Abstract. We discuss interaction techniques in systems based ondirect manipulation of the objects in the canvases andproposes a model to manager such interactions. This model reduces the programming effort by providing an appropriate abstraction of the interaction tasks. A class library that implements these abstractions is also presented. Two application programs developed with this class library allow us to draw some conclusions.
