We adapted a commercial bathroom scale in order to acquire the raw data from the weight sensors and then to send them to a server via a mobile phone. We investigated the usability and acceptability of the device in a long-term experiment with 22 elderly users that produced more than 5000 weight recordings. Four basic variables were extracted from the vertical force measurements and the stabilogram. The technology was accepted unreservedly, presumably because it did not differ from devices usually encountered in the home. The quantitative results showed a high variability of day-to-day measurement, which was countered by taking a moving average. A balance index was able to identify changes in balance over time. The preliminary results appear promising.
我们对一款商用浴室磅秤进行了改造，以便从称重传感器获取原始数据，然后通过手机将其发送到服务器。我们在一项为期 22 名老年用户的长期实验中对该设备的可用性和可接受性进行了研究，该实验共产生了 5000 多次称重记录。我们从垂直力测量值和平衡图中提取了四个基本变量。这项技术被完全接受，可能是因为它与人们在家中通常遇到的设备没有区别。定量结果显示，日常测量的可变性很高，通过取移动平均值可以抵消这种可变性。平衡指数能够识别随时间推移的平衡变化。初步结果看起来很有前景。
