Visual object database browsers are essentially based on two kinds of interactions: navigation within a collection of objects, and navigation between objects by the way of their relationships. These two interactional operators have proven to adequately support the main user task addressed by these tools, that is, exploring the states of a set of related objects. In temporal object databases, visual browsing tools should additionally support users tasks such as examining a snapshot of a collection of objects at a given instant, or detecting changes within object states. In this paper, we show that the two interactional operators supported by classical object browsers do not adequately address these tasks. We consequently propose an interactional operator dedicated to navigation through time, and we study how it may be orthogonally integrated with the above two.
