Alterface, a leader in interactive technology, has contributed its new generation interactive pointing system to Phantom Theater: Opening Nightmare at Kings Island, Ohio.

Designed and manufactured by Sally Dark Rides, the experience invites visitors on a comedic family adventure set within the haunted Phantom Theater.


When a lightning strike releases the 'ghost notes' from Maestro’s pipe organ, guests use spellbound flashlights to capture the musical spirits and return them to the organ, allowing the performance to begin on time.

Alterface's technology brings ultra-low-latency performance and high-precision tracking, enabling a totally immersive flashlight-based gameplay experience.

The system delivers highly responsive feedback between visitor input and on-screen reactions in as little as 30 milliseconds. This level of performance ensures a seamless, intuitive, and natural interaction.

Guests can 'shine' the light with precision, revealing features within the environment without causing disruption.

The gameplay goes beyond typical hit-based mechanics to concentrate on continuous interaction, exploration, and discovery.

Integrated interactivity

The experience brings physical sets, animatronics, and projection mapping together with real-time interactivity across 26 highly detailed scenes.

The result perfectly melds classic dark-ride artisanship and cutting-edge interactivity, where discreetly deployed technology strengthens the narrative.

Phantom Theater: Opening Nightmare is the result of an innovative concept by Sally Dark Rides, which set out a new approach to gameplay with a balance of traditional dark ride storytelling and cutting-edge interactivity.

This concept guided a smart refurbishment strategy that reused the existing ride system while directing investment towards the elements that guests directly experience, such as scenery, animatronics, and interactive content.

Instead of adding isolated interactive elements, the experience integrates interactivity directly into the storyline, resulting in a coherent and enhanced visitor experience. This is both a refresh and a faithful adaptation of the original attraction, enabling longtime fans to rediscover a much-loved ride in a new form.

"Our technology enables this agility, offering the precision and flexibility needed to support every new bold idea our partners can imagine."
