This project concerns the application of haptic feedback to a VR laparoscopic surgery simulator. Haptic attributes such as mass, friction, elasticity, roughness and viscosity are individually modeled, validated and applied to the existing visual simulation created by researchers at Monash University. Haptic feedback is an essential element in an immersive and realistic virtual reality laparoscopic training simulator. The haptic system must display stable, continuous and realistic multi-dimensional force feedback, and its inclusion should enhance the simulators training capability. Stability is a recurring concern throughout haptic history, and will be tackled with the implementation of a stable control algorithm and a passive environment model. Haptic force feedback modeling, systems implementation and validation studies form the principal areas of new work associated with this project.
该项目涉及将触觉反馈应用于虚拟现实腹腔镜手术模拟器。诸如质量、摩擦力、弹性、粗糙度和粘性等触觉属性被分别建模、验证并应用于莫纳什大学研究人员创建的现有视觉模拟中。触觉反馈是沉浸式和逼真的虚拟现实腹腔镜训练模拟器中的一个关键要素。触觉系统必须显示稳定、连续且逼真的多维力反馈，并且其加入应增强模拟器的训练能力。稳定性是触觉发展历程中反复出现的一个问题，将通过实施稳定控制算法和被动环境模型来解决。触觉力反馈建模、系统实现和验证研究构成了与该项目相关的新工作的主要领域。
