Accidental slips and falls due to decreased strength and stability are a concern for the elderly. A method to detect and ideally predict these falls can reduce their occurrence and allow these individuals to regain a degree of independence. This paper presents the design and assessment of a wireless, wearable device that continuously samples accelerometer and gyroscope data with a goal to detect and predict falls. Lyapunov-based analyses of these time series data indicate that wearer instability can be detected and predicted in real time, implying the ability to predict impending incidents.
由于力量和稳定性下降导致的意外滑倒和跌倒对老年人来说是一个问题。一种检测并理想地预测这些跌倒的方法可以减少其发生,并使这些人重新获得一定程度的独立性。本文介绍了一种无线可穿戴设备的设计和评估,该设备以检测和预测跌倒为目标,持续采集加速度计和陀螺仪数据。对这些时间序列数据进行的基于李雅普诺夫的分析表明,可以实时检测和预测佩戴者的不稳定性,这意味着有能力预测即将发生的事件。
