近四十年来，皮质神经假体研究者的目标是开发一种实用的皮质内视觉假体装置。虽然这样一个系统的概念似乎很简单，但其配置的细节仍然没有定义。人类视觉系统将如何响应人工诱导的基于视觉的输入的知识是稀疏的。结合技术限制，这些阻碍了开发实用的皮质内视觉假体装置的进展。本研究的长期目标是开发一种可持续佩戴的皮质内视觉假体装置。早期的研究使用了相对少量的皮层电极，这些电极不足以产生完整的视觉感知。手术困难也使问题复杂化。原型视觉假体系统需要适应不同的刺激，图像处理和用户界面的需求。它还具有明显的便携性要求，这意味着极低的功耗和重量轻，使系统可以在实验室的限制之外使用。我们认为，现有技术已经足够先进，可以开发出第一代皮质内视觉假体装置。在本文中，我们提出了一些解决方案的挑战，开发这种视觉假体设备使用现有的技术
The goal of cortical neuroprosthesis researchers of last four decades is to develop a practical intracortical visual prosthesis device. Although the concept of such a system seems straightforward, details of its configuration remain undefined. Knowledge of how the human visual system will respond to artificially-induced visually-based input is sparse. Combined with technological limitations, these have hindered the progress in developing a practical intracortical visual prosthesis device. The long-term objective of this research is to develop a continuously wearable intracortical visual prosthesis device. Earlier studies have used relatively small numbers of cortical electrodes, and these have been insufficient to generate an integrated visual perception. Surgical difficulties also complicate problem. A prototype visual prosthesis system needs to be adaptable to varying stimulation, image processing, and user interface needs. It also has the obvious requirement portability, implying extremely low power consumption and low weight so that the system can be used outside the confinement of a lab. We feel that available technology has sufficiently advanced to develop a first-generation intracortical visual prosthesis device. In this paper we propose some solutions to the challenges for developing this visual prosthesis device using existing technologies
