    摘要: Augmented Reality (AR) technology is a fast growing field in the academics and industry. This paper presents a novel design of an interactive assembly teaching aid based on a multi-template AR system, which consists of three units: a multi-template AR unit, an online three-dimension (3D) model assembly unit, a hand-gesture interaction unit. The design of the multi-template AR unit employs an efficient multi-template pose tracking method to detect and track multiple template images simultaneously. The online 3D model assembly unit is enabled, when the pose of each target template is tracked and computed by the multi-template pose tracking method. This method measures the distance between the two templates to determine the 3D rendering mode of the virtual object. The third unit aims to realize a vision-based human-computer interactive system, which combines the AR rendering system with the real-time hand-gesture recognition method to decide the status of AR rendering of a 3D dynamic animation according to the user’s hand gesture. Based on the feedback of twenty-one users of the AR-based interactive teaching-aid, it can be concluded that the system creates an interactive experiences that engages the users and facilitates them to increase their learning interest significantly. In future, we plan to port the proposed AR system to Android and iOS mobile devices while improving the functionality, interactivity, and entertaining qualities of the teaching aid system.
