In this paper, we present a robust method to tackle the ambiguities in 3D arm tracking, especially those introduced by depth change (distance of the arm from the camera), and arm rotation about humerus (upper arm bone...

This paper describes an approach to tracking the global locations of multiple dancers using marker-based motion capture system from only unlabeled 3D marker data for the application of interactive dance. This algorithm is based on the fact that in the presence of multiple people, marker labeling is poor or even infeasible, while reconstruction of the marker 3D coordinates is still reasonable. The tracking of dancers is done through treating dancers with markers as point clouds that have noticeable characteristics. Such characteristics include fixed marker set, all the markers being within an average wingspan, and that the markers on a dancer are closely bounded together. Using these characteristics, a blurring process was used to find the location of the dancers, and a mean shift algorithm was implemented to track them. Satisfactory results have been obtained using the proposed method.

Effectively teaching introductory media signal processing (MSP) to students requires a means of communicating complex concepts without advanced mathematics. At the mediaarts and technologyprogram at UCSB we are teaching graduate mediaarts students concepts of MSP. These students, while interested in learning how their digital tools work, have an incredibly tough time working through the material the way traditional engineering students do. To address this we have used MATLAB to build a comprehensive suite of exploratory demonstrations and applications tailored to illustrate sophisticated concepts, and to inspire students that may not possess a strong background in mathematics. Our application, "Signals and Systems using MATLAB" (SSUM), is presented here, and its use in a course designed to teach MSP to mediaarts students is discussed. Its usefulness extends beyond mediaarts to engineering and computer science curriculum. SSUM can be obtained for free from http://***/***
