Augmented reality instructions for construction toys enabled by accurate model registration and realistic object/hand occlusions.

ABSTRACT: BRICKxAR is a novel augmented reality (AR) instruction method for construction toys such as LEGO®. With BRICKxAR, physical LEGO construction is guided by virtual bricks. Compared with the state of the art, accuracy of the virtual-physical model alignment is significantly improved through a new design of marker-based registration, which can achieve an average error less than 1 mm throughout the model. Realistic object occlusion is accomplished to reveal the true spatial relationship between physical and virtual bricks. LEGO players' hand detection and occlusion are realized to visualize the correct spatial relationship between real hands and virtual bricks, and allow virtual bricks to be "grasped" by real hands. The major finding of the research is that the integration of these features mak
