目标。脑机接口(BMI)研究的主要目标之一是恢复瘫痪患者的功能。目前，基于不同的输入模式(外部应用和手术植入的传感器)和输出模式(例如，计算机系统、假肢和功能性电刺激系统的控制)的多个BMI设计特征正在被研究。虽然这些技术最终可能会提供一定程度的好处，但它们都给最终用户带来了相关的负担。考虑到目前与使用每种系统相关的负担，我们试图评估瘫痪患者对使用各种技术来实现特定好处的态度。接近。我们设计并分发了一项技术调查，以确定考虑到目前与脊髓损伤相关的负担，四肢瘫痪患者考虑使用不同技术所需的益处水平。这项调查询问了用户对8项BMI技术的偏好，包括脑电图仪、皮层脑电图仪和皮质内微电极阵列，以及用于比较的商业眼睛跟踪系统。参与者使用5分量表对他们采用这些技术的可能性进行评级，以获得13种潜在的控制能力。主要结果。接受调查的受访者最有可能采用BMI技术来恢复部分自然上肢功能，包括恢复手握力和/或某种程度的自然手臂运动。这些人也对高速打字和控制快速机械臂感兴趣。通过手术植入的无线技术被采用的可能性是有线技术的两倍。意义重大。评估最终用户的偏好是设计和实施任何辅助技术的基本前提。这项调查的结果表明，四肢瘫痪患者会采用一种不引人注目的自主BMI系统来恢复上肢功能和控制外部设备，如通信接口。
Objective. One of the main goals of brain-machine interface (BMI) research is to restore function to people with paralysis. Currently, multiple BMI design features are being investigated, based on various input modalities (externally applied and surgically implantable sensors) and output modalities (e.g. control of computer systems, prosthetic arms, and functional electrical stimulation systems). While these technologies may eventually provide some level of benefit, they each carry associated burdens for end-users. We sought to assess the attitudes of people with paralysis toward using various technologies to achieve particular benefits, given the burdens currently associated with the use of each system. Approach. We designed and distributed a technology survey to determine the level of benefit necessary for people with tetraplegia due to spinal cord injury to consider using different technologies, given the burdens currently associated with them. The survey queried user preferences for 8 BMI technologies including electroencephalography, electrocorticography, and intracortical microelectrode arrays, as well as a commercially available eye tracking system for comparison. Participants used a 5-point scale to rate their likelihood to adopt these technologies for 13 potential control capabilities. Main Results. Survey respondents were most likely to adopt BMI technology to restore some of their natural upper extremity function, including restoration of hand grasp and/or some degree of natural arm movement. High speed typing and control of a fast robot arm were also of interest to this population. Surgically implanted wireless technologies were twice as 'likely' to be adopted as their wired equivalents. Significance. Assessing end-user preferences is an essential prerequisite to the design and implementation of any assistive technology. The results of this survey suggest that people with tetraplegia would adopt an unobtrusive, autonomous BMI system for both restoration of upper extremity function and control of external devices such as communication interfaces.
