Model-Based Design Of Multimodal Interaction For Augmented Reality Web Applications

Despite the increasing use of Augmented Reality (AR) in many different application areas, implementation support is limited and still driven by development at source-code level. Although efforts have been made to overcome these limitations, there is a clear gap between authoring environments and source code level framework approaches for creating AR interfaces for the web with multimodal control. Model-based design for interaction can offer support to fill this gap between authoring environments and frameworks. However, to the best of our knowledge, a declarative and model-driven design (MDD) has not yet been applied to model AR interfaces for a wide spectrum of modes. Thus, this paper presents an extension of the model-driven design to cope with interactors, whose novelty lies on the introduction of a modeling approach targeted at AR developers and designers in their task to design new forms of interactions that can be later used in authoring environments. To validate our approach, we demonstrate how a reality spanning Drag-and-Drop interaction can be modeled for an online furniture shop. And we implemented a gesture based control to show how new control modes can be added to an existing MDD-based design to extend the interaction capabilities.
