This study explores the concept of screen-performance as a sensory and performative interface in interactive media content. Moving beyond the traditional notion of the screen as a passive display, it examines how screens can function as spatial, real-time systems that engage users’ bodies and perceptions. Based on theoretical research on screen media and performativity, the paper analyzes two original media artworks—Light, Movement of Boundaries and Boundaries: Coexistence—as case studies. These works demonstrate how screen-based installations can incorporate sensor feedback, adaptive visuals, and embodied participation. The findings suggest that screen-performance offers a meaningful framework for designing immersive user experiences in media art, interactive installations, and game environments.
