Real-Time Tracking of Visually Attended Objects in Virtual Environments and Its Application to LOD
2009
IEEE Transactions on Visualization and Computer Graphics
This paper presents a real-time framework for computationally tracking objects visually attended by the user while navigating in interactive virtual environments (VEs). In addition to the conventional bottom-up (stimulus-driven) saliency map, the proposed framework uses top-down (goal-directed) contexts inferred from the user's spatial and temporal behaviors and identifies the most plausibly attended objects among candidates in the object saliency map. The computational framework was
