An examination of adaptive behaviour in the relationship between users and computer aided design (CAD) systems with specific reference to the textile industry.
The research involves the testing of Overall and
Experimental Hypotheses concerning the nature of design
activity and the relationship between designers'
cognition and their use of CAD systems. In particular,
a lack of understanding of the design process was perceived
together with a need to utilize aspects of designers
internal problem solving capabilities in the specification
of electronio design aids.
A multidisciplinary approach is used in review and
experimental methods in order to associate theoretical
aspects of design behaviour with the measurement of
practice. The social, economic and industrial implications
of new technology are reviewed in the light of their e~~ects
upon intellectual industrial tasks, such as designing
within the textile and other industries. Also considered
are the theoretical aspects o~ designing and in particular
the designers' cognitive activity is described in behavioural
terms. Such theories are tested in experimental situations
where the problem solving aspects are elicited from
designers in relation to their internal schematic representation
o~ design problems.
Speci~ic conclusions in the area o~ person-system
interaction concern both Hypotheses. Adaptation was ~ound
to be best considered as another aspect of the holistio
representation that a designer has of his task. This
resulted ~rom a recognition o~ the individuals own methods
o~ problem solving within the con~ines of the task. The
use o~ repertory grid techniques ~or the investigation of
designing did not prove however that a designer's internal
spaoe is completely measurable. Indeed, it resulted that
some phenomena associated with design appear ~undamentally
subjective although it was £ound that identi~iable and
individual oriteria are used by designers.
The particular contribution that this work makes is
in the assooiation o~ psychological, sociologioal and
industrial aspects o~ designing in an approach to the
adaptive behaviour of designers in their use of CAD "systems
