This paper investigates to what extent breathing can be used as a cue to turn-taking behaviour. The paper improves on existing accounts by considering all possible transitions between speaker states (silent, speaking, backchanneling) and by not relying on global speaker models. Instead, all features (including breathing range and resting expiratory level) are estimated in an incremental fashion...

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 month's installment of Generally Physiological takes a translational turn, discussing functional analyses of two proteins whose mutation is associated with disease (heart failure and cystic fibrosis, respectively) and the mechanism underlying the painful response to cold found in ciguatera. A tunable brake on cardiac contractility Cardiac contraction, like that of skeletal muscle, depends ...

This paper investigates gaze patterns in turn-taking. We focus on differences between speaker changes resulting in silences and overlaps. We also investigate gaze patterns around backchannels and around silences not involving speaker changes.

This paper explores the role of gaze in coordinating turn-taking in mixed-initiative conversation and specifically how gaze indicators might be usefully modeled in computational dialogue systems. We analyzed about 20 minutes of videotape of eight dialogues by four pairs of subjects performing a simple face-to-face cooperative laboratory task. We extend previous studies by explicating gaze patte...
