Social robots: technological societal and ethical aspects of human robot interaction Social robots not only work with humans in collaborative workspaces – we meet them in shopping malls and even more personal settings like health and care. Does this imply they should become more human able to interpret and adequately respond to human emotions Do we want them to help elderly people Do we want them to support us when we are old ourselves Do we want them to just clean and keep things orderly – or would we accept them helping us to go to the toilet or even feed us if we suffer from Parkinson’s disease The answers to these questions differ from person to person. They depend on cultural background personal experiences – but probably most of all on the robot in question. This book covers the phenomenon of social robots from the historic roots to today’s best practices and future perspectives. To achieve this we used a hands on interdisciplinary approach incorporating findings from computer scientists engineers designers psychologists doctors nurses historians and many more. The book also covers a vast spectrum of applications from collaborative industrial work over education to sales. Especially for developments with a high societal impact like robots in health and care settings the authors discuss not only technology design and usage but also ethical aspects. Thus this book creates both a compendium and a guideline helping to navigate the design space for future developments in social robotics A Short History of the Perception of Robots and Automata from Antiquity to Modern Times Designing Social Robots at Scales Beyond the Humanoid A Study on Robot Initiated Interaction: Toward Virtual Social Behavior The Role of Gesture in Social Telepresence Robots A Scenario of Distant Collaborative Problem Solving Unobtrusive Vital Data Recognition by Robots to Enhance Natural Human Robot Communication Interacting With Collaborative Robots – A Study on Attitudes and Acceptance in Industrial Contexts A Social Robot in a Shopping Mall: Studies on Acceptance and Stakeholder Expectations Multi party Interaction in Public Spaces: Cross cultural Variations in Parental and Nonparental Response to Robots’ Adaptive Strategies Cross Collaborative Approach to Socially Assistive Robotics: A Case Study of Humanoid Robots in a Therapeutic Intervention for Autistic Children Social Robots and Human Touch in Care: The Perceived Usefulness of Robot Assistance among Healthcare Professionals Attitudes of Professionals toward the Need for Assistive and Social Robots in the Healthcare Sector Evaluating the Sense of Safety and Security in Human Robot Interaction with Older People AMIGO A Socially Assistive Robot for Coaching Multimodal Training of Persons with Dementia
