Dorta’s (2004) and Goldschmidt’s (1992) work highlights two main phases in ideation, corresponding to different constraints: the reflection-in-action phase, during which the designer needs tools that allow him or her to represent his or her ideas quickly and with natural gestures, even if this leads to a very imprecise result. For this purpose, the traditional tools used are paper and pencils, whether in the form of Post-it notes, flip charts or notepads. As we will detail later, virtual reality tools such as Time2Sketch are particularly well suited to this phase since they allow freehand 3D drawings to be made quickly and easily in the appropriate virtual environment. The second phase concerns the asynchronous collaboration, and implies that the designer realizes one or several “presentation sketches”, that is, more precise and communicable representations of their ideas. This phase is usually done with CAD software. However, among virtual reality tools, software such as Time2Teach – enabling 3D animations to be created quickly using integrating flows – and Time2Craft – a virtual reality CAD module – enable this design step to be accelerated.
