Controlling interactions between graphical objects

摘要

The invention relates to a method for controlling interactions between at least two objects. On pressing an activation button on a user device a user can set up an expanding boundary around one of the objects. The boundary expands up to a maximum distance. If a second object comes into contact with the boundary then the direction of movement of the second object may be altered. The speed of movement of the second object may also be altered. Alternatively, the shape of the second object may be altered on the second object coming into contact with the boundary.
