Abstract
A method of controlling a cursor displayed on a display device is provided. A three-dimensional environment is displayed on a display device. A cursor and a plurality of objects are displayed on the display device within the three-dimensional environment. The cursor comprises a zone defining a volume to identify at least one object that is at least partially located within the volume. The size of the volumetric activation zone is dynamically adjusted so that a predetermined constraint is satisfied. The predetermined constraint is a function of at least a relationship between the volumetric activation zone of the cursor and at least one of the plurality of objects.
