3DColAR: Exploring 3D Color Selection and Surface Painting for Head Worn Augmented Reality using Hand Gestures

Color selection and surface painting has been largely unexplored in head-worn Augmented Reality (AR) using hand gestures. In this demonstration we present 3DColAR: A system that implements several 2D and 3D techniques for color selection. We also implement two key approaches for painting a virtual 3D model using midair hand gestures. This includes a virtual pen which the user can grasp using their hand, akin to a real pen and the use of the user's fingertip directly on the virtual 3D model. We hope to explore how these various techniques effect user's efficiency and accuracy when performing surface painting of virtual objects using mid-air hand gestures via. several user studies.
