Refrival partnered with Yellowbricks TRISON to redefine audience participation at large-scale festivals. Through HEICam, attendees became active protagonists, interacting directly with live content displayed across the event’s screens.
The challenge was to generate engagement at large festivals, offering attendees interactive digital dynamics that would enrich the overall experience of the event without interfering with their enjoyment.
TRISON Yellowbricks developed the HEICam platform, which allows user registration, participation in games, polls and contests, and displays the results in real-time on the festival’s screens, creating an interactive and immersive experience.

HEICam creates a direct connection between the audience and the event. By enabling users to upload content and interact instantly, the platform transforms spectators into protagonists and amplifies collective participation across large-format screens.
Technology, creativity and participation converge to turn festival audiences into the heart of the live experience.
HEICam is designed to operate in high-demand environments, supporting thousands of simultaneous users. Its administration panel enables content moderation and flexible activation formats—selfies, contests or quick polls—adapting seamlessly to different festivals and brand objectives.

With HEICam, Refrival and Yellowbricks TRISON redefine festival engagement, transforming participation into the most powerful live attraction.
