Research into sensory substitution systems has expanded, as alternative senses are utilized in real-time to afford object recognition or spatial understanding. Tactile stimulation has long shown promise as a communicatory strategy when applied unobtrusively to the redundant surface areas of the skin. Here, a novel belt, integrating a matrix of macro fiber composites, is purposed to deliver tactile stimuli to the abdomen. The design and development of the belt is presented and a systematic experimental study is conducted to analyze the impact of frequency and duty cycle. The belt is a beta precursor to a soft haptic feedback device that will enable situational awareness and obstacle avoidance through the localization of tactile stimulation relative to a body-centric frame of reference in a local environment.
随着实时利用其他感官来实现物体识别或空间理解，对感官替代系统的研究不断扩展。当将触觉刺激以不显眼的方式应用于皮肤的冗余表面区域时，长期以来它一直显示出作为一种交流策略的潜力。在此，一种集成了宏观纤维复合材料矩阵的新型腰带旨在向腹部传递触觉刺激。本文介绍了该腰带的设计与开发，并进行了系统的实验研究以分析频率和占空比的影响。该腰带是一种软触觉反馈设备的雏形，它将通过相对于局部环境中以身体为中心的参考系定位触觉刺激来实现态势感知和避障。
