Knowledge engineering and ontologies for object manipulation in collaborative virtual reality

This project describes an ontology for a collaborative engineering task. The task is to take apart an interactive 3D model in 3D space using virtual reality and to manipulate an object. The project examines a virtual environment in which two engineers can perform a number of tasks for manipulating object parts controlling a wiimote inside an immersive projection system. The interface recognizes hand-gestures of the engineers, pass commands to a VR modelling package via a gesture recognition system, perform the actions on the 3D model of the object, generating it on the immersive projection screen. We use retrospective protocol analysis for knowledge engineering and ontology building analysing the cognitive processes.6 page(s
