Abstract
This presentation explores the development of a foot guard for simple electric wheelchairs, enabling individuals with disabilities to play soccer. Initiated by a child's desire and driven by user needs over 11 years of iterative DIY and collaborative efforts involving persons with disabilities, their supporters, special needs schools, sports centers, and wheelchair manufacturers, the “Fan Guard” was successfully commercialized in 2025. This project exemplifies person-centered design, emphasizing simple technology, adaptability, affordability, and continuous user feedback. The presenter, a rehabilitation engineering technician, reflects on this clinical-practice-driven approach to assistive technology development, contrasting it with traditional designer/manufacturer-led models and aligning it with theories of “Tojisha Design” (design by those concerned). This case study offers insights into fostering user-driven innovation and sustainable projects in assistive technology.
