We present the hold-and-move interaction technique [2], which uses an implicit input differentiation based on Guiard's "left-hand precedence in action" principle [1]. Hold-and-move associates the first contact point with the background and thus motion input from a single finger always controls panning. In order to manipulate individual items, the background must be held with the first finger. A second finger may then select an individual item and move it in relation to the background. In addition, the first finger may perform panning of the background and clutching while the second finger holds on to the selected item.
