Touch based selection of graphical elements

摘要

The present invention extends to methods, systems, and computer program products for touch based selection of graphical elements. Embodiments of the invention improve the usability of interacting with data visualizations. When multiple graphical elements are covered by a finger touch, a gesture recognition component detects ambiguity in the selection. In response, a visualization component draws additional regions around the touched location. The additional regions correspond to the covered graphical elements covered. Thus, a user is made aware of the graphical elements covered by his or her finger. These additional regions are touch friendly and more easily selectable. A finger can be moved into one of the additional regions and released to finish the selection. The gesture recognition component interprets this gesture as if the user tapped directly and unambiguously on the corresponding graphical element.
