Design and Technology: The Comparison between Visual Thinking using Computer and Conventional Media in the Concept Generation Stages of Design Introduction The utilisation of three-dimensional computer-aided design has developed into a routine practice in most design fields including architecture, engineering, archaeology and conservation.
Research has been done into computer-aided conceptual design which has been undertaken with quite successful results adoptable to industrial design but the visual thinking undertaken when sketching has not been investigated to significant detail. A critical analysis of a study into the cognition and visual thinking of designers in computer-aided design and how this compares to conventional media concept generation is useful in development of headways in the design of online learning environments. The study analysed here-in compares and contrasts computer-aided and conventional media in concept generation in design and whether there are any performance differences when using the two. Background Narayan et al. (2008, p. 3) defines computer-aided design as any type of design activity that makes use of a computer to develop, analyse or modify an engineering system. The designer creates an image on the computer using geometric elements including lines and circles. Manipulations on the image can then be undertaken through magnification, reduction in size and rotation or other methods until the desired modification is achieved. The impact of computer-aided design on traditional design has been grand with new areas being opened up including shape grammars, database system design, expert systems and knowledge-based systems (Won 2001, p. 320). ...
