Abstract

Shape recognition with indirect touch is an important task in medical field to identify and perceive state of tissue hidden behind other tissues. For simulating indirect touch, this paper adapts FEM-based interaction model between elastic objects to collisions of tissue models in virtual environment, and fingers stroking movement is supported for shape recognition by finger assuming use of point-based haptic interface. Experiments using convex and concave primitive models and virtual prostate tissue model were conducted to verify availability of our simulation models for shape recognition with indirect touch.
