    • Disclosed are methods and systems for stabilizing orientation values of an electronic device, the orientation values representing an orientation of the electronic device, the method comprising: obtaining first sensor readings from a first sensor; obtaining second sensor readings from a second sensor; evaluating the first sensor readings and the second sensor readings to determine whether the electronic device is stationary; locking the orientation values when the electronic device is stationary; collecting at least one of further first sensor readings and further second sensor readings while the orientation values are locked; determining whether the orientation of the electronic device is changing by more than a threshold amount based on one or more of the further first sensor readings and the further second sensor readings; and unlocking the orientation values for updating based on the further sensor readings when the orientation of the electronic device is changing by more than the threshold amount.
    • 公开了用于稳定电子设备的取向值的方法和系统,所述取向值表示电子设备的取向,该方法包括:从第一传感器获得第一传感器读数; 从第二传感器获得第二传感器读数; 评估第一传感器读数和第二传感器读数以确定电子设备是否静止; 当电子设备静止时锁定取向值; 在取向值被锁定的同时收集进一步的第一传感器读数和另外的第二传感器读数中的至少一个; 基于所述另外的第一传感器读数和所述另外的第二传感器读数中的一个或多个来确定所述电子设备的取向是否正在改变超过阈值量; 并且当电子设备的方向改变超过阈值量时,基于进一步的传感器读数来解锁用于更新的取向值。
