Android 磨损:传感器类型未描述

Android wear: sensortypes not described

我的 android 穿戴 LG Wear 中有几个传感器 android 文档中没有描述:

传感器名称:AMD,型号:33171006
传感器名称:RMD,传感器类型:33171007
传感器名称:基本手势,传感器类型:33171000
传感器名称:面向,传感器类型:33171002
传感器名称:倾斜,传感器类型:33171003
传感器名称:计步器,传感器类型:33171009
传感器名称:TiltWakeUp,传感器类型:65536
传感器名称:pixart_ppg,传感器类型:33171018
传感器名称:pixart_ppg_raw,传感器类型:33171017

有人可以了解更多吗?

我猜AMD是绝对运动检测(AMD),RMD是相对运动检测(RMD)。

Absolute Motion Detection (AMD): This feature will report the absolute motion state when the device is disturbed from a state of complete rest or no motion. A device on the dash of a moving car will report that the device is in motion.

Relative Motion Detection (RMD): This feature will report the motion state relative to the environment of the device. A device on the dash of a moving car will report that the device is at rest relative to the vehicle.

Activity Recognition: This feature is not included in this SDK release, but will be included in an update release. It provides classifications of the motion state that includes Stationary, Vehicle, Walk, and Run.

这些传感器采用 Snapdragon 芯片。
