This reference design showcases natural gesture recognition and presence detection with the Processor SDK Linux running on the Sitara AM335x processor: and the mmWave SDK running on the IWR6843ISK.The design demonstrates the functionality of a gesture controlled HMI (Human Machine Interface) where the mmWave sensor detects presence and classifies natural hand gestures and sends them to the Sitara AM335x processor which uses this information to drive the GUI application running under Linux. The design integrates enhanced processor SOCs: sensors and builds an embedded gesture controlled HMI.
