A device for the control of electronic apparatus for the handling of graphic objects on a multi-contact tactile screen

摘要

The device has a series of main graphical objects (2), and a series of subordinate graphical objects (3a-3d), each having a subordinate function and being associated to a subordinate processing path. The subordinate graphical objects are placed on a visual display screen (4) at locations different from that of the main graphical objects. The main graphical objects are arranged such that both the series are handled by groups of pointing units (5, 6) e.g. stylus. Manipulation of one of the subordinate graphical objects modifies properties of one of the main graphical objects.
