Abstract

This paper presents a measurement system intended to monitor the usage of walker assistive devices. The goal is to guide the user in the correct use of the device in order to prevent risky situations and maximize comfort. Two risk indicators are defined: one related to force unbalance and the other related to motor incoordination. Force unbalance is measured by load cells attached to the walker legs, while motor incoordination is estimated by synchronizing force measurements with distance data provided by an optical sensor. The measurement system is equipped with a Bluetooth link that enables local supervision on a computer or tablet. Calibration and experimental results are included in the paper.

摘要

本文介绍了一种旨在监测助行器辅助设备使用情况的测量系统。其目标是指导用户正确使用该设备，以防止危险情况发生并最大限度地提高舒适度。定义了两个风险指标：一个与力不平衡有关，另一个与运动不协调有关。力不平衡通过连接在助行器腿部的测力传感器进行测量，而运动不协调则通过将力测量与光学传感器提供的距离数据同步来估计。该测量系统配备了蓝牙链接，可在计算机或平板电脑上进行本地监控。本文还包括了校准和实验结果。
