The widespread use of digital cameras in mobile phones has led to an increase in the number of pictures captured and shared. However, the development of interfaces for visualizing image collections has not matched that growth. Most search methods are based on text descriptions and retrieve a large number of results on thumbnail 2D grids, which can be hard to analyze. Therefore, it is crucial to couple image retrieval with purposely designed interfaces. This paper covers the study of four different interfaces for the visualization of collections of images, including a regular 2D grid, a variable-size 2D grid, a pile of images, and a spiral. These interfaces were evaluated in a user test involving nine participants performing search tasks. We found that both grids exhibit higher usability and lower task times than the Pile and Spiral. The Variable Size Grid had lower usability scores than the Regular Grid, but it showed higher-quality task results and was preferred by the participants in this study.
