The assembly instruction is a mandatory component of Lego-like brick sets.The
conventional production of assembly instructions requires a considerable amount
of manual fine-tuning, which is intractable for casual users and customized
brick sets.Moreover, the traditional paper-based instructions lack
expressiveness and interactivity.To tackle the two problems above, we present
BrickPal, an augmented reality-based system, which visualizes assembly
instructions in an augmented reality head-mounted display. It utilizes Natural
Language Processing (NLP) techniques to generate plausible assembly sequences,
and provide real-time guidance in the AR headset.Our user study demonstrates
BrickPal's effectiveness at assisting users in brick assembly compared to
traditional assembly methods. Additionally, the NLP algorithm-generated
assembly sequences achieve the same usability with manually adapted sequences.

利用增强现实技术的 BrickPal 系统，结合自然语言处理技术生成装配指南，通过 AR 头显提供实时指导，有效地帮助用户进行积木组装，NLP 算法生成的装配序列与人工调整的序列有相同的可用性。
