近年来，人类增强引起了人们的广泛关注。运动增强是人类增强的一种类型，它使感知到的运动比现实中更大，并且它可以用于各种应用，例如中风患者的运动功能康复和虚拟现实（VR）中更逼真的体验，例如重定向行走（RDW）。然而，随着增强的运动变得比真实的运动更大，伴随的各种感觉将与从躯体感觉感知的感觉更加不一致，这将引起严重的不适感。为了解决这个问题，我们专注于动觉错觉，这是一种心理现象，一个人感觉好像他或她自己的身体在移动。动觉错觉有望填补预期的增强运动和感知的物理运动之间的差距。然而，还没有探索当用户在VR中自愿移动他们的肢体时是否产生以及产生多大的动觉错觉。为了扩展有关动觉错觉的知识，我们进行了两项用户研究，探讨肌腱振动和视觉刺激对动觉错觉的影响。第一个实验证实，感知肘角变得大于实际角度时，肌腱振动。第二个实验表明，当同时呈现肌腱振动和视觉刺激时，感知的肘部角度增加约20度，而当仅呈现视觉刺激时，感知的肘部角度增加约10度。通过这些实验，已经证实，结合肌腱振动和视觉刺激增强了动觉错觉。
In recent years, human augmentation has attracted much attention. One type of human augmentation, motion augmentation makes perceived motion larger than in reality, and it can be used for a variety of applications such as rehabilitation of motor functions of stroke patients and a more realistic experience in virtual reality (VR) such as redirected walking (RDW). However, as augmented motion becomes larger than the real motion, a variety of senses that accompany will be more inconsistent with those perceived from somatic sensations, which will cause a severe sense of discomfort. To address the problem, we focus on kinesthetic illusions that are psychological phenomena where a person feels as if his or her own body is moving. Kinesthetic illusions are expected to fill the gap between the intended augmented motion and perceived physical motion. However, it has not been explored if and how large kinesthetic illusions are produced while a user is moving their limbs voluntarily in VR. To expand the knowledge on kinesthetic illusions, we have conducted two user studies on the impact of tendon vibration and visual stimuli on kinesthetic illusions. First experiment confirmed that the perceived elbow angle becomes larger than the actual angle when presented with tendon vibration. Second experiment revealed that the increase of the perceived elbow angle was about 20 degrees when both tendon vibration and visual stimuli were presented whereas it was about 10 degrees when only visual stimuli were presented. Through these experiments, it has been confirmed that combining tendon vibration and visual stimulation enhances kinesthetic illusions.
