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.

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.

• 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.

OHMS profile is generated for each user, allowing the system to:

Profile description (I)

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

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.

Properties group Write Permission

Launch Alerts

Helps taking decisions

General Information Physician and elderly

NO NO

General Health Information

Physician NO YES

Treatment, recommendations,

Physician and system

YES YES

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.

USER PROFILE PROPERTIES CLASSIFICATION

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

takes. Reminds the user to take the medication.

Biomedical parameters Biomedical sensors values of the last measurement taken by the user.

Triggers the control of changes that sends the

Measurements the user should monitor. Also stores for each

biomedical parameter the ranges of values that classify the

measurement.

Decides what kind of alert should be sent.

Vital signs classification

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

1. NORMAL: safe situation.

2. TO BE CONTROLLED: possible risky situation.

3. URGENT: risky situation.

4. EMERGENCY: emergency situation.

Profile Management

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

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

Profiles network communication

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

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.

Results

XML SINGLE PROPERTY STRUCTURE

Profile Web Service

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

• 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.

Profile Manager Bundle

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

• 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.

•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

Conclusions

01.12.11- Valencia Distributed and synchronized user’s profile management for Ambient Assisted Living

• 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.

Thank you!
