Lumina is an interactive installation that aims to generate a sense of presence by exploring the personal and peri-personal space of the user. During Bartlett 2019 Design for Performance and Interaction (DfPI) Project Fair, visitors to the Lumina installation were given tracking wearables that registered their bodily positions and postures. When they entered the dark enclosed space where Lumina was hung, they then would be given a pair of headphone through which Bu Ert Joroin by Olafur Arnalds (2003) was playing. As they stood underneath Lumina, their positional data was then collected and manifested into different compositions, colours, and intensities of eight light rays that moved around them from above, forming a cone shape. While Lumina is a single user experience, the light made the use’s bodily presence visible to others. Lying or sitting down on cushions on the floor, other visitors watched the user interacting with Lumina as a performance while waiting for their turns to experience it.
