List navigation devices such as scrollbars provide a simple way to browse and find items in a list, but they typically do not communicate information about individual list entries. This paper presents two alternative devices, a mural bar and a pile bar, which encode information about each entry into the trough of the bar. Results from an experiment suggest that these new devices lead to improved user performance on typical list-based tasks.
