Mood contagion of robot body language in human robot interaction

The aim of our work is to design bodily mood expressions of humanoid robots for interactive settings that can be recognized by users and have (positive) effects on people who interact with the robots. To this end, we develop a parameterized behavior model for humanoid robots to express mood through body language. Different settings of the...

Robot Mood is Contagious: Effects of Robot Body Language in the Imitation Game

Mood contagion is an automatic mechanism that induces a congruent mood state by means of the observation of another person's emotional expression. In this paper, we address the question whether robot mood displayed during an imitation game can (a) be recognized by participants and (b) produce contagion effects. Robot mood was displayed by...

Joy, Distress, Hope, and Fear in Reinforcement Learning (Extended Abstract)

In this paper we present a mapping between joy, distress, hope and fear, and Reinforcement Learning primitives. Joy / distress is a signal that is derived from the RL update signal, while hope/fear is derived from the utility of the current state. Agent-based simulation experiments replicate psychological and behavioral dynamics of emotion...

Goal-Based Explainable Security Certificate Requests

In crisis situations it is important that crisis response workers can quickly get access to the right information for the tasks they are required to undertake. A distinction can be made between getting the right information and having the rights to get that information. The first is an information filtering and relevance problem, the second is a...

Designing interfaces for explicit preference elicitation: A user-centered investigation of preference representation and elicitation process

Two problemsmay arisewhen an intelligent (recommender) system elicits users’ preferences. First, theremay be amismatch between the quantitative preference representations in most preference models and the users’ mental preference models. Giving exact numbers, e.g., such as “I like 30 days of vacation 2.5 times better than 28 days” is difficult...

Eye Movements Disclose Decisions in Set

During the past several decades, much research has been done in the field of visual attention and cognitive processing, i.e., how does the human brain process visual stimuli. We show that the card game SET is a good candidate for investigating the relation between top-down versus bottom-up visual information processing. Further, we show that...
