IWRL6432AOP: IWRL6432AOP Radar Integration: Feasibility & Software Support for Gesture Recognition and Multi-people tracking Features

Part Number: IWRL6432AOP
Other Parts Discussed in Thread: IWRL6432, , IWR6843

Tool/software:

Hello IWRL6432 Champ!

Customer is planning to add a radar to a set-top box to implement AI features, and I'm wondering if it's possible to include the aforementioned functions individually, or all at once, in the firmware.

Could you please provide your opinion on whether the L6432AOP can support all these functions simultaneously, and if there are any constraints?

The scenarios we want to implement in our project are gesture recognition, people counting, recognition of people's direction of movement, and distance from the sensor.

I'd like to know if these features are feasible with the IWRL6432AOP, and I'd also appreciate it if you could introduce any additional possible solutions.

Thanks.
Best Regards, 
Jack

    Hi Jack,

    It is feasible to perform people counting, recognize direction of travel and distance from the sensor of multiple people all at once with IWRL6432AOP, there of course would be limitations on how many people you could track in a given area with some minimum separation from one another. You could get better performance by using a different device that has more antennas (which means more resolution) such as IWR6843 but IWRL6432AOP can still achieve this functionality. Can you provide more specifics on the range/FOV and number of people you expect to track/count for this application? 

    Gesture recognition can also be done with IWRL6432AOP, we do not have an example that integrates gesture recognition with people tracking. Our individual examples for each application use different processing chains so as they exist currently it couldn't be done at the same time but one could likely implement a mechanism to switch between the two processing chains as needed. However, another limitation you will face for gesture recognition with IWRL6432AOP (but also most radar sensors) is the maximum range at which gestures can be recognized. In the past we have noticed difficulty in reliably detecting gestures beyond about 2m. What is the required range for gesture recognition for your customer's use-case?

    Best regards,

    Josh
