I have made a Kinect application, a gesture based picture viewer and it detects humans fine(Obviously it does!) What I wanted to try was (lazy as I am), to see if I could use some (say, voice) command to tell the Nao to do a Swipe Right gesture and have my application identify that gesture. The Nao can easily identify my command and do some gesture. The problem however is, when I put the Nao in front of the Kinect sensor, the Kinect does not track it.
What I want to know is, are there some basics behind Kinect's human body motion tracking that essentially fails when a robot is placed in front of it instead of a human?
PS: I have kept the Nao at the right distance from the sensor. I have also checked if the entire robot is in the field of view of the sensor.
