为了研究被试者输出特定目标力的精度，以及输出精确力能力的转移效果，对6个被试者进行了3个力控制训练。训练过程中，被试者两手分别操作1台力反馈设备，用右手按压虚拟墙输出目标力，左手感受来自设备的振动反馈。实验结果表明，经过一次完整的触觉任务训练后，被试者对目标力的控制精度有显著提高。随着训练次数的增加，力控制绝对精度提高不明显，但绝对误差精度的偏差逐渐减小。训练结束后，在没有振动反馈的情况下，被试者输出1 N操作力的平均水平为（0．96±0．06）N。在随后进行的模拟牙科探诊实验结果表明，当操作工具和材料发生改变时，被试者的力控制能力仍然能够保持训练后的精度水平，为最终实现训练效果的转移提供了依据。

Three force control experiments are conducted to explore the accuracy of producing the target force and the transfer effect of force control.Six subjects were involved in the force control training task and operated the devices with both hands.The participants pressed the virtual wall with their right hands and accepted vibration feedback with their left hands.The results show that the control accuracy on force magnitude was significantly enhanced after only one session of haptic training.With the increas-ing training sessions,the absolute accuracy is not obviously improved,but the deviation is decreased.After the training,the pro-ducing target force is (0.96±0.06)N without vibration feedback.In the simulation task of dental probing,it is shown that the participants could still keep the accuracy of force control after training,although the manipulation tools and the target materials had changed.And this result provides the foundation for the improved force skill transfer.
