Quantity versus quality

Abstract

In this paper we present our findings from an experiment designed to test the effectiveness of complex, thumbnail based layouts and the interaction methods required, in video retrieval scenarios for handheld devices such as smartphones. Our evaluation explores the relationship between the number of thumbnails (Quantity) visible on screen and their discernible detail (Quality) with regards to the related necessary amount of interaction. The results indicate that such layouts achieve a very high rate of accuracy and speed but that the nature of the interaction is of critical importance for the success of the system.
