The role of emotion in self-explanations by cognitive agents

Artificial Intelligence (AI) systems, including intelligent agents, are becoming increasingly complex. Explainable AI (XAI) is the capability of these systems to explain their behaviour, in a for humans understandable manner. Cognitive agents, a type of intelligent agents, typically explain their actions with their beliefs and desires. However,...

Self-explanations of a cognitive agent by citing goals and emotions

This paper presents a cognitive (belief-desireintention based) agent that can self-explain its behaviour based on its goals and emotions. We implement a cognitive agent, embodied by a nao-robot or virtual avatar thereof, to play a quiz with its user. During the interaction the agent intelligently selects questions to optimally educate the user....

Effects of a robotic storyteller's moody gestures on storytelling perception

A parameterized behavior model was developed for robots to show mood during task execution. In this study, we applied the model to the coverbal gestures of a robotic storyteller. This study investigated whether parameterized mood expression can 1) show mood that is changing over time; 2) reinforce affect communication when other modalities exist...

A warm touch of affect?

One of the research areas within affective Computer Mediated Communication currently under investigation is that of mediated social touch. A social touch is a complex composition of different physical parameters that can be simulated by haptic technologies. In this article we argue why we think it makes sense to incorporate warmth - and in...

Warmth in affective mediated interaction: Exploring the effects of physical warmth on interpersonal warmth

Recent research suggests that physical warmth activates perceptions of metaphorical interpersonal warmth and closeness, and increases pro-social behavior. These effects are grounded in our earliest intimate experiences: being held by our loving caregivers. These findings provide reasons to incorporate warmth in devices for distant affective...

Design of a wearable research tool for warm mediated social touches

Social touches are essential in interpersonal communication, for instance to show affect. Despite this importance, mediated interpersonal communication oftentimes lacks the possibility to touch. A human touch is a complex composition of several physical qualities and parameters, but different haptic technologies allow us to isolate such...

Multi-modal affect induction for affective brain-computer interfaces

Reliable applications of affective brain-computer interfaces (aBCI) in realistic, multi-modal environments require a detailed understanding of the processes involved in emotions. To explore the modalityspecific nature of affective responses, we studied neurophysiological responses (i.e., EEG) of 24 participants during visual, auditory, and...
