Designing arcade machines for mixed-reality (MR) experiences presents unique challenges that blend physical and digital worlds. One major hurdle is hardware integration—ensuring robust, high-performance components like motion sensors and VR headsets work seamlessly within the arcade’s compact structure. Another challenge is creating immersive gameplay that balances physical interaction with digital elements, avoiding disorientation or motion sickness. Additionally, durability and maintenance are critical, as MR arcades face heavy public use. Finally, cost-effective scalability remains a barrier, as cutting-edge MR technology often comes with high production expenses. Overcoming these challenges is key to revolutionizing the future of arcade gaming.
