1. A device comprising:

  • a processing system;

    a radar-based detection component implemented at least partially in hardware, the radar-based detection component comprising;

    a radar-emitting element for transmitting a radar field;

    an antenna for receiving an incoming radio frequency (RF) signal generated by the radar field reflecting off target objects; and

    a pipeline for processing the incoming RF signal to identify information about the target objects;

    multiple applications maintained in computer-readable storage media and executable by the processing system to perform a plurality of operations; and

    multiple gesture sensor Application Programming Interfaces (APIs) maintained in the computer-readable storage media and configured to provide a programmatic interface between the applications and the radar-based detection component, the gesture sensor APIs configured to grant the applications mid-level or high-level access to the radar-based detection component to enable the applications to;

    configure at least one of a digital signal processing stage of the pipeline of the radar-based detection component, a machine-learning stage of the pipeline of the radar-based detection component, or the radar field of the radar-based detection component via the mid-level or high-level access to the radar-based detection component granted by the gesture sensor APIs based on a first operating context associated with a first application of the applications;

    acquire, by the first application and via the gesture sensor APIs, first information from the radar-based detection component, the first information associated with a first target object; and

    reconfigure at least one of the digital signal processing stage of the pipeline of the radar-based detection component, the machine-learning stage of the pipeline of the radar-based detection component, or the radar field of the radar-based detection component via the mid-level or high-level access to the radar-based detection component granted by the gesture sensor APIs based on a second operating context associated with a second application of the applications, the reconfiguring enabling the device to acquire second information associated with a second target object from the radar-based detection component.
