- In graphical user interfaces, users can select multiple objects simultaneously via lasso selection. This can be implemented, for example, by having users select objects by looping around their centers or entire areas. Based on differences in lassoing criteria, we presume that the performance of the criteria also differs. In this study, we compare three lassoing criteria and model lassoing motions while considering these criteria. We conducted two experiments; participants steered through straight-line and one-loop paths by using three criteria. The participants handled the lassoing criteria correctly and performed lassoing at appropriate speeds for each path shape. Although the drawn trajectories varied depending on the lassoing criteria, the criteria in the performance and subjective evaluations did not differ significantly. Additionally, from our results, we build a baseline model to predict the movement time by considering the lassoing criteria. We also discuss further experiments to predict movement time under more complex conditions.
