Abstract
We describe new techniques to allow constraint driven design using spatial augmented reality (SAR), using projectors to animate a physical prop. The goal is to bring the designer into the visual working space, interacting directly with a dynamic design, allowing for intuitive interactions, while gaining access to affordance through the use of physical objects. We address the current industrial design process, expressing our intended area of improvement with the use of SAR. To corroborate our hypothesis, we have created a prototype system, which we have called SARventor. Within this paper, we describe the constraint theory we have applied, the interaction techniques devised to help illustrate our ideas and goals, and finally the combination of all input and output tasks provided by SARventor.
To validate the new techniques, an evaluation of the prototype system was conducted. The results of this evaluation indicated promises for a system allowing a dynamic design solution within SAR. Design experts see potential in leveraging SAR to assist in the collaborative process during industrial design sessions, offering a high fidelity, transparent application, presenting an enhanced insight into critical design decisions to the projects stakeholders. Through the rich availability of affordance in SAR, designers and stakeholders have the opportunity to see first-hand the effects of the proposed design while considering both the ergonomic and safety requirements.
