Hi

To use hand-tracking feature, do I need extra hardware?
or the glasses uses some integrated sensor like infrared or a camera?

Thanks!

Hand Tracking is only available on Xreal Light, the Airs cant do it unfortunately

Hi, the hand-tracking function is only supported by XREAL Light. And the feature is enabled by the SDK and realized by the CV cams on Light glass.
