Beyond Physical Gesture: The Search for Human Bandwidth
The paper discusses an innovative theory detailing how musicians will interface with modern digital performance technologies in the future and how this will radically alter the performing arts. The theory discusses technical, philosophical, and aesthetic issues associated with the evolution of performance technology and suggests that participation in the performing arts will soon include non-physical interfaces. While the paper investigates interface issues in the performing arts, the discussion is relevant to a variety of applications in which physical gesture plays an important role. By capturing and analyzing the subtle electrical signals sent to the muscles from the brain, it is possible to predict a performer’s physical intention prior to the actual movement of the muscles. The theory proposes that once the electrical signals have been sent from the brain they can be intercepted and interpreted by sophisticated algorithms and digital music technologies. The actual physical gesture may no longer be required to accomplish many performance tasks. Reducing a performer’s dependency on physical gesture is a radically new approach to the performing arts. The reduction of physical gesture will result in an increase in human bandwidth through the reorganization, reparsing, and more parsimonious organization of the brain’s finite processing resources.
