MACRO-MICRO GESTURE DETECTION

Macro-micro gesture detection is provided. Performance of a macro portion of a macro-micro gesture is detected by a mobile device, using phone-as-a-key (PaaK) sensors of a vehicle, the macro-micro gesture requesting invocation of a function of the vehicle. Using one or more inertial measurement unit (IMU) sensors of the mobile device, performance of a micro portion of the macro-micro gesture is detected. Arbitrating is performed to validate that the function of the vehicle is to be performed in view of performance of both the micro portion and the macro portion. The function of the vehicle is invoked responsive to the validation being successful.
