New integrated techniques for simulationrnopen the way to quantitative and more accurate predictions of the use process, but they cannotrnhandle the multiplicity of possible use processes resulting from different users in differentrnenvironments. In this respect, the development of use-process models with increased knowledgerncontent and facilities for integration with simulations can give a solution.
