DANSK DS/IEC/PAS 62883 PDF

This Publicly Available Specification (PAS) specifies a framework for adaptive handling of explicit interaction among humans and AAL spaces. This is based on a differentiation between explicit and implicit interaction as a consequence of the paradigm shift from Human-Computer Interaction to Human-Environment Interaction, further explained in the definition of the latter term. As a framework, a main subject matter of the specification is the identification of relevant areas for further standardization, thereby also looking at the interrelationships among the identified areas. The PAS also provides a first extensible specification in some of those areas. The proposed UI framework has been derived from the logical separation of application and presentation layers as depicted by Figure 2, and encompasses the following elements (Figure 3): - Analysis of the relationships between UI handlers and I/O devices without specifying possible languages, models, or abstract APIs for interaction with these devices, as there are certain international standardization activities that go in this direction2; - the language and model for describing application-specific dialogs / user interfaces as part of UI requests made by applications to the UI framework; - the adaptation concept and parameters needed to achieve adaptive UI and the way they affect UI requests; and - Protocols used by the UI framework to broker between UI handlers and applications as pluggable components.
