Designing arcade machines for universal accessibility presents several key challenges. First, physical accessibility is critical, as machines must accommodate players with mobility impairments, requiring adjustable heights, wheelchair-friendly designs, and easy-to-reach controls. Second, visual and auditory accessibility demands high-contrast displays, customizable sound options, and tactile feedback for visually or hearing-impaired players. Third, cognitive accessibility involves simplifying game mechanics and providing clear instructions to support players with learning disabilities. Additionally, cost and space constraints often limit the feasibility of implementing these features. Finally, balancing inclusivity with the fast-paced, competitive nature of arcade gaming remains a significant challenge. Addressing these issues ensures that arcade machines can be enjoyed by everyone, regardless of ability.
