mmWave Gester Recognition viable distance

Part Number: mmWave

Hi,

I have an application where I would like to detect hand gestures from about 20cm down to 0cm or surface touching. The resolution does not need to be highly precise - perhaps a few mm's worst case. Will the mmWave gesture recognition handle this range? I can't seem to find an answer.

Thanks,

Kevin

    Hi Kevin, 

    Are you referring to the Gesture with Machine Learning Demo for IWR6843 from the Radar Toolbox? If so, this demo is currently configured to detect hand gestures from about ~0.05 m to ~0.30 m. The reason that the minimum range is set to ~0.05m is to ignore any potential coupling effect from the TX/RX antennas. 

    You can try to remove this lower limit by setting the RANGE_BIN_START in gesture.h to 0 (as shown below) then rebuilding the demo.
