transitional objects act between the staging space and imaginative space, i.e. the outer world to be acted on and the psychic reality of the perceptor, his individual envisioning. Transitional objects have an analogous pointer function as 'response cues', but they are also active objects that are handled in both the everyday world and the simulation and enable us to act at all. Transitional objects make it possible to transfer the center of intended user action from the hardware to the software. When an activity is no longer associated with the mouse as an object all action becomes related to the imaginative space. The interface is no longer themed and dissolves into the background.
