基于鞋类的可穿戴传感器在监测健康和健康的许多领域变得越来越突出，例如步态和活动监测。在我们之前的研究中，我们介绍了一个基于鞋垫的可穿戴系统SmartStep，它完全集成在一个社会可接受的包装中。从制造的角度来看，SmartStep的电子设备必须为每个鞋码定制，这大大增加了制造过程的复杂性。在这项工作中，我们探索了为SmartStep制作一个通用电子平台的可能性- SmartStep 3.0，它可以在最常见的鞋垫尺寸上使用而无需修改。我们进行了一项人体实验，以比较一种尺寸适合所有人（SmartStep 3.0）和自定义尺寸的SmartStep 2.0之间的准确性。在试点研究中，三名参与者在佩戴SmartStep 2.0和SmartStep 3.0的情况下进行不同的日常生活活动，共收集了约10小时的数据。交叉验证结果显示，SmartStep 2.0的平均准确率为98.5%，而SmartStep 3.0的平均准确率为98.3%，这表明SmartStep 3.0可以和SmartStep 2.0一样准确，同时适合大多数常见的鞋码。
Footwear based wearable sensors are becoming prominent in many areas of monitoring health and wellness, such as gait and activity monitoring. In our previous research we introduced an insole based wearable system SmartStep, which is completely integrated in a socially acceptable package. From a manufacturing perspective, SmartStep's electronics had to be custom made for each shoe size, greatly complicating the manufacturing process. In this work we explore the possibility of making a universal electronics platform for SmartStep - SmartStep 3.0, which can be used in the most common insole sizes without modifications. A pilot human subject experiments were run to compare the accuracy between the one-size fits all (SmartStep 3.0) and custom size SmartStep 2.0. A total of ~10 hours of data was collected in the pilot study involving three participants performing different activities of daily living while wearing SmartStep 2.0 and SmartStep 3.0. Leave one out cross validation resulted in a 98.5% average accuracy from SmartStep 2.0, while SmartStep 3.0 resulted in 98.3% accuracy, suggesting that the SmartStep 3.0 can be as accurate as SmartStep 2.0, while fitting most common shoe sizes.
