Abstract: Technological innovations like physiological computing offer new possibilities when exploring audience-performer interaction. To avoid technological solutionism that often accompanies biosensor applications in performing art, an artistic interventions approach was used. This paper describes a recent art-science residency consisting of three artistic experiments: the audience’s electrodermal, activity-driven soundscape in a dance improvisation, a “lie detector” applied to the actor just after the performance, and a heart-rate-driven personal discotheque installation. Both artist and scientist provide reflections on future development of this transdisciplinary field from the performing art perspective.   Nüüdisaegne interaktiivne teater toetub tehnoloogilistele uuendustele ja järjest enam kasutatakse uusi tehnoloogiaid ka kunstiteose sisu loomisel: on need siis vaatajate reaktsioone tajuvad riided, voogteatri etendus või vaatajate neurofüsioloogilisi reaktsioone mõõtvad sensorid. Etenduskunstnik Taavet Jansen ja neuroteadlane Aleksander Väljamäe töötasid publiku ja esinejate füsioloogiliste reaktsioonidega kunstiteaduse residentuuris Tallinna Ülikoolis veebruarist 2019 kuni juunini 2019. Füsioloogilisi reaktsioone uuriti kolme kunstilise eksperimendi jooksul või järel ning see artikkel kirjeldabki neid eksperimente, kunstniku mõtisklusi oma uurimisreisist ja arutleb, kuidas selliseid interaktsioonivõimalusi saaks kasutada voogteatri platvormidel. Iga kirjeldatud eksperimendi kohta avaldavad autorid ka oma mõtteid ja teevad ettepanekuid, mida eksperimendi kordamisel võiks teha teistmoodi. Kunstilises eksperimendis „Neurokoreograafiline eksperiment nr 4“ kasutati interaktiivset lahendust, kus neljale vaatajale kinnitatud sensorid mõõtsid nende erutuse taset (electrodermal activity galvanic skin response) improvisatsioonilise tantsuetenduse vältel Tallinnas, Kanuti Gildi SAALis 06.06.2019. Vaatajate reaktsioone kasutati reaalajas helikujunduse manipuleerimisel. Selline interaktiivne lahendus tekitas kunstiliselt intrigeeriva tagasiside-efekti, kus vaatajate tahtmatud reaktsioonid hakkasid mõjutama kogu lavastuse tervikut. Vaatajad said tahtmatult endale „hääle“, mida said interpreteerida kõik osalised kogu terviku kontekstis. Kunstilises eksperimendis „Macbeth“ kasutati erutust mõõtvaid sensoreid, salvestamaks näitleja reaktsioone intervjuu ajal, kus esitati küsimusi tema rolliloome kohta etenduses, mis oli lõppenud 10 minutit enne intervjuu algust. Tegemist oli Alo Kõrve Macbethi rolliga Tallinna Linnateatri lavastuses „Macbeth“. Prokurör Steven-Hristo Evestuse läbi viidud intervjuu eesmärgiks oli mõista, milliseid tehnikaid kasutab näitleja oma rolli luues, ning tehnoloogiat kasutades analüüsida, kas näitleja on teadlik laval tehtud otsustest. Heli- ja valgusinstallatsioon „Heartrate Party“ põhines kontseptsioonil, kus külastaja südamerütm mõjutas kogu installatsiooni heli- ja valguskujunduse tempot. Südamerütmi mõõdeti spetsiaalse sensoriga ja kasutatud videokujundus nii instrueeris osalejaid kui ka andis tagasisidet õnnestumisest või ebaõnnestumisest. Installatsioon oli avatud Tallinnas, Kanuti Gildi SAALi keldrisaalis 05.–07.06.2020 ja seda külastas 20 vaatajat. aasta esimeses pooles, kui COVID-19 pandeemia põhjustas eriolukorra kogu maailmas, ei tohtinud teatrid ja etendusasutused avalikke üritusi korraldada. Teatrid hakkasid oma etendusi andma voogedastust võimaldavatel platvormidel. Kuna voogteater avab etenduste mängimiseks palju uusi võimalusi, siis me analüüsime residentuuris kasutatud kontseptsioone ka voogteatri perspektiivist. Kõiki eelpool mainitud kontseptsioone oleks võimalik osaliselt kanda üle ka veebikeskkonda, kuid need eeldavad kasutajapoolset tehnoloogilist valmisolekut. Sensortehnoloogiad võimaldavad voogteatri etenduste vaatajate reaktsioone ja käitumist analüüsida ja salvestada. Kuna nende tehnoloogiate kasutus sellises kontekstis on veel uus, siis küsimused, mis puudutavad eetikat ja isikuandmeid, vajavad alles väljatöötamist. Kokkuvõttes väidame, et väga palju uurimistööd on alles ees ja meetodid, kuidas interpreteerida esinejatelt ja vaatajatelt kogutud andmeid, on alles vaja välja töötada. Tihti kasutatakse andmeid interaktsiooni eesmärgil pigem otseseid tõlgendusi luues – biosignaalide numbriline väärtus tõlgitakse otse mõneks audiovisuaalses kujunduses oluliseks väärtuseks. Selline tõlgendus annab küll laval toimuvale perfektse sünkrooni, kuid vastust jääb ootama oluline küsimus, mida need andmed väljendavad, mida nad tähendavad. Kunstis jääb tihti puudu teoreetilistest teadmistest, mis aitaksid intuitiivselt tehtud kunstilisi otsuseid raamistada. Selline teadmiste ülekandmine kunsti ja teaduse vahel avaks uusi võimalusi kunstiteoste interpreteerimisel, aga ka teaduse rikastamisel.

Background: Blood vessels in body respond to sympathetic upsurge and, occlusion of blood vessels supplying vital organs excites autonomic reactions, building up chaos in homeostasis. Autonomic response to occlusion of major artery, not supplying to vital organs, remains least explored in the medical literature. Thus we have observed, in vivo, undulating autonomic response to heart beat and galvanic skin response for transient occlusion of left brachial artery, in this study. Methods: Occlusion of brachial artery was maintained approximately 10mmHg above the systolic pressure by mercury manometer with cuff inflated at two inches above the cubital fossa of left hand. Heart rate and skin conductance was picked up by the transducers placed at appropriate locations on body surface in 40 subjects. Results: Paired t test, repeated measures ANOVA and Pearson correlation are utilized to compare the recorded variables. Heart rate is significantly decreased (p=0.000) and amplitude of galvanic skin response is significantly increased (p=0.000) in all subjects for induced occlusion of brachial artery in left arm. ANOVA compared among levels of pre-occlusion, occlusion and post-occlusion is significant for heart rate (p=0.000). Pearson correlation between GSR and heart rate is weakly inverse (r = -0.028). Conclusions: Episodic occlusion of artery does excite the autonomic reactions in healthy young adults. Simultaneous rise in parasympathetic and sympathetic response is an obligatory autonomic response for the brief occlusion of left brachial artery.

The Relationship

Addressing the emotional and mental health of the bedridden elderly is necessary as they are more likely to be depressed being isolated and dependent on a caregiver for a prolonged time. Several studies have been carried out to identify the mental stress of patients through their skin conductivity. The variations in the sympathetic nervous system reflect the emotional state of a person. This is demonstrated by the Galvanic Skin Response and thus can be used as a denotation of psychological or physiological arousal. Such arousal causes the blood capillary dilation, increment of sweat gland activities making the skin further conductive to electricity. In this study we develop a sensor module composed of a Galvanic Skin Response sensor for the bed ridden elderly and identify the relationship between body temperature, heart rate and GSR of them. The experiment is conducted upon 10 bed ridden elderly aged from 60 – 80 years of the Mihinthale region. The observations demonstrate a correlation between the heart rate, body temperature, skin conductivity and the human physiological states.

Loot boxes in video games have blurred the lines between gaming and gambling. Research suggests the thrill from gambling comes from associated increases in physiological arousal not possible monetary gains. Gamers performing microtransactions to purchase loot boxes can lead to similar increases in physiological arousal. However, problematic gamblers no longer receive increases in arousal and become hyposensitive to reward. This hyposensitivity may also be present in problematic gamers. Twenty-five adult male participants took part in the within-participant design experiment measuring heart rate (HR) and galvanic skin response (GSR) while they were gaming and performing a microtransaction. GSR increased from baseline. HR decreased while performing a microtransaction. There was a negative correlation between gaming addiction scores and participants’ physiological arousal. The increases in arousal suggest microtransactions in gaming could potentially lead to problematic levels of use, while hyposensitivity could explain the higher gaming addiction relating to lower arousal during gameplay.

Wearable sensors are increasingly used in research, as well as for personal and private purposes. A variety of scientific studies are based on physiological measurements from such rather low-cost wearables. That said, how accurate are such measurements compared to measurements from well-calibrated, high-quality laboratory equipment used in psychological and medical research? The answer to this question, undoubtedly impacts the reliability of a study’s results. In this paper, we demonstrate an approach to quantify the accuracy of low-cost wearables in comparison to high-quality laboratory sensors. We therefore developed a benchmark framework for physiological sensors that covers the entire workflow from sensor data acquisition to the computation and interpretation of diverse correlation and similarity metrics. We evaluated this framework based on a study with 18 participants. Each participant was equipped with one high-quality laboratory sensor and two wearables. These three sensors simultaneously measured the physiological parameters such as heart rate and galvanic skin response, while the participant was cycling on an ergometer following a predefined routine. The results of our benchmarking show that cardiovascular parameters (heart rate, inter-beat interval, heart rate variability) yield very high correlations and similarities. Measurement of galvanic skin response, which is a more delicate undertaking, resulted in lower, but still reasonable correlations and similarities. We conclude that the benchmarked wearables provide physiological measurements such as heart rate and inter-beat interval with an accuracy close to that of the professional high-end sensor, but the accuracy varies more for other parameters, such as galvanic skin response.

The purpose of this study was to compare changes in autonomic responses due to different driving and road conditions. We measured physiological responses of the 10 health subjects such as Heart Rate Variability (HRV), Galvanic Skin Response (GSR) and skin temperature in rest and stimulation conditions. The ratio of LF/HF significantly increased and averaged R-R interval decreased on the abrupt stopping and starting and abruptly curved road conditions, compared to other conditions. Mean value of GSR increased and mean value of skin temperature decreased in the abrupt stopping and starting and abruptly curved road conditions, compared to other conditions.

Emotion is the excited mental state of a person caused by internal and external factors. In this work, a person’s physiological parameters are measured to decide emotional status. A generalized system measures changes occurring in the body of a subject, such as heart rate, blood pressure, respiratory rate, electro-dermal (Galvanic skin resistance) activity, and arm and leg motions. These measurements are then compared with the normal levels of the subject. The present work monitors the physiological parameters by connecting sensors at specific points on a test body. Two physiological parameters are considered: galvanic skin response (GSR) and finger tip temperature (FTT). The heart rate is predominant in deciding the emotion of a person. This system, in conjunction with a certified examiner, is used to analyze a subject’s stress. A system is constructed that measures physiological parameters along with signal conditioning units. These measurements are transmitted to a LabVIEW add-on card for further data processing and analysis. LabVIEW is a graphical programming language that includes all tools necessary for data acquisition, data analysis, and presentation of results. The results obtained are realistic and provide a measure of accuracy.

Putting is paramount to performance in golf and differentiates low and high achievers in the sport. In the present study, we compared the heart rate, respiration rate, and galvanic skin response for missed and holed putts performed by 13 skilled male golfers from a 12-ft (3.65-m) distance. Contrary to our expectations, no significant effects were observed for heart rate and respiration rate, likely because skilled athletes (a) engage in preperformance routines and are able to control their breathing rhythms, which in turn influence their heart rate; and (b) physiological responses are idiosyncratic, akin to the Individual Zones of Optimal Functioning framework. Congruent with our expectations, we observed a significant effect for galvanic skin response, with higher values observed for missed putts. This effect was robust to individual differences and suggests that biofeedback interventions aimed at enhancing awareness of autonomous physiological responses can be beneficial for performance enhancement in golf putting.
