Abstract
Increasingly, multiple views on the same scene may be made available via a network of sensors in security and surveillance applications. Similarly, virtual reality and gaming applications may provide a user with more than one view on a scene in an attempt to improve user orientation. Previous work has demonstrated the utility of ‘visual momentum’ by showing an advantage in spatial judgments when users are provided with a transition between 2D and perspective views. However, no prior research has examined the utility of smooth transitions between different perspective-rendered views of the same scene. The present experiment compared two types of smooth transition between perspective-rendered views, and demonstrated that transitions generally provide an advantage on a spatial judgment task. Notably, transitions between perspective views did not need to include a bird’s eye view of the scene in order for users to make improved line-of-sight judgments.
