HALO: Wearable Lighting

Abstract

What if lighting were not fixed to our architecture but becomes part of our body? Light would be only where it is needed. Buildings would light up brightly when busy, and dim down when people leave. Lighting would become more energy efficient, more personal, and colorful, tailored to individual needs. What applications beyond illumination would be possible in such a scenario? Halo is a wearable lighting device that aims to investigate this question. More specifically Halo explores the potential of body-centered lighting technology to alter appearance and create a personal space for its wearer. A ring of colored LEDs frames the wearer's face, putting her into the light she desires. Borrowing from both theatrical and photographic lighting design, Halo has several different lighting compositions that make the wearer appear happy, sad, energetic, mysterious, etc. Using a smart phone application, the wearer can switch between these modes. She can also let the application adjust automatically depending on her activities. Halo is an experimental technology that combines function and fashion---a platform to probe the future of wearable lighting.
