AI-driven ergonomic headwear customisation study for the Chinese population

Abstract

Amid the accelerating convergence of ergonomics, fashion and technology, the imperative for personalisation has emerged as a central determinant of customer satisfaction. Responding to this paradigm shift, this study investigates the collection, analysis and application of 3D head anthropometric data to advance the design of customised head related products for the Chinese population. To address this need, an AI-driven ergonomic headwear customisation system was developed between 2021 and 2024 that integrates two main components: (1) advanced 3D facial landmarking and head-prediction algorithms, which yield precise headwear-related parameters to optimise fit and comfort and (2) automated parametric design techniques, facilitating the seamless customisation of ergonomic headwear products tailored to individual morphological parameters and user preferences. Employing these methodologies, a comprehensive database of 3D head models for Chinese children and adults was established, a comfort prediction model for headwear products was constructed and an automatic, parametric headwear customisation system was implemented. The algorithms and models were rigorously validated through detailed applications to eyewear products. The findings demonstrate that by integrating affordability, accuracy and automation, the system significantly enhances product fit and user experience, thereby redefining the standards of headwear customisation. This research received HKD 2.2 million in funding from the Laboratory for Artificial Intelligence in Design (Project Code: RP1-3), Innovation and Technology Fund, Hong Kong Special Administrative Region. The research outcomes have been disseminated through five journal publications and one conference paper. The system has been recognised with one licensed patent and has garnered two international awards: the Silver Winner at the International Design Excellence Awards (IDEA) in 2023 and the Gold Medal with the Congratulations of the Jury at the 49th International Exhibition of Inventions of Geneva in 2024.
