This document explores the intricacies of modality-independent and dependent implementations in user interface modeling, focusing on the distinctions between platform and environment contexts. It examines how context-of-use impacts the development of domain tasks in both abstract and concrete UI domains for mobile and desktop platforms. The discussion highlights the integration of transformation dependencies and mappings in managing user interactions effectively across diverse modalities while ensuring implementation independence.
