State of the art of audio- and video based solutions for AAL

Working Group 3. Audio- and Video-based AAL ApplicationsIt is a matter of fact that Europe is facing more and more crucial challenges regarding health and social care due to the demographic change and the current economic context. The recent COVID-19 pandemic has stressed this situation even further, thus highlighting the need for taking action. Active and Assisted Living (AAL) technologies come as a viable approach to help facing these challenges, thanks to the high potential they have in enabling remote care and support. Broadly speaking, AAL can be referred to as the use of innovative and advanced Information and Communication Technologies to create supportive, inclusive and empowering applications and environments that enable older, impaired or frail people to live independently and stay active longer in society. AAL capitalizes on the growing pervasiveness and effectiveness of sensing and computing facilities to supply the persons in need with smart assistance, by responding to their necessities of autonomy, independence, comfort, security and safety. The application scenarios addressed by AAL are complex, due to the inherent heterogeneity of the end-user population, their living arrangements, and their physical conditions or impairment. Despite aiming at diverse goals, AAL systems should share some common characteristics. They are designed to provide support in daily life in an invisible, unobtrusive and user-friendly manner. Moreover, they are conceived to be intelligent, to be able to learn and adapt to the requirements and requests of the assisted people, and to synchronise with their specific needs. Nevertheless, to ensure the uptake of AAL in society, potential users must be willing to use AAL applications and to integrate them in their daily environments and lives. In this respect, video- and audio-based AAL applications have several advantages, in terms of unobtrusiveness and information richness. Indeed, cameras and microphones are far less obtrusive with respect to the hindrance other wearable sensors may cause to one’s activities. In addition, a single camera placed in a room can record most of the activities performed in the room, thus replacing many other non-visual sensors. Currently, video-based applications are effective in recognising and monitoring the activities, the movements, and the overall conditions of the assisted individuals as well as to assess their vital parameters (e.g., heart rate, respiratory rate). Similarly, audio sensors have the potential to become one of the most important modalities for interaction with AAL systems, as they can have a large range of sensing, do not require physical presence at a particular location and are physically intangible. Moreover, relevant information about individuals’ activities and health status can derive from processing audio signals (e.g., speech recordings). Nevertheless, as the other side of the coin, cameras and microphones are often perceived as the most intrusive technologies from the viewpoint of the privacy of the monitored individuals. This is due to the richness of the information these technologies convey and the intimate setting where they may be deployed. Solutions able to ensure privacy preservation by context and by design, as well as to ensure high legal and ethical standards are in high demand. After the review of the current state of play and the discussion in GoodBrother, we may claim that the first solutions in this direction are starting to appear in the literature. A multidisciplinary 4 debate among experts and stakeholders is paving the way towards AAL ensuring ergonomics, usability, acceptance and privacy preservation. The DIANA, PAAL, and VisuAAL projects are examples of this fresh approach. This report provides the reader with a review of the most recent advances in audio- and video-based monitoring technologies for AAL. It has been drafted as a collective effort of WG3 to supply an introduction to AAL, its evolution over time and its main functional and technological underpinnings. In this respect, the report contributes to the field with the outline of a new generation of ethical-aware AAL technologies and a proposal for a novel comprehensive taxonomy of AAL systems and applications. Moreover, the report allows non-technical readers to gather an overview of the main components of an AAL system and how these function and interact with the end-users. The report illustrates the state of the art of the most successful AAL applications and functions based on audio and video data, namely (i) lifelogging and self-monitoring, (ii) remote monitoring of vital signs, (iii) emotional state recognition, (iv) food intake monitoring, activity and behaviour recognition, (v) activity and personal assistance, (vi) gesture recognition, (vii) fall detection and prevention, (viii) mobility assessment and frailty recognition, and (ix) cognitive and motor rehabilitation. For these application scenarios, the report illustrates the state of play in terms of scientific advances, available products and research project. The open challenges are also highlighted. The report ends with an overview of the challenges, the hindrances and the opportunities posed by the uptake in real world settings of AAL technologies. In this respect, the report illustrates the current procedural and technological approaches to cope with acceptability, usability and trust in the AAL technology, by surveying strategies and approaches to co-design, to privacy preservation in video and audio data, to transparency and explainability in data processing, and to data transmission and communication. User acceptance and ethical considerations are also debated. Finally, the potentials coming from the silver economy are overviewed.publishedVersio

Conception d'un actionneur prismatique rétractable

Les robots parallèles entraînés par câbles (RPEC) permettent d'augmenter grandement l'espace de travail. Cependant, il est possible d'améliorer le ratio entre le volume de travail utile d'un RPEC et son volume replié en concevant un système capable de se rétracter pour laisser la place à d'autres types d'activités. L'objectif de ce mémoire consiste à concevoir un actionneur prismatique rétractable maximisant le volume de travail et résistant au ambage. Notre système est composé de deux chaînes de maillons qui s'emboîtent l'une dans l'autre à l'aide d'un guide convergent a n de former une poutre rigide. A l'extrémité de cette poutre, trois câbles sont implantés a n de la maintenir en compression et un e ecteur pourrait être installé. Dans un premier temps, nous avons présenté le système dans son ensemble, déterminé le volume de travail à maximiser ainsi que les contraintes à respecter. Nous avons sélectionné et dimensionné le système d'emboitement des maillons : les snap- ts. Ensuite, nous avons conçu une crémaillère intégrée aux maillons et les engrenages permettant de translater et assembler ces deux chaînes. Nous avons alors paramétrisé notre système a n de l'optimiser pour obtenir un volume de travail maximal. En n, nous avons conçu les réservoirs accueillant les deux chaînes et réalisé le prototype. Cela nous a permis de mesurer le rapport du volume de travail sur le volume rétracté égal à 11,58, ce qui signi e que nous avons atteint notre objectif. Nous avons testé la résistance au ambage du système qui pourrait être améliorée en corrigeant les jeux entre les maillons

Towards a Legal end Ethical Framework for Personal Care Robots. Analysis of Person Carrier, Physical Assistant and Mobile Servant Robots.

Technology is rapidly developing, and regulators and robot creators inevitably have to come to terms with new and unexpected scenarios. A thorough analysis of this new and continuosuly evolving reality could be useful to better understand the current situation and pave the way to the future creation of a legal and ethical framework. This is clearly a wide and complex goal, considering the variety of new technologies available today and those under development. Therefore, this thesis focuses on the evaluation of the impacts of personal care robots. In particular, it analyzes how roboticists adjust their creations to the existing regulatory framework for legal compliance purposes. By carrying out an impact assessment analysis, existing regulatory gaps and lack of regulatory clarity can be highlighted. These gaps should of course be considered further on by lawmakers for a future legal framework for personal care robot. This assessment should be made first against regulations. If the creators of the robot do not encounter any limitations, they can then proceed with its development. On the contrary, if there are some limitations, robot creators will either (1) adjust the robot to comply with the existing regulatory framework; (2) start a negotiation with the regulators to change the law; or (3) carry out the original plan and risk to be non-compliant. The regulator can discuss existing (or lacking) regulations with robot developers and give a legal response accordingly. In an ideal world, robots are clear of impacts and therefore threats can be responded in terms of prevention and opportunities in form of facilitation. In reality, the impacts of robots are often uncertain and less clear, especially when they are inserted in care applications. Therefore, regulators will have to address uncertain risks, ambiguous impacts and yet unkown effects

Out of Chaos: Reflections of a University President and His Contemporaries on Vietnam-Era Unrest in Mankato and Its Relevance Today

Out of Chaos: Reflections of a University President and his Contemporaries on Vietnam-era Unrest in Mankato and its Relevance Today is a collection of personal reminiscences that provide a glimpse into what Mankato was like during the 1960s and 1970s. The book was created by Dr. James F. Nickerson, former Mankato State College president, with input from a variety of graduates, faculty, administrators and citizens who were witnesses to these local events. It is by piecing these stories together that the reader gets an understanding of this dynamic time period and how one person can make a difference in the outcome of events. Minnesota State University, Mankato will observe its 150th anniversary as an institution of higher learning in 2018. Out of Chaos, represents a significant time in University’s past, and so to coincide with other Sesquicentennial undertakings, it is being reprinted as a Sesquicentennial Edition. Out of Chaos has also been selected as the 2017 Common Read book. As Minnesota State Mankato’s Common Read book for 2017, Out of Chaos will support the commemoration of the Sesquicentennial by allowing campus and community readers to explore the University’s remarkable history through book discussions, thought-provoking programming and other associated educational experiences.https://cornerstone.lib.mnsu.edu/university-archives-msu-authors/1000/thumbnail.jp

Rhoda: ‘Comrade Kadalie, You Are Out of Order!

This authorized biography was made possible through the gracious help of my mother-in-law, Rhoda Kadalie, who provided generous access to her files, letters, photographs, and extensive library of documents. She made time to sit with me for several hours of interviews from September through October 2021, to answer questions as they arose, and to offer innumerable clarifications. Rhoda also reviewed the first draft of the biography in December 2021, making corrections and additions, and contributing some of her own original vignettes, never before published

Discourses We Live By

"What are the influences that govern how people view their worlds? What are the embedded values and practices that underpin the ways people think and act? Discourses We Live By approaches these questions through narrative research, in a process that uses words, images, activities or artefacts to ask people – either individually or collectively within social groupings – to examine, discuss, portray or otherwise make public their place in the world, their sense of belonging to (and identity within) the physical and cultural space they inhabit. This book is a rich and multifaceted collection of twenty-eight chapters that use varied lenses to examine the discourses that shape people’s lives. The contributors are themselves from many backgrounds – different academic disciplines within the humanities and social sciences, diverse professional practices and a range of countries and cultures. They represent a broad spectrum of age, status and outlook, and variously apply their research methods – but share a common interest in people, their lives, thoughts and actions. Gathering such eclectic experiences as those of student-teachers in Kenya, a released prisoner in Denmark, academics in Colombia, a group of migrants learning English, and gambling addiction support-workers in Italy, alongside more mainstream educational themes, the book presents a fascinating array of insights. Discourses We Live By will be essential reading for adult educators and practitioners, those involved with educational and professional practice, narrative researchers, and many sociologists. It will appeal to all who want to know how narratives shape the way we live and the way we talk about our lives.
