Abstract

Despite technological advancements, upper limb prostheses still face high abandonment/rejection rates due to limitations in control interfaces and the absence of force/tactile feedback. Improving these aspects is crucial for enhancing user acceptance and optimizing functional performance. This pilot study, therefore, aims to understand which sensory feedback in combination with a soft robotic prosthetic hand could provide advantages for amputees, including performing everyday tasks. Tactile cues provided are contact information, grasping force, degree of hand opening, and combinations of this information. To transfer such feedback, different wearable systems are used, based on either vibrotactile or force stimulation in a non-invasive modality matching approach. Five volunteers with a trans-radial amputation controlling the new prosthetic hand SoftHand Pro performed a study protocol including everyday tasks. The results indicate the preference of amputees for a single, i.e. non-combined, feedback modality. The choice of appropriate haptic feedback seems to be subject and task-specific. Furthermore, in alignment with the participants' feedback, force feedback, with adequate granularity and clarity, could potentially be the most valuable feedback among those presented. Finally, the study suggests that prosthetic solutions should be preferred where amputees are able to choose their feedback system.

上肢修复术中的触觉反馈：跨桡骨截肢不同触觉模式比较的初步研究。

尽管技术进步，但由于控制界面的限制和缺乏力/触觉反馈，上肢假体仍面临较高的废弃率/排斥率。改进这些方面对于提高用户接受度和优化功能性能至关重要。因此，这项试点研究旨在了解哪种感觉反馈与柔软的机器人假手相结合可以为截肢者提供优势，包括执行日常任务。所提供的触觉提示是接触信息、抓握力、手张开的程度以及这些信息的组合。为了传递这种反馈，使用了不同的可穿戴系统，基于非侵入模态匹配方法中的振动触觉或力刺激。五名接受经桡侧截肢手术的志愿者控制着新的假手SoftHand Pro，执行了一项包括日常任务在内的研究方案。结果表明截肢者更喜欢单一的，即非组合的反馈方式。适当的触觉反馈的选择似乎是特定于主题和任务的。此外，与参与者的反馈一致，具有足够粒度和清晰度的力量反馈可能是提出的反馈中最有价值的反馈。最后，该研究表明，在截肢者能够选择反馈系统的情况下，假肢解决方案应该是首选。

期刊介绍： IEEE Transactions on Haptics (ToH) is a scholarly archival journal that addresses the science, technology, and applications associated with information acquisition and object manipulation through touch. Haptic interactions relevant to this journal include all aspects of manual exploration and manipulation of objects by humans, machines and interactions between the two, performed in real, virtual, teleoperated or networked environments. Research areas of relevance to this publication include, but are not limited to, the following topics: Human haptic and multi-sensory perception and action, Aspects of motor control that explicitly pertain to human haptics, Haptic interactions via passive or active tools and machines, Devices that sense, enable, or create haptic interactions locally or at a distance, Haptic rendering and its association with graphic and auditory rendering in virtual reality, Algorithms, controls, and dynamics of haptic devices, users, and interactions between the two, Human-machine performance and safety with haptic feedback, Haptics in the context of human-computer interactions, Systems and networks using haptic devices and interactions, including multi-modal feedback, Application of the above, for example in areas such as education, rehabilitation, medicine, computer-aided design, skills training, computer games, driver controls, simulation, and visualization.
