This paper deals with the design of systems of sensory substitution of vision in case of blindness. Using the rules of man-machine interactions, one proposes the following optimal design for sensory substitution systems. A model of the visual system might process visual information similarly to its natural counterpart in order to deliver a signal comparable to the one reached in polysensory nervous structures. Then this artificial signal might reach these associative structures through a substitutive sensory system. To achieve this aim, one might model this substitutive system, reverse the information flow, and then trust the natural substitutive system with the stimuli generated by this inverse model. As a result, this artificial system consists of a model of vision connected to an inverse model of the substitutive sensory system. It would first process visual information up to a complex level. Then it would translate this complex signal into coded substitutive stimuli. These stimuli, after processing by the sensory substitutive system, would evoke a vision-like perception.
本文探讨了针对失明情况的视觉感官替代系统的设计。利用人机交互规则，提出了以下感官替代系统的最优设计。视觉系统模型可能以类似于其自然对应物的方式处理视觉信息，以便传递一个与在多感官神经结构中所达到的信号相当的信号。然后，这个人工信号可能通过替代感官系统到达这些联想结构。为实现这一目标，可以对这个替代系统进行建模，反转信息流，然后将由这个逆模型生成的刺激交给自然替代系统。结果，这个人工系统由一个与替代感官系统的逆模型相连的视觉模型组成。它首先会将视觉信息处理到复杂程度。然后它会将这个复杂信号转换为编码的替代刺激。这些刺激在经过感官替代系统处理后，会引发类似视觉的感知。
