3D freeform design is one of the most challenging tasks to support in a software application. Even the conceptually simplest 3D forms can be difficult to produce with existing applications. We have been exploring alternative input devices and new interaction paradigms to better support the initial design process of 3D design, from large display systems to pure-inference sketching interfaces.
Designing user interfaces for interacting with 3D data involves a number of factors that are not found in traditional 2D interfaces. In this project, we explore subtle yet critical aspects of 3D control and feedback. A number of research outcomes have been integrated into several Autodesk products and we continue to explore this complex area.
