Abstract
Introduction
This article presents an innovative approach to the development of contour-based products, such as assistive technologies, with postural readjustment. The process integrates advanced techniques of three-dimensional scanning, digital modeling, and 3D animation.
Objective
To develop a method that employs digital human models obtained through 3D scanning, applying modeling and animation techniques to digitally adjust posture and enable the digital fabrication of custom-fitted products with postural correction.
Method
The method was developed following an action research framework, encompassing its design, application, and refinement through a case study that illustrates its practical use.
Results and Discussion
The case study describes the development of a custom seat with postural realignment for a wheelchair user. The development is structured into five stages: (1) Application Requirements; (2) 3D Scanning; (3) Digital Model Processing; (4) Digital Fabrication; and (5) Evaluation. For each stage, technical possibilities and real-world challenges are presented based on the case study that demonstrates the complete implementation of the method.
Conclusion
The proposed method proved to be effective, enabling the production of high-quality seating with accurate postural adjustments. This contribution opens new avenues for research and practice in the field of assistive technology by enabling faster and more precise product development. It keeps pace with the latest advances in product design and healthcare, supporting professionals in delivering better care, and benefiting a greater number of people with disabilities.
