A Computational Framework for Context-aware Adaptation of User Interfaces
The document presents a computational framework for context-aware adaptation of user interfaces, highlighting the necessity for customization in diverse usage contexts such as user profiles and environments. It discusses various existing frameworks and meta-models while introducing a triplet structure (CAMM, CARF, CADS) to enhance design and development processes. The framework aims to standardize terminology and provide a scalable solution to user interface adaptation challenges.
