Interest estimation based on dynamic bayesian networks for visual attentive presentation agents

In this paper, we describe an interface consisting of a virtual showroom where a team of two highly realistic 3D agents presents product items in an entertaining and attractive way. The presentation flow adapts to users’ attentiveness, or lack thereof, and may thus provide a more personalized and userattractive experience of the presentation. In order to infer users’ attention and visual interest regarding interface objects, our system analyzes eye movements in real-time. Interest detection algorithms used in previous research determine an object of interest based on the time that eye gaze dwells on that object. However, this kind of algorithm is not well suited for dynamic presentations where the goal is to assess the user’s focus of attention regarding a dynamically changing presentation. Here, the current context of the object of attention has to be considered, i. e., whether the visual object is part of (or contributes to) the current presentation content or not. Therefore,...
