I’ve written an application to help people using the Playstation Eye camera easily figure out what lens they need for their particular setup.

It’s pretty simple to use, just input your distance from the camera to the touch surface (typically the image plane), the image’s horizontal and/or vertical dimensions and you’ll see which lens you need.  The mm number is the focal length of the lens, typically for an m12 lens mount setup, or CS if you’re using one of the Peau Productions CS lens mounts.

Application is Windows .exe only.  Porting to Silverlight for web deployment soon.

Download here or attached.

Attached is a screenshot of the application.

Any questions/suggestions are welcome.

this looks great… much more straight forward than the confusing Excel spreadsheets that have been going around

This is awesome great job on your first project Peau keep em coming

the result given by the software [ Lens (mm) ] is the minimum lens focal lenght you must have in order to see the image.

example quoted from PeauProduction answer to my question:
if the software returns 2.46 mm as result you can get any lens above that and the image you want to track will be seen.Go for the 2.5mm lens for example if you are getting 2.46mm.  That lens will have some distortion so be aware of that.

Hope this can help somebody else!
thanks, byebye

I need to clarify something, I’m assuming width is from left to right for the table and height from where you are standing to the other end. Had a “discussion” about this with a friend as to which way it’s being calculated.

Also, is it correct to say that the larger the image is on the table, the lower the lens mm becomes?

The lens calculator app asks for the Image Width (left to right) and Image Length (top to bottom).  The Distance/Height value should be the distance from the end of the camera lens to the top of your touch surface.  The lower the focal length mm of the lens the wider a field of view (FOV) the lens has, so yes it will see a wider/larger image then.
