In a strange software twist. Oculus have added Touch Controller support to their setup software. Version 18.104.22.1682257 adds support to set up the Oculus Touch Controllers. However, unless you are a developer with early access to the devices you will be unable to Touch yourself (intended)
The setup will run you through the setup to pair the left and then right controller. If you do not have controllers, you can skip to the next step.
The Oculus Touch controllers will be available sometime in 2016. During the Connect 3 event starting October 5 Oculus have said they will have more to discuss. The timing of this event leads us to believe Oculus may start to ship shortly after that.
