Abstract

This paper describes a novel, interactive multimodal framework that enables a network of friends to effectively visualize and browse a shared image collection. The framework is very useful for geographically disconnected friends to share experiences. Our solution involves three components - (a) an event model, (b) three new spatio-temporal event exploration schemes, and (c) a novel technique for summarizing the user interaction. We develop a simple multimedia event model, that additionally incorporates the idea of user viewpoints. We also develop new dissimilarity measures between events, that additionally incorporate user context. We develop three, task driven, event exploration environments - (a) spatio-temporal evolution, (b) event cones and (c) viewpoint centric interaction. An original contribution of this paper is to summarize the user-interaction using an interactive framework. We conjecture that an interactive summary serves to recall the original content better, than a static image-based summary. Our user studies indicate that the exploratory environment performs very well.
