Recognizing conversational context in group interaction using privacy-sensitive mobile sensors

Daniel Gatica-Perez, Dinesh Babu Jayagopi

The availability of mobile sociometric sensors allows Computer-Supported Cooperative Work (CSCW) designers the possibility to enhance online meeting support through automatic recognition of conversational context. This paper addresses the task of discrimin ...

Mining group nonverbal conversational patterns using probabilistic topic models

Daniel Gatica-Perez, Dinesh Babu Jayagopi

The automatic discovery of group conversational behavior is a relevant problem in social computing. In this paper, we present an approach to address this problem by defining a novel group descriptor called bag of group-nonverbal-patterns defined on brief o ...

This paper addresses the problem of discovering conversa- tional group dynamics from nonverbal cues extracted from thin-slices of interaction. We first propose and analyze a novel thin-slice interaction descriptor - a bag of group non- verbal patterns - wh ...

Predicting Remote Versus Collocated Group Interactions using Nonverbal Cues

Daniel Gatica-Perez, Dinesh Babu Jayagopi, Dairazalia Sanchez Cortes

This paper addresses two problems: Firstly, the problem of classifying remote and collocated small-group working meet- ings, and secondly, the problem of identifying the remote participant, using in both cases nonverbal behavioral cues. Such classifiers ca ...

Investigating Automatic Dominance Estimation in Groups From Visual Attention and Speaking Activity

Daniel Gatica-Perez, Jean-Marc Odobez, Silèye Oumar Ba, Dinesh Babu Jayagopi

We study the automation of the visual dominance ratio (VDR); a classic measure of displayed dominance in social psychology literature, which combines both gaze and speaking activity cues. The VDR is modified to estimate dominance in multi-party group discu ...

Predicting the Dominant Clique in Meetings through Fusion of Nonverbal Cues

Daniel Gatica-Perez, Dinesh Babu Jayagopi

This paper addresses the problem of automatically predicting the dominant clique (i.e., the set of K-dominant people) in face-to-face small group meetings recorded by multiple audio and video sensors. For this goal, we present a framework that integrates a ...
