(2016): Computational Analysis and Simulation of Empathic Behaviors. A Survey of Empathy Modeling with Behavioral Signal Processing Framework. In: Current psychiatry reports 18 (5). DOI: 10.1007/s11920-016-0682-5
DOI: https://doi.org/10.1007/s11920-016-0682-5 Abstract: Empathy is an important psychological process that facilitates human communication and interaction. Enhancement of empathy has profound significance in a range of applications. In this paper, we review emerging directions of research on computational analysis of empathy expression and perception as well as empathic interactions, including their simulation. We summarize the work on empathic expres- sion analysis by the targeted signal modalities (e.g., text, au- dio, and facial expressions). We categorize empathy simula- tion studies into theory-based emotion space modeling or application-driven user and context modeling. We summarize challenges in computational study of empathy including con- ceptual framing and understanding of empathy, data availability, appropriate use and validation of machine learn- ing techniques, and behavior signal processing. Finally, we propose a unified view of empathy computation and offer a series of open problems for future research.

(2015): Using Ethnography of Communication in Organizational Research. In: Organizational Research Methods 18 (4), S. 629-655. DOI: 10.1177/1094428115590662
DOI: https://doi.org/10.1177/1094428115590662 Abstract: Ethnography of Communication offers new analytical and interpretive possibilities for contextually sensitized, language- and communication-based ethnographic studies of management and organization. In this article we provide an introduction and overview of relevant linguistic and related fields, positioning Ethnography of Communication within the broader context of anthropology, ethnomethodology, and sociolinguistics. We describe Dell Hymes’s seminal contribution to theory and method of Ethnography of Communication (foregrounding Hymes’s signature concept of 'communicative competence') and outline what the application of an Ethnography of Communication approach in management research might entail (illustrating the application of Hymes’s SPEAKING grid). We conclude by offering an example of how the methods of Ethnography of Communication might be applied usefully to the study of organizational language, discourse, and communication.

(2014): Learning Compliant Manipulation through Kinesthetic and Tactile Human-Robot Interaction. In: IEEE Transactions on Haptics 7 (3), S. 367-380. DOI: 10.1109/TOH.2013.54
DOI: https://doi.org/10.1109/TOH.2013.54 Abstract: Robot Learning from Demonstration (RLfD) has been identified as a key element for making robots useful in daily lives. A wide range of techniques has been proposed for deriving a task model from a set of demonstrations of the task. Most previous works use learning to model the kinematics of the task, and for autonomous execution the robot then relies on a stiff position controller. While many tasks can and have been learned this way, there are tasks in which controlling the position alone is insufficient to achieve the goals of the task. These are typically tasks that involve contact or require a specific response to physical perturbations. The question of how to adjust the compliance to suit the need of the task has not yet been fully treated in Robot Learning from Demonstration. In this paper, we address this issue and present interfaces that allow a human teacher to indicate compliance variations by physically interacting with the robot during task execution. We validate our approach in two different experiments on the 7 DoF Barrett WAM and KUKA LWR robot manipulators. Furthermore, we conduct a user study to evaluate the usability of our approach from a non-roboticists perspective.
