In this paper we present our approach of an intuitive table-top 3D modeling tool in Augmented Reality. It allows the author to view 3D virtual objects within his natural working environment, to manipulate them and to create new 3D elements easily. The offered interaction techniques support the author's activity by a combination of tangible user interfaces with voice recognition, a gaze-based view pointer and 3D widgets as components of a multi modal user interface. Within the scope of this work, intuitive interaction techniques were realized to offer the participants an easy way of working within an augmented environment. User tests were performed to compare our approach to a WIMP-based desktop application and to an alternative AR modeling application.Categories and Subject Descriptors (according to ACM CCS): H.5.1 [Multimedia Information Systems]: Artificial, augmented, and virtual realities H.5.2 [User Interfaces]: Evaluation/methodology, Graphical user interfaces (GUI), Input devices and strategies
