Latent Projections is an ongoing exploration of biofeedback brainwave technology as well as a poetic speculation on the spectrums of memory. Each image and video in the series frames a kind of internal portrait, externalizing into color the electrical phases of the mind as it recalls various events from the past or visions from the future. On a material level, the project explores dormant and invisible aspects of memory found in the crystal structures of water and oscillating signals in the human body.
Participants were asked to keep a bottle of sterilized water as close to their body as possible for 24 hours, including sleeping with it under their pillow. After having dreamt next to this water, it was frozen in a circular mold and allowed to crystallize, revealing unique structures for each person. The participants were then wired to an EEG device, and asked to recall their dreams of the future or favorite activities of the past. Their EEG signals were recorded and fed through a custom-built software which translates the five defined brainwave bands into their corresponding color harmonic frequency as follows : Delta (0.1 - 3.5 Hz) gets mapped to the color red (400-484 THz), Theta (4-8Hz) to orange (484-508 THz), Alpha (8-12 Hz) to green (526-606 THz), Beta (12-30 Hz) to blue (606-668 THz) and Gamma (30-100Hz) to violet (668 - 789 THz). Each second, the dominant brainwave in the data generates it corresponding color, producing a portrait of streamed colors of each participant’s memory recall session. Finally, this generative color portrait is projection mapped to illuminate and refract through their unique crystal ice formations. The final images and videos are records of these latent projections, revealing the cycles and hues of the invisible affects of memory.
When experiencing the work in its installation context, the viewer is confronted with planetary-scale projections of slowly emerging and shifting hues of light and ambient sound. Photographs of the final portraits are also present as still prints. Some iterations of the project have included performances of live-brainwave data projection-mapped onto the blocks of ice.
