The paper “Harpoon Selection: Efficient Selections for Ungrouped Content on Large Pen-based Surfaces” will be presented at UIST 2011. In this paper, we present the Harpoon selection tool, a novel selection technique specifically designed for interactive whiteboards. The tool combines area cursors and crossing to perform complex selections amongst a large number of unsorted, ungrouped items. It is optimized for large-scale pen-based surfaces and works well in both dense and sparse surroundings. The results of a user study are described and analyzed to confirm our design. The study shows that the Harpoon tool performs significantly faster than Tapping and Lassoing.
