(2018): Toward Socially Aware Person-Following Robots. In: IEEE Transactions on Cognitive and Developmental Systems 10 (4), S. 936-954. DOI: 10.1109/TCDS.2018.2825641
DOI: https://doi.org/10.1109/TCDS.2018.2825641 Abstract: Significant research and development has been invested in technical issues related to person following. However, a systematic approach for designing robotic person-following behavior that maintains appropriate social conventions across contexts has not yet been developed. To understand why this may be the case, an in-depth literature review of 221 articles on person-following robots was performed, from which 107 are referenced. From these papers, six relevant topics were identified that shed light on the types of social interactions that have been studied in person-following scenarios: 1) applications; 2) robotic systems; 3) environments; 4) following strategies; 5) human-robot communication; and 6) evaluation methods. Gaps in the existing research on person-following robots were identified, mainly in addressing social interaction and user needs, noting that only 25 articles reported proper user studies. Human-related, robot-related, task-related, and environment-related factors that are likely to influence people’s spatial preferences and expectations of a robot’s person-following behavior are then discussed. To guide the design of socially aware person following robots, a user-needs layered design framework that combines the four factor categories is proposed. The framework provides a systematic way to incorporate social considerations in the design of person-following robots. Finally, framework limitations and future challenges in the field are presented and discussed.

(2017) : On how self-body awareness improves autonomy in social robots: 2017 IEEE International Conference on Robotics and Biomimetics (ROBIO): Parisian Macao, China: IEEE, S. 1688-1693
DOI: https://doi.org/10.1109/ROBIO.2017.8324661 Abstract: Just as humans show consciousness of their body, social robots, in the way to be truly autonomous need to be aware of their body posture. Feasible gestures, moves and actions depend on the current body posture. The work developed in this paper aims to empirically show how self configuration recognition augments the degree of autonomy of a robot in the context of entertainment robotics. The integration of a classification tree for body posture identification based on data acquired from proprioceptive sensors of a NAO robot allows to interact with the robot in a more flexible and persistent manner. As a result, the robot shows a more sound behavior and greater degree of autonomy. Moreover, even if the body-awareness has been developed for minstrel robots, its application can be generalized to other contexts.

(2017) : A study on the social acceptance of a robot in a multi-human interaction using an F-formation based motion model: 2017 IEEE/RSJ International Conference on Intelligent Robots and Systems (IROS): Vancouver, British Columbia, Canada: IEEE, S. 2766-2771
DOI: https://doi.org/10.1109/IROS.2017.8206105 Abstract: As robots participate in human’s daily activities more and more frequently, mobility performance has become one of the main factors determining how robots will share an environment with humans harmoniously in the near future. Among several different kinds of mobile platforms, using omnidirectional configurations is gradually becoming a trend in the robotics community; however, few researchers have addressed the impact of omnidirectional mobility from the perspective of human-robot interaction (HRI). In this paper, we have proposed a socializing model for the robot while participating in an interaction with a group of human peers to achieve its socially optimal position. From a theoretic perspective, we first identify the most prominent features required for social acceptance of robots interacting with multiple humans, backing our arguments with relevant sociological theory. To validate our results, we have conducted experiments where human participants were invited to interact with a robot, which can be constrained to perform either holonomic or nonholonomic motions only. Then, through an observer survey, we testify the appropriateness of utilizing omnidirectional mobility and verify the promotion of social acceptance using the aforementioned features, which is a goal that both the HRI and robotics communities aim to achieve.

(2016) : Who should robots adapt to within a multi-party interaction in a public space?: 2016 11th ACM/IEEE International Conference on Human-Robot Interaction (HRI): Christchurch, New Zealand: IEEE Press, S. 483-484
DOI: https://doi.org/10.1109/HRI.2016.7451817 Abstract: Robots in public environments are challenged with socially appropriate interactions with previously unseen users: they need to offer appropriate services and shape their interaction style according to the particular individual’s needs and preferences, for example the elderly and children. In addition, interactions in public spaces are not limited to merely two parties, but often involve multi-party situations with changing numbers of participants. The research question of this work is to investigate what rules should a socially competent robot follow in order to adapt to such complex social situations in real-world scenarios.

(2015) : Perception of Affective Body Movements in HRI across Age Groups: Comparison between Results from Denmark and Japan: 2015 International Conference on Culture and Computing (Culture Computing): Kyoto, Japan: IEEE, S. 25-32
DOI: https://doi.org/10.1109/Culture.and.Computing.2015.14 Abstract: Social robots are envisioned to move into unrestricted environments where they will be interacting with naive users (in terms of their experience as robot operators). Thus, these robots are also envisioned to exploit interaction channels that are natural to humans like speech, gestures, or body movements. A specificity of these interaction channels is that humans do not only convey task-related information but also more subtle information like e.g. Emotions or personal stance through these channels. Thus, to be successful and not accidentally jeopardizing an interaction, robots need to be able to understand these implicit connotations of the signals (often called social signal processing) in order to generate appropriate signals in a given interaction context. One main application area that is envisioned for social robots is related to elder care, but little is known on how seniors will perceive robots and the signals they produce. In this paper we focus on affective connotations of body movements and investigate how the perception of body movements of robots is related to age. Inspired by a study from Japan, we introduce culture as a variable in the experiment and discuss the difficulties of cross-cultural comparisons. The results show that there are certain age-related differences in the perception of affective body movements, but not as strong as in the original study. A follow up experiment puts the affective body movements into context and shows that recognition rates deteriorate for older participants.

(2014) : Socially-appropriate approach paths using human data: The 23rd IEEE International Symposium on Robot and Human Interactive Communication: Edinburgh, Scotland: IEEE, S. 1037-1042
DOI: https://doi.org/10.1109/ROMAN.2014.6926389 Abstract: For service robots operating in indoor environments, the crucial task of navigation is often complicated by the presence of people. Simply treating humans in the environment as additional (often moving) obstacles can violate the complex set of social rules by which people navigate around each other. In contrast, emulating human behavior and navigating in a socially appropriate manner could positively affect people’s comfort with a robot’s presence and motion. We present a method of generating social paths for a robot to approach a person based on a small amount of human data. We also conducted a study in which a robot approached participants using both these social paths and straight-line, nonsocial paths. We found that both approaches were rated comparably when the robot approached from the participant’s front or side, but the social approach was significantly preferred when the robot came from behind the participant.

(2014) : Robot Etiquette: How to Approach a Pair of People?: 2014 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI): 2014 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI): Bielefeld, Germany: Association for Computing Machinery, S. 196-197
Abstract: Research has been carried out on robots approaching one person [1, 3, 4]. However, further research is needed on robots approaching groups of people. In the study reported in this paper, we studied participants who were paired up for a task and assessed their perception and behaviors as they were approached by a robot from various angles. On an individual level, participants liked the frontal approaches, and they disliked being approached from the back. However, we found that the presence of a task-partner influenced participants’ comfort with a robot approaching (i.e. when the robot approaches and one is standing behind the task-partner). Apart from the positioning of the individuals, the layout of the room, position of furniture and doors, also seemed to influence their experience. This pilot study was performed with a limited number of participants (N=30). However, the study offers preliminary insights into the factors that influence the choice for a robot approach direction when approaching a pair of people that are focused on a task.

(2013) : Let the machines do. How intelligent is Artificial Intelligence?: 2013 36th International Convention on Information and Communication Technology, Electronics and Microelectronics (MIPRO): Opatija, Croatia: IEEE, S. 947-952
Abstract: “Intelligent” systems are present around us. Such machines are not only tools in our hands, they are able to make decisions and perform actions directly in the real world or in the artificial worlds of the internet. But even in the latter case, their decisions have consequences to our life. Many of them still act as “assistance systems”, leaving the final decision to the human user. The trend goes to more autonomy of the machines, even in critical situations when humans become overloaded by complexity. Additionally, humans are more and more willing to accept the proposals of the machines. But is this technique mature enough to guide or even to replace human decision-making? Especially, perception appears to be a hard problem for technical equipment. How accurate, how safe can decisions be in the case of incomplete and unreliable data? The paper gives some overview about recent developments in Artificial Intelligence and Robotics, their capabilities and serious problems from a general point of view.

(2007) : Robopal: Modeling Role Transitions in Human-Robot Interaction: Proceedings 2007 IEEE International Conference on Robotics and Automation: Roma, Italy: IEEE Robotics & Automation Society, S. 2130-2137
DOI: https://doi.org/10.1109/ROBOT.2007.363636 Abstract: We have developed a new communication robot, Robopal, which is an indoor/outdoor robot for use in human-robot interaction research in the context of daily life. Robopal’s intended applications involve leading and/or following a human to a destination. Preliminary experiments have been conducted to study nonverbal cues associated with leading and following behavior, and it has been observed that some behaviors, such as glancing towards the leader or follower, appear to be role-dependent. A system for representing these behaviors with a state transition model is described, based on four kinds of interaction roles: directive, responsive, collaborative, and independent. It is proposed that behavior modeling can be simplified by using this system to represent changes in the roles the robot and human play in an interaction, and by associating appropriate behaviors to each role
