Performance, Art, and Cyber-Interoceptive System

PACIS Pak (2019) and PACIS2 (2021) by M.D. Hosale and A. Macy

PACIS (Performance and Art Cyber-Interoceptive System) is a modular wearable wireless device solution for full spectrum biosensing* for use in the maker and arts communities.  Data acquisition happens via the Biopac MP40 (  The basis of the technology is a set of signal processing software tools for the analysis of real-time biophysical signals while transmitting the data it is collecting and analyzing wirelessly. The advantage is that the entire analysis system is encapsulated into a set of wearable components, making it much cheaper and less cumbersome to implement in interactive art and performance contexts than in similar systems. The system can be readily combined with additional hardware providing the capability of mapping biophysical signals to experiential, audio/visual media. The tools behind this technology are deployable on many platforms, including software tools that artists and others who are interested in the sonification, visualization, and translation of biophysical data to other media for deployment in performances, installations, and mixed reality environments.

* This includes: electrocardiogram (ECG), electromyogram (EMG), electroencephalogram (EEG), electrooculogram (EOG),  electrogastrogram (EGG), ventilatory effort (RSP Effort), electrodermal activity (EDA), pulse plethysmogram (PPG), blood pressure (BP), and blood flow.

Projects Realized with PACIS technology:


Anouk Wipprecht

2021, PACIS Pak was used in making: HeartBeatDress - Anouk Wipprecht x Swarovski || 'Wearable Emotions' from Anouk Wipprecht on Vimeo.

In collaboration with a leading crystal manufacturer, Dutch FashionTech Designer Anouk Wipprecht releases her new 3D printed 'HeartBeatDress' – a dress that records and broadcasts something very 'intimate' to you as a provocation to be true to your feelings.

“At the dawn of this Modern Age, technology has given us the flexibility to investigate endless opportunities with electronics that have become smaller and smaller. Over the past 20 years, I've been connecting our bodies to electronics and integrate this through robotic fashion design. What does it mean when we can connect technological-expressive garments to our bodies, body signals, and even emotions?” the designer questions.

Reaching farther than curiosity, Dutch designer Anouk Wipprecht's creations combine haute couture aesthetics with digital technology that examines the behavioral, neurological, and emotional states through visceral interaction. With a forward-thinking vision, she believes high-tech fashion is the key to a deeper understanding of how we process our emotions and their effects on our minds and bodies.

One of her new deviously disruptive designs is a piece she's developed with crystal-maker Swarovski that uses built-in sensors, robotics, sound and light to respond in time with the wearer’s heartbeat. (


the body in\verse

Currents 2021 (Virtual) Livestream multimedia performance. June 19th, 2021

The body in\verse is an online, interactive performance that combines biophysical sensing, emotive state sonification and visualization, and generative poetry to create the scene. The performance provides a deep dive from the world outside of ourselves, that is dissociated by mediated technology, into the interoceptive abyss of our emotive sea. A biophysical sensing system measures the emotional affect of the performer, and then uses that data to drive the sound, abstract imagery, and a generative poetry algorithm. Emotional affect of the performer is assessed through arousal and valence measures derived from correlation of the performer’s heart rate and heart rate variability. An algorithm generates poetry using conversations that take place with the audience as source material. The poetry source material is then algorithmically organized according to its sentiment (positive to negative), and mapped to the emotional affect of the performer driven by the emotional affect assessment from her biophysical measures.

Hand to Heart

Alan Macy

The base system is built around the Hand to Heart (

By transporting a “mimic” of the heart, outside of a participant’s body, another person can touch this very central part of the participant’s nature. In the case of “Hand to Heart”, the embodiment principle is mediated by the senses of sight, sound and touch, so the recipient participant is gifted an intimate, physical connection to the source participant.

The “Hand to Heart” project establishes a vulnerability for the participants. The two participants, source and recipient, establish a direct link between their sensory frameworks.

The source participant develops a visceral awareness of the environment’s effect upon their own physiological state and then, by extension, their conscious state.

The idea of the heart “mimic” is central to this art project because the heart has deep and abiding connections to the emotional and motivational foundational states that support judgement.

The external heart “mimic” is solidly based in robust technology. The technology amplifies the electrocardiogram (ECG) of the source participant by a rough factor of 2000. This amplified data drives light sources, audio and tactile transducers inside the heart “mimic”. The ECG is representative of the contraction of cardiac muscle, so this same contraction signal drives the activation behavior of the heart “mimic”. The link between the real heart, and the heart “mimic”, is essentially instantaneous and fully analog.

Mark-David Hosale
Mark-David Hosale (, is a computational artist and composer who has given lectures and taught internationally at institutions in Denmark, The Netherlands, Norway, Canada, and the United States. He is an Associate Professor in Computational Arts in the School of the Arts, Media, Performance, and Design, Toronto, Ontario, Canada. His solo and collaborative work has been exhibited internationally at such venues as the SIGGRAPH Art Gallery (2005), International Symposium on Electronic Art (ISEA2006), BlikOpener Festival, Delft, The Netherlands (2010), the Dutch Electronic Art Festival (DEAF2012), Biennale of Sidney (2012), Toronto’s Nuit Blanche (2012), Art Souterrain, Montréal (2013), and a Collateral event at the Venice Biennale (2015), Currents New Media (2017), among others. Mark-David’s work explores the boundaries between the virtual and the physical world. His practice is varied, spanning from performance (music and theatre) to public and gallery-based art. His interdisciplinary practice is often built on collaborations with architects, scientists, and other artists.
