Physically-Based Bimanual Volumetric Selection for Immersive Visualizations

This paper presents the details of a novel selection technique, Physically-Based Volumetric Selection, to combat challenges in selecting volumes of data using immersive display spaces. We present results on a physical experiment that we used to inform design and discuss the details of our proposed technique. We also present the results of a virtual experiment to evaluate feasibility, utility, and usability. A description of user strategies and design is included. Our results will have implications for applications that use alternative rendering techniques as well as volume selection to assist with selection tasks in a physically-based manner. Our technique can be used in combination with other selection and manipulation techniques to improve the overall desired performance of volumetric selection.
