Linking science, art and practice through digital sound

Jennifer Burg

The science of sound and the creation of music provide a back drop for a discussion about new ways to instruct and inform computer scientists.

Techniques for motion data capture and analysis using thermal imaging and high- speed videography

Nickolay Hristov

Motion capture and analysis capabilities at CDI are emerging to include high-resolution, high-speed, and real-time data acquisition systems for application in art, science, medicine and education.Motion capture is the process by which movement is recorded and analyzed for further use via digital media. Rooted in traditional animation techniques such as rotoscoping, researchers originally developed motion capture for military and scientific applications. Nowadays a multitude of techniques under the category of motion capture are used in music and dance performance, athletics, sign language, gesture recognition, rehabilitation and medicine, biomechanics, special effects for live-action films, computer animation, engineering and ergonomics.Specific techniques vary depending on the application, but in general we can capture movement through the placement of sensors or markers on a moving subject. Software records the angles, velocities, accelerations and impulses of relevant components, providing an accurate digital representation of the movement. When translated sensitively, the data can result in spectacular dynamic imagery.
