For the assessment of physical activity, motion sensors have become increasingly important. To assure a high accuracy of the generated sensor data, the measurement error of these devices needs to be determined. Sensor variability has been assessed with various types of mechanical shakers. We conducted a small feasibility study to explore if a programmable robotic arm can be a suitable tool for the assessment of variability between different accelerometers (inter-device variability). We compared the output of the accelerometers GT1M and GT3X (both ActiGraph) and RT3 (Stayhealthy) for two different movement sequences.
对于身体活动的评估而言，运动传感器已变得愈发重要。为确保所生成传感器数据的高精度，需要确定这些设备的测量误差。已使用各种类型的机械振动台评估了传感器的变异性。我们开展了一项小型可行性研究，以探究可编程机器人手臂是否可作为评估不同加速度计之间变异性（设备间变异性）的合适工具。我们针对两种不同的运动序列比较了加速度计GT1M和GT3X（均为ActiGraph品牌）以及RT3（Stayhealthy品牌）的输出。
