If you'll notice at the end of that video, the projector seems quite bright. If it is effecting the user's vision, a pattern could be because of eye motion, not the actual pattern projected.
I worry permanent effects of bright IR sources myself... I tend to avoid looking at Sick or Velodyne scanners when I'm around them too.

For comparison, here's a youtube video of the dots the Kinect projects. http://www.youtube.com/watch?v=sM2-JQtd2Oc&feature=relat...
I think the "test pattern" is in the poster's imagination.

Lidar scanners use IR lasers. AFAIK the Kinect uses IR LED which wouldn't be nearly as harmful.
