Biometric feedback is revolutionizing the arcade gaming industry by creating immersive and interactive experiences. One of the most innovative uses is heart rate monitoring, where games adjust difficulty based on the player's stress levels, ensuring a tailored challenge. Motion tracking, combined with biometric sensors, allows players to control games using body movements, making gameplay more dynamic. Some arcades now use facial recognition to personalize in-game avatars or trigger special effects based on emotions. Another breakthrough is sweat and skin conductance sensors, which measure excitement and adapt gameplay in real-time. These advancements not only enhance engagement but also pave the way for future gaming innovations. As technology evolves, biometric feedback will continue to redefine how players interact with arcade games.
