(2018): The multi-modal interface of Robot-Era multi-robot services tailored for the elderly. In: Intelligent Service Robotics 11 (1), S. 109-126. DOI: 10.1007/s11370-017-0237-6
DOI: http://search.ebscohost.com/login.aspx?direct=true&db=psyh&AN=2018-02230-008&site=ehost-live Abstract: Socially assistive robotic platforms are now a realistic option for the long-term care of ageing populations. Elderly users may benefit from many services provided by robots operating in different environments, such as providing assistance inside apartments, serving in shared facilities of buildings or guiding people outdoors. In this paper, we present the experience gained within the EU FP7 ROBOT-ERA project towards the objective of implementing easy-to-use and acceptable service robotic system for the elderly. In particular, we detail the user-centred design and the experimental evaluation in realistic environments of a web-based multi-modal user interface tailored for elderly users of near future multi-robot services. Experimental results demonstrate positive evaluation of usability and willingness to use by elderly users, especially those less experienced with technological devices who could benefit more from the adoption of robotic services. Further analyses showed how multi-modal modes of interaction support more flexible and natural elderly–robot interaction, make clear the benefits for the users and, therefore, increase its acceptability. Finally, we provide insights and lessons learned from the extensive experimentation, which, to the best of our knowledge, is one of the largest experimentation of a multi-robot multi-service system so far.

(2018) : Towards playful learning and computational thinking — Developing the educational robot BRICKO: 2018 IEEE Integrated STEM Education Conference (ISEC): 2018 IEEE Integrated STEM Education Conference (ISEC): Princeton, United States: IEEE, S. 37-44
DOI: https://doi.org/10.1109/ISECon.2018.8340502 Abstract: Educational Robotics has proven a feasible way of supporting and exemplifying Computational Thinking. With this paper, we describe the user-centered iterative and incremental development of a new educational robotic system, BRICKO, to support tangible, social and playful interaction while educating children in 1 st -3 rd grade in Computational Thinking. We develop the system through seven main iterations including a total of 108 participant pupils and their teachers. The methodology is a mixture of observation and interviews using Wizard of OZ testing with the early pilot prototypes as well as usability and user experience testing with the following incrementally improved digital prototypes. Our results for development and evaluation are presented for each iteration leading onto the next and describes the evolution of both the BRICKO driving robot as well as the BRICKO programming-board and its different categories of command-bricks. We discuss the methodologies used for assuring a playful and social educational robotic system and conclude that we achieved a useful prototype for supporting education in Computational Thinking.

(2017) : Feasibility of using sphero in rehabilitation of children with autism in social and communication skills: 2017 26th IEEE International Symposium on Robot and Human Interactive Communication (RO-MAN): Lisbon, Portugal: IEEE Robotics & Automation Society, S. 989-994
DOI: https://doi.org/10.1109/ICORR.2017.8009378 Abstract: The majority of children with autism face difficulties in social interaction and communication skills. Consequently, in this paper we present a pilot study in which we explored the usability of Sphero TM as a rehabilitation tool for developing social and communication skills. We designed an interactive scenario where children with autism should verbally control the robot and utter voice commands. Our observations show that the children were very interested to interact with the robot in the given framework. They showed surprising behaviors that are promising evidences of effectiveness of using Sphero in rehabilitation of social and communication deficits.

(2017): Robot ZORA in rehabilitation and special education for children with severe physical disabilities: A pilot study. In: International Journal of Rehabilitation Research 40 (4), S. 353-359. DOI: 10.1097/MRR.0000000000000248
DOI: https://doi.org/10.1097/MRR.0000000000000248 Abstract: The aim of this study was to explore the potential of ZORA robot-based interventions in rehabilitation and special education for children with severe physical disabilities. A two-centre explorative pilot study was carried out over a 2.5-month period involving children with severe physical disabilities with a developmental age ranging from 2 to 8 years. Children participated in six sessions with the ZORA robot in individual or in group sessions. Qualitative and quantitative methods were used to collect data on aspects of feasibility, usability, barriers and facilitators for the child as well as for the therapist and to obtain an indication of the effects on playfulness and the achievement of goals. In total, 17 children and seven professionals participated in the study. The results of this study show a positive contribution of ZORA in achieving therapy and educational goals. Moreover, sessions with ZORA were indicated as playful. Three main domains were indicated to be the most promising for the application of ZORA: movement skills, communication skills and cognitive skills. Furthermore, ZORA can contribute towards eliciting motivation, concentration, taking initiative and improving attention span of the children. On the basis of the results of the study, it can be concluded that ZORA has potential in therapy and education for children with severe physical disabilities. More research is needed to gain insight into how ZORA can be applied best in rehabilitation and special education. (PsycINFO Database Record (c) 2018 APA, all rights reserved)

(2016): Social service robots to support independent living: Experiences from a field trial. In: Zeitschrift für Gerontologie und Geriatrie 49 (4), S. 282-287. DOI: 10.1007/s00391-016-1067-4
DOI: http://search.ebscohost.com/login.aspx?direct=true&db=psyh&AN=2016-29012-003&site=ehost-live Abstract: Background: Assistive robots could be a future means to support independent living for seniors. Objective: This article provides insights into the latest developments in social service robots (SSR) based on the recently finished HOBBIT project. The idea of the HOBBIT project was to develop a low-cost SSR which is able to reduce the risk of falling, to detect falls and handle emergencies in private homes. The main objective of the project was to raise the technology to a level that allows the robot to be fully autonomously deployed in the private homes of older users and to evaluate technology market readiness, utility, usability and affordability under real-world conditions. Method: During the initial phase of the project, a first prototype (PT1) was developed. The results of laboratory tests with PT1 were used for the development of a second prototype (PT2), which was finally tested in seven households of senior adults (mean age 79 years) for 3 weeks each, i.e. in total more than 5 months. Results: The results showed that PT2 is intuitive to handle and that the functions offered meet the needs of older users; however, the robot was considered more as a toy than a supportive device for independent living. Furthermore, despite an emergency function of the robot, perceived security did not increase. Conclusion: Reasons for this might be a lack of technological robustness and slow performance of the prototype and also the good health conditions of the users; however, users believed that a market-ready version of the robot would be vital for supporting people who are more fragile and more socially isolated. Thus, SSRs have the potential to support independent living of older people although the technology has to be considerably improved to reach market readiness.

(2015): Robotic companions for older people: A case study in the wild. In: Annual Review of CyberTherapy and Telemedicine 13, S. 147-152. Online verfügbar unter http://search.ebscohost.com/login.aspx?direct=true&db=psyh&AN=2016-13187-026&site=ehost-live
Abstract: Older people tend to have difficulties using unknown technical devices and are less willing to accept technical shortcomings. Therefore, a robot that is supposed to support older people in managing daily life has to adapt to the users' needs and capabilities that are very heterogeneous within the target group. The aim of the presented case study was to provide in-depth insights on individual usage patterns and acceptance of a mobile service robot in real live environments (i.e. in the users' homes). Results from three cases (users aged 67, 78 and 85 living in their own apartments) are reported. Findings on usability and user experience illustrate that the robot has considerable potential to be accepted to support daily living at home.

(2014): Development of a socially believable multi-robot solution from town to home. In: Cognitive Computation 6 (4), S. 954-967. DOI: 10.1007/s12559-014-9290-z
DOI: https://doi.org/10.1007/s12559-014-9290-z Abstract: Technological advances in the robotic and ICT fields represent an effective solution to address specific societal problems to support ageing and independent life. One of the key factors for these technologies is that they have to be socially acceptable and believable to the end-users. This paper aimed to present some technological aspects that have been faced to develop the Robot-Era system, a multi-robotic system that is able to act in a socially believable way in the environments daily inhabited by humans, such as urban areas, buildings and homes. In particular, this paper focuses on two services—shopping delivery and garbage collection—showing preliminary results on experiments conducted with 35 elderly people. The analysis adopts an end-user-oriented perspective, considering some of the main attributes of acceptability: usability, attitude, anxiety, trust and quality of life.

(2012) : Rethinking the human-agent relationship: Which social cues do interactive agents really need to have? In: Hingston, Philip: Believable bots: Can computers play like people?: New York, NY: Springer-Verlag Publishing, S. 1-28. Online verfügbar unter http://search.ebscohost.com/login.aspx?direct=true&db=psyh&AN=2013-00699-001&site=ehost-live
Abstract: This chapter discusses the potential meaning of the term social in relation to human-agent interaction. Based on the sociological theory of object-centred sociality, four aspects of sociality, namely forms of grouping, attachment, reciprocity, and reflexivity are presented and transferred to the field of human-humanoid interaction studies. Six case studies with three different types of humanoid robots are presented, in which the participants had to answer a questionnaire involving several items on these four aspects. The case studies are followed by a section on lessons learned for human-agent interaction. In this section, a 'social agent matrix' for categorizing human-agent interaction in terms of their main sociality aspect is introduced. A reflection on this matrix and the future (social) human-agent relationship closes this chapter. (PsycINFO Database Record (c) 2019 APA, all rights reserved)

(2011): Looking forward to a 'robotic society'?: Notions of future human-robot relationships. In: International Journal of Social Robotics 3 (2), S. 111-123. DOI: 10.1007/s12369-010-0076-5
DOI: https://doi.org/10.1007/s12369-010-0076-5 Abstract: This article reports on an explorative investigation comparing the notions of future human-robot relationships of the participants of a user study who interacted with a humanoid robot for the first time on the one hand, and those of experts from the industry on the other hand. By means of in-depth interviews, data on the following topics was gathered from 52 user study participants and six experts: (1) quality of life, health, and security, (2) working conditions and employment, (3) education, (4) cultural context. A content analysis of the interview material derived five key aspects of the future 'robotic society': (1) replacement, (2) competition, (3) safety and supervision, (4) increasing productivity, (5) cost and benefit assessment. Furthermore, a description of what makes a robot different from a machine or a human could be obtained. Additionally, the interviews were supplemented by two standardized questionnaires to measure the participants’ general attitude and acceptance towards robots. The article highlights the difference regarding viewpoints and understandings of the future human-robot relationships between novice users and experts.
