Using perceptual grouping for object group selection

Modern graphical user interfaces support the direct manipulation of objects and efficient selection of objects is an integral part of this user interface paradigm. For the selection of object groups most systems implement only rectangle selection and shiftclicking. This paper presents an approach to group selection that is based on the way human perception naturally groups objects, also known as the "Gestalt" phenomenon. Based on known results from perception research, we present a new approach to group objects by the Gestalt principles of proximity, curve-linearity, and closure. We demonstrate the results with several examples.
