The instruction SetIVCAMFilterOption can apparently increase the range of depth perception of the SR300 up to 4m.
I suspect that it would be more effective for segmentation than person tracking though, as it seems to primarily apply to depth perception rather than extending the range of hand and face tracking.
I have always wondered if the camera's visual range would be increased if a telescopic lens, like a photography camera zoom lens, were attached to the front of the camera. One would think that so long as the laser light could pass straight through the zoom lens unobstructed then it might still be able to perceive the world in 3D in the same way that it usually does, tricking it into thinking the zoomed image it sees is within the SR300's normal 1.5 m tracking range. I've never had the opportunity to try this experiment though. .
I found in previous experiments that the hand and face tracking does not recognize if you hold up a flat piece of paper with a picture of hands and faces on and move it around, so it definitely needs a real three-dimensional view.
