Fragile Intersections is an interactive performative installation based on voice, movement, dance, biosignals, artifacts, and visual projections. It premiered in October 2021. This article describes the development of its three interrelated parts: two interactive and autonomous artifacts that capture and re-signify corporeal signals of the participants, and a performance by a dancer, who becomes an agent for subtle forms of dialogue with the installation. The authors discuss the characteristics of Fragile Intersections as a system founded on the dynamic relations of its different components, where multiple meanings and subjective processes appear during the exploration in this hybrid space of an installaformance.
