Bubble Clusters: An Interface for Manipulating
Spatial Aggregation of Graphical Objects
Nayuko Watanabe, Motoi Washida, Takeo Igarashi
Spatial layout is frequently used for managing loosely organized
information, such as desktop icons and digital ink.
To help users organize this type of information efficiently,
we propose an interface for manipulating spatial aggregations
of objects. The aggregated objects are automatically
recognized as a group, and the group structure is visualized
as a two-dimensional bubble surface that surrounds the
objects. Users can drag, copy, or delete a group by operating
on the bubble. Furthermore, to help pick out individual
objects in a dense aggregation, the system spreads the objects
to avoid overlapping when requested. This paper describes
the design of this interface and its implementation.
We tested our technique in icon grouping and ink relocation
tasks and observed improvements in user performance.
