3.1.3.1. Without joint shift
The movement of a sign can be reduced or extended without a change in the joints articulating the movement. The sign bicycle, for example, is shown in Figure 2.56a in its citation form, articulated at the elbow joint. In Figure 2.57b, bicycle is articulated with a larger circular movement, but still at the elbow joint.
Furthermore, one auhor describes that signs can be shouted by adding an articulator-internal movement to a sign which involves only a path movement, or vice-versa. Although articulator-internal movements are typically smaller than path movements, the combination makes the whole sign better perceivable.
