AN INNOVATIVE USER INTERFACE FOR INTUITIVE 3D-SKETCHING IN AN AUGMENTED REALITY ENVIRONMENT
For better support of the conceptual phase of product development a new tool is suggested that combines the advantages of paper based sketching and 3D software tools – a “3D-sketcher”. Acting directly in a three-dimensional working space requires new user interaction concepts that are different to current 2D-WIMP (Windows-Icons-Menus-Pointer) interfaces and allow intuitive working. A two handed interface emulates the familiar usage of paper and pencil. The Graphical User Interface (GUI) is based on a palette-like context menu that is displayed on demand directly at the actual cursor position. This enables the user to reach the core functions within short-distances.
