Interoperable Assistive Technologies


The increasing number of elderly citizens in our society puts an increasing strain on traditional healthcare systems’ resources. Ambient Assisted Living (AAL) solutions seek to reduce the impact of this tendency as well as provide a way for the elderly to continue to live in their home environment as long as possible with a good quality of life and independence.

However, due to the diverse nature of existing products and services, ensuring interoperability between them is important in order to provide flexible and adequate solutions for an individual’s particular needs.

The goal of this dissertation is to present a possible solution for this problem using Electronic Health Records (EHRs) and health information standards. For this purpose a repository was implemented to store records in Extensible Markup Language (XML) format following the openEHR standard, as well as an application in the Java programming language to create, manage and query these records in the repository and an interface engine (Mirth Connect) was used to provide message transformation capabilities implemented in JavaScript between different standards, particularly Health Level Seven version 2.x (HL7 v2.x) and openEHR.
