In this study vibrotactile stimulation of the upper leg and its usability for feedback was tested. Three experiments were performed on ten healthy subjects using pager motors. The first experiment was to test the perception of the vibration at different frequencies and at different locations of the upper leg. The second experiment tested the ability of subjects to estimate location and number of stimuli in an array. In addition it was evaluated whether simultaneous or sequential stimulation is better interpretable. Thirdly the habituation of the vibration was determined. The experiments showed that vibrotactile stimulation is well perceived and can be useful in providing feedback on the upper leg. Further experiments are needed to determine the effectiveness of vibrotactile stimulation for feedback in trans-femoral prostheses.
在本研究中，测试了对大腿的振动触觉刺激及其反馈可用性。使用传呼机电机对10名健康受试者进行了三项实验。第一个实验是测试在大腿不同频率和不同位置对振动的感知。第二个实验测试了受试者估计阵列中刺激位置和数量的能力。此外，还评估了同时刺激或顺序刺激是否更易于解读。第三，确定了振动的适应性。实验表明，振动触觉刺激能被很好地感知，并且在提供大腿反馈方面可能有用。需要进一步的实验来确定振动触觉刺激在经股骨假肢反馈中的有效性。
