	abstract = {The structure of the thesis is as follows: Chapter 2 presents an overview of the current approaches in segmentation and recognition of interaction. We present the relevant concepts and terminology, fields of application, major challenges and solution strategies, which provides the basis for our choice of relevant algorithms. In Chapter 3 we describe the data acquisition and the experimental scenario. Within this chapter we give a detailed description of the hardware devices, the recorded data, and the acquisition of the ground truth used for evaluation of experimental results for both, segmentation and classification. Finally, we give an overview of the data characteristics for all modalities, motivating our approach to modeling and segmentation. Chapter 4 is dedicated to the theoretical background of the segmentation framework. The first Section 4.1 introduces the Bayesian segmentation framework by P. Fearnhead. Integrated into this framework is our choice of models, suitable for detection of structural changes in the recorded data (described in Section 4.2). In the last Section 4.3 we present our two approaches to multimodal segmentation: the hierarchical and the parallel approach. Chapter 5 describes and compares experimental results for unimodal, bimodal, and multimodal segmentation. Furthermore, it presents quantitative evaluations of the influence of central parameters on the segmentation. Chapter 6 is dedicated to an approach towards higher-level representation. The first two sections of this chapter present the theoretical background of the unsupervised classification approach (Sections 6.1 and 6.2). Furthermore, Section 6.4 presents experimental results. The influence of different modalities on the results of clustering is investigated. Parts of the Chapters 3-6 are based on earlier publications. We conclude this work and discuss its possible implications in Chapter 7.},
