Bubble Radar. The inset picture shows the user selecting a target in a reduced representation map that uses Bubble Cursor - an enhanced area cursor
Bubble cursor. (a) the cursor changes its size dynamically such that only the target closest to the cursor center is selected. (b) The bubble cursor morphs to encompass a target when the basic circular cursor cannot completely do so without intersecting a neighboring target.
(1) potential targets;
(2) object to position;
(3) reduced representation of environment within the Bubble Radar;
(4) target closest to the bubble cursor is selected if pen will be released now the object will be transferred to that target;
(5) in simple radar mode the object can be dropped at any place.
