Abstract
The ability to manipulate the viewpoint is critical to many tasks performed in virtual environments (VEs). However, viewers in an information-rich VE are particularly susceptible to superfluous data and are easily distracted. Attentive Interaction techniques can address this issue by allowing the viewer to explore freely while allowing the system to suggest optimal locations and orientations. In this study, we examine the effectiveness of two interaction techniques. The first technique, called the Attentive Camera, is characterized by the system automatically aligning the viewpoint with the ideal direction of gaze as the viewer explores the environment. In the second technique known as the Attentive Flashlight, the ideal gaze direction is used to aim a spotlight, illuminating objects of interest. Study participants used these techniques to complete four search tasks in a virtual art gallery.
