  • 1. Distributed and synchronized user’s profile management for Ambient Assisted Living Presented by Viveca Jimenez-Mixco 01.12.11- Valencia
  • 2. Motivation and Introduction The ageing process involves biological and physiological changes that may influence older persons’ abilities to perform tasks of daily living and to interact with their social and physical environments.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 3. Population pyramids, EU27, 2008-2060 Due to improvements occurring within health care systems, longevity has increased and the age distribution of the population in industrialized countries has shifted towards older age groups. This noticeable aging will continue over the next decades.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 4. Projected age dependency ratios for selected yearsDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 5. Oasis Health Monitoring System Improving elderly people’s quality of life by facilitating them to control their daily health statusDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 6. Oasis Health Monitoring SystemDefinition and personalization of the user’shealth profileMonitorization through sensorsAssessment, Education and InformationAlerting and assisting in case of emergencyDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 7. Traditional systems vs. OHMS Tradicional teleassistance OHMS care Through the use of •OSGi architecture •Web Services •XML •BluetoothDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 8. OHMS profiling • Aim • Profile description • Biomedical Sensors • Vital Signs classification • Profiles network communicationDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 9. OHMS profilingOHMS profile is generated for each user, allowing the system to: • Be more effective. • Personalise the services offered to the elderly. • Increase the safety of the user, by detecting in advance possible risky situations and alerting relatives and caregivers.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 10. Profile description (I) Properties group Write Launch Helps taking Permission Alerts decisions General Information Physician and NO NO elderly General Health Physician NO YES Information Treatment, Physician and YES YES recommendations, system measurements USER PROFILE PROPERTIES CLASSIFICATION General demographic information: contains information about the user like name, age, affiliation, phone, relative’s name, relative’s phone, reference doctor, reference hospital and other demographic information. General health information: contains information about the user’s health. The most important field is the health condition that describes the diseases suffered by the elderly.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 11. Profile description (II) Treatments, recommendations and measurements: contains information about the treatments, recommendations and measurements values. This group of properties is the most important. Properties group Description Decision Medication Describes the medication the user Reminds the user to takes. take the medication. Biomedical parameters Biomedical sensors values of the Triggers the control of last measurement taken by the user. changes that sends the alerts Recommended Measurements the user should Decides what kind of measurements monitor. Also stores for each alert should be sent. biomedical parameter the ranges of values that classify the measurement.

  • 16. Vital signs classification 1. NORMAL: safe situation. 2. TO BE CONTROLLED: possible risky situation. 3. URGENT: risky situation. 4. EMERGENCY: emergency situation.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 17. Profile Management Collection of information: explicitly or implicitly, through: • Direct patient intervention. • Direct physician intervention. • Sensors that monitor the users’ vital signs. Method applied to handle the profile information: • Adequate reading and writing. • Prevents simultaneous writing in one profile property, avoiding inconsistencies within the information. • Real time assessment. • Enables to control properties changesDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 18. Profiles network communication The Web Services are the selected tool for network communications, ensuring: • Communication security • Synchronization between the local profile in the user’s device and the remote one in the Profile Web service.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 19. Results • Components of the system • Profile XML • Profile Web Service • Profile Manager bundle • Profile web service stubDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia

  • 21. Profile XML Field Description Key Property name to validate Default Default value of the property Type Type of value stored Description Description of the property SCHEMA SINGLE PROPERTY STRUCTURE Field Description Entry Property name Time Timestamp of the last change Type Type of value stored Value Property value XML SINGLE PROPERTY STRUCTUREDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 22. Profile Web Service • System’s core: located in the server where the user’s XML profiles are stored. • Accessed through: • Profile Manager • Profile Web Service stub •Controls the adequate reading and writing. Thus, the Profile Web Service ensures properties to always be up-to-date and valid.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 23. Profile Manager Bundle• Profile Manager is an OSGi bundle• Located in the elderly personal computer.• Allows to: •Read and write properties. •Listen changes in the profile.• Profile Manager listener follows an actuationprotocol.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia

  • 25. Profile web service stub •Located in the physician personal computer. • Allows reading and writing properties of the user profile. •Using this web service, the physician can: • Notify changes in the medication. • Change the recommended measurements • Receive alerts from the vital signs measurements of the elderlyDistributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
  • 26. Conclusions • OHMS is a solid tool for controlling the health status of the elderly. • Stored information is always valid and up-to-date in the elderly or physician clients.•Network problems that may arise causing reception errors have beensolved through synchronized time fields within the user’s profile.•Adequate reading and writing, and real time assessment of propertieschanges.Distributed and synchronized user’s profile management forAmbient Assisted Living 01.12.11- Valencia
