PileBars : Scalable Dynamic Thumbnail Bars APPENDIX : User study evaluation

In this appendix, we present some quantitative and qualitative comparisons among the PileBar interface and the ones of a couple of conventional image-browsers. In our tests, we aim to measure how fast users navigate thousands of images with image-browsers covering only a small part of the screen. In particular, the PileBar browser is compared with a horizontal thumbnail-bar and a browser with a grid layout.
