Hi and thanks for the question.
This version of the plugin only supports Meta Quest headsets, however, on request by many of our users we are just now starting to work on a new version of the plugin which will support more headsets. This new version will be sold as a separate plugin which will be likely called Hand Tracking Plugin Pro. We will be posting updates on the progress made on our discord server.
Here you can see the roadmap for the new plugin and here the roadmap for the Hand Tracking Plugin. Before starting work on the Hand Tracking Plugin Pro all we have left to sort out is better documentation for the Hand Tracking Plugin.
