1. An apparatus comprising:
a radar system that detects radar-based gestures on behalf of application subscribers;
an inertial measurement unit that produces inertial data; and
a state machine configured to transition between multiple states for controlling the radar system based on the inertial data and one or more context-sensitive transition functions, the multiple states including:
a no-gating state in which the state machine enables the radar system to output indications of the radar-based gestures to the application subscribers; and
a soft-gating state in which the radar system is prevented from outputting the indications of the radar-based gestures to one or more of the application subscribers by shielding a gesture-recognition model from radar data collected by the radar system.
