Abstract

Augmented reality (AR) applied in education provides learners a possible way for better understanding and thorough learning. Although the traditional projector is used to integrate the augmented information with real objects without wearing AR glasses, the projector-based AR system is unlikely to be adopted widely in education due to the cost, heavy weight, and space issues. In this paper, an alternative projector-camera AR platform, utilizing a digital light processing (DLP) module matched with a Beaglebone Black (BB) controller, is proposed for AR physical experiments. After describing the DLP-based AR learning design method, the algorithm of pre-deforming projection content with simulation-based poly fitting is presented to keep the virtual asset consistent with the user action; and then a prototype with the content regarding the thermal management of power devices is illustrated to validate the performance of the AR experimental platform. The result shows that the DLP-based AR platform is an accurate and interactive AR system with a response time of 1 s, and a registration deviation of 3 mm. It is also an affordable AR learning design tool with a bill of materials of about $200, and thus casts light on creating AR-based physical experiments to explore more physical phenomena.
