Attentive camera navigation in virtual environments

Gaining an accurate mental representation of real environments and realistic virtual environments is a gradual process. Significant aspects of an environment may be obvious to a trained expert, but not to the novice trainee. If a user does not know where to look, he or she may concentrate on irrelevant objects. This detracts from learning the locations of truly prominent landmarks. The paper explores attentive camera navigation, a technique that guides the user to focus on certain objects through automatic gaze redirection. Results of a user study suggest that this technique can help filter out unnecessary objects, and allow users to quickly understand the configuration of a selected subset of landmarks
