We address the problem of categorizing turn-taking interactions between individuals. Social interactions are characterized by turn-taking and arise frequently in real-world videos. Our approach is based on the use of temporal causal analysis to decompose a space-time visual word representation of video into co-occuring independent segments, called causal sets [1]. These causal sets then serves ...

This paper provides an extensive overview of existing research in the field of categorizing software applications. This research is compared and discussed based on a number of different criteria: the categorization attributes that are supported, the specific techniques and algorithms that are used for supporting these attribute based categorization; the types of software artifacts that are bein...

Augmented Reality (AR) superimposes virtual information onto the real world. AR system development is reaching the maturity of Virtual Reality (VR) systems. However, AR systems vary considerably due to the variety of applications that use different input and output methods. There is therefore a need to categorize these systems in order to ascertain the options available in the use of AR for par...
