PURPOSE
A haptic algorithm to simulate the interaction between a surgical drill and bone using a constraint-based algorithm has been previously demonstrated. However, there has been no blinded study to determine whether this algorithm is preferred by professionals who commonly use this type of system METHODS: Fourteen otologic surgeons were presented with a spring-damper model and a constraint-based model of drill-bone interaction rendered on a low-cost haptic device with only linear feedback. The participants were blinded as to what algorithm they were using. They then answered survey questions about their opinions of the models.
RESULTS
The surgeons overwhelmingly preferred the constraint-based model. They generally preferred the constraint-based model in the individual questions as well.
CONCLUSIONS
Follow-up work can be done to fine-tune the parameters in the model, but this study shows that a sophisticated algorithm can make a significant difference even on a low-fidelity haptic device.
目的
先前已经展示了一种使用基于约束的算法来模拟手术钻头与骨骼相互作用的触觉算法。然而，目前还没有盲法研究来确定这种算法是否受到经常使用此类系统的专业人员的青睐。方法：14 名耳科外科医生使用低成本触觉设备呈现了一个弹簧阻尼器模型和一个钻头-骨骼相互作用的基于约束的模型，该模型仅具有线性反馈。参与者对他们正在使用的算法一无所知。然后，他们回答了有关模型看法的调查问题。结果：外科医生非常喜欢基于约束的模型。他们通常在个别问题中也更喜欢基于约束的模型。结论：可以对模型的参数进行进一步调整，但这项研究表明，即使在低保真度的触觉设备上，复杂的算法也能产生显著的差异。
