Abstract
Currently, many mobile devices provide various interaction styles and modes which create complexity in the usage of interfaces. The context offers the information base for the development of Adaptive user interface (AUI) frameworks to overcome the heterogeneity. For this purpose, the ontological modeling has been made for specific context and environment. This type of philosophy states to the relationship among elements (e.g., classes, relations, or capacities etc.) with understandable satisfied representation. The context mechanisms can be examined and understood by any machine or computational framework with these formal definitions expressed in Web ontology language (WOL)/Resource description frame work (RDF). The Protégé is used to create taxonomy in which system is framed based on four contexts such as user, device, task and environment. Some competency questions and use-cases are utilized for knowledge obtaining while the information is refined through the instances of concerned parts of context tree. The consistency of the model has been verified through the reasoning software while SPARQL querying ensured the data availability in the models for defined use-cases. The semantic context model is focused to bring in the usage of adaptive environment. This exploration has finished up with a versatile, scalable and semantically verified context learning system. This model can be mapped to individual User interface (UI) display through smart calculations for versatile UIs.
Highlights
Mobile phone user interfaces provide adaptivity features options regardless of context of use
As per requirements of User centered design (UCD) process model the User context ontology (UCO) specifies the user context, mapping functions provide the impact of user context on interface development and the resultant product is tested against the user requirements
2.2.3 User Context Ontology Mapping to Adaptive Interface Rendering the previous use cases described in UCO engineering process for different context, respective interfaces styles are followed
Summary
Mobile phone user interfaces provide adaptivity features options regardless of context of use. It is user’s choice to select any adaptivity feature according to their choice. Context has been modelled in various scenarios and application domain focused on different context elements like user demography, devices and software capabilities etc. There is still need to study the elements of context influencing the usability aspects of mobile device. The previous solutions provide programmable libraries, overlays and patches to add adaptivity in current user interfaces. These user interface adaptivity solution are not aligned with any standard user interface development process model [5,7]. The adaptive user interface models are needed to be formed in response to the context
