A Web 2.0 Model for Patient-Centered Health Informatics Applications

Web 2.0 standards define a distributed embeddable application model that can be used to implement medical best practices in the form of a medical protocol.

STEPSTONE: An Intelligent Integration Architecture for Personal Tele-Health

STEPSTONE is a joint industry-university project to create open source technology that would enable the scalable, “friction-free” integration of device-based healthcare solutions into enterprise systems using a Service Oriented Architecture (SOA). Specifically, STEPSTONE defines a first proposal to a Service Oriented Device Architecture (SODA) framework, and provides for initial reference implementations. STEPSTONE also intends to encourage a broad community effort to further develop the framework and its implementations. In this paper, we present SODA, along with two implementation proposals of SODA’ device integration. We demonstrate the ease by which SODA was used to develop an end-to-end personal healthcare monitoring system. We also demonstrate the ease by which the STEPSTONE system was extended by other participants ?Washington State University ?to include additional devices and end user interfaces. We show clearly how SODA and therefore SODA devices make integration almost automatic, replicable, and scalable. This allows telehealth system developers to focus their energy and attention on the system functionality and other important issues, such as usability, privacy, persuasion and outcome assessment studies.

Toward a collaboration model for smart spaces

Developing and deploying a pervasive space is a multi-disciplined process where knowledge from various domains intersects. How can individual roles efficiently contribute their expertise and smoothly integrate their work to create a pervasive space? How does system design and architecture enable effective decoupling of these roles? Based on our own experience in building several pervasive systems including the Gator Tech Smart House (GTSH), this paper discusses a collaboration model that allows multiple roles, working together, to design, develop, and maintain pervasive systems in physical spaces such as homes and buildings. The paper first introduces each role in the model with its designated resources and responsibilities. It then explains the collaboration model and shows how it can be applied in real-world deployments. This paper does not claim to provide an ultimate solution to a well-defined problem. Rather, it attempts to define an increasingly important problem and provides an installment of thoughts toward solutions. We hope the paper raises awareness to the importance of this subject and leads to a productive discussion during and following the workshop.
