I developed Vital Threads Biofeedback Apparel to open design and fashion to dynamic new forms of self awareness, personal expression and interpersonal communication. Typically, we are all vastly limited in our expressive outlet to engage a collective awareness. By measuring and displaying the wearer's biological signals, Vital Threads Biofeedback Apparel gives the wearer the freedom to express his or her personal vantage on a moment by moment basis.

Vital Threads has been shown as wearable biofeedback art at a number of galleries, museums, conferences, and hackerspaces around the world, including the National Taiwan Museum of Fine Art, the World Maker Faire, among many other venues.

Truth Wristband

A wristband that dynamically reflects the wearer's psycho-emotional response to the world, promoting internal states to be externalized and made into interactive forms of expression. The device measures the galvanic skin response (a marker of emotional arousal commonly used in lie detector tests), measuring micro-changes in sweating on your hands. The device's lights turn from blue to red as the wearer becomes excited. Telling a lie may make you sweat, but ask the right question and the answer doesn't matter!

Below is a video of my brother, Ian, wearing the Truth Wristband while I ask him some questions to see what sorts of things get his Truth meter going. Note that it takes 1-2 seconds for the psychodynamic response to be expressed in the skin response.

Heart-felt Apparel

Wearables that detect
your heart beat and externalize it as pulses of light. Sensors read the wearer's EKG and produce flashes of light in time with his/her own heart. Wearing the shirt gives an intense feeling of life and rhythm, while at the same time reminding you of your electrical and mechanical roots. It's truly amazing how much the heart responds to social interaction and yet is almost entirely ignored as it meters our life.

Thinking Cap

A hat that measures the wearer's brain activity from the wearer's scalp EEG and projects changes in neuronal synchrony on modular light arrays. Highly focused attention increases the brain's beta and gamma oscillations and turns the frontal light modules red, while entering a meditative state produces large alpha rhythms and turns the rear light modules red.
