Detailed Description

Event registration helpers for the IMU subsystem.

Use this API to subscribe to IMU updates and gesture notifications. Two callback styles are supported:

• Object listeners (ImuEventListener*)
• Static/free function callbacks (function pointers)

Threading notes:

• Callbacks may be invoked from an internal worker/event thread.
