From Desktop to Touchless Interfaces: A Model Based Approach

With the increasingly low cost of motion-sensing technology, touchless interactive interfaces may become a new ingredient in the evolution of content intensive web applications from single-platform (desktop) to multi-platforms use. While the migration from desktop to mobile devices has been widely studied, there is limited understanding on how to include touchless interfaces in this "going multi-channel" evolution. The paper focuses on the design issues that are induced by this process. We propose a model-based design approach that supports information reuse and exploits a systematic mapping from content structures to interaction tasks and touchless gestures. We then describe a case study in the cultural heritage domain to exemplify our method.
