Abstract
Augmented reality (AR) is a novel technology which overlays computer-generated information seamlessly on the real-world environment. AR technologies have opened up a powerful set of tools for computer-aided assembly planning. This paper presents a manual assembly design system using AR technologies. An assembly data structure is devised for assembly information management. Algorithms for assembly constraint recognition and assembly location refinement have also been proposed. A hybrid approach based on these methods has been formulated and implemented to allow the users to simulate a manual assembly without the need for auxiliary computer-aided design information in assembly design. This would result in enhanced user experience and reduced preparation time. A methodology for 3D bare-hand interaction is integrated with this interactive manual assembly design system for the users to manipulate the virtual components in a natural and effective manner. A prototype system for interactive manual assembly design has been developed. An example has been provided to demonstrate the developed prototype system.
