Inexpensive non-sensor based augmented reality modeling of curves and surfaces in physical space

Abstract

Previous work in modeling 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, without expensive sensing systems. The system uses computer vision based methods for tracking 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. The user can also intuitively modify the lines or surface created by pushing or pulling at the control points of lines or curves in a tangible manner.
