I stumbled across this research project at University of San Diego: Passing the Bubble:

We study augmented video as a mechanism for improving collaboration and decision making. Our special focus is decision making that depends on decision-makers and information analysts sharing their understanding. The interaction between these two groups involves commanders passing their intent to their information analysts, then refining their plans and decisions on the basis of information gathered by their analysts, often using AUV’s. We examine how different ways of augmenting video differ in how cognitively efficient they are in creating shared understanding. Most people who have seen augmented video assume it to be a powerful mechanism for communicating complicated objectives and facts about situations. But little or no work has been done on:

determining which of the many ways of augmenting video are most effective, and

developing a cognitive theory that explains why these different methods differ in their potency and cognitive efficiency. Video, if properly annotated, promises to enrich and reshape collaborative exchanges. Our goal is to understand how to maximize the impact such videos will have on collaboration.

Why do I blog this? Might be interested for my thinking about to use replay tool in my research project.
