Age, Gender, and Technology Attitude as Factors for Acceptance of Smart Interactive Textiles in Home Environments - Towards a Smart Textile Technology Acceptance Model

Authors:

Philipp Brauner, Julia van Heek and Martina Ziefle

Abstract: Smart interactive textiles are the next frontier of ubiquitous computing and may serve as novel and accepted interfaces that go beyond conventional human-computer interaction. Apart from the technical perspective, it is important to understand if and under which conditions people adopt these technologies and which factors constitute perceived barriers of technology acceptance. In this work we examine people’s attitudes towards smart textiles and their relationship to the intention to use these products in their home environment. This article provides a precise modeling of younger and older people in regard to expertise in interacting with technology, their desire to control and automate functions in their home environment, and the evaluation of a smart cushion for controlling the home environment, using the Smart Textile Technology Acceptance Model that is derived from the Unified Theory of Acceptance and Use of Technology 2 model. This model was applied for a specific smart textile product and the evaluation was focused on user-diversity, attitudes, and age. The article concludes with open research questions and guidelines for practitioners to leverage the benefits of smart textile user interfaces.

Selection and Assessment of Activity Trackers for Enthusiastic Seniors

Authors:

Viktoria Willner, Harald Rieser, Verena Venek and Cornelia Schneider

Abstract: A large percentage of older people do not achieve the recommended levels of health related activities. The planned CARIMO system addresses this problem and offers services and applications which motivate older users to do exercises and thus, improve their health. As additional incentive, an activity tracker is planned to be integrated in the CARIMO system. The paper describes the three-step process we defined to select a suitable device. First, available activity trackers were analysed according to a predefined criteria catalogue. Best ranked trackers were evaluated with a respect to usability and technical requirements. The Samsung Gear Fit2 offered a high range of functionality and was best ranked according to the usability evaluation. So, we finally decided to integrate the Samsung Gear Fit2 in the CARIMO system.

Helpful but Spooky? Acceptance of AAL-systems Contrasting User Groups with Focus on Disabilities and Care Needs

Authors:

Julia van Heek, Simon Himmel and Martina Ziefle

Abstract: Ambient Assisted Living (AAL) technologies present one approach facing the challenges of recent and rising care needs due to demographic changes in western societies. Beside the technological implementation, the focus on user acceptance of all stakeholders plays a major role for a successful rollout. As most research deals with age-related issues, this paper emphasizes especially on the sector of disabled persons. In a qualitative interview pre-study (n=9) and a validating questionnaire study (n=279) the perceived benefits and barriers of AAL technologies were contrasted in four user groups: healthy “not-experienced” people, disabled, their relatives, and professional care givers. Results indicate that disabled and care-needy people show a higher acceptance and intention to use an AAL system than “not-experienced” people or care givers and that the motives for use and non-use differ strongly with regard to user diversity as well. The results show the importance to integrate diverse user groups (age, disabilities) into the design and evaluation process of AAL technologies.

Closer to Nature - Interactive Installation Design for Elderly with Dementia

Authors:

Carlijn Valk, Xu Lin, Loe Fijes, Matthias Rauterberg and Jun Hu

Abstract: Dementia is a serious degenerative neurological condition that affects cognition and memory, often accompanied with depression and anxiety. As explicit memory deteriorates, the implicit memory remains, so sensory stimulation and tangible solutions become increasingly important to people with dementia. This paper presents the design, implementation and evaluation process of Closer to Nature, an interactive installation aiming to provide opportunities for people with dementia in care facilities to feel more connected to nature. Closer to Nature aims to do so by combining the soothing effect of nature and the animal therapy via tangible interaction with tactile stimulation. Based on the feedback we collected, we analyse the insights from the interactive installation design for seniors with dementia in their living environment and discuss the potential of utilizing tangible interaction to help facilitate the supportive environment for the elderly.

Knowledge Security - An Empirical Use of IT – Child Abuse Monitor System Model

Authors:

Tiago Pereira and Henrique Santos

Abstract: The Information Security, nowadays, faces new threats such as the process of massive information in which are applied artificial intelligence techniques with the goal of predicting and classify our actions. Thus, knowledge about our behaviour, likes, dislikes, among others, leads us to consider that Knowledge Security appears has the natural evolution of Information Security. On the other side of the same coin we have new possibilities to monitor health, the wellbeing and abnormal symptoms, reactions to treatments, alert for insulin insufficiency, pacemaker malfunction, among others. Child abuse cases, it is a subject of most importance in our society, although, these cases are, from suspicion to signalization, difficult to identify since strong evidences are needed. Typically, health care services deal with these cases in an earlier stage with evidences based on the emergency diagnosis, but, yet, not sufficient and with lack of information, thus, further analysis is needed from experts’ teams. The main goal of these teams is to protect the child from the possibility of occurrence of more abuses. We have developed a prototype that automatically could predict and alert to situations that could be needed to use the measure of the protection of the child, Using digitalised child abuse processes, knowledge management and artificial intelligence techniques with 83% of true positives. In this research, we addressed both sides of the coin, Knowledge Security and the benefits of the Knowledge Discovery defining, in our opinion, the fourth generation of Knowledge Management - Value Creation and Knowledge.

Daily Activity Recognition based on Meta-classification of Low-level Audio Events

Authors:

Theodoros Giannakopoulos and Stasinos Konstantopoulos

Abstract: This paper presents a method for recognizing activities taking place in a home environment. Audio is recorded and analysed realtime, with all computation taking place on a low-cost Raspberry PI. In this way, data acquisition, low-level signal feature calculation, and low-level event extraction is performed without transferring any raw data out of the device. This first-level analysis produces a time-series of low-level audio events and their characteristics: the event type (e.g., ‘music’) and acoustic features that are relevant to further processing, such as energy that is indicative of how loud the event was. This output is used by a meta-classifier that extracts long-term features from multiple events and recognizes higher-level activities. The paper also presents experimental results on recognizing kitchen and living-room activities of daily living that are relevant to assistive living and remote health monitoring for the elderly. Evaluation on this dataset has shown that our approach discriminates between six activities with an accuracy of more than 90%, that our two-level classification approach outperforms one-level classification, and that including low-level acoustic features (such as energy) in the input of the meta-classifier significantly boosts performance.

A Home-based Early Risk Detection System for Congestive Heart Failure using a Bayesian Reasoning Network

Authors:

Athanasia Lappa and Christos Goumopoulos

Abstract: Congestive heart failure (CHF) is a progressive condition in which the heart is no longer capable of supplying adequate oxygenated blood to the body. Since the incidence of CHF increases with age, mainly due to the development of heart failure risk factors the epidemic of CHF is expected to grow further in the coming decades and thus becoming an important public health problem. In this paper we present a risk detection system for CHF that uses a Bayesian Network (BN) combined with health measurements that can be taken in a home environment using ambient assisted living technologies. The algorithm is empowered by employing statistical and medical analysis of the stored biological data and the output can be used as a basis for triggering proper preventive interventions. The BN design was established by surveying the relevant literature and consulting the domain expert. The network content combines both biometric variables that are daily monitored and data from patient’s clinical history as well as additional heart failure risk factors in terms of the EuroSCORE model. The predictive validity was tested with the involvement of the domain expert who specified proper validation rules in terms of criteria for detecting a CHF risk.

Gomez Aguilera, Hermie Hermens and Miriam Vollenbroek-Hutten

Abstract: In the face of demographic ageing European healthcare providers and policy makers are recognising an increasing prevalence of frail, community-dwelling older adults, prone to adverse healthcare outcomes. Prefrailty, before onset of functional decline, is suggested to be reversible but interventions targeting this risk syndrome are limited. No consensus on the definition, diagnosis or management of pre-frailty exists. The PERsonalised ICT Supported Service for Independent Living and Active Ageing (PERSSILAA) project (2013-2016 under Framework Programme 7, grant #610359) developed a comprehensive Information and Communication Technologies (ICT) supported platform to screen, assess, manage and monitor pre-frail community-dwelling older adults in order to address pre-frailty and promote active and healthy ageing. PERSSILAA, a multi-domain ICT service, targets three pre-frailty: nutrition, cognition and physical function. The project produced 42 recommendations across clinical (screening, monitoring and managing of pre-frail older adults) technical (ICT-based innovations) and societal (health literacy in older adults, guidance to healthcare professional, patients, caregivers and policy makers) areas. This paper describes the 25 healthcare related recommendations of PERSSILAA, exploring how they could be used in the development of future European guidelines on the screening and prevention of frailty.

Authors:

Danilo Coelho, Filipe Portela, Manuel Filipe Santos, José Machado and António Abelha

Abstract: Currently, the healthcare system is one of the main pillars of any society. Given the economic crisis in Portugal and poor healthcare system in need of profound improvements, the need to increase the efficiency of resource management and services is imperative. With the increasing use of Business Intelligence (BI) in organisations and the proven effectiveness of this, comes the desire to use BI in healthcare, specifically in the healthcare of Misericórdia. One of the purposes of this article is to present the results obtained through the development of the dissertation whose theme is "Prototyping of Business Intelligence component to support the management in the health area of a Misericórdia". So, in this work, some concepts associated with the use of BI in Misericórdias were addressed, and the Pervasive BI architecture of the developed solution was designed. It is also important to emphasise that the solution presented is pervasive, available anywhere at any time. Furthermore, a set of metrics were developed and the data presented in the form of dashboards, for later use by the users. Through this work, it was possible to gather all the data into a single structure (Data Mart), to identify a set of aspects that can be improved and to have a generalised view of the state of operation of the organisation, as far as health care is concerned.

A FHIR-based System for the Generation and Retrieval of Clinical Documents

Authors:

Crescenzo Diomaiuta, Mario Sicuranza, Mario Ciampi and Giuseppe De Pietro

Abstract: Clinical information exchange among heterogeneous systems is a complex process. It is necessary to use dictionaries, coding standards (e.g. LOINC and SNOMED), and terminology services, in order to: i) produce machine-interpretable information and coded data, ii) reduce information exchange complexity, and iii) allow the fulfillment of semantic interoperability among several systems. This work presents a system to support healthcare professionals in the creation of clinical documents using appropriate standards and in the information reading and retrieval of interest on clinical documents. The system allows healthcare professionals to use standard codes easily (via terminology server) during the creation of documents. Similarly, it also permits the decoding of health standard codes, during the read documents process, to facilitate the obtaining of information. In summary, it makes use of a simple and intuitive graphical user interface and a Fast Healthcare Interoperability Resources (FHIR) terminology server to support healthcare professionals in diagnosing and treating patients.

Mobile Technology to Monitor Physical Activity and Wellbeing in Daily Life - Objective and Subjective Experiences of Older Adults

Authors:

Miriam Cabrita, Monique Tabak and Miriam M.R. Vollenbroek-Hutten

Abstract: Older adults are not reaching the recommended guidelines for physical activity. There is growing evidence that physical activity and positive emotions reinforce each other. However, the development of interventions leveraging this knowledge faces several challenges, such as the limited knowledge on the assessment of emotional wellbeing in daily life using technology. In this study, we investigate the experience of older adults regarding the use of mobile technology to coach physical activity and monitor emotional wellbeing during one month. Our results show that the participants became more aware of their daily physical activity and perceived an added value in using the technology in daily life. However, only limited added-value was perceived on monitoring positive emotions in daily life in the way we performed it. The most common argument concerned repetitiveness of the questions being asked every day. Moreover, participants also reported that they were not used to think about their emotions, what affected the way they answered the questions regarding their emotional wellbeing. Our results suggest that, to ensure reliability of the data, it is extremely important to hear the experience of the participants after performing studies in daily life.

SICOBIO - Consolidation and Analysis System of Biomedical Information

Authors:

William Enrique Parra Alba and Alexandra Pomares Quimbaya

Abstract: Improving information systems and guaranteeing the quality of health services are current challenges for global governments. Financing problems and congestion in health care centers, increased demand for services due to aging population, mobility issues and insecurity, risks of accidents and contagion of diseases in care centers are some of the problems to be solved. In order to reduce these problems, it is necessary to take advantage of technological advances to give alternative solutions. This paper presents SICOBIO, a system for monitoring patients who finish their treatment at home, and facilitates the integration of devices and analysis algorithms. The information from remote sensors is homogenized, consolidated, and analyzed in a synchronous and asynchronous manner. Through synchronous analysis, the patient's risk is assessed and alerts are generated to his caregivers, and through asynchronous analysis, decision-making is supported with statistical and data mining techniques applied to historical information. SICOBIO was validated with devices for remote monitoring of physical activity, heart rate and weight. It demonstrated its scalability to incorporate new equipment and new algorithms of analysis and delivery of alerts. Its potential utility was validated through the Technology Acceptance Model (TAM).

Authors:

Inés Pinilla Giménez, Francisco J. Díaz-Pernas, Sonia Garrote Fernández, Juan Azael Herrero Alonso, David González Ortega and Mario Martínez-Zarzuela

Abstract: In this paper we describe the features of a serious game with virtual reality for use as a complement in rehabilitation therapies for patients who have suffered a stroke with subsequent motor and/or cognitive sequelae. We will expose the importance of rehabilitation in this kind of patients, and how virtual reality video games can be a good complement to the classical rehabilitation method. The game is divided in two applications: one for the therapists where they can change the parameters of the game for adapting it to the patient’s limitations, and the user’s application where the patient can play the different scenes and can perform the prescribed rehabilitation exercises. Each one of the scenes allows the patient to perform some movements aimed at the rehabilitation of some of its limitations, both motor and cognitive.

Authors:

Raúl Velasco Caminero, Luis A. Méndez-Herrero, Francisco J. Díaz-Pernas, Juan Calabia del Campo, Míriam Antón Rodríguez and Mario Martínez-Zarzuela

Abstract: In this paper we describe a virtual rehabilitation system designed to improve different physical and cognitive disorders. Rehabilitation is carried out through virtual reality and serious games. Currently, in this system, we use Microsoft Kinect v2 and Leap Motion sensors. Thanks to the modular development of the system, we can add new rehabilitation devices such as Oculus Rift, as well as create new games depending on the pathology to be treated. Therapists access to the system through a web portal where, depending on their access level, they can create rehabilitation sessions and therapies and track the patients’ progress. Patients access to the system through a local application and not using keyboard or mouse devices, using a natural user interface based on their movements. Rehabilitation sessions consist on serious games where the patient performs the exercises of his session programmed by a therapist. There are different types of user with different access levels: administrator, therapist, familiar and patient. The different types of user interact with their respective modules.

Information Needs about Public and Social Services of Portuguese Elderly

Authors:

Telmo Silva, Hilma Caravau and David Campelo

Abstract: In a society increasingly attentive to the problems faced by seniors it is essential to promote their independence and autonomy. Providing these citizens with adequate information to support daily decision making processes and to be alert about situations of disadvantage and inequality is a concern of several entities seeking to promote elderly empowerment. A number of gerontechnologies aimed to "add quality years to life" have appeared to stimulate healthy, active and independent life. In line with this, it is being developed the +TV4E interactive TV platform, which aims to promote the info-inclusion of Portuguese seniors through the exhibition of informative contents about public and social services on TV. This paper aims to assess the public and social services Portuguese seniors feel most in need to access information about. Findings of this exploratory study showed that the information needs of elderly are organized in the following macro-areas: health care and welfare services; social services; financial services; culture, informal; education and entertainment; security services; local authority services; and transport services.

Technology as an Area of Conflict between Autonomy and Safety - Acceptance and Attitudes of Family Caregivers in Regard to Technical Assistance to Ensure Safe Areas of Movement for People with Dementia Diseases

Authors:

Irene Müller, Matthias Mertin and Rolf M.A.

Abstract: Family caregivers take on a responsible task when caring for people with dementia showing the phenomenon of wandering. Technical systems like Global Positioning Systems (GPS) could support them in this respect. So far, there are no empirical studies in the German-speaking area that illustrate the attitude and acceptance of family caregivers on this subject. The subjective perspective of the family caregivers has now been ascertained after a systematic literature review and the selection of a qualitative research design based on n=14 problem-centered interviews. As a result, family caregivers endorse the use of technical devices to ensure safe areas of movement for people with dementia in cases where the benefit is recognizable and the handling is uncomplicated. Ethical questions are a major challenge for family caregivers as they have to make decisions for people with dementia that conflicts with autonomy and safety.

PERCEPT Indoor Wayfinding for Blind and Visually Impaired Users: Navigation Instructions Algorithm and Validation Framework

Authors:

Yang Tao, Linlin Ding, Sili Wang and Aura Ganz

Abstract: This paper introduces an algorithm that generates indoor navigation instructions for Blind and Visually Impaired (BVI) users as well as a validation framework that validates these instructions. The validation framework which utilizes Unity game engine incorporates: a) a virtual environment that mirrors the physical environment and b) a game avatar that traverses this virtual environment following action code sequences which correspond to the navigation instructions. A navigation instruction from a source to a destination is correct if the game avatar successfully reaches from the source to the destination in the virtual environment following this navigation instruction. We successfully tested the navigation instruction generation algorithm and the validation framework in a large two-story building with 66 landmarks and 1500 navigation instructions. To the best of our knowledge this is the first automated generation instructions algorithm for BVI users in indoor environments, and the first validation framework for navigation instructions in indoor environments. This paper is a significant step towards the development of a cost effective indoor wayfinding solution for BVI users.

Abstract: In much of the world, particularly the developed world, there’s a growing aging population. Our work focuses on user experience and its impact on user interface design of web-based applications for elderly people. The paper presents the set of aging-centered user interface design guidelines. An initial collection of guidelines was first developed through an extensive review of the human-computer interaction and aging-oriented literature and through applying a series of classification methods. Then the Authors proposed an assessment framework, which could be used as an universal tool to evaluate the web-based system according the user interfaces dedicated for elderly people. The detailed guidelines were grouped into 7 categories which were granted with appropriate importance weights. In the next section ActGo-Gate platform was presented as a web-based application dedicated for activating and supporting elderly people. Finally, the user interface of the system was evaluated according the proposed criteria.

SousChef: Mobile Meal Recommender System for Older Adults

Authors:

David Ribeiro, João Machado, Jorge Ribeiro, Maria João M. Vasconcelos, Elsa F. Vieira and Ana Correia de Barros

Abstract: Nowadays, following a healthy diet is a challenge, either due to the large variety of food and ingredient combination possibilities or due to the lack of knowledge required to make healthy choices. This problem is even more patent amongst older adults. Although some recommender systems and applications have been proposed with aim to monitor calorie consumption and/or to suggest healthy recipes to general consumers, no similar solution was yet presented focused on older adults’ needs. In this work, a mobile meal recommender system, SousChef, for this target group is presented. This system is capable of creating a personalized meal plan based on the information provided by the user, including the anthropometric measures, personal preferences and activity level. The nutritional recommendations and the application was thought and designed for older adults, presenting friendly user interfaces and following the guidelines of a nutritionist. Tests with users were conducted in order to ascertain recipe and nutritional plan suitability as well as usability of the mobile application. Results showed that more than 70% of the older adult participants were satisfied with the meal plan suggestions and with the simplicity of the SousChef application.

Study on Depression Evaluation Indicator in the Elderly using Sensibility Technology

Authors:

Masakazu Higuchi, Shuji Shinohara, Mitsuteru Nakamura, Yasuhiro Omiya, Naoki Hagiwara, Shunji Mitsuyoshi and Shinichi Tokuno

Abstract: Depression is important issue with aging of global population. Previously we have proposed a method to evaluate the mental health status of a person by his or her voice and developed a smartphone-based system to monitor mental health from voice during a call. Although the system has excellent continuous monitoring capability, it has not enough specificity for screening. Therefore, in this study we propose an evaluation indicator to assess depression status in the elderly, based on multivariate analysis using the emotional components of the voice data collected in the aforementioned system and the BDI score. The voice emotion data on subjects was divided into two groups according to BDI score, one where doctor's diagnosis was deemed necessary and the other not so. A significant difference between the two groups was observed in t-test when the mean of the evaluation indicator estimated using data of each group and applying logistic regression prediction equation was compared. Moreover, a performance corresponding to AUC of approximately 0.75 was achieved in the ROC curve of the derived evaluation indicator. The results suggest that a new method to evaluate depression using voice has likely been developed.

A Multi-perspective View on AAL Stakeholders’ Needs - A User-centred Requirement Analysis for the Activeadvice European Project

Authors:

Soraia Teles, Diotima Bertel, Andrea Ch. Kofler, Stefan H. Ruscher and Constança Paúl

Abstract: This paper discusses the process of including a multi-perspective view on stakeholders’ needs into a specific project, namely the European project ActiveAdvice. It highlights the factors supporting and hindering the development and the implementation of the ActiveAdvice platform – as an integrated communication tool targeted at bridging the gaps between AAL stakeholders by facilitating cooperation and information exchange – regarding user requirements, preferences, acceptances and expectations. For this, a qualitative study was carried out, taking into account not only the older adults as primary end-users but the whole AAL stakeholder ecosystem. 23 semi-structured interviews with stakeholders of different groups – older adults and their relatives, business as well as government representatives – were conducted. The results show that even though different stakeholders can have conflicting needs, e.g. regarding online communication or feedback, those can be integrated into the requirements analysis, thus including the whole stakeholder ecosystem in the designing process. Furthermore, all three included stakeholder groups agree on the importance of raising awareness of AAL solutions, technologies and products. In including not only consumers but other secondary and tertiary stakeholders as well, ActiveAdvice has the chance to reach a broader audience and thus raise public awareness of AAL.

Recognizing Sleep Stages with Wearable Sensors in Everyday Settings

Authors:

Ulrich Reimer, Sandro Emmenegger, Edith Maier, Zhongxing Zhang and Ramin Khatami

Abstract: The paper presents results from the SmartSleep project which aims at developing a smartphone app that gives users individual advice on how to change their behaviour to improve their sleep. The advice is generated by identifying correlations between behaviour during the day and sleep architecture. To this end, the project addresses two sub-tasks: detecting a user’s daytime behaviour and recognising sleep stages in an everyday setting. The focus of the paper is on the second task. Various sensor devices from the consumer market were used in addition to the usual PSG sensors in a sleep lab. An expert assigned a sleep stage for every 30 seconds. Subsequently, a sleep stage classifier was learned from the resulting sensor data streams segmented into labelled sleep stages of 30 seconds each. Apart from handcrafted features we also experimented with unsupervised feature learning based on the deep learning paradigm. Our best results for correctly classified sleep stages are in the range of 90 to 91% for Wake, REM and N3, while the best recognition rate for N2 is 83%. The classification results for N1 turned out to be much worse, N1 being mostly confused with N2.
