We present and describe CIF-CK — a social agent architecture that models reasoning about persistent social interactions to improve narrative engagement and play experience for human interactors. The architecture is inspired by McCoy et al’s Comme il-Faut (CiF) architecture that represented rich social interactions between agents that included feelings, social and relationship contexts, and long...

This paper describes a probabilistic syntactic approach to the detection and recognition of temporally extended activities and interactions between multiple agents. A complete system consisting of an adaptive tracker, an event generator, and the parser performs segmentation and labeling of a surveillance video of a parking lot; the system correctly identifies activities such as pick-up and drop...

To reveal the neural and behavioral dynamics of social interaction, single-person studies are increasingly complemented by research designs that simultaneously assess two or more interacting individuals. In this article, we review studies on neural mechanisms and markers of social interactions that use multi-person functional magnetic resonance imaging and electrophysiological recordings. We pr...

In the human behavior analysis, the Visual Focus Of Attention (VFOA) of a person is a very important cue. Its detection is difficult, though, especially in a unconstrained and crowded environment, typical of video surveillance scenarios. In this paper, we estimate the VFOA by defining the Subjective View Frustum, which approximates the visual field of a person in a 3D representation of the scen...

BACKGROUND The increasing number of opportunities for human-robot interactions in various settings, from industry through home use to rehabilitation, creates a need to understand how to best personalize human-robot interactions to fit both the user and the task at hand. In the current experiment, we explored a human-robot collaborative task of joint movement, in the context of an interactive ga...

Measuring brain activity simultaneously from two people interacting is intuitively appealing if one is interested in putative neural markers of social interaction. However, given the complex nature of interactions, it has proven difficult to carry out two-person brain imaging experiments in a methodologically feasible and conceptually relevant way. Only a small number of recent studies have put...

Abstract An essential tenet of social capital is that it a reciprocal process: networks produce desirable outcomes, and the resulting outcomes can then feed back into influencing networks. The current study among first to examine dynamic, process capital, using within-person measures from 2,065 reports offline online daily interactions 66 participants over 1-week period. Results show interactio...

This research-in-progress paper investigates the role of IS in delivering co-created services within the Financial Services Industry. These types of collaborative interactions where services are co-created between service providers and customers are under-researched, yet they are a growing phenomenon within professional services organisations. In particular, little is known about how IS can be ...

The 1976 outbreak of Legionnaires' disease led to the discovery of the intracellular bacterial pathogen Legionella pneumophila. Given their impact on human health, Legionella species and the mechanisms responsible for their replication within host cells are often studied in alveolar macrophages, the primary human cell type associated with disease. Despite the potential severity of individual ca...

Virtual worlds are developing rapidly over the Internet. They are visited by avatars and staffed with Embodied Conversational Agents (ECAs). An avatar is a representation of a physical person. Each person controls one or several avatars and usually receives feedback from the virtual world on an audio-visual display. Ideally, all senses should be used to feel fully embedded in a virtual world. S...
