Abstract: An attraction system includes a display that operates to present augmented reality and/or virtual reality (AR/VR) imagery to a guest in an interactive space. The system includes an audio controller that operates an array of speakers that are distributed throughout the interactive space and a controller having one or more processors. The one or more processors are operable to receive data indicative of a state of the guest (e.g., an action, movement, or gesture of the guest, an input received from an input device). The one or more processors are also operable to adjust the AR/VR imagery in response to the state of the guest, and instruct the audio controller to operate the array of the speakers to provide interactive audio based on the state of the guest and such that the interactive audio presents to the guest as though originating from a dynamic portion of the AR/VR imagery.
