    AffecTech-an affect-aware interactive AV Artwork
    Coghlan, Niall; Jaimovich, Javier; Knapp, R. Benjamin; O’Brien, Donal; Ortiz, Miguel A. (ISEA International, 2009)
    New developments in real-time computing and body-worn sensor technology allow us to explore not just visible gestures using inertial sensors, but also invisible changes in an individual’s physiological state using bio-sensors (Kim & André 2008). This creates an opportunity for a more intimate interaction between the observer and technology-based art (Gonsalves 2008). We present a technical overview of the AffecTech system; a bio-signal based interactive audiovisual installation commissioned as part of the pre-ISEA symposium in November 2008. Observers were invited to sit on one of 2 sensor-enhanced chairs (Coghlan & Knapp 2008), which transmitted physiological data about the occupant to a central control system. This data was used to control and modulate interactive visuals, live video feeds and a surround sound score, with events and interactions dependent on the observers’ affective/emotional state and the disparity or similarity between the bio-signals of the chairs occupants. This technical overview is followed by an examination of the outcomes of the project, from both the artistic and technical viewpoints, with recommendations for modification in future implementations.

    Biosignal-driven Art: Beyond biofeedback
    Ortiz, Miguel A.; Coghlan, Niall; Jaimovich, Javier; Knapp, R. Benjamin (CMMAS, 2011)
    Biosignal monitoring in interactive arts, although present for over forty years, remains a relatively little known field of research within the artistic community as compared to other sensing technologies. Since the early 1960s, an ever-increasing number of artists have collaborated with neuroscientists, physicians and electrical engineers, in order to devise means that allow for the acquisition of the minuscule electrical potentials generated by the human body. This has enabled direct manifestations of human physiology to be incorporated into interactive artworks. This paper presents an introduction to this field of artistic practice and scientific research that uses human physiology as its main element. A brief introduction to the main concepts and history of biosignal-driven art is followed by a review of various artworks and scientific enquiry developed by the authors. This aims at giving a complete overview of the various strategies developed for biosignal-driven interactive art.

    The Emotion in Motion Experiment: Using an Interactive Installation as a Means for Understanding Emotional Response to Music
    Jaimovich, Javier; Ortiz, Miguel A.; Coghlan, Niall; Knapp, R. Benjamin (NIME, 2012)
    In order to further understand our emotional reaction to music, a museum-based installation was designed to collect physiological and self-report data from people listening to music. This demo will describe the technical implementation of this installation as a tool for collecting large samples of data in public spaces. The Emotion in Motion terminal is built upon a standard desktop computer running Max/MSP and using sensors that measure physiological indicators of emotion that are connected to an Arduino. The terminal has been installed in museums and galleries in Europe and the USA, helping create the largest database of physiology and self-report data while listening to music.
