    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (344 KB) |  | HTML iconHTML  

    In this paper, we introduce an ECG measurement, analysis and transmission system which uses a mobile phone as a base station. The system is based on a small-sized mobile ECG recording device which sends measurement data wirelessly to the mobile phone. In the mobile phone the received data is analyzed and if abnormalities are found part of the measurement data is sent to a server for the use of medical personnel. The prototype of the system was made with a portable ECG monitor and Nokia 6681 mobile phone. The results show that modern smart phones are indeed capable for this kind of tasks. Thus, with their good networking and data processing capabilities, they are a potential part of the future wireless health care systems. View full abstract»

    Cardiovascular disease (CVD) is a major cause of death among humans. Rehabilitation after survival from a CVD is a long term process that includes frequent hospital visits, which could be avoided by the use of Hridaya on personal digital assistant (PDA) and mobile phones. These devices along with Hridaya could be used by the patients to report about their health to the physicians on a schedule basis who in turn can review their health conditions. List of clinical checkups would be similar in most cases of CVD and hence the objective of the study is to suggest Hridaya, a software as a service (SaaS) application, which would incorporate a decision support system along with some of these clinical routines.

  • Activity recognition using a hierarchical framework

    Page(s): 24 - 27
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (1125 KB) |  | HTML iconHTML  

    This paper describes an approach for modelling and detecting activities of daily life based on a hierarchy of plans that contain a range of precedence relationships, representations of concurrency and other temporal relationships. Identification of activities of daily life is achieved by episode recovery models supported by using relationships expressed in the plans. The motivation is to allow people with Alzheimerpsilas disease to have additional years of independent living before the Alzheimerpsilas disease reaches the moderate and severe stages.

  • Semi-automatic calibration of 3D camera images — Monitoring activities made easy

    Page(s): 28 - 31
    Save to Project icon | Click to expandQuick Abstract | PDF file iconPDF (381 KB) |  | HTML iconHTML  

    A major practical problem when implementing home monitoring using 3D camera technology is the calibration process which serves to relate the camera coordinate system to a coordinate system interpretable by the caregiver. In this paper, we propose a calibration algorithm which can relate both coordinate systems without performing actual measurements of the position of reference points in the room. The calibration tool is constructed such that it can be operated by any caregiver and hence eases the deployment of the home monitoring appliances. Our method (semi)automatically detects a plane corresponding to the ground floor in the three dimensional images. Random points from that plane are used to calculate rotation angles in a least squares manner. Experiments are performed to investigate how the obtained results depend on the parameters of the algorithm. View full abstract»

    Lifestyle related health problems are increasing rapidly. Many of them could be prevented or alleviated by sufficient physical activity, enough sleep, and a balanced diet. Individual citizens have the main responsibility for their own health and wellness management in their daily lives. Motivational tools based on modern technologies can support people in this task. Vivago Personal Wellness Manager (PWM) is a concept for personal wellness management, based on continuous activity monitoring with a wrist-worn device combined with immediate feedback on daily activity, e.g., sleep and physical activity. The concept allows long-term monitoring of activity patterns and includes PC software for detailed analysis of long-term data. We studied the ability of PWM to detect different levels of activity and to estimate energy expenditure. The classification accuracy of our method was 85.4% (SD: 6.3, range: 71.8-94.4%). The mean absolute error of the energy expenditure estimate was 8.7% (SD: 8.0, range: 1.2-32.1%). View full abstract»

    In this study we examine the Web-based ldquoself-learning system for preventing lifestyle-related diseaserdquo currently being developed by the National Institute of Health and Nutrition in order to determine areas for improvement, making the system easier to use. College students of the national registered dietitian training course adopted the roles of learners and supporters in the system and we analyzed their system use history and obtained feedback concerning system use via a questionnaire. There were many requests for the ability to use the system through a mobile phone. Moreover, it became clear that the data input methods involving, for example, calorie acquisition, need to be simplified. View full abstract»

    Security of telemedicine applications is not often given adequate importance by the developers and healthcare administrators primarily to reduce cost. Though some security safeguards are employed by these applications to comply with existing medical data security and privacy regulations, these are not adequate in todaypsilas context. Moreover, in a Web-based application environment not only the data but also the application itself is vulnerable to attackers. Keeping these concerns in mind, we present the design of a Web-based, four-tier telemedicine system named iMedik which is accessible over desktops as well as handheld devices. We have illustrated how the proposed system differs from existing three-tier Web applications. The compliance status of the application with HIPAA Security Guidelines has also been noted. The security measures described in our approach look into the four-tier architecture from an attackerpsilas viewpoint and present a simple road map for developing secure e-health application with anywhere, anytime availability.

    The success of integration and adaptation of pervasive computing and telemedicine technology in healthcare depends on the patients' compliance and trust to the introduced system. The aims of the present paper are to investigate, verify and evaluate the elderly heart patients' (EHP) compliance, trust and comfort in relation to a real-time wireless telemedicine system at home. A telemedicine system composed of a patient-unit, a GSM/GPRS network, a router, a data interpreter and a monitoring system was used. Twenty four non risky EHPs, aged (60plusmn5) years were recruited. A week of continuous ECGs for each of the EHPs were recorded. The experiments were carried out while the EHPs were performing their every day's activities. The EHPs' compliance, trust and comfort was verified and evaluated by three questionnaires. In average, 52% of the EHPs scored the user-friendly and usability of the system as reasonable. Only 16% sought help from the healthcare personnel in respect with the application of the patient-unit. 76% scored the reliability of the system as "reasonable" and 20% as "only now and then". It is concluded that the present system is reliable, functions with a clinically acceptable performance. The EHPs have expressed reasonable compliance and trust to the application of the system at home; however a number of the elderly were not satisfied with the weight and the user-interface of the ECG device.
