Design of the Bare-Hand Volume Cracker for Analysis of Raw Volumetric Data

The Volume Cracker is a 3D interaction technique designed to allow rapid and intuitive visual analysis of raw volume data. However, the original Volume Cracker design was limited due to cumbersome and expensive hardware and the inability to interact with real volume data. New input devices such as the Leap Motion Controller enable 6-DOF tracking of bare hands and fingers, inspiring us to design a new version of the Volume Cracker addressing its prior limitations. We present a prototype of the Bare-Hand Volume Cracker that works directly on real volume datasets. We discuss the challenges we faced and the design choices we made while designing the BareHand Volume Cracker based on the Leap Motion Controller.
