title 3D CAD modeling using gestures and speech: Investigating CAD legacy and non-legacy procedures
source Ji-Hyun Lee (Eds.) "Hello, Culture!"  [18th International Conference, CAAD Futures 2019, Proceedings / ISBN 978-89-89453-05-5] Daejeon, Korea, pp. 347-366
summary 3D CAD modeling using natural interaction techniques necessitates greater research into the modeling procedures employed by users. In a previously conducted experiment, we elicited speech and gestures input for 3D CAD modeling tasks for conceptual design. In this paper, we examine the 3D modeling procedures articulated by the participants, using gestures and speech, for creating basic 3D models of increasing complexity. We identified 3D modeling procedures and characterized them as CAD legacy and non-legacy procedures. Results show that (1) non-legacy procedures were employed by a considerable number of participants who had fair and high proficiency in CAD and (2) Non-legacy procedures with fewer steps were rated favorably by participants. Based on the results, we provide recommendations on key aspects of non-legacy procedures that need to be incorporated in CAD modeling programs to facilitate speech and gestural input.
