Custom MARKER-LESS HAND TRACKING Unity Library
This library can tracking hand and joints just with mobile camera image (no dedicated hardware required like leap motion)
Though hand tracking is considered as one of top and unique ways of interacting with virtual objects in mobile AR, There were no open sourced or at least one time price SDKs available for unity devs to incorporate hand tracking solutions to their projects.
After we finished up with face tracking SDK that covers all iOS devices in the market(works in non ARKit supported devices too)
We started working on a marker less hand tracking tech and found that the vision already offers hand tracking and 21 2D keypoints as well. So We decided to leverage that and write unity version of that and open source it. So Unity devs can directly incorporate hand tracking into their AR projects.
