A blueprint for integrated eye-controlled environments

Eye-based environmental control requires innovative solutions for supporting effective user interaction, for allowing home automation and control, and for making homes more "attentive" to user needs. Several approaches have already been proposed, which can be seen as isolated attempts to address only partial issues and specific sub-sets of the general problem. This paper aims at tackling gaze-based home automation as a whole, exploiting state of the art technologies and trying to integrate interaction modalities than are currently supported and that may supported in a near future. User-home interaction is sought through two, complementary, interaction patterns: direct interaction and mediated interaction. Integration between home appliances/devices and user interfaces is granted by a central point of abstraction/harmonization called House Manager. Innovative points can be identified in the wide flexibility of the approach which allows on one side to integrate virtually all home devices having a communication interface, and, on the other side, mixes-up direct and mediated user interaction exploiting the advantages of both. A complete discussion about interaction and accessibility issues is provided, justifying the presented approach from the point of view of human-environment interaction.
