Gesture Recognition for my Grandma (Kinect) Linux

view story

http://stackoverflow.com – I'm looking into making a project with the Kinect to allow my Grandma to control her TV without being daunted by using the remote. So, I've been looking into basic gesture recognition. The aim will be to say turn the volume of the TV up by sending the right IR code to the TV when the program detects that the right hand is being "waved." The problem is, no matter where I look, I can't seem to find a Linux based tutorial which shows how to do something as a result of a gesture. One other thing to note is that I don't need to have any GUI apart from the debug window as this will slow my program (HowTos)
