Mathematical Model for Physical Representation and Conflict Identification And An Approach for Analyzing Applicability and Usability of Gesture Recognition for Controlling Virtual Environments (Hardcover)

Physical modelling in Virtual Reality is a new and expanding field.In addition to this we take a practical approach to gesture recognition. Emphasis is placed on applicability and usability. In order to discuss practical aspects of gesture recognition, a theoretical 3-D modelling application is examined. Two different gesture recognition systems are introduced, extended and compared in an extensive field-test. These systems both have the characteristics of being computationally simple (fast, little demands on resources) while remaining reliable and extendable. Recognition- and success-rates in the high 90%'s can be achieved. Learning and adaptation to new gestures is automated successfully for both systems. Useful results concerning the choice of gestures, features and other system-relevant variables are obtained. Problems with general view-dependent interaction and modelling-specific vertex-selection are discussed and solutions implemented.
