PlayStation Move is a motion-sensing game controller developed by Sony for the PlayStation 3 and later compatible with the PlayStation 4. It uses a combination of a camera and handheld controllers to track player movements, allowing for an interactive gaming experience. The controllers feature a glowing orb that changes color, providing visual feedback during gameplay. The system was designed to enhance gameplay by allowing players to physically engage with games, similar to other motion control systems like Nintendo Wii. It supports a variety of games, including sports, fitness, and adventure titles, making it versatile for different gaming preferences.
