本研究旨在通过测量连接到振动装置的 3D 打印接触头的加速度，建立一种量化运动错觉期间肌腱振动的新方法。该接触头的中心设计有一个孔，其中固定有单轴加速度计。此外，头部的上端设计为用螺栓固定在振动器上。这有助于研究接触面积是否影响感知参数，例如运动错觉的强度。第二个加速度计连接到振动器的外部。对于 5 名参与者，右臂（所有参与者的主导侧）的肱二头肌肌腱以 100 Hz 的频率受到刺激 30 秒。以 1000 Hz 的频率记录接触头内部和外部测得的加速度，并计算两个加速度的均方根 (RMS) 值之比。结果显示最大比率为 1.02，最小比率为 0.97。我们得出的结论是，所提出的方法可以将运动错觉期间的肌腱振动量化到%以内。使用 3D 打印机生产接触头提供了一种在这些研究中改变某些参数的便捷方法。在未来的工作中，可以通过修改此设计来改变接触区域的大小，我们将检查接触区域在运动错觉中的效果。预计这将是一种非常有用的技术，可以在虚拟现实中提供动觉。
This study aims to establish a new method for quantifying tendon vibration during motion illusion by measuring the acceleration of a 3D-printed contact head attached to the vibration device. This contact head was designed with a hole in the center in which a single-axis accelerometer was fixed. Moreover, the upper end of the head was designed to be bolted to the vibrator. This aids in investigating whether the contact area influences perceptual parameters such as strength of motion illusion. A second accelerometer was attached to the exterior of the vibrator. For five participants, the biceps brachii tendon of the right arm (the dominant side for all participants) was stimulated for 30 s at 100 Hz. The accelerations measured inside and outside the contact head were recorded at 1000 Hz, and the ratio of root-mean-square (RMS) values of the two accelerations was calculated. The results showed a maximum ratio of 1.02 and a minimum of 0.97. We conclude that the proposed method can quantify tendon vibration during motion illusion to within%. The use of a 3D printer to produce the contact head provides a convenient means of varying some parameters in these investigations. In future work, the size of the contact area could be changed by modifying this design, and we will examine the effect of the contact area in motion illusion. This is expected to be an extremely useful technique to provide a kinesthetic sensation in virtual reality.
