H. J. Toh, Chia J., E. Koh, K. Lam, G. C. Magpantay, C. M. De Leon and J. A. Low

Abstract: Geriatric specialists have been scarce in Singapore and this has drawn attention to a rising need in providing quality care for the ageing society. Access to geriatric care could decrease nursing home to acute hospital transfers, thus improving residents’ quality of life. A pilot project implemented by an acute hospital in Singapore aims to use videoconferencing systems to improve access to geriatric specialist care for nursing homes and thereby reduce unnecessary acute hospital admissions. We aim to assess the impact of the level of engagement with Telegeriatrics has on nursing home to hospital transfer rates. Two nursing homes were recruited from December 2010 to March 2014. A total of 379 telemedicine consultation episodes were conducted over this period. Hospital admission rates were monitored over a 2-year period and compared against the nursing home’s level of engagement with Telegeriatrics. The more-engaged nursing home reported a significant decrease of 29% in hospital admission rates. In contrast, the less-engaged nursing home only reported a 6% decrease. The findings show a reduction in hospital admission rate for both nursing homes. When the two nursing homes were compared, the nursing home that was more engaged with Telegeriatrics had a lower rate of unnecessary hospital admission. Telegeriatrics has the potential to reduce unnecessary hospitalisation frequently experienced by nursing home residents. Furthermore, a decrease in hospital readmission rates enables hospital beds to be better utilised, reduces medical spending and relieves residents’ distress.

H. J. Toh, J. Chia, E. Koh, K. Lam, G. C. Magpantay, C. M. De Leon and J. A. Low

Abstract: Geriatric care is a holistic approach to caring for older persons with complex health problems, so as to meet their long term care needs and maintain their independence for as long as possible. Due to a scarcity of geriatricians, Telegeriatrics was piloted in December 2010 by an acute hospital in Singapore to improve access to geriatric specialists for nursing homes. This preliminary study explores the perspectives of users from the NHs and the acute hospital on two aspects of Telegeriatrics – the telemedicine consultation and the nurse training programme. Seven focus group discussions and two semi-structured moderate interviews were conducted with a total of 24 participants. Thematic content analysis was applied to identify important themes and new themes that emerged during the coding process. The most commonly recognised benefits were increased access to specialist care, reduced need for hospitalizations, improved quality of care, and enhanced nursing skills and knowledge. However, the greatest barriers as perceived by the users were the lack of personal touch, technical issues, and medico-legal issues. The users expressed general acceptance of Telegeriatrics in providing geriatric care. They were aware of its limitations and challenges, but also recognized it as a promising way of providing consultation and strengthening nursing skills.

Improving Activity Monitoring Through a Hierarchical Approach

Authors:

Xavier Rafael-Palou, Eloisa Vargiu, Guillem Serra and Felip Miralles

Abstract: Performance of sensor-based telemonitoring and home support systems depends, among other characteristics, on the reliability of the adopted sensors. Although binary sensors are quite used in the literature and also in commercial solutions to identify user’s activities, they are prone to noise and errors. In this paper, we present a hierarchical approach, based on machine learning techniques, aimed at reducing error from the sensors. The proposed approach is aimed at improving the classification accuracy in detecting if a user is at home, away, alone or with some visits. It has been integrated in a sensor-based telemonitoring and home support system. Results show an overall improvement of 15% in accuracy with respect to a rule-based approach. The system is part of the BackHome project and is currently running in 2-healthy-users’ home in Barcelona and in 3-end-users’ home in Belfast.

On Modeling the Cardiovascular System and Predicting the Human Heart Rate under Strain

Authors:

Melanie Ludwig, Ashok Meenakshi Sundaram, Matthias Füller, Alexander Asteroth and Erwin Prassler

Abstract: With the increasing average age of the population in many developed countries, afflictions like cardiovascular diseases have also increased. Exercising has a proven therapeutic effect on the cardiovascular system and can counteract this development. To avoid overstrain, determining an optimal training dose is crucial. In previous research, heart rate has been shown to be a good measure for cardiovascular behavior. Hence, prediction of the heart rate from work load information is an essential part in models used for training control. Most heart-rate-based models are described in the context of specific scenarios, and have been evaluated on unique datasets only. In this paper, we conduct a joint evaluation of existing approaches to model the cardiovascular system under a certain strain, and compare their predictive performance. For this purpose, we investigated some analytical models as well as some machine learning approaches in two scenarios: prediction over a certain time horizon into the future, and estimation of the relation between work load and heart rate over a whole training session.

BigTexts - A Framework for the Analysis of Electronic Health Record Narrative Texts based on Big Data Technologies

Authors:

Wilson Alzate Calderón, Alexandra Pomares Quimbaya, Rafael A. Gonzalez and Oscar Mauricio Muñoz

Abstract: In the healthcare domain the analysis of Electronic Medical Records (EMR) may be classified as a Big Data problem since it has the three fundamental characteristics: Volume, Variety and Speed. A major drawback is that most of the information contained in medical records is narrative text, where natural language processing and text mining are key technologies to enhance the utility of medical records for research, analysis and decision support. Among the tasks performed for natural language processing, the most critical, in terms of time consumption, are the pre-processing tasks that give some structure to the original non-structured text. Studying existing research on the use of Big Data techniques in the healthcare domain reveals few practical contributions, especially for EMR analysis. To fill this gap, this paper presents BigTexts, a framework that provides pre-built functionalities for the execution of pre-processing tasks over narrative texts contained in EMR using Big Data techniques. BigTexts enables faster results on EMR narrative text analysis improving decision making in healthcare.

Authors:

René Zmugg, Andreas Braun, Peter Roelofsma, Wolfgang Thaller, Lisette Moeskops, Sven Havemann, Gabrijela Reljic and Dieter W. Fellner

Abstract: Virtual coaching is an application area that allows individuals to improve existing skills or learn new ones; it ranges from simple textual tutoring tools to fully immersive 3D learning situations. The latter aim at improving the learning experience with realistic 3D environments. In highly individual training scenarios it can be beneficial to provide some level of personalization of the environment. This can be supported using procedural modeling that allows to easily modify shape, look and contents of an environment. We present the application of personalization using procedural modeling in learning applications in the project V2me. This project combines virtual and social networks to help senior citizens maintain and create meaningful relationships. We present a system that uses a procedurally generated ambient virtual coaching environment that can be adjusted by training subjects themselves or in collaboration. A small user experience study has been executed that gives first insight to the acceptance of such an approach.

Authors:

Flavio Corradini, Francesco De Angelis, Barbara Re, Emiliano Anceschi, Massimo Callisto De Donato and Paolo Iddas

Abstract: A Private Assisted House aims to define a novel care model focusing on the changing needs of people to promote active life expectancy. This raises the need of personalization in the design and development of Smart Home, so starting from users requirements we stress the need of integration suitable to support such changing requirements. In this paper we discuss Private Assisted House integration platform focusing on its conceptual model and reference architecture. The platform is defined around a set of smart objects managed by a home gateway that communicate with a Cloud Center. This organization provide two kinds of processing: (i) local to the house, and (ii) remote. The local processing involves events, triggers, commands and automations managed directly for the gateway. The remote processing implies communication from the house to the Cloud Center that can provide intelligence to the house using high-level applications that use data correlation to perform specific tasks.

Authors:

Silvia Macis, Daniela Loi, Danilo Pani, Wil Rijnen and Luigi Raffo

Abstract: The modern society is dealing with a progressive increase of the elderly population. The development of services for social inclusion and independent living is of paramount importance to enable the elderly to live in their homes autonomously as long as possible. Such a solution paves the way to a sustainable social and economic model where older adults develop self-confidence and promote their participation to the community life. This paper presents the hardware/software framework of a novel ICT system for active ageing support, which combines the potentialities of broadband internet services to the simplicity of TV use. User research in three European countries allowed to define several important services (healthcare, home monitoring, shopping, communication and social inclusion) to be provided through the developed platform. Its modularity, supported by the App paradigm, enables easy customization and future developments.

Ageing and Death - Breaking a Taboo

Authors:

Matthias Rauterberg and Kiarash Irandoust

Abstract: This position paper argues for addressing ‘good death’ as part of ‘well ageing’ in human life. Although in most societies death is protected through taboos, we have to provide solutions in helping citizens preparing for their own death. The Oedipus Trilogy is an ancient narrative to describe clearly the three phases in any human life, the unavoidability of those phase changes. We have to use the last phase of our life to prepare for the end. We will summarize the different philosophical positons regarding ‘meaning of life’, and – although addressing death is a mainly social issue – we describe the challenges for future ICT development in supporting the important last steps of preparing for a ‘good death’.

Perception of Human Activities - A Means to Support Connectedness Between the Elderly and Their Caregivers

Authors:

Kadian Davis, Evans Owusu, Carlo Regazzoni, Lucio Marcenaro, Loe Feijs and Jun Hu

Abstract: This position paper describes a smart-phone based activity recognition system for improving social connectedness between caregivers and their elderly relatives. Sensing technologies can enable real-time monitoring to provide activity recognition in order to support health and safety among the elderly who are living independently. However, most existing activity recognition systems are focused on using sensors for unidirectional monitoring of emergency cases in particular, fall detection. Motivated by the desire to utilize bidirectional activity recognition to improve connectedness between an ageing population and their caregivers, we describe our planned approach to investigate how the perception of a caregiver’s activities by a senior citizen and vice versa can aid in improving social connectedness. To investigate this perception, activity states will be transformed into an information visualization into the caregiver’s home and vice versa without overt communication from participants. Findings are expected to provide further insight on the extent to which perception of human activities increase social connectedness.

Unobtrusive Monitoring of Physical Activity in AAL - A Simple Wearable Device Designed for Older Adults

Authors:

Adelmo De Santis, Antonio Del Campo, Ennio Gambi, Laura Montanini, Giovanni Pelliccioni, Davide Perla and Susanna Spinsante

Abstract: Many solutions and projects proposed within the Ambient Assisted Living research area, aim at monitoring the degree of vitality of elderly users in their daily activities, and in their home environment, to possibly avoid or strongly limit the need for clinical evaluations. In fact, the information on the subject’s vitality, manifested through his/her activity profile, may be used to evaluate possible anomalous trends, related to cognitive or physical decay. For such a kind of analysis to be realistically affordable, the monitoring device shall be unobtrusive, and transparent to the user. With the aim of striving for the simplest and most reliable design compatible with the aforementioned requirements, this paper presents a wearable device equipped with a sensing insole hosting force sensors, and the related electronics for signal processing and data transmission. The device locally classifies different dynamic states (sitting, walking, standing) and transmits the corresponding information to a supervising system. Preliminary experimental results confirm the effectiveness of the approach, in correctly detecting and classifying the user’s activities.

Requirements for Relaxation Coaching - A Formalization of the Fogg Behavior Model

Authors:

Rogier M. van Eijk

Abstract: Relaxation training consists of doing regular (e.g., daily) relaxation exercises over a longer period of time (e.g., months). Adherence to relaxation training is for many people difficult because of time constraints, social obligations, forgetting to practice and so on. This is a pity because relaxation training can act as a natural antidote to health-related effects of excessive stress like poor sleep. In this paper, we present a formal model of relaxation coaching that is rooted in the theory of persuasive design. This model supports the development of coaching systems that can improve people’s adherence to relaxation training with its associated health benefits.

Scenario Development for Successful Aeging with Robot Companions

Authors:

Katja Richter and Nicola Döring

Abstract: To illustrate how service-robots for healthcare can support independent living of older people three normative, narrative scenarios were systematically developed. In the sense of a user-centered design, scenarios are a promising opportunity to involve the target groups in the development and implementation process. Each scenario illustrates a different but typical day of an elderly person living with such a robot. Scenarios intend to encourage a lively but focused discussion of future technologies with different target groups. The personas (hypothetical but concrete prototypes of user groups describing specific requirements and usage behavior) were derived from the state-of-the-art concerning the every-day life of older people and the results of a qualitative interview-study focused on the structures and schedules of the seniors’ daily routines. Additionally, key dimensions of the scenario space (specification of service-robots, older people and living environments) as well as descriptors characterizing each dimension, were identified by means of an exhaustive, systematic literature review and consistency analysis. The paper presents the scenario development process, the scenarios and their use in evaluation studies.

A Position Paper Managing Youth Screen Time versus Physical Activity - Encouraging Active Living in a Technological Focussed Generation

Authors:

Reem Altamimi, Keith Nesbitt and Geoff Skinner

Abstract: Childhood obesity is becoming increasingly prolific and problematic. Contributors to childhood obesity include decreased levels of physical activity and increased sedentary behaviour. Screen-based entertainment may be an important factor in the development of childhood obesity as children and adolescents prefer to spend time using electronic devices than exercising. While it is difficult to encourage children to cease playing video games, it is possible to change these passive screens to active ones. Information and Communication Technologies (ICTs) have been utilized by academics and researchers to promote levels of physical activity among young people. This position paper is part of our continuous research into the use of technology in the facilitation and motivation of children to be more physically active. This paper presents the “MySteps” framework that has been developed to manage youth screen time and exercise performance statistics. By developing technology-based solutions, we intend to increase children and adolescents awareness of their levels of physical activity and screen time. Consequently, self-monitoring and management of screen time and physical activity levels may lead to more active living beginning at an early age and continuing in life.

Reliability and Usability of the eChez-Soi In-home Telerehabilitation Platform: A New Internet-based Communication and Real-time Monitoring Software Solution Combined with Interactive Exercises - Results of a Longitudinal Pilot Study in Four Patients with Lung Cancer

Authors:

Hélène Moffet, Didier Saey, Valérie Coats, Claude Vincent, Fanny Choinière and François Comeau

Abstract: This longitudinal pilot study aims to describe the components and functionalities of the eChez-Soi home-based telerehabilitation platform, and present preliminary results on its technological reliability and usability. Four patients receiving chemotherapy treatments for lung cancer followed an 8 week home-based telerehabilitation program using the new eChez-Soi platform. All 60 planned sessions supervised by a clinician occurred with few technological problems. Only one session had to be rescheduled because of unresolved audiovisual communication problems. In 20 sessions, temporary problems were experienced, mostly related to the audiovisual signal (n=16), while few technical problems were associated with the sensors (n=1) and the interactive exercise software (n=1). The usability of the platform was very good, with an overall satisfaction rating of 4.63±0.43 (max. score=5) for all aspects evaluated, namely its dimension, safety, effectiveness, ease of use and game environment. These preliminary results support the reliability and usability of our new platform as a whole but highlight the challenges encountered in ensuring a stable audiovisual signal when delivering services via a standard home-based Internet connection.

Abstract: In this paper we describe a virtual rehabilitation platform designed to improve balance of people with physical impairment using the Microsoft® Kinect® sensor. Different types of users can interact with the platform: Administrators, therapists, and final users (patients), using their own interfaces and modules. Six modules have been designed: Profile, Administrator, Evaluation, Therapist, Game and Results; but only four have been implemented so far: Administrator, Evaluation, Therapist and Game. The Administrator’s module is used to generate a database of exercises. The Therapist’s module allows therapists to configure the game training session using combinations of exercises from the database. The patients’ or game module includes a 3D immersive environment, where they perform the prescribed rehabilitation exercises, previously configured by a therapist. The platform is in its first beta version and ready to be tested.

Multimodal Analysis for Behavioural Recognition in Tele-assistance Applications

Authors:

Sorin Soviany and Sorin Puscoci

Abstract: The paper proposes an approach for behavioural recognition in which the individual conditions are recognized using a multimodal analysis method. This approach is an extension of our previously defined multimodal analysis method for biometrics; in this case the target application is the accurate recognition of human behaviour in smart home environments, with main focus in the home tele-assistance integrated services for elderly people. The proposed multimodal analysis method uses a hierarchical approach for data classification together with a fusion rule to combine the matching scores for several behavioural patterns. The approach novelty is given by the hierarchical classification design which provides an optimal performance-cost trade-off for the behavioural recognition system. This optimization could be done at runtime in practical applications.

Authors:

Nuno Rocha, Raquel Sousa and Gil Gonçalves

Abstract: Ageing of the European population raises issues both socially and economically, creating major challenges for the traditional care and healthcare paradigm. Recent technological developments generate a favorable environment for a paradigm shift in the way care and healthcare is provided, by promoting the inclusion of the elders in the digital society. This paper presents an approach to promote elders inclusion, based on a RWD platform, capable of being used in multiple devices (including SmartTVs), and in wireless sensor networks. Studies involving end users have shown how well-adjusted interfaces ease the process of inclusion of IT in elders’ life. This work has been developed within the frame of the European project HELASCoL.

Reminiscence Map - Insights to Design for People with Dementia from a Tangible Prototype

Authors:

Alina Huldtgren, Anja Vormann and Christian Geiger

Abstract: With higher life expectancy and an increasing number of older people, the number of people suffering from dementia continues to grow. Dementia impacts all areas of daily life and, in particular, communication with other people and maintenance of personhood. Technology is a promising means to address these challenges, yet approaches to design with and for people with dementia remain sparse. In our work we aim specifically to design interactive systems that can be used by people with dementia, e.g., as part of reminiscence therapy or generally to remember the past and communicate with others. In this paper, we present our research and design approach and exemplify one design case: the interactive Reminiscence Map, which was developed together with a person with early stage dementia. We show how this design served us as a lens into life of the care home residents and caregivers and provide design insights.

Interaction Modeling in PRACTICE - CTT Vs. SCXML - A Comparison of Two Practical Solutions Applying Interaction Modeling Techniques for Multimodal User-System Interaction

Authors:

Miroslav Sili, Matthias Gira, Markus Müllner-Rieder and Christopher Mayer

Abstract: Nowadays, we are surrounded by various devices to interact with digital media and services. Each device and its in- and output modalities can support users’ abilities differently. Thus, it is important to cover a wide range of interaction devices. Modeling user interaction instead of modeling single user interfaces customized to the device is a starting point to do so. This work targets the comparison of two different user interaction modeling techniques used for the design of multimodal user interfaces. Next to the general concepts of the two interaction modeling techniques, the corresponding execution frameworks and the practical exploration results are presented. This paper summarizes advantages and disadvantages of each approach and the comparison clarifies that the CTT approach applied in AALuis is more applicable for large and complex user interaction scenarios. The SCXML approach applied in the ibi project is more suitable for lightweight and structurally simpler user interaction scenarios.

The Assistant Project - Creating a Smartphone App to Assist Older People when Travelling by Public Transport

Authors:

Philip Barham, Stefan Carmien and Ainara Garzo

Abstract: This is a Position Paper, in the form of a short report on progress of the three-year ASSISTANT project, which is funded jointly by the European Commission’s Ambient Assisted Living Joint Programme (AAL JP) and the national funding agencies of Austria, Finland, France, Spain and the UK. ASSISTANT’s objective is to create a system that older people can use, on a smartphone, to help them to travel independently by public transport, in comfort and with confidence. The target group for the commercial product that will be developed by the project is more mobile older people. However, because the app will be highly personalised, and provide the user with the facility of audible and haptic, as well as visual, feedback, it should also be appropriate for use by people who are partially sighted, people who are hard of hearing, and people who have difficulty with oral communication. This paper describes progress made during the first two and a half years of the project’s life, and outlines some of the ways in which the ASSISTANT app will be tailored to meet the needs of a variety of users, in a variety of public transport contexts.

Abstract: This study shows preliminary results of the multicenter and international I-DONT-FALL (IDF) project, cofunded by the European Union, aiming to offer an integrated Information and Communication Technologies (ICT) solution for fall prevention and detection. Here we assessed the efficacy of a motor and a cognitive treatment delivered through the IDF ICT solution, aiming to reduce the risk of falls through a randomized controlled trial. The outcome was measured with the Falls Efficacy Scale-International (FES-I) and the subscales of the Tinetti Performance Oriented Mobility Assessment for balance (POMA-B) and gait (POMA-G). We compared the effect of a 24-sessions period of motor training delivered through an i-Walker vs. a comparable period of non-motor training in terms of frequency and duration of sessions. The same comparison was performed for a period of cognitive training delivered though a touch-screen computer interface vs. a comparable period of non-cognitive training in terms of frequency and duration of sessions. Results showed that motor treatment alone or mixed with cognitive training reduces significantly the fear of falling and the risk of falls. Both cognitive and motor treatments showed a nonspecific positive effect on balance performance of participants. These preliminary results are consistent with previous evidences.
