Designing arcade machines for rehabilitation centers presents unique challenges that balance entertainment with therapeutic benefits. One major challenge is ensuring accessibility for patients with varying physical abilities, requiring customizable controls and adaptive interfaces. Another hurdle is maintaining patient engagement over time, which demands dynamic, rewarding gameplay tailored to rehabilitation goals. Additionally, integrating data tracking for progress monitoring without disrupting the gaming experience is complex. Finally, cost and space constraints often limit the deployment of such specialized equipment. Addressing these challenges is crucial to creating effective, enjoyable, and sustainable therapeutic gaming solutions.
