    An Evaluation Tool of the Effect of Robots in Eldercare on the Sense of Safety and Security2017Ingår i: Social Robotics: 9th International Conference, ICSR 2017, Tsukuba, Japan, November 22-24, 2017, Proceedings / [ed] Kheddar, A.; Yoshida, E.; Ge, S.S.; Suzuki, K.; Cabibihan, J-J:, Eyssel, F:, He, H., Springer International Publishing , 2017, s. 628-637Konferensbidrag (Refereegranskat)
    Abstract [en]

    The aim of the study presented in this paper is to develop a quantitative evaluation tool of the sense of safety and security for robots in eldercare. By investigating the literature on measurement of safety and security in human-robot interaction, we propose new evaluation tools. These tools are semantic differential scale questionnaires. In experimental validation, we used the Pepper robot, programmed in the way to exhibit social behaviors, and constructed four experimental conditions varying the degree of the robot’s non-verbal behaviors from no gestures at all to full head and hand movements. The experimental results suggest that both questionnaires (for the sense of safety and the sense of security) have good internal consistency.

    The Relevance of Social Cues in Assistive Training with a Social Robot2018Ingår i: 10th International Conference on Social Robotics, ICSR 2018, Proceedings / [ed] Ge, S.S., Cabibihan, J.-J., Salichs, M.A., Broadbent, E., He, H., Wagner, A., Castro-González, Á., Springer , 2018, s. 462-471Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper examines whether social cues, such as facial expressions, can be used to adapt and tailor a robot-assisted training in order to maximize performance and comfort. Specifically, this paper serves as a basis in determining whether key facial signals, including emotions and facial actions, are common among participants during a physical and cognitive training scenario. In the experiment, participants performed basic arm exercises with a social robot as a guide. We extracted facial features from video recordings of participants and applied a recursive feature elimination algorithm to select a subset of discriminating facial features. These features are correlated with the performance of the user and the level of difficulty of the exercises. The long-term aim of this work, building upon the work presented here, is to develop an algorithm that can eventually be used in robot-assisted training to allow a robot to tailor a training program based on the physical capabilities as well as the social cues of the users.

    Evaluating the Sense of Safety and Security in Human–Robot Interaction with Older People2019Ingår i: Social Robots: Technological, Societal and Ethical Aspects of Human-Robot Interaction / [ed] Oliver Korn, Springer, Cham , 2019, s. 237-264Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    For many applications where interaction between robots and older people takes place, safety and security are key dimensions to consider. ‘Safety’ refers to a perceived threat of physical harm, whereas ‘security’ is a broad term which refers to many aspects related to health, well-being, and aging. This chapter presents a quantitative evaluation tool of the sense of safety and security for robots in elder care. By investigating the literature on measurement of safety and security in human–robot interaction, we propose new evaluation tools specially tailored to assess interaction between robots and older people.

    An Ontology-based Context-aware System for Smart Homes: E-care@home2017Ingår i: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 17, nr 7, artikel-id 1586Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Smart home environments have a significant potential to provide for long-term monitoring of users with special needs in order to promote the possibility to age at home. Such environments are typically equipped with a number of heterogeneous sensors that monitor both health and environmental parameters. This paper presents a framework called E-care@home, consisting of an IoT infrastructure, which provides information with an unambiguous, shared meaning across IoT devices, end-users, relatives, health and care professionals and organizations. We focus on integrating measurements gathered from heterogeneous sources by using ontologies in order to enable semantic interpretation of events and context awareness. Activities are deduced using an incremental answer set solver for stream reasoning. The paper demonstrates the proposed framework using an instantiation of a smart environment that is able to perform context recognition based on the activities and the events occurring in the home.

    Towards a methodology for longitudinal evaluation of social robotic telepresence for elderly2011Ingår i: 1st Workshop on Social Robotic Telepresence at HRI 2011, 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper describes a methodology for performing longitudinal evaluations when a social robotic telepresence system is deployed in realistic environments. This work is the core of an Ambient Assisted Living Project called ExCITE, Enabling Social Interaction Through Telepresence. The ExCITE project is geared towards an elderly audience and has as aim to increase social interaction among elderly, their family and healthcare services by using robotic telepresence. The robotic system used in the project is called the Giraff robot and over a three year period, prototypes of this platform are deployed at a number of test-sites in different European countries where user feedback is collected and fedback into the refinement of the prototype. In this paper, we discuss the methodology of ExCITE in particular relation to other methodologies for longitudinal evaluation. The paper also provides a discussion of the possible pitfalls and risks in performing longitudinal studies of this nature particularly as they relate to social robotic telepresence technologies.

    Combining Semi-autonomous Navigation with Manned Behaviour in a Cooperative Driving System for Mobile Robotic Telepresence2015Ingår i: COMPUTER VISION - ECCV 2014 WORKSHOPS, PT IV, Berlin: Springer Berlin/Heidelberg , 2015, s. 17-28Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents an image-based cooperative driving system for telepresence robot, which allows safe operation in indoor environments and is meant to minimize the burden on novice users operating the robot. The paper focuses on one emerging telepresence robot, namely, mobile remote presence systems for social interaction. Such systems brings new opportunities for applications in healthcare and elderly care by allowing caregivers to communicate with patients and elderly from remote locations. However, using such systems can be a difficult task particularly for caregivers without proper training. The paper presents a first implementation of a vision-based cooperative driving enhancement to a telepresence robot. A preliminary evaluation in the laboratory environment is presented.

    The Effect of Field of View on Social Interaction in Mobile Robotic Telepresence Systems2014Ingår i: Proceedings of the 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI 2014), IEEE conference proceedings , 2014, s. 214-215Konferensbidrag (Refereegranskat)
    Abstract [en]

    One goal of mobile robotic telepresence for social interaction is to design robotic units that are easy to operate for novice users and promote good interaction between people. This paper presents an exploratory study on the effect of camera orientation and field of view on the interaction between a remote and local user. Our findings suggest that limiting the width of the field of view can lead to better interaction quality as it encourages remote users to orient the robot towards local users.

    Evaluation of using semi-autonomy features in mobile robotic telepresence systems2015Ingår i: Proceedings of the 2015 7th IEEE International Conference on Cybernetics and Intelligent Systems, CIS 2015 and Robotics, Automation and Mechatronics, RAM 2015, New York, USA: IEEE conference proceedings , 2015, s. 147-152Konferensbidrag (Refereegranskat)
    Abstract [en]

    Mobile robotic telepresence systems used for social interaction scenarios require that users steer robots in a remote environment. As a consequence, a heavy workload can be put on users if they are unfamiliar with using robotic telepresence units. One way to lessen this workload is to automate certain operations performed during a telepresence session in order to assist remote drivers in navigating the robot in new environments. Such operations include autonomous robot localization and navigation to certain points in the home and automatic docking of the robot to the charging station. In this paper we describe the implementation of such autonomous features along with user evaluation study. The evaluation scenario is focused on the first experience on using the system by novice users. Importantly, that the scenario taken in this study assumed that participants have as little as possible prior information about the system. Four different use-cases were identified from the user behaviour analysis.

    Semi-Autonomous Cooperative Driving for Mobile Robotic Telepresence Systems2014Ingår i: Proceedings of the 9th ACM/IEEE International Conference on Human-Robot Interaction (HRI 2014), IEEE conference proceedings , 2014, s. 104-104Konferensbidrag (Refereegranskat)
    Abstract [en]

    Mobile robotic telepresence (MRP) has been introduced to allow communication from remote locations. Modern MRP systems offer rich capabilities for human-human interactions. However, simply driving a telepresence robot can become a burden especially for novice users, leaving no room for interaction at all. In this video we introduce a project which aims to incorporate advanced robotic algorithms into manned telepresence robots in a natural way to allow human-robot cooperation for safe driving. It also shows a very first implementation of cooperative driving based on extracting a safe drivable area in real time using the image stream received from the robot.

    Auditory immersion with stereo sound in a mobile robotic telepresence system2015Ingår i: 10th ACM/IEEE International Conference on Human-Robot Interaction, 2015, Association for Computing Machinery (ACM) , 2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Auditory immersion plays a significant role in generating a good feeling of presence for users driving a telepresence robot. In this paper, one of the key characteristics of auditory immersion - sound source localization (SSL) - is studied from the perspective of those who operate telepresence robots from remote locations. A prototype which is capable of delivering soundscape to the user through Interaural Time Difference (ITD) and Interaural Level Difference (ILD) using the ORTF stereo recording technique was developed. The prototype was evaluated in an experiment and the results suggest that the developed method is sufficient for sound source localization tasks.

    Privacy by Design Principles in Design of New Generation Cognitive Assistive Technologies2016Ingår i: ICT systems security and privacy protection: 31th IFIP TC 11 International Conference, SEC 2016, Hamburg, Germany, May 30-June 1, 2016, Proceedings / [ed] Jaap-Henk Hoepman & Stefan Katzenbeisser, Springer , 2016, s. 384-397Konferensbidrag (Refereegranskat)
    Abstract [en]

    Today, simple analogue assistive technologies are transformed into complex and sophisticated sensor networks. This raises many new privacy issues that need to be considered. In this paper, we investigate how this new generation of assistive technology incorporates Privacy by Design (PbD) principles. The research is conducted as a case study where we use PbD principles as an analytical lens to investigate the design of the new generation of digitalized assistive technology as well as the users’ privacy preferences that arise in use of this technology in real homes. Based on the findings from the case study, we present guidelines for building in privacy in new generations of assistive technologies and in this way protect the privacy of the people using these technologies.

    Measuring the quality of interaction in mobile robotic telepresence systems using presence, spatial formations  and sociometry2013Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    A mobile robotic telepresence (MRP) system is characterized by a video conferencing system which is mounted on a mobile robotic base. The system allows remote pilot users to move the robot around while communicating with local users situated in the robot’s environment. One of the most promising application areas for MRP systems is to deploy them in homes of elderly who are in frequent contact with health care professionals and/or alarm operators. Using MRP systems, elderly can get in immediate contact with these services even without leaving their homes. However, this poses some challenges for the health care professionals and alarm operators. The alarm operators traditionally communicate with their clients using the telephone while the health care professionals see their patients face-to-face with little interference of computer applications. The encounters between health care professionals and patients typically take place at clinics. Neither the health care professionals nor the alarm operators visit the elderly in person. Accordingly, they have no knowledge about the layout of the homes or where the elderly may reside. Thus, the social communication between them and the elderly via MRP systems is more complex than their traditional interaction with elderly.

    This compilation thesis makes a contribution towards understanding how interaction is affected by MRP system embodiment. The work focuses on measuring quality of interaction in MRP systems deployed in domestic settings in elder care. The thesis proposes a set of useful tools for measuring interaction quality. These tools are presence, spatial formations and sociometry. They were selected based on their ability to capture important characteristics for communication via MRP systems, e.g. social communication and mobility, and have been evaluated in experiments with real end-users, that is with alarm operators, health care professionals and elderly. The tools used to conduct the experimental evaluations of MRP systems include video-based evaluations, driving sessions and retrospective interviews. These methods were carefully chosen and take into consideration the organizational background of the participants involved and the challenge of conducting experiments with the aforementioned groups of users.

    Abstract [en]

    The use of video mediated communication technologies for interacting is increasing. An extension of these is mobile robotic telepresence (MRP) systems, video conferencing systems mounted on teleoperated mobile robots. The nature of the interaction via an MRP system is more complex than face-to-face interaction and involves not only social communication but also mobility. This research focuses on the use of MRP systems in domestic settings in elder care and contributes to the understanding of how interaction is affected by MRP system embodiment.

    A review of mobile robotic telepresence2013Ingår i: Advances in Human-Computer Interaction, ISSN 1687-5893, E-ISSN 1687-5907, Vol. 2013, s. 902316-Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Mobile Robotic Telepresence (MRP) systems incorporate video conferencing equipment onto mobile robot devices which can be steered from remote locations. These systems, which are primarily used in the context of promoting social interaction between people, are becoming increasingly popular within certain application domains such as health care environments, independent living for the elderly and office environments. In this review, an overview of the various systems, application areas and challenges found in literature concerning mobile robotic telepresence is provided. The survey also proposes a set terminology for the field as there is currently a lack of standard terms for the different concepts related to MRP systems. Further, this review provides an outlook on the various research directions for developing and enhancing mobile robotic telepresence systems per se, as well as evaluating the interaction in laboratory and field settings. Finally, the survey outlines a number of design implications for the future of mobile robotic telepresence systems for social interaction.

    Towards evaluation of social robotic telepresence based on measures of social and spatial presence2011Ingår i: 1st Workshop on Social Robotic Telepresence held at HRI 2011, 2011Konferensbidrag (Refereegranskat)
    Abstract [en]

    In this paper we present data collected at a training session for health care personnel and alarm operators in steering a mobile social robotic telepresence robot for the first time. The purpose of the system is to be used as a communicative tool particularly when interacting with an elderly audience. The results are based on questionnaires which includes questions about experienced social and spatial presence from the Temple Presence Inventory as well as the Networked Minds Social Presence Inventory. Also investigated in this study is how intuitive the system was to use as well as how attentive the users were to what was going on in the environment. Over thirty healthcare personnel and alarm operators participated in the study and the overall results presented in the paper suggest that the two questionnaires are indeed suitable for use also in the social robotic telepresence domain fo rproviding indications on both social and spatial presence.

    An exploratory study of health professionals' attitudes about robotic telepresence technology2011Ingår i: Journal of technology in human services, ISSN 1522-8835, E-ISSN 1522-8991, Vol. 29, nr 4, s. 263-283Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This article presents the results from a video-based evaluation study of a social robotic telepresence solution for elderly. The evaluated system is a mobile teleoperated robot called Giraff that allows caregivers to virtually enter a home and conduct a natural visit just as if they were physically there. The evaluation focuses on the perspectives from primary healthcare organizations and collects the feedback from different categories of health professionals. The evaluation included 150 participants and yielded unexpected results with respect to the acceptance of the Giraff system. In particular, greater exposure to technology did not necessarily increase acceptance and large variances occurred between the categories of health professionals. In addition to outlining the results, this study provides a number of indications with respect to increasing acceptance for technology for elderly.

    Assessment of interaction quality in mobile robotic telepresence: an elderly perspective2014Ingår i: Interaction Studies: Social Behaviour and Communication in Biological and Artificial Systems, ISSN 1572-0373, E-ISSN 1572-0381, Vol. 15, nr 2, s. 343-357Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In this paper, we focus on spatial formations when interacting via mobile robotic telepresence (MRP) systems. Previous research has found that those who used a MRP system to make a remote visit (pilot users) tended to use different spatial formations from what is typical in human-human interaction. In this paper, we present the results of a study where a pilot user interacted with ten elderly via a MRP system. Intentional deviations from known accepted spatial formations were made in order to study their effect on interaction quality from the local user perspective. Using a retrospective interviews technique, the elderly commented on the interaction and confirmed the importance of adhering to acceptable spatial configurations. The results show that there is a mismatch between pilot user behaviour and local user preference and that it is important to evaluate a MRP system from two perspectives, the pilot user’s and the local user’s.

    Towards measuring quality of interaction in mobile robotic telepresence using sociometric badges2013Ingår i: Paladyn - Journal of Behavioral Robotics, ISSN 2080-9778, E-ISSN 2081-4836, Vol. 4, nr 1, s. 34-48Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The field of mobile robotic telepresence for social communication is in rapid expansion and it is of interest to understand what promotes good interaction. In this paper, we present the results of an experiment where novice users working in health care were given a guided tour while maneuvering a mobile robotic telepresence system for the first time. In a previous study, it was found that subjective presence questionnaires and observations of spatial configurations based on Kendon’s F-formations were useful to evaluate quality of interaction in mobile robotic telepresence. In an effort to find more automated methods to assess the quality of interaction, the study in this paper used the same measures, with the addition of objective sociometric measures. Experimental results show that the quantitative analysis of the sociometric data correlates with a number of parameters gathered via qualitative analysis, e.g. different dimensions of presence and observed problems in maneuvering the robot.

    Sense of presence in a robotic telepresence domain2011Ingår i: Universal access in human-computer interaction: users diversity, PT 2, Springer , 2011, s. 479-487Konferensbidrag (Refereegranskat)
    Abstract [en]

    Robotic telepresence offers a means to connect to a remote location via traditional telepresence with the added value of moving and actuating in that location. Recently, there has been a growing focus on the use of robotic telepresence to enhance social interaction among elderly. However for such technology to be accepted it is likely that the experienced presence when using such a system will be important. In this paper, we present results obtained from a training session with a robotic telepresence system when used for the first time by healthcare personnel. The study was quantitative and based on two standard questionnaires used for presence namely, the Temple Presence Inventory (TPI) and the Networked Minds Social Presence Intentory. The study showed that overall the sense of social richness as perceived by the users was high. The users also had a realistic feeling regarding their spatial presence.

    Assessment of Expectations and Needs of a Sensor Network to Promote Elderly’s Sense of Safety and Security2014Ingår i: CENTRIC 2014, The Seventh International Conference on Advances in Human-oriented and Personalized Mechanisms, Technologies, and Services, Nice, October 12-16, 2014 / [ed] Lasse Berntzen, Vestfold University College - Tønsberg, Norway; Stephan Böhm, RheinMain University of Applied Sciences - Wiesbaden, Germany, International Academy, Research and Industry Association (IARIA) , 2014, s. 22-28Konferensbidrag (Refereegranskat)
    Abstract [en]

    Many new technologies claiming to support independent living and prolonged possibilities of aging in place have been developed. To support independent living and increase the sense of safety and security both for the elderly themselves and for their relatives, the technologies have to be easily adaptable to match the divergent user’s personal expectations and needs. The study reported in this paper was conducted as seven case studies where a sensor network was deployed in homes of people with a self-perceived memory decline. We describe problems related to adaptive personalization of such technology in real settings and discuss what consequences these problems may have for the elderly people's and their relatives willingness to use the technology. Our results indicate that a lack of sufficient possibilities to adaptive personalization of the system makes it difficult to address individual user's expectations and needs. This, in turn, leads to a decreased trustworthiness of the technology and a risk of unwillingness to use the technology.

    Summative evaluation of a sensor-based cognitive assistive technology: Impact on quality of life and perceived utility2019Ingår i: Gerontechnology, ISSN 1569-1101, E-ISSN 1569-111X, Vol. 18, nr 2, s. 59-69Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Current research shows that perceived improvement of quality of life (QoL) is among the most important factors influencing acceptance of technology by older adults. Research Aim/question(s) The purpose of this study was to assess the utility of a sensor-based cognitive assistive technology (CAT) deployed in real homes and its impact on older adults’ and their informal caregivers’ perceived QoL. Methods During a period of five months, we conducted a summative evaluation by deploying a CAT in the home of couples in which one of the partners had a self-perceived memory decline. We applied a mixed method approach. Quantitative and qualitative data was collected via subjective forms, observations and 28 interviews conducted prior to the deployment, when the CAT was deployed and one month after the CAT removal. Results The study showed that the CAT had a psychosocial impact on older adults with a self-perceived memory decline and their informal caregivers but no impact on subjective forms measuring physiological and mental health, anxiety, depression or QoL. Additionally, we found that the CAT lacked a number of functionalities and that the test persons experienced several problems of different nature when using it in their homes. This affected the users’ experienced impact of the CAT. Conclusions This study contributes to the literature on sensor networks’ impact on QoL. While previous studies often use general forms intended to assess QoL, this summative evaluation indicates that using such instruments without considering contextual factors is not meaningful. The study also outlines a number of factors that sensor network providers might consider in order to increase their products impact on QoL and their perceived utility.

    Understanding users of a future E-care@home system: E-care@home project2017Rapport (Övrigt vetenskapligt)
    Abstract [en]

    This technical report contains personas based on the authors’ earlier and ongoing research together with literature studies. The original aim of the work presented in this report was to provide the E-care@home research environment with an understanding of who the user of a hypothetical future E-care@home system is. The resulting personas are to be used as a tool to aid other work packages within the E-care@home research environment in their design processes. The project focuses on technological solutions and uses artificial intelligence for creating a semantic interoperability between sensor data, systems and humans. The release of this report is, however, a result of several requests of data and user specifications coming from both researchers and companies, who want to base their work on realistic situations of elderly people.

    Several interviews have been performed with potential end users: with healthcare providers within geriatrics care at a hospital, within home care services, and with more-or-less-healthy elderly people, focusing on frail elderly people who may be in risk of falling, developing malnutrition and/or pressure ulcers, and also their closest relatives and their caregivers.

    In this report, 15 personas are presented. There are five different elderly personas. Two of them live together with their spouses, one of which is presented as a persona. In addition, the report presents the personas of eight healthcare professionals, all of which are involved in Senior Alert risk assessments and prevention of falls, malnutrition and pressure ulcers. Three personas represent different professions working in the home care services, the other five personas work at a geriatrics hospital ward. Finally, one informal caregiver of an elderly, a daughter, is presented as a persona. These hypothetical and archetypical users shed light on a variety of different users that may interact with an E-care@home system, or other IoT technologies in the future.

    It should be acknowledged that the work presented in this technical report has been extracted from one of E-care@home scientific deliverables, MSR5.1b. The original deliverable, that was authored by Mälardalen University, SICS East and Örebro University, features also personas representing elderly multi-morbid users with specialized home healthcare and a number of use cases that pose challenging scenarios that highlight a range of possible interactions with the E-care@home system.

    User-centered evaluation of robotic telepresence for an elderly population2010Konferensbidrag (Refereegranskat)
    Abstract [en]

    The goal of our studies is to iteratively refine prototypes of the robot by involving end users in development cycles of the prototype throughout the project. The evaluations will be conducted with the aim of maximizing usability across geographic, demographic and cultural boundaries, as well as diverse home environments and user preferences and attitudes. The project ExCITE focuses on end users’ perspectives when using a robotic telepresence platform, the Giraff. The Giraff system consists of a tiltable screen and web camera mounted on a moveable robotic base that can be teleoperated. Our application area is elder care. We motivate the use of telepresence in elder care as a way to ensure safety, facilitate independent living and enhance social interaction.

    A study of spatial configurations in social robotic telepresence2012Ingår i: 2nd Workshop on Social Robotic Telepresence, 2012Konferensbidrag (Refereegranskat)
    Abstract [en]

    This paper presents tools for measuring the qualityof interaction in social mobile robotic telepresence. Themethodology is in part based on Adam Kendon’s theory of F-formations.The theory is based on observations of how bodiesnaturally orient themselves during interaction between peoplein real life settings. In addition, two presence questionnaires(Temple Presence Inventory and Networked Minds Social PresenceInventory), designed to measure the users’ perceptionsof others and the environment when experienced through acommunication medium were used. The perceived presence andease of use are correlated to the spatial formations between therobot and an actor. Use of the tools is validated experimentallyon a dataset consisting of interactions between an elder (actor)and 21 different users being trained in piloting a mobile robotictelepresence unit. The evaluation has shown that these tools aresuitable for evaluating mobile robotic telepresence and also thatcorrelations between the tools used exist. Further, also from alocal user perspective, the spatial formations have affected theperceived comfort in an interaction.

    Embedded Sensor Systems for Health Plus (ESS-H+) An overview of scientific areas and interdisciplinary target2019Ingår i: Abstractbok, 2019, s. 17-17Konferensbidrag (Refereegranskat)
    Abstract [sv]

    ESS-H+ will continue the work in the KKS research profile Embedded Sensor Systems for Health (ESS-H) at Mälardalen University. ESS-H has during six years provided important collaboration between researchers, industrial partners and healthcare organizations within three focus areas (Health monitoring at home, Health monitoring at work, and Infrastructure and communication).

    The focus of the new research profile ESS-H+ is that monitoring of humans should be able to be performed anytime, anywhere. Our research challenges are focused to the areas of Reliable acquisition and management of physiological data, and Reliable distributed data analysis. Reliable acquisition and management of physiological data is a fundamental prerequisite for advancing anytime, anywhere health monitoring, towards enabling remote monitoring of more serious health conditions than what is safely possible today. Reliable distributed data analysis is a fundamental prerequisite for enabling large-scale deployment of anytime, anywhere health monitoring. Both research challenges are complex and require multi-disciplinary research.

    The following important research goals will be addressed within ESS-H+: 

    • Reliable data acquisition, and design of suitable sensor systems for achieving this. 
    • Development of analysis and classification algorithms for physiological parameters. 
    • Achieve efficient distributed data fusion and decision support. 
    • Better utilization of the compute power of sensor nodes, and increased communication reliability: safety as well as security. 
    • Efficient integration of scientific results, from different scientific areas, to an efficient and user-friendly embedded sensor system. 

    The research in ESS-H+ will include research within the scientific areas (Biomedical sensor technology, Biomedical signal processing, Intelligent decision support, and Reliable and secure data communication) but also a strong integration between these areas, our collaborating companies, and the end users. Our main challenge within ESS-H+ will be this interdisciplinary integration that aims towards fully operating systems, thud providing efficient integration of scientific results, from different scientific areas, to an efficient and user-friendly embedded sensor system.

    Abstract [en]

    This article reports on the EU project ExCITE with specific focus on the technical development of the telepresence platform over a period of 42 months. The aim of the project was to assess the robustness and validity of the mobile robotic telepresence (MRP) system Giraff as a means to support elderly people and to foster their social interaction and participation. Embracing the idea of user-centered product refinement, the robot was tested over long periods of time in real homes. As such, the system development was driven by a strong involvement of elderly people and their caregivers but also by technical challenges associated with deploying the robot in real-world contexts. The results of the 42-months’ long evaluation is a system suitable for use in homes rather than a generic system suitable, for example, in office environments.

    A Novel Method for Estimating Distances from a Robot to Humans Using Egocentric RGB Camera2019Ingår i: Sensors, ISSN 1424-8220, E-ISSN 1424-8220, Vol. 19, nr 14, artikel-id E3142Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Estimating distances between people and robots plays a crucial role in understanding social Human-Robot Interaction (HRI) from an egocentric view. It is a key step if robots should engage in social interactions, and to collaborate with people as part of human-robot teams. For distance estimation between a person and a robot, different sensors can be employed, and the number of challenges to be addressed by the distance estimation methods rise with the simplicity of the technology of a sensor. In the case of estimating distances using individual images from a single camera in a egocentric position, it is often required that individuals in the scene are facing the camera, do not occlude each other, and are fairly visible so specific facial or body features can be identified. In this paper, we propose a novel method for estimating distances between a robot and people using single images from a single egocentric camera. The method is based on previously proven 2D pose estimation, which allows partial occlusions, cluttered background, and relatively low resolution. The method estimates distance with respect to the camera based on the Euclidean distance between ear and torso of people in the image plane. Ear and torso characteristic points has been selected based on their relatively high visibility regardless of a person orientation and a certain degree of uniformity with regard to the age and gender. Experimental validation demonstrates effectiveness of the proposed method.

    E-care@home: Initial Usability Considerations2016Ingår i: Abstractproceedings from Medicinteknikdagarna 2016, Örebro, Sweden, 2016Konferensbidrag (Refereegranskat)
    Abstract [en]

    The E-care@home project aims to develop a smart sensor and communication infrastructure with semantic interoperability capable of monitoring patients in their home. The system will use a wide array of sensors, both medical and environmental, and an advanced computer reasoning layer capable of interpreting sensor data and deliver natural language summaries of the patient health status. One critical issue is that of the usability of such a system to the users, i.e. patients and care providers.

    Abstract [en]

    In the era of data-driven science, corpus-based language technology is an essential part of cyber physical systems. In this chapter, the authors describe the design and the development of an extensible domain-specific web corpus to be used in a distributed social application for the care of the elderly at home. The domain of interest is the medical field of chronic diseases. The corpus is conceived as a flexible and extensible textual resource, where additional documents and additional languages will be appended over time. The main purpose of the corpus is to be used for building and training language technology applications for the “layfication” of the specialized medical jargon. “Layfication” refers to the automatic identification of more intuitive linguistic expressions that can help laypeople (e.g., patients, family caregivers, and home care aides) understand medical terms, which often appear opaque. Exploratory experiments are presented and discussed.
