Title: Movement sonification for body perception
Abstract:
Recently the body of work in interactive sonification has made the compelling argument that understanding how to sonify the characteristics of movement is important and can alter one’s own perception (Knudsen et. al., 2017, Frid et. al., 2018). The characteristics of movements can be classified into two types according to their dynamics and qualities. Movement dynamics are the most commonly used characteristics and are related to the shape and trajectory of the movement, including examples like position, size, acceleration, and direction. In contrast, movement qualities refer to movement’s temporal and expressive aspects, including fluidity, contraction index, force, and velocity.
In this seminar, I will be presenting a case study where we explored the use of dynamics-based sonification to alter body and flexibility perception during yoga practice. Additionally, I will discuss the development of a movement-tracking algorithm designed to detect movement qualities during dance practice, with the aim of identifying abnormalities in movement behavior that may indicate concerns related to body image.
Bio
Concepcion Valdez is a 2nd-year Ph.D. Student at the Ensenada Center for Scientific Research and Higher Education (CICESE) in México. She is part of the Veritas Research Lab, and her advisors are Dr. Mónica Tentori and Dr. Ana Tajadura-Jiménez. Concepcion’s research focuses on the development of Movement Sonification interfaces to change body self-perception. She evaluates how sound parameters can “trick the brain” into changing body image concerns and perceptions.
