Hi Arati,

If you'd like to drop me an email with a specific BBC contact query, I'll do 
what i can to help.  I'll need details though, about who you are, what you 
want, and who you'd like to talk to.  This is a big organisation, and it's not 
always easy to put the right people in touch,

Thanks,

Ant

I am wondering if them Kinect things are really working a lot  
simpler; and after waking up in the middle of a shower am now  
postulating that:


1.	They have a simple static laser interference pattern (e.g. akin  
to [1] or those

star projectors you can buy from street vendors).

2.	However this one is very very fine and nicely randomish. i.e.  
dots less than a few

mm appart.

3.	They use a crappy low resolution normal monochrome web cam; with  
a black bit of glass so

only IR gets let through.

4.  They simply pass the image of this camera back.

The reason that this works is that every 'pixel' at CCD level for  
distances of working range will have 1 to 100 or so 'tiny dots' on  
it - depending on the distance it is at. Which is why we have  
roughly the range we get; why we have such a near perfect 1/sigma  
callibration curve and why the range of values you get it so odd -  
and why they filter certain types of noise so badly.


And perhaps, perhaps:

5.	They do a phase locked loop amplifier loop in software by  
flashing the projector.


But I doubt that given the noise/error artifacts.

And that is really all there is to it. Anyone here with a good high- 
res SRL which can do enough IR detection to check if indeed this is  
the case ? I guess a fun test would be to use a mirror to project a  
few extra pixels onto a flat area - and see if that area suddenly  
jumps 'forward'.
