Arcade machines and interactive olfactory displays represent two distinct forms of entertainment technology, each offering unique experiences. Arcade machines are traditional gaming devices that focus on visual and auditory feedback, often featuring joysticks, buttons, and screens to engage players in fast-paced games. In contrast, interactive olfactory displays incorporate scent as a primary sensory element, creating immersive environments by releasing specific aromas in response to user actions or scenarios.

While arcade machines prioritize gameplay mechanics and high scores, olfactory displays emphasize multisensory engagement, often used in museums, therapy, or marketing to evoke emotions and memories. Arcade machines are standalone units, whereas olfactory displays are typically integrated into larger installations or digital interfaces. The key difference lies in their sensory focus: arcade machines appeal to sight and sound, while olfactory displays target the sense of smell for a more nuanced and emotional experience. Both technologies showcase the evolving landscape of interactive entertainment.
