It would be very helpful if you could provide a input module to use a wand to interact with a Unity Gui (uGUI). Input modules can be derived from e.g. PointerInputModule (see https://bitbucket.org/Unity-Technologies/ui).
What do you think about uGUI? I know that it may not work well in clustered applications but otherwise it would be a nice GUI alternative to MVRs GUI functionality (especially in combination with MarkUX, see http://www.markux.com).
