Personalized modifications of vehicle interiors for social inclusion

Abstract

Limitations in vehicle interior design restrict independent mobility for individuals with hand-related difficulties, reducing accessibility and social inclusion. This study presents a digitally driven methodology for developing personalized and inclusive vehicle interior solutions through the integration of 3D scanning, virtual ergonomics, and additive manufacturing. The research addresses geometric and ergonomic constraints in conventional vehicle interiors and translates user-specific anthropometric and functional requirements into optimized design interventions. The proposed workflow combines design thinking with ethnographic research, reverse engineering, ergonomics, and anthropometry. Following an analysis of existing inclusive solutions, qualitative user study identified task-specific limitations and usability requirements. Specific control elements in the vehicle interior are digitized using structured-light 3D scanning, while user anthropometric data and functional grip parameters are integrated into digital models. These datasets are evaluated in a virtual ergonomics environment to simulate user–vehicle interaction and assess alternative design configurations. Based on simulation outcomes, customized assistive interior components are developed and fabricated using additive manufacturing. The resulting digital-to-physical workflow reduces iteration cycles, development time, and cost while improving functional accuracy and user satisfaction. The methodology is applicable across a wide range of inclusive mobility and product design scenarios.
