專利摘要(中)
一種基於步態分析的不平衡預警方法利用穿戴於用戶的肢體部位且包含慣性測量單元、處理單元和輸出單元的穿戴裝置來執行，並包含：該處理單元根據該慣性測量單元在用戶連續行走多步期間獲得的加速度資料，獲得對應於該用戶的晃動角度閾值；該處理單元根據該慣性測量單元在該用戶行進時獲得的角速度資料，計算出該肢體部位在每一單位時間內的晃動角度；及該處理單元判定該晃動角度是否大於該晃動角度閾值，並在判定出該晃動角度大於該晃動角度閾值時，使該輸出單元產生用於指示不平衡的警示輸出。

專利摘要(英)
A gait analysis-based imbalance early-warning method is performed using a wearable device, which is worn on the user’s limb part and includes an inertial measurement unit, a processing unit and an output unit, and includes: the processing unit obtaining a perturbation angle threshold corresponding to the user based on acceleration data that is obtained by the inertial measurement unit during continuous multi-step walking of the user; the processing unit calculating a perturbation angle of the user’s limb part per unit time based on angular velocity data obtained by the inertial measurement unit while the user is traveling; and the processing unit determining whether the perturbation angle is greater than the perturbation angle threshold, and causing the output unit to generate a warning output for indicating imbalance when it is determined that the perturbation angle is greater than the perturbation angle threshold.
