Rainbow Resonance is a computer vision installation that generates colors and musical sounds of the equivalent sound frequencies in the electromagnetic spectrum, according to the motion of the participator. The color to sound mapping is based on a custom Pythagorean tuning system.
Aural Aura – Wireless Communication
Wireless Communication with the BUG
Wireless communication with BUGbees
The BUG serves as the central hub for processing data at the hardware level using sensor data and bugbee readings. Three bugbees are attached to the bodysuit for location identification purposes using the method of triangulation. My programming partner Dr. Constantinos Hadjiloizis and I have successfully tested wireless communication between the BUGbees and the BUG motion sensor using the dragonfly interface. To test the BUGbees I physically attached them to my body, two on each arm, and one below the stomach. We will use the dragonfly interface to open a port of communication between MAX/MSP and the bug. The BUGbee readings are analyzed and compared with sensor data readings transmitted via the xbees and packaged in MAX/MSP, to ensure a more accurate datastream in order to determine movement and location. We are also conducting testing using the Von Hippel interface, which allows us to use the Arduino open-source platform, as an alternative to wireless communication, for comparison and testing purposes.

Aural Aura
Aural Aura in Development
Harvestworks July 09
Current developments I am currently in the process of replacing the flex sensors with hand made sensors made from neoprene and velostat. I am also examining the possibility of eliminating body sensors in favor of a more sophisticated motion tracking system with the camera, which allows the precise identification of specific moves. At the same time I am implementing RGB LEDs mapped to the chakra points on the body suit, which are illuminated through the astral body dress at the precise moment when each chakra is triggered.
Aural Aura
Aural Aura is a computer vision and sound installation/performance that visualizes color frequencies and sonifies resonances of key energy points of the body, generated through movement and triggered using sensors. The project aspires to enhance energy management through a mapping of color, sound and movements based on the Shaolin 18 Lohan hands, the fundamental chi Kung exercises used for meditation since 527 BCE in China. Active and/or passive bodily movements trigger specific sound frequencies and colors mapped to the chakras. The goal of Aural Aura is to to unite sound, color and dance in a fluidly attuned communion that transcends the performer, and ideally the audience into a hyper reality that approaches a spiritual experience.
The Structure
The nature of Aural Aura is fivefold involving computer vision, a wearable interface, an astral body projection, musical compositions and sensors.
The Bodysuit
The bodysuit is the controller and generator of sounds and visual effects according to the readings of the attached sensors. A choreography of 8 moves measured by the sensors, determines the triggering of sounds, and images. The sensor bodysuit acts as an instrument capable of playing the 8 tone scale resembling the lydian mode scale, that is, the white keys of the piano. Choosing a wearable interface as an event based generator for mapping gestures was necessary in order to identify and associate chakra to sound and color.
A very special thanks to Andrea Lauer whose contribution made the execution of the design of the body suit into a costume possible.
The Gloves
A pair of gloves use two Flex sensors, one soft potentiometer, one FSR and soft switches, to provide continuous controllers and switches affecting rhythm, pitch, reverb and delay. The gloves went to multiple design variations. In the final design of the glove I used soft switches made of conductive fabric and tightly swed the remaining wire wrap onto the surface of the glove. For an update please check the link Musical Gloves.
The second variation of the glove replaced conductive thread with wire wrap. The glove connections were too loose and the readings were inconsistent.
The first variation of the glove involved conductive thread which shorted the circuit. 
The Astral Body
An exoskeleton wearable layer, the astral body dress, physically extends outwards from the central bodysuit, representing the aura and serving as a canvas for projecting images. The astral body dress is used for projection to visualize the aura in three dimensional space rather than on a screen. Visual effects projected on screen merge with the astral body dress color effects to simulate the aura.
Computer Vision
As computer vision tracks movement, the screen/body projection reflects chakra points being triggered by glowing the equivalent colors and/or symbols, while corresponding sounds are generated in realtime.
The Sound
The musical compositions attempt to capture the ethereal aspect prevalent in the visual representation of the aura. The estoreric aspects of music inform the process of sound design as different energy points are mapped to distinct instrumental sounds and musical intervals based on the Pythagorean tuning system. Sounds convolve harmoniously into each other as gestural movements trigger different energy points (chakras). Pure oscillators are synthesized into alpha and delta vibrations, intervals and resonances that accompany the choreography of movements. The low vibrational frequencies used help induce meditative states. Sound does not accompany the dance but is instead created by the dancer.
Technology
- Hardware:
- Xbee radios wirelessly transmit the readings from the body suit and gloves sensors to a base station radio that communicates serially with the computer.
- Sensors – Eight Flex sensors, one accelerometer, a stretch sensor are attached onto the performance Body suit to measure and map movement, and subsequently to trigger sounds and color overlays.
- Software: MAX/MSP
- Parsing Sensor Data
- Computer Vision – Realtime visualization of the aura
- Musical Compositions – Samples + FM synthesis + AM synthesis
The Mapping
Aural Aura relies on a mapping between energy point (chakra), color, sound frequency and movement, to produce a synesthetic experience that physically manifests the invisible and inaudible nature of the aura. The mapping of color to sound is based on “Rainbow Resonance”, a project I developed in Spring 2008, which assigns sound frequencies to colors in an intelligible manner by transposing light wavelengths 40 octaves below their spectrum to match the audible spectrum of the electromagnetic field. Aural Aura adds the element of movement to achieve an immersive synaesthetic experience.
The Moves
When the 8 shaolin moves are performed the chakra centers are activated allowing for a connectedness between body, mind and spirit, that enables a “balancing” of the energies to occur.
Why a Performance?
Performance art is an unprecedented expressive experience. Inherent in its nature is the capacity to involve the audience so that they in turn may become a part of the performance. Interactive art is a performative art that invites the audience to not only participate but in essence create the art. In this performance the dancer is not merely interpreting an aural event, but “invents” the soundscape through the dance. Through a tight mapping between color, sound and movement that allows a connectedness between body, mind and spirit, Aural Aura seeks to transcend the performer, and ultimately the audience into a “healing” experience.
Healing
The healing element of Aural Aura is implicit. The performance seeks a balancing of the energies of the body, through an alignment of the chakras using sound vibrations in conjunction with the corresponding colors, as chi kung movements activate the chakra centers.
The Future
Aural Aura can be expanded to integrate movement in three dimensional space through a mapping of the physical location in which the performance takes place. Sensors that measure parameters such as distance, vibration and force, can be coupled with multiple motion tracking cameras to enrich the performance. Furthermore, a performance could include a group of dancers who in an ideal user scenario compose symphonies through their dance, using a combination of wearable sensors, and tracking movement in 3D space through computer vision and sensors placed on location.
Inspiration
Aural Aura is a natural development of my previous project Rainbow Resonance which acted as a computer vision musical instrument. In this project the idea of producing sound through dance is further explored as the performer generates sound intervals through a mapping of her movements. The content of this project sprang from the desire to visualize the aura that extends from the physical human body, and to sonify the associated colors, using a mapping based on mathematics.
Symbolisms in Aural Aura
- Star tetrahedron
The metaphysical nature of numbers as they interact to construct the shapes of the five pointed and six pointed star is an underlying theme conveyed through all aspects of this project. Attuned to the immaterial reality of sound and color, Aural Aura attempts to physically manifest the immaterial dimensions of being. 
Wearable Design
In designing the form of the astral body dress I was inspired by Issey Miyake’s designs extending from the body in unique flower forms, and also Philips Design Probe Skin Dresses. My intention was to illuminate the astral body dress “from within” so that I would achieve a “glowing effect” in the areas of the chakras. Miyake’s illuminated dresses and Hussein Chalayan’s video dresses served as an inspiration. Laurie Anderson, Pamela Z, Letitia Sonami, Luibo Borissov inspired me with the use of a wearable interface and sensors to produce sound and images. Arleen Schloss’s fibre obtic dress by Maurice Daniel designed in the mid 80s was also one of my influences.

Dance
The Taiwanese dance group Cloudgate who use tai chi in their performance Moonwater was one of the most important inspirations that drove me to implement Chi Kung as a dance in Aural Aura. A beautiful solo performance by Yang LiPing entitled Moon that uses Kung Fu moves in the dance was another of my inspirations in designing Aural Aura.

The Trickster – An Overview
A playful character performed by Khoi Bao Le (a young choreographer from Viet Nam in training at Martha Graham School of Contemporary Dance), unexpectedly triggers sounds from his own movement and costume details, while his image is projected on screen. Within a sound environment of pre-recorded electro-acoustic music by Elodie Lauten, the performer initiates with his movement a new layer of interactive sound samples in an improvisational framework programmed in MAX/MSP by Sofia Paraskeva. Elodie Lauten is a classical and experimental composer whose work has been presented by the Lincoln Center Festival, the New York City Opera, WNYC, The Kitchen, the Performing Garage, the Dance Theater Workshop, La Mama, the Soho Baroque Opera, Downtown Music Productions, AFMM, Interpretations, the SEM Ensemble, The Whitney Museum, and at the Paris Museum of Modern Art. Her current discography includes 27 titles to-date, on both independent and major labels. She has taught on the composition faculty at New York University. Web site: http://www.elodielauten.net.

Rainbow Resonance – An Overview
In Rainbow Resonance the audience is encouraged to participate in a playful performance that engages the body to produce colorful images and sound resonances through simple movements. Anyone can potentially create a personal experience within the installation. The color scheme is based on the visible light spectrum and is also inspired by the chakras. A video camera is used as a sensor to detect motion, and motion tracking software technology is used to map the vertical and horizontal “zones” of movement in the space. The “zone” with the most vivid motion determines the predominant sound generated by the participant. This piece was shown at the Interactive Telecommunications Program Spring Show 2008 at NYU and was exhibited at the New York Hall of Science in October 2008 and February – April 2009.
