چکیده

Visual object database browsers are essentially based on two kinds of interactions: navigation within a collection of objects, and navigation between objects via their relationships. These two interactional operators have proven to adequately support the main user task addressed by these tools, i.e. exploring the states of a set of related objects. In temporal object databases, visual browsing tools should additionally support users tasks such as studying a snapshot of a collection of objects at a given instant, or detecting and examining 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 can be orthogonally integrated with the above two.

Visual Exploration of Temporal Object Databases

Two complementary families of users’ tasks may be identified during database visualization: data browsing and data analysis. On the one hand, data browsing involves extensively exploring a subset of the database using navigational interaction techniques. Classical object database browsers provide means for navigating within a collection of objects and amongst objects by way of their relationshi...

Temporal Extent for Global Change Research Databases

We propose temporal extent, a concept that can be used to produce summary or abstracted information about the values of temporal attributes in a database relation or class of objects. In its simplest form, the temporal extent is a one-dimensional interval representing the minimum and maximum time points of the instances in a class. More generally, a set of temporal intervals are used to capture...

Moving Visual Representations of Video Objects for Content

This paper proposes object-based moving visual representations for quick browsing of video content. These representations are hierarchical, such that at the coarse level a sequence of alpha planes provides a moving representation of object shape and motion information for object contours. Alternatively, a 2D mesh representation provides a complete visual representation of object motion and shap...
