Being a operative system related Q&A site we normally deal with questions that involve hardware support for the platform.
The question linked presents 3 points:
- Is the Kinect controller supported under Ubuntu (can you make it do anything)?
- Can you play Kinect games in Ubuntu?
- Is there any software or plans for software development using the Kinect as a controller?
The first point is on-topic, being an operative system questions about hardware support are common and are accepted as valid. This point can even be answered with a question already existing in Ask Ubuntu:
The second point is a bit far fetched since there are no Kinect games for Windows (as far as I know) that could possibly be emulated in Ubuntu. Still does not make it that much off topic, we get questions all the time with "Is *random stuff the user wants to do*
possible using Ubuntu?". They are not really high quality questions, but can easily answered.
The 3rd point is always valid when talking about a community that has learned to create, develop and support out of the ordinary projects. It is amazing the amount of small niches you will find if you dig hard. There is a high change that some group of people is actually developing and having fun while programming applications that use Kinect in any way. I would not expect something commercial or fancy, but probably exists.
I know this is not a great question, it is a bit speculative on the content and wont make the delights of a mind eager for challenge but some moderator thought it was still a valid question and declined your flag. I have to agree with him.
Since the question can be answered, will not involve opinion, debate, arguments, polling or extended discussion it seems reasonable that it stays.
