Smart kitchen for Ambient Assisted Living

El envejecimiento de la población es una realidad en todos los países desarrollados. Las predicciones de crecimiento de esta población son alarmantes, planteando un reto para los servicios sociales y sanitarios. Las personas ancianas padecen diversas discapacidades que se van acentuando con la edad, siendo más propensas a sufrir accidentes domésticos, presentando problemas para realizar tareas cotidianas, etc. Esta situación conlleva a una pérdida paulatina de capacidades que en muchas ocasiones acaba con la vida autónoma de la persona. En este contexto, las Tecnologías de la Información y Comunicación (TIC) aplicadas al entorno doméstico pueden jugar un papel importante, permitiendo que las personas ancianas vivan más tiempo, de forma independiente en su propio hogar, presentando, por tanto, una alternativa a la hospitalización o institucionalización de las mismas. Este trabajo da un paso más en este sentido, presentando el diseño y desarrollo de un Ambiente Inteligente en la cocina, que ayuda a las personas ancianas y/o con discapacidad a desempeñar sus actividades de la vida diaria de una forma más fácil y sencilla. Esta tesis realiza sus principales aportaciones en dos campos: El metodológico y el tecnológico. Por un lado se presenta una metodología sistemática para extraer necesidades de colectivos específicos a fin de mejorar la información disponible por el equipo de diseño del producto, servicio o sistema. Esta metodología se basa en el estudio de la interacción Hombre-Máquina en base a los paradigmas y modelos existentes y el modelado y descripción de las capacidades del usuario en la misma utilizado el lenguaje estandarizado propuesto en la Clasificación Internacional del Funcionamiento, de la Discapacidad y de la Salud (CIF). Adicionalmente, se plantea el problema de la evaluación tecnológica, diseñando la metodología de evaluación de la tecnología con la finalidad de conocer su accesibilidad, funcionalidad y usabilidad del sistema desarrollado y aplicándola a 61 usuarios y 31 profesionales de la gerontología. Desde un punto de vista técnico, se afronta el diseño de un ambiente asistido inteligente (Ambient Assisted Living, AAL) en la cocina, planteando y definiendo la arquitectura del sistema. Esta arquitectura, basada en OSGi (Open Services Gateway initiative), oferta un sistema modular, con altas capacidades de interoperabilidad y escalabilidad. Además, se diseña e implementa una red de sensores distribuida en el entorno con el fin de obtener la mayor información posible del contexto, presentando distintos algoritmos para obtener información de alto nivel: detección de caídas o localización. Todos los dispositivos presentes en el entorno han sido modelados utilizando la taxonomía propuesta en OSGi4AmI, extendiendo la misma a los electrodomésticos más habituales de la cocina. Finalmente, se presenta el diseño e implementación de la inteligencia del sistema, que en función de la información procedente del contexto y de las capacidades del usuario da soporte a las principales actividades de la vida diaria (AVD) en la cocina

Virtual fitting trials in 'design for all'

’Design for All’ embraces the concept of designing products and workplaces so as not to exclude significant sections of the total user population. In particular the needs of old and disabled people are to be considered alongside the younger and able-bodied population to ensure that products that are equally appropriate for all users. This is to be contrasted with a ’Design for the Disabled’ approach where the special needs of disabled people are considered in order to provide products that may only be appropriate for that section of society. Fitting trials are an established technique in ergonomics where a product or workplace is evaluated by trials (perhaps on a mock-up or prototype) using a carefully selected user group that is representative of the total target population. Typically subject selection would be based on age, gender, size, etc, and total sample sizes limited to perhaps a few dozen. A percentage of the population accommodated by the design can then be determined by reference to a set of elemental tasks such as reaching to controls. In this research the fitting trials are virtual in that computer modelling techniques are used to create a three-dimensional geometric model of the workplace/product and evaluation is achieved using a human model that can be varied to represent the individuals within the sample. There is a lack of anthropometric and biomechanical data relating to older and disabled people so a small-scale survey is being undertaken so that an appropriate population of computer human models can be created. Methods are being developed to allow the percentage accommodated by a design to be determined in relation to a description of tasks to be carried out. Currently an ATM (Automated Teller Machine) design is being used as a case study to develop these techniques. Further research will eventually be undertaken to extend the data, generalise the percentage accommodation evaluation and to optimise the design in terms of percentage accommodation

Designing for designers: Towards the development of accessible ICT products and services using the VERITAS framework

Among key design practices which contribute to the development of inclusive ICT products and services is user testing with people with disabilities. Traditionally, this involves partial or minimal user testing through the usage of standard heuristics, employing external assisting devices, and the direct feedback of impaired users. However, efficiency could be improved if designers could readily analyse the needs of their target audience. The VERITAS framework simulates and systematically analyses how users with various impairments interact with the use of ICT products and services. Findings show that the VERITAS framework is useful to designers, offering an intuitive approach to inclusive design.The work presented in this article forms part of VERITAS, which is funded by the European Commission's 7th Framework Programme (FP7) (grant agreement # 247765 FP7-ICT-2009.7.2)

City without barriers, ICT tools for the universal accessibility: study cases in Barcelona

Financed in the framework of the Call 2013, of the Program RecerCaixa (RecerCaixa and ACUP)This paper is the presentation of the results and developed tasks in the framework of the research project titled City without barriers. Tool for the evaluation and visualization of the accessibility into public space, using TLS, GIS and GPS Technologies,1 developed during 2014 and 2015 by the authors and others researchers and technicians in the Centre of Land Policy and Valuations (CPSV) and the Virtual City Modelling Lab (LMVC) of the Technical University of Catalonia (UPC) The main goal of the applied research project was the development of a tool to assess the degree of accessibility and calculate optimal routes in public space, and above all their incorporation into an integral system (tool), with accessibility information, services, and support's content. This tool has been developed in two formats, Web platform and App, and the App can be downloaded in situ and remotely via Web. This has been achieved, by steps, and the first one has been the development of a methodology to facilitate universal access to public space, evaluating and obtaining optimal routes for the users. This methodology has been based in the use of ICT, specifically the terrestrial laser scanner (LTS), a tool of high precision that allows obtain information of the space with a high degree of accuracy and high quality and get measurable information directly, combined with Geographical Information Systems and GPS. The starting premises were: 1. Increasing the information about accessibility to urban spaces, based on new demands, demographic changes, legal requirements or elder people and moving/visual disabilities needs. 2. Developing technological and strategic progresses in order to highlight universal accessibility and its associated information, as a need and an added value to the city

Inclusion in Virtual Reality Technology: A Scoping Review

Despite the significant growth in virtual reality applications and research, the notion of inclusion in virtual reality is not well studied. Inclusion refers to the active involvement of different groups of people in the adoption, use, design, and development of VR technology and applications. In this review, we provide a scoping analysis of existing virtual reality research literature about inclusion. We categorize the literature based on target group into ability, gender, and age, followed by those that study community-based design of VR experiences. In the latter group, we focus mainly on Indigenous Peoples as a clearer and more important example. We also briefly review the approaches to model and consider the role of users in technology adoption and design as a background for inclusion studies. We identify a series of generic barriers and research gaps and some specific ones for each group, resulting in suggested directions for future research

Accessibility of Health Data Representations for Older Adults: Challenges and Opportunities for Design

Health data of consumer off-the-shelf wearable devices is often conveyed to users through visual data representations and analyses. However, this is not always accessible to people with disabilities or older people due to low vision, cognitive impairments or literacy issues. Due to trade-offs between aesthetics predominance or information overload, real-time user feedback may not be conveyed easily from sensor devices through visual cues like graphs and texts. These difficulties may hinder critical data understanding. Additional auditory and tactile feedback can also provide immediate and accessible cues from these wearable devices, but it is necessary to understand existing data representation limitations initially. To avoid higher cognitive and visual overload, auditory and haptic cues can be designed to complement, replace or reinforce visual cues. In this paper, we outline the challenges in existing data representation and the necessary evidence to enhance the accessibility of health information from personal sensing devices used to monitor health parameters such as blood pressure, sleep, activity, heart rate and more. By creating innovative and inclusive user feedback, users will likely want to engage and interact with new devices and their own data

O papel da quarta revolução industrial no turismo acessível: estudo e conceptualização de uma aplicação web

The world is experiencing the beginning of the fourth Industrial Revolution, responsible for implementing a new digitalization era. This revolution originated in manufacturing, with industry 4.0 bringing a new reality to organizations. However, the scope of this new technological revolution is vast, and other sectors can benefit from the new digital era. In the Services Industry, tourism is an example of that, as Tourism 4.0 is the result of the impact of the fourth industrial revolution in this sector. Tourism 4.0 is the result of the impact of the fourth industrial revolution in tourism. An interesting challenge that this technological era brings to tourism is the social inclusion of people with disabilities. The accessible tourism market reveals huge potential, but despite this, this market is still largely ignored. Several technologies that promoted the fourth industrial revolution present capabilities to promote accessible tourism by improving tourism’s access conditions to people with disabilities. The present work developed a study in accessible tourism, understanding the main requirements for this market, and conceptualizing a Web application, for promoting accessibility in tourism. This Web application work as a mediator between the principal stakeholders. To gather requirements for the system, a triangulation matrix was elaborated using three methodological approaches: i) Literature Review; ii) website accessibility analysis of hotels located in the central region of Portugal; and iii) content analysis of some concurrent platforms. The requirements triangulation matrix allowed the identification of what requirements are crucial for the system success, which were used to conceptualize the solution with UML notation. This work intends to demonstrate the technological impacts of the fourth industrial revolution on society, especially on the promotion of a more accessible tourismO mundo encontra-se hoje no início da quarta revolução industrial, responsável pela promoção de uma nova era caracterizada pela digitalização. Apesar desta revolução ter surgido no setor industrial, com o conceito de Indústria 4.0, a sua aplicação é muito mais vasta, existindo outros sectores que podem igualmente beneficiar desta nova era tecnológica. O setor dos serviços, nomeadamente o Turismo, é um exemplo disso, e o conceito de Turismo 4.0 é o resultado do impacto da quarta revolução industrial nesse setor. Um desafio interessante que esta nova era tecnológica traz para o turismo é o da inclusão social, promovendo o turismo para todos. De facto, o mercado do turismo acessível, apesar de ter imenso potencial, tem sido relegado no contexto dos negócios. Por outro lado, o potencial tecnológico associado a esta nova revolução industrial sugere uma grande capacidade na promoção do turismo acessível, na medida em que podem facilitar as condições de acesso ao turismo, por parte de pessoas com algum tipo de incapacidade e ou necessidade especial. O presente trabalho visa conduzir um estudo na área do turismo acessível, por forma compreender os principais requisitos deste tipo de mercado e, consequentemente, conceptualizar uma aplicação Web, com o propósito de promover a acessibilidade no turismo, funcionando como um mediador de informação entre os principais stakeholders. Para a obtenção dos requisitos do sistema foi feita: i) uma revisão da literatura; ii) um estudo que avalia a acessibilidade dos websites dos hotéis da zona centro de Portugal, e, ainda iii) um estudo com base em análise de conteúdo de algumas plataformas potencialmente concorrentes. Os resultados são apresentados na forma de uma matriz de triangulação, onde é possível identificar a fonte dos requisitos identificados, sendo posteriormente utilizados para conceptualizar a solução proposta com recurso à notação UML. Pretende-se com este trabalho demonstrar o potencial e o efeito que as tecnologias existentes na era designada por quarta revolução industrial podem ter na sociedade, nomeadamente na promoção de um turismo para todosMestrado em Engenharia e Gestão Industria

Transforming our World through Universal Design for Human Development

An environment, or any building product or service in it, should ideally be designed to meet the needs of all those who wish to use it. Universal Design is the design and composition of environments, products, and services so that they can be accessed, understood and used to the greatest extent possible by all people, regardless of their age, size, ability or disability. It creates products, services and environments that meet people’s needs. In short, Universal Design is good design. This book presents the proceedings of UD2022, the 6th International Conference on Universal Design, held from 7 - 9 September 2022 in Brescia, Italy.The conference is targeted at professionals and academics interested in the theme of universal design as related to the built environment and the wellbeing of users, but also covers mobility and urban environments, knowledge, and information transfer, bringing together research knowledge and best practice from all over the world. The book contains 72 papers from 13 countries, grouped into 8 sections and covering topics including the design of inclusive natural environments and urban spaces, communities, neighborhoods and cities; housing; healthcare; mobility and transport systems; and universally- designed learning environments, work places, cultural and recreational spaces. One section is devoted to universal design and cultural heritage, which had a particular focus at this edition of the conference. The book reflects the professional and disciplinary diversity represented in the UD movement, and will be of interest to all those whose work involves inclusive design
