Many touchscreen apps that support stylus or finger input provide a lasso tool, which is a free-hand selection tool. The lasso tool enables users to select strokes by drawing a closed path around a set of strokes to select them. However, selection using the lasso tool can be imperfect (not matching the user intent) and requires subsequent manual refinement. This disclosure describes a lasso tool for stylus apps that determines selection tolerance based on the speed with which the stylus is moved at different points of the selection path. A relatively slow stylus speed is taken as an indication that the user intends a precise (less inclusive) stroke selection, whereas a relatively fast stylus speed is taken as an indication that the user intends for a more inclusive (coarse) stroke selection. The described speed-sensitive lasso tool enables flexible, accurate, and efficient selection of strokes.
