Abstract
Manufacturing activities in the industries are now deelply associated with advanced information technologies. A complex manufacturing space (CMS) is a formalization of a manufacturing system synthesized by a real system and a virtal system. In this paper, the interface betweeen human users and a CMS is mainly discussed, after the brief introduction of a CMS. Universal pointing is a key technology which enables a user to easily indicate various types of objects in a CMS with many input devices.
