    摘要： A system and method are described herein for a sensor device which biomechanically detects in real-time a user's movement state and posture and then provides real-time feedback to the user based on the user's real-time posture. The feedback is provided through immediate sensory feedback through the sensor device (e.g., a sound or vibration) as well as through an avatar within an associated application with which the sensor device communicates. The sensor device detects the user's movement state and posture by capturing data from a tri-axial accelerometer in the sensor device. Streamed data from the accelerometer is normalized to correct for sensor errors as well as variations in sensor placement and orientation. Normalization is based on accelerometer data collected while the user is wearing the device and performing specific actions.

    摘要翻译： 本文描述了一种用于生物力学地实时检测用户的运动状态和姿势并且然后基于用户的实时姿势向用户提供实时反馈的传感器设备的系统和方法。 反馈通过传感器装置的即时感觉反馈（例如，声音或振动）以及通过与传感器装置通信的相关应用中的化身来提供。 传感器装置通过从传感器装置中的三轴加速度计捕获数据来检测用户的运动状态和姿势。 来自加速度计的流数据被归一化以校正传感器误差以及传感器位置和方向的变化。 归一化是基于在用户佩戴设备并执行特定动作时收集的加速度计数据。
