论文摘要
每年，我们都会更加依赖可穿戴设备来收集个性化数据，例如我们的运动，心率，呼吸等。为了捕获这些数据，设备包含传感器，例如加速度计和陀螺仪，这些传感器能够衡量其周围环境的变化并通过信息传递，并通过信息传递。尽管这些传感器在不同的设备中的行为应该类似，但并非总是如此。在此案例研究中，我们分析了来自三个不同设备的加速度计，以记录相同的动作，以确定差异是否是由于设备内部或设备之间的可变性所致。我们发现具有不同规格的设备（例如灵敏度和采样频率）之间的最显着变化。然而，即使从同一人，活动和传感器类型收集数据的情况下，也应假定数据的差异。
Every year we grow more dependent on wearable devices to gather personalized data, such as our movements, heart rate, respiration, etc. To capture this data, devices contain sensors, such as accelerometers and gyroscopes, that are able to measure changes in their surroundings and pass along the information for better informed decisions. Although these sensors should behave similarly in different devices, that is not always the case. In this case study, we analyze accelerometers from three different devices recording the same actions with an aim to determine whether the discrepancies are due to variability within or between devices. We found the most significant variation between devices with different specifications, such as sensitivity and sampling frequency. Nevertheless, variance in the data should be assumed, even if data is gathered from the same person, activity, and type of sensor.
