Designing an arcade machine for therapeutic or rehabilitation purposes requires a thoughtful approach to ensure it meets the needs of users with physical or cognitive challenges. Here are the key considerations:

1. Accessibility: The machine must be adaptable for users with limited mobility, featuring adjustable controls, large buttons, or touchless interfaces like motion sensors.

2. Engagement: Games should be visually stimulating and rewarding to maintain motivation, with progress tracking to encourage consistent use.

3. Motor Skill Development: Activities should target fine or gross motor skills, such as hand-eye coordination or balance, tailored to rehabilitation goals.

4. Safety: The design must prevent strain or injury, with ergonomic seating and non-slip surfaces for stability.

5. Customization: Options to adjust difficulty levels or game mechanics ensure inclusivity for diverse abilities and recovery stages.

By prioritizing these elements, therapeutic arcade machines can effectively support rehabilitation while making therapy enjoyable.
