Abstract

We present a new widget, the IBar, for controlling all as-pects of a perspective camera. This widget provides an in-tuitive interface for controlling the perspective distortion in the scene by providing single handles that manipulate one or more projection parameters simultaneously (e.g., distance-to-object and lens aperture) in order to create a single per-ceived projection change (increasing the perspective distor-tion without changing the scene size). We demonstrate that novice users more easily learn how to manipulate the camera using the IBar.
