We present a new virtual reality-based interaction metaphor for semi-automatic segmentation of medical 3D volume data. The mouse-based, manual initialization of deformable surfaces in 3D represents a major bottleneck in interactive segmentation. In our multi-modal system we enhance this process with additional sensory feedback. A 3D haptic device is used to extract the centerline of a tubular structure. Based on the obtained path a cylinder with varying diameter is generated which in turn is used as the initial guess for a deformable surface.
