This paper introduces a gestural perceptual-based approach to select objects, i.e., nodes and/or edges along paths. Based on known results from perception research, we propose a model to detect perceptually salient paths formed by the Gestalt principles of good continuity and closure. Then we introduce gestural interaction techniques that enable users to select single or multiple perceptual paths, as well as resolving ambiguities in selection. The result of a user study shows that our system outperforms current techniques for path selection.
