title: Validation of soft tissue properties in surgical simulation with haptic feedback.
abstract: Numerous experiments are being conducted to extract soft tissue values for their integration into VR surgical simulations with haptic feedback. Haptic feedback has been shown to be relevant in laparoscopic surgery, however to date no experiments have been conducted to test user sensitivity to changes in soft tissue values in surgical simulations, and how users perception of 'reality' differs from experimentally determined soft tissue values. In this study we conduct a series of experiments investigating haptic sensitivity, haptic differentiation and comparing experimental and empirical values.
