Abstract

User Interface (UI) development is a challenging task as modern UIs are expected to be available across a wide range of diverse platforms while assuring high usability for heterogeneous users. Model-driven engineering principles have been applied in the context of multi-device and cross-device UI development to tackle complexity in development. While previous work related to usability evaluation of model-driven UIs primarily focused on single- and multi-device UIs, an investigation of the usability of model-driven cross-device UIs was not fully covered yet. In this paper, therefore, we present a model-driven UI development (MDUID) approach for cross-device UIs and analyze whether the applied MDUID approach has a positive impact on the usability of the generated UI. To accomplish this, we conduct a usability evaluation based on the generated UI for a cross-channel banking web application. The usability evaluation results provide detailed feedback regarding fulfillment of different usability criteria and enable improvement of involved models as well as model transformations.
