The assessment of a situation/simulation is always based on the interplay between visual, audio and tactual/motoric sensory impressions that are compared to the corresponding expectations. By refering to previous experiences, the body is staking its claim in defining the constitution of reality. A graphical interface is experienced by the user as either a sign, his body or the depiction of signs as a result of his bodily functions. The accentuation of reality here lies on the possibility of bodily experience connected to body movement. Even minimal body movement when using a mouse can fulfill the given body expectations although "bodily experience without a body" is taking place.
 

The impression of volume and resistance is created despite the fact that the objects are only simulated graphically.
The graphical structure can be moved by clicking and dragging. The distance between the circles can be altered by simultaneously holding down the control key. The big circle can also be moved by clicking and dragging. It can be scaled by pulling its rim.
