Interpersonal relations are fickle, with close friendships often dissolving into enmity. In this work, we explore linguistic cues that presage such transitions by studying dyadic interactions in an online strategy game where players form alliances and break those alliances through betrayal. We characterize friendships that are unlikely to last and examine temporal patterns that foretell betraya...

We pair session types and contracts using two encodings. The encoding of session types accommodates width and depth subtyping, two properties that partially hold in contracts. The encoding of contracts accommodates complex synchronization patterns, since session types own a simple control protocol. The encodings allow one to use the two formalisms interchangeably, within the context of dyadic i...

In this paper we introduce an empirical study of multimodal cues of turn-taking dynamics in a social interaction context. We first identify pauses, gaps and overlapped speech segments in the dyadic conversation dataset. Second, we define two types of measurements, Mean Equalized Energy (MEE) and Animation Level (AL) on the audio and video channels, respectively. Then, we verify the hypothesis t...

The OFAI Multimodal Task Description Corpus (OFAI-MMTD Corpus) is a collection of dyadic teacher-learner (human-human and human-robot) interactions. The corpus is multimodal and tracks the communication signals exchanged between interlocutors in task-oriented scenarios including speech, gaze and gestures. The focus of interest lies on the communicative signals conveyed by the teacher and which ...

A recent trend in dyadic interaction research utilizes multiple modalities to better understand phenomena encompassing behavior matching (e.g., synchrony, alignment). Concurrent research has focused on a complementary framework of interaction, assessing the matching of power law distributions of behavior across two people: complexity matching. While both frameworks provide useful insights into ...

This study attempted to compare the relative frequency of the occurrence of Language Related Episodes (LREs) in the dyadic talks of pairs who were homogeneous and heterogeneous in terms of English proficiency.  LREs are those parts of the conversations where the interlocutors explicitly focus on linguistic form. The study was carried out with 60 Iranian university students of teaching English a...

Recent technologies enable the exploitation of full body expressions in applications such as interactive arts but are still limited in terms of dyadic subtle interaction patterns. Our project aims at full body expressive interactions between a user and an autonomous virtual agent. The currently available databases do not contain full body expressivity and interaction patterns via avatars. In th...

The development of e-interactions (IT supported business interaction) need to be facilitated by comprehensive frameworks for business interaction. Existing frameworks cover fragments of the important constituents of business interaction. Based on a review of existing frameworks a more comprehensive one is presented in this paper. This comprehensive framework builds upon a symmetric focus on a s...
