Upper-limb protheses are subject to high rates of abandonment. Prosthesis abandonment is related to a reduced sense of embodiment, the sense of self-location, agency, and ownership that humans feel in relation to their bodies and body parts. If a prosthesis does not evoke a sense of embodiment, users are less likely to view them as useful and integrated with their bodies. Currently, visual feedback is the only option for most prosthesis users to account for their augmented activities. However, for activities of daily living, such as grasping actions, haptic feedback is critically important and may improve sense of embodiment. Therefore, we are investigating how converting natural haptic feedback from the prosthetic fingertips into vibrotactile feedback administered to another location on the body may allow participants to experience haptic feedback and if and how this experience affects embodiment. While we found no differences between our experimental manipulations of feedback type, we found evidence that embodiment was not negatively impacted when switching from natural feedback to proximal vibrotactile feedback. Proximal vibrotactile feedback should be further studied and considered when designing prostheses.

掌握实施例：人造肢体的触觉反馈

上肢假肢容易被遗弃。假体的放弃与人们对自己的身体和身体部位的自我感觉，自我定位，代理和主人翁意识的降低有关。如果假体没有唤起人们的包容性，则用户不太可能将其视为有用的并与他们的身体融为一体。当前，视觉反馈是大多数假肢使用者考虑其增强活动的唯一选择。然而，对于诸如抓握动作之类的日常生活活动，触觉反馈至关重要，并且可以改善体现感。所以，我们正在研究如何将假肢指尖的自然触觉反馈转换为对身体另一位置的震动触觉反馈，从而使参与者体验到触觉反馈，以及这种体验是否以及如何影响实施方式。虽然我们发现反馈类型的实验操作之间没有差异，但我们发现证据表明从自然反馈转换为近端触觉反馈时，实施方式不会受到负面影响。在设计假体时，应进一步研究和考虑近端触觉反馈。
