Curve Analysis of Course of Motion in Virtual Environments

چکیده
This paper proposes a novel method of modelling trajectories followed by users, while they navigate within a virtual environment. Bézier curves provide a good approximation of trajectories, and the results indicate that the method provides a basis for the diagnosis of navigational patterns. The method offers three indicators: goodness of fit, average curvature and number of inflexion points which study results indicate that carry important information about user performance, specifically spatial knowledge acquisition.
