Bridging the Gap between Real and Virtual Modeling - A New Approach to Human - Computer Interaction -

Three-dimensional computer-aided modeling of dynamic processes supported by virtual reality techniques such as 3D-stereo viewing and nD manipulation devices does not reach the usability (ease, concreteness, intuitiveness, directness) that we experience in modeling with real physical objects. Pure virtual prototyping may reduce cognition and communication. To solve this problem we introduce the concept of a Graspable Real Reality User Interface which bridges two modeling worlds: the real world of physical objects and the virtual world of signs and images. Sensorized user hands will couple physical objects of the real world to virtual objects, thus allowing fairly unrestricted manipulation and expression. In this way modeling with real physical objects can create an abstract virtual model. Some applications of this concept will be presented here.
