摘 要:盲人出行问题一直是社会热点,大多盲人在外出时都存在摔倒的风险。文章通过对盲人出行现状进行调查,并研究了一种防摔倒监控智能盲杖。该系统通过传感器、压感器、陀螺仪来检测盲人当前运动状态以及是否摔倒。具体涉及了 Sports biomechanics、AI、HI,利用多元传感人体运动学、生理学模型预测跌倒时的运动系数,减少盲人受到的伤害。精准检测摔落运动和预警成为关键。随着研究的不断深入,智能导盲杖的面世将为新兴医疗设施发展奠定基础。

Abstract: The problem of the blind travel has always been a social hotspot. Most blind people are at risk of falling when they go out. This paper investigates the current situation of blind people's travel, and studies an intelligent blind stick for fall prevention and monitoring. The system uses sensors, pressure sensors and gyroscopes to detect the current movement state of the blind and whether they fall. It involves specifically Sports biomechanics, AI and HI. Multi sensor human kinematics and physiology models are used to predict the motion coefficient when falling, so as to reduce the injury caused to the blind. Accurate detection of falling movement and early warning become the key. With the deepening of research, the advent of intelligent guide blind stick will lay the foundation for the development of emerging medical facilities.
