The Microsoft HoloLens 2 supports hand tracking of up to 25 joints in the human hand, which can allow for a variety of different gestures and interactions. Fologram’s tracking tools send these joint locations back to grasshopper and enable the live capturing of any hand tracking from a HL2 device. These locations are represented as points in space as a data tree with two branches (one for each hand).
To see a fun example of this in practice, check out this article using hand tracking to view jewelry on your hands in the HoloLens with Fologram.
This example file takes all Connected Devices and connects them to a Track Hands and Track Device component. The outputs in grasshopper show the location in 3D space of the user’s headset and their hands.
