Toward Creative 3D Modeling: an Architects' Sketches Study

International audienceThis paper describes our methodology in providing designers with a new advanced 3D modeling Human-Computer Interaction. The main project - called GINA, a French acronym for Interactive and Natural Geometry - expect to introduce new intuitive and creative 3D modeling tools, relying on 2D perspective drawing reconstruction. We present here the user study we conducted and the implications of this study on the interface of GINA
