+In this tutorial, we extend an input scenario called [Put that there](href:https://youtu.be/CbIn8p4_4CQ) dating back to research from the MIT Media Lab in the early 1980's with eye, hand and voice input.
 The idea is simple: Benefit from your eyes for fast target selection and positioning. 
-If refinement is required, use additional input from your hands, voice or controllers. 
+Simply look at a hologram and say _'put this'_, look over where you want to place it and say _'there!'_. 
+For more precisely positionig your hologram, you can use additional input from your hands, voice or controllers.
