    abstract="Eye tracking is one of the most prominent modalities to track user attention while interacting with computational devices. Today, most of the current eye tracking frameworks focus on tracking the user gaze during website browsing or while performing other tasks and interactions with a digital device. Most frameworks have in common that they do not exploit gaze as an input modality. In this paper we describe the realization of a framework named viGaze. Its main goal is to provide an easy to use framework to exploit the use of eye gaze as an input modality in various contexts. Therefore it provides features to explore explicit and implicit interactions in complex virtual environments by using the eye gaze of a user for various interactions. The viGaze framework is flexible and can be easily extended to incorporate other input modalities typically used in Post-WIMP interfaces such as gesture or foot input. In this paper we describe the key components of our viGaze framework and additionally describe a user study that was conducted to test the framework. The user study took place in a virtual retail environment, which provides a challenging pervasive environment and contains complex interactions that can be supported by gaze. The participants performed two gaze-based interactions with products on virtual shelves and started an interaction cycle between the products and an advertisement monitor placed on the shelf. We demonstrate how gaze can be used in Post-WIMP interfaces to steer the attention of users to certain components of the system. We conclude by discussing the advantages provided through the viGaze framework and highlighting the potentials of gaze-based interaction.",
