Presentation of Workshop on Technology for Healthcare and Healthy Lifestyle 2011 Thursday 1st Dec 2011 Session II http://www.tsb.upv.es/wths2011

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.

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.

9. OHMS profiling
OHMS 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.

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.

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.

16. Vital signs classification
1. NORMAL: safe situation.
2. TO BE CONTROLLED: possible
risky situation.
3. URGENT: risky situation.
4. EMERGENCY: emergency
situation.

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 changes

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.

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.

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 actuation
protocol.

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 elderly

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 been
solved through synchronized time fields within the user’s profile.
•Adequate reading and writing, and real time assessment of properties
changes.
