2D and 3D conceptual design sketching: interface, modelling and progress

Abstract

The creative process is often inspired by natural and cultural worlds and further supported by the immediacy of the presentation, the ease of manipulation, and the possibilities of tracing the development of ideas or revisiting them in order to explore other possible routes. The use of design sketches or drawings to represent design ideas is crucial to the creative process. Sketch-based design technology has the potential to create a seamless transition from conceptual design to a manufactured product. This talk will present an overview on 2D sketch-based interface and modelling pipelines: stroke filtering and processing, 2D tidy-up, visual perception, 3D understanding and modelling. The talk will also review 3D sketch-based interfaces for modelling and interaction: 3D sketching with VR perceptions, 3D sketch with gesture tracking and mixed design environments. The talk will finally discuss the challenges ahead and implications in conceptual design.
