title: What is Kinect + Linux being used for?
body: <p>An <a href="https://hackaday.com/2018/02/18/rejecting-microsofts-phaseout-of-the-kinect/" rel="nofollow noreferrer">article</a> on Hackaday piqued my curiosity, and I see Kinect + Linux questions being asked here (mostly about configuration), so I'll venture this question:</p>
  
  <p>It is clear to me that Kinect <em>can</em> be used together with Linux on a "regular pc" -- but I can't help wondering <em>why</em>, that is, what might you actually use this for?</p>
  
  <p>I don't suppose people <em>really</em> like the human/computer interface presented in movies such as "Minority Report" -- surely, nobody is <em>actually</em> doing text editing, coding, or business data processing by "hand-waving". So besides just games &amp; exercises, <strong>what are examples of actual, real-world, <em>useful</em> (ie. 'professional') applications of such a setup?</strong></p>
  
  <p>For instance, can it be used for 3D scanning of real-world objects to obtain digital models? What sort of accuracy would such a scan yield?</p>
