Multimedia exploration is an entertaining approach for mul-timedia retrieval enabling users to interactively browse and navigate through multimedia collections in a content-based way. The multimedia exploration approach extends the traditional query-by-example retrieval scenario to be a more intuitive approach for obtaining a global overview over an explored collection. However, novel exploration scenarios require many user studies demonstrating their bene ts. In this paper, we present results of an extensive user study focusing on the comparison of 3-layer Multilayer Exploration Structure (MLES) structure with standard at k -NN browsing. The results of the user study show that principles of the MLES lead to better e ectiveness of the exploration process, especially when searching for a rst object of the searched concept in an unknown collection.
