Abstract in different language:	Direct manipulation has become a very popular interaction technique in GUI´s in the last few years. It allows the user to manipulate graphical objects in natural way. However, in complicated cases the user must perform complex manipulations that burden the user with many details. Therefore it is necessary to develop new techniques that are more user-friendly. One of many possible approaches is the use of constraints. By means of constraints it is possible to reduce the extent of interaction from the user as the constraints introduced express relations among objects that can be manipulated. This paper describes a new technique that allows for interacting with graphical objects in an effective way. Moreover the implemented system contains features that visualize constraints. This supports the user during interaction as he/she can clearly see the mutual links between objects.
