Monado's hand tracking: hand-waving our way towards a first attempt

May 31, 2022 by Moses Turner  |   Blog

Optical hand tracking for XR has a bit of a reputation - getting training data, training neural nets, and deploying them in real-time, low-latency environments such as XR is every bit as hard as they say it is.
