我们提出了一种新的方法，用于提供一个触觉的感觉，在步态过程中的脚趾垫的触觉错觉。我们的方法扩展了以前在指垫中描述的错觉，其中当手指垫与表面接触时向指甲呈现振动时引起触觉。在初步测试中，我们定性地证实，错觉可以诱导在脚趾垫与一定程度的强度的振动和脚趾力施加到表面。在实验中，我们用心理物理学的方法定量地测量了在恒定振动强度下诱导错觉的最小力。结果显示，平均需要326 gf的力才能产生错觉。此外，非正式测试表明，力与趾垫的温度呈负相关。
We present a novel method for providing a tactile sensations using a tactile illusion in the toe pad during gait. Our method extends an illusion previously described in the finger pad, in which tactile sensations were induced when a vibration was presented to the fingernail while the finger pad was in contact with a surface. In Preliminary test, we qualitatively confirmed that the illusion could be induced in the toe pad with a certain level of intensity of vibration and toe force applied to the surface. In Experiment, we quantitatively measured the minimum force for inducing the illusion with constant vibration intensity using a psychophysical approach. The results revealed that an average force of 326 gf was required to induce the illusion. In addition, informal testing suggested that force was negatively correlated with the temperature of the toe pad.
