Conference Paper
This paper addresses how robots should communicate with humans so that the interaction is successful and satisfying for the user. Specifically, within the present study, nine different communication strategies were examined for a service robot that provides transportation of goods by semi-automated following. The communication style (humanlike frie...
Presentation
While humans actually need some overt communication channel to transmit information, be it verbally or non-verbally, robots could use their network connection to transmit information quickly to other robots. This raises the question how this covert robot-robot communication is perceived by humans. The current study (n = 183) investigates how transp...
Conference Paper
In this work, we provide an argument and first empirical insights that existing technology acceptance models fall short when it comes to explaining spontaneous, unplanned and unsolicited encounters between humans and delivery robots on the street. Since technology acceptance models have been defined by the technology's perceived ease of use, percei...

Full-text available
The research community of human-robot interaction relies on theories and phenomena from the social sciences in order to study and validate robotic developments in interaction. These studies mainly concerned one (human) on one (robot) interactions in the past. The present paper shifts the attention to groups and group dynamics and reviews relevant c...
Chapter
Based on the assumption that humans align linguistically to their interlocutor, the present research investigates if linguistic alignment towards an artificial tutor can enhance language skills and which factors might drive this effect. A 2 \(\times \) 2 between-subjects design study examined the effect of an artificial tutor’s embodiment (robot vs...

Full-text available
Human-robot encounters in public spaces represent diverse and complex social situations and will raise new demands for theoretical foundations and methods used in HRI. In an exploratory field study with covert observation in an urban public space using a mock-up of a delivery-robot in a wizard-oz-approach, we hope to gain insights into spontaneous...
Chapter
Social robots designed to live and work with humans will have to recognize, learn from, and adapt to multiple users, since humans live and organize themselves in groups. Social robots must consider the social dynamics that arise when humans interact in groups as well as the social consequences of their own behaviour in these groups. When trying to...

Article
Full-text available
Artificial agents are becoming prevalent across human life domains. However, the neural mechanisms underlying human responses to these new, artificial social partners remain unclear. The uncanny valley (UV) hypothesis predicts that humans prefer anthropomorphic agents but reject them if they become too humanlike-the so-called UV reaction. Using fMR...
Conference Paper
Artificial entities that are either physically or virtually embodied have been compared regarding the question if one form of embodiment might outperform the other, with no clear answer so far. Besides embodiment, many variables possibly affect evaluations and need to be taken into account when estimating the pure effect of being virtually or physi...
Conference Paper
Full-text available
Although both HRI and Communication Science often trace their origins to the transdisciplinary cybernetics of the 20th century, they have since developed in relative isolation, with scant scholarly exchange concerning the similarities and differences in their assumptions, insights, and approaches. The purpose of this half-day workshop is to explore...
Presentation
The discussion in the HRI-community on whether anthropomorphism and transparent behavior can and should go hand in hand, gained more and more attention lately. The present study explores how the style of speech a robot uses to present transparency relevant information can contribute to this discussion. The preliminary results show that compared to...
Article
This methodological article discusses the influence of individuals’ beliefs about their abilities to use and control robotic technologies on their evaluation of human-robot-interaction (HRI). We conducted three surveys to develop and validate a new measure of Self-Efficacy in HRI. Exploratory factor analysis revealed a two-factorial (factors percei...

Research demonstrated that humans are able to interpret humanlike (affective) nonverbal behavior (HNB) in artificial entities (e.g. Beck et al., in: Proceedings of the 19th IEEE international symposium on robot and human interactive communication, IEEE Press, Piscataway, 2010. https://doi.org/10.1109/ROMAN.2010.5598649; Bente et al. in J Nonverbal...
Article
It has been argued that reported negative effects of social networking site use on well-being and depression might be due to the vast opportunities for unflattering social comparison on Facebook. Social media websites offer Likes, a numeric representation of social acceptance, as a form of “online social currency,” which can be seen as a secondary...

Full-text available
Most applications for virtual agents require the user to cooperate. Thus, it is helpful to investigate different strategies for virtual agents to evoke the user’s cooperation. In the present work ( N = 80), we experimentally tested the influence of an agent’s (non)cooperative nonverbal behavior and actual decision-making behavior on user’s cooperat...
Article
Full-text available
In this paper, we present three experimental studies in which subjects trained a robot to do a card game via reinforcement learning. In the first two studies participants interacted with the robot either without any learning ability (control group) or with one out of three versions of a learning algorithm implementing gradually aspects of more huma...
Article
In this work, we explore the effects of dominant nonverbal behavior of a virtual agent on users in different age groups regarding their evaluations of the system as well as persuasion. We report a bipartite experimental laboratory study with young adults (N = 87) and seniors (N = 38). In the first part of the study, young adults interacted with the...
Chapter
Current studies investigating natural human–robot interaction (HRI) in the field concentrate on the analysis of automatically assessed data (e.g., interaction times). What is missing to date is a more qualitative approach to investigate the natural and individual behavior of people in HRI in detail. In a quasi-experimental observational field study...
Conference Paper
This study, investigates whether stress reducing effects as they are known from human-human interaction also occur while humans interact with robots. To analyze the individual stress level, 63 participants were asked about their stress level before and after they interacted with a humanoid robot. Three different conditions of touch behavior were an...
Conference Paper
We present an experimental online study examining how participants (N=343) interpret affectively congruent and incongruent body movements/gestures and non-linguistic utterances (NLUs).
Conference Paper
We propose a new theoretical framework assuming that embodiment effects in HAI and HRI are mediated by users' perceptions of an artificial entity's body-related capabilities. To enable the application of our framework to foster more theoretical-driven research, we developed a new self-report measurement that assesses bodilyrelated perceptions of th...
Conference Paper
Full-text available
The goal of this work is to explore the influence of do-it-yourself customization of a robot on technologically experienced students and unexperienced elderly users' perceived self-efficacy in HRI, uncertainty, and evaluation of the robot and interaction. We introduce the Self-Efficacy in HRI Scale and present two experimental studies. In study 1 (...

Full-text available
When designing an artificial tutor, the question arises: should we opt for a virtual or a physical embodied conversational agent? With this work we contribute to the ongoing debate of whether, when and how virtual agents or robots provide more benefits to the user and conducted an experimental study on linguistic alignment processes in HCI in the c...
Conference Paper
In order to design a successful human-agent-interaction, knowledge about the effects of a virtual agent’s behavior is important. Therefore, the presented study aims to investigate the effect of different nonverbal behavior on the agent’s person perception with a focus on dominance and cooperativity. An online study with 190 participants was conduct...
Conference Paper
Full-text available
In an attempt to replicate earlier research on intelligent agents for robots, we analysed the effects of the presence and absence of a robot’s nonverbal behavior on users’ nonverbal behavior and evaluation with a between subjects experimental study (N = 90). Results demonstrated that when the robot shows nonverbal behavior (head movement and deicti...

Full-text available
While the uncanny valley is definitely one of the most prominent theoretical assumptions in Human-Robot Interaction research, an inconsiderate appraisal of it will not benefit the research field and foster continuous exaggerations of its impact on robot acceptance. Thus, while we largely agree MacDorman & Entezari (2014) and acknowledge the importa...
Conference Paper
Full-text available
Robot companions should be able to perform a variety of different tasks and to adapt to the user's needs as well as to changing circumstances. To achieve this we can either built fully adaptive robots or adaptable and customizable robots. In this paper we present an adaptable companion which uses a decision making algorithm and user feedback to lea...
