La pratique artistique de Tanya Tagaq se caractérise par le recours à de nombreux effets vocaux, issus tant du katajjaq que d’autres traditions musicales, que la chanteuse semble coordonner à des mouvements et des gestes expressifs. L’hypothèse est que les mouvements du bras, des mains, du corps de Tagaq sur scène possèdent, tout comme les sons qu’elle produit, une dimension symbolique pertinente pour la performance et se coordonnent dans une même expression. Peut-on identifier une typologie de correspondances voix/gestes lors d’une performance de Tagaq? Pour explorer son geste musical en rapport avec la production du son, les données ont été générées par la captation des mouvements et de la voix lors de performances scéniques (LARC et Palais Montcalm, Québec, janvier-février 2016), à partir d’un système de motion capture (VICON), d’un microphone de gorge et d’un traitement informatique. On explorera ici un terrain symbolique, éclaté, souvent inaccessible car métaphorique, et peu foulé par la recherche, notamment du fait de la singularité de Tagaq qui intègre autant des éléments de sa culture inuit que ceux de la culture transnationale. Étant donné sa signification expressive pour l’auditoire, il s’agit de saisir ce que pourrait signifier ou exprimer le mouvement corporel en lien avec les émissions vocales de l’artiste.

Among the qualities that distinguish dance from other types of human behavior and interaction are the creation and breaking of synchrony and symmetry. The combination of symmetry and synchrony can provide complex interactions. For example, two dancers might make very different movements, slowing each time the other sped up: a mirror symmetry of velocity. Examining patterns of synchrony and symmetry can provide insight into both the artistic nature of the dance, and the nature of the perceptions and responses of the dancers. However, such complex symmetries are often difficult to quantify. This paper presents three methods – Generalized Local Linear Approximation, Time-lagged Autocorrelation, and Windowed Cross-correlation – for the exploration of symmetry and synchrony in motion-capture data as is it applied to dance and illustrate these with examples from a study of free-form dance. Combined, these techniques provide powerful tools for the examination of the structure of symmetry and synchrony in dance.

AbstractRecent epidemiological analyses in fencing have shown that injuries and pain linked specifically to fencing training/competition were evident in 92.8% of fencers. Specifically the prevalence of Achilles tendon pathology has increased substantially in recent years, and males have been identified as being at greater risk of Achilles tendon injury compared to their female counterparts. This study aimed to examine gender differences in Achilles tendon loading during the fencing lunge.Achilles tendon load was obtained from eight male and eight female club level epee fencers using a 3D motion capture system and force platform information as they completed simulated lunges. Independent t-tests were performed on the data to determine whether differences existed.The results show that males were associated with significantly greater Achilles tendon loading rates in comparison to females.This suggests that male fencers may be at greater risk from Achilles tendon pathology as a function of fencing training/ competition.

"Operative Ontologien werden in diesem Artikel als relationale kommunikative Situationen vorgestellt, in denen Medien und Technik Teil einer Praxis sind, aber nicht einfach mit dieser zusammenfallen. Die Ontologie bezieht sich auf eine temporäre Konstellation, beispielsweise eine Verknüpfung von Maschine, Körper und Bild, in der die ontologische Frage der Anthropologie perspektivisch immer wieder verschoben wird. Wie das genau zu verstehen ist, wird am Fallbeispiel der Motion-Capture-Technik deutlich, in der durch eine Verschmelzung von Live Action Movie und der animierten Welt der Visual Effects eine permanente Veränderung dessen erfolgt, was als Mensch oder menschliche Umwelt angesehen wird. This article presents operational ontologies as communicative situations in which media and technology are part of a practice, but do not simply coincide with it. Ontology refers to a temporary constellation, for example a link between machine, body and image, which shifts the ontological question of anthropology in perspective time and again. This thesis is further illustrated by a case study of the motion capture technique, whose merging of live action movie and the animated world of visual effects leads to a permanent modification of our notions of the human being and human environment.
