Towards intelligent early form design and prototyping, questionnaire results and analysis

Abstract

Currently, the Department of Manufacturing Engineering (DME), University of Malta and the Istitito per la Matematica Applicata e Tecnologie Informatiche (IMATI), Genoa are conducting research on how simple components represented by sketches on normal paper can be converted to computer models. One of the key issues in developing a sketch recognition system is precisely to handle the trade-off between ease of computer recognition and the preservation of sketching freedom. With an attempt to address this issue, two sketching methods (or sketching languages) have been developed by the DME. This report presents the results of a questionnaire about the sketching activity itself and also about the two proposed sketching languages. An analysis of the results obtained is also presented with the scope to identify what should be the future directions that might contribute to enhance the usefulness of the two sketching approaches
