Brain-computer interfaces (BCIs) are transforming arcade machines into futuristic gaming experiences by enabling mind-controlled gameplay. One of the most innovative applications is neurofeedback-based games, where players control characters or actions using their brainwaves, eliminating the need for traditional controllers. Another breakthrough is emotion-sensitive arcades, which adapt difficulty levels or storylines based on the player's mental state, creating a personalized experience. Multiplayer BCI arcades allow players to compete or collaborate using their brain signals, adding a new layer of interaction. Additionally, BCIs are being used to enhance accessibility, enabling individuals with physical disabilities to enjoy arcade games. These advancements are pushing the boundaries of interactive entertainment, making arcade machines smarter and more immersive than ever before.
