The Lifelog Search Challenge (LSC) is a venue where retrieval system researchers compete in solving tasks to retrieve the correct image from a lifelog collection. At LSC 2021, we introduce the PhotoCube system as a new competitor. PhotoCube is an interactive media retrieval system that considers media items to exist in a hypercube in multidimensional metadata space. To solve tasks, users explore the contents of the hypercube by dynamically (a) applying a variety of filters and (b) projecting the hypercube to a three-dimensional cube that is visualised on screen.
