Inexpensive Non-Sensor Based Augmented Reality Modeling of Curves and Surfaces in Physical Space

Previous works in modeling of curves and surfaces in augmented reality (AR) space has used expensive sensors such as magnetic sensors. In this work, we propose an augmented reality system where a user can model interesting surfaces with her hands, and without expensive sensing systems. The system uses computer vision based methods for the tracking of the user’s head and hand position. Using a glove and the tracking system, the user can draw smooth lines or surfaces with her hands in a physical space. Also the user can intuitively modify the lines or surface created by pushing or pulling at the control points of the lines or curve in a tangible manner.
