This paper presents a new pen-based technique, Tilting-Twisting-Rolling, to support compass geometric construction. By leveraging the 3D orientation information and 3D rotation information of a pen, this technique allows smooth pen action to complete multi-step geometric construction without switching task states. Results from a user study show this Tilting-Twisting-Rolling technique can improve user performance and user experience in compass geometric construction.
