This document proposes an interactive art installation called "Personal Space: Crossing Digital Boundaries" that explores the concept of personal space in the digital realm. Viewers can physically interact with and affect the movements of a projected digital person. The piece is inspired by precedents that examine blurred lines between virtual and real, user physical interaction, and how viewer actions impact outcomes. Next steps include prototyping the technology, choosing an environment, and determining the digital person's movements and interaction triggers.
