Abstract

One of the main goals of the HP Interactive Visual Interface (HP IVI) project was to leverage features from current user interface and software design technologies and blend the best of each into the feature set and design of the application program interface (API) functions. In doing so, the project team investigated windowing, graphics, the X toolkit (Xt Intrinsics), widgets, and object-oriented design. This article discusses the features used from each of these technologies, and how these features are incorporated into the internal design and implementation of the API functions.

Chapter
This chapter lays the foundation for understanding the ability of interoperability and standards-based systems to empower digital health by defining key terms and describing programs and initiatives. Interoperability is a critical infrastructure for health systems to enable data that are seamlessly and securely available across multiple sources. Barriers to interoperability are described, including short- and long-term strategies for overcoming such barriers. The evolving digital health ecosystem creates a need for initiatives that inform and enable the interoperability landscape. This chapter outlines efforts to accelerate the global adoption of innovative, standards-based health IT systems, which will advance the promise of digital health.KeywordsInteroperabilityStandardsDataHealthHealthcare
