アクセアクセシビリティを考慮した建設機械の設計改善

―調査結果と開発要件の明確化―

This study addresses accessibility challenges in the design of construction equipment, aiming to improve usability for individuals with physical disabilities. Despite the construction industry's focus on usability, challenges persist in usability for certain groups. Preliminary research revealed issues with boarding, seating stability, and operation of existing equipment, and the possibility of people with disabilities engaging socially via accessible construction equipment. The study identified individuals with spinal cord injuries Type I (hemiplegia) and amputations as primary target users, with those having Type II (quadriplegia) as secondary targets. Through online surveys, it investigated their specific needs, uncovering a demand for construction equipment in daily activities. Interviews with target users highlighted design requirements including low seat height for easier transfer, minimal third-party support, operability with upper limbs or fingers, and features supporting body stability. The findings defined the target users and detailed design requirements for construction equipment accessible to individuals with physical disabilities.
