Hi Leigh, Microsoft Surface is excellent at this. It uses completely different technology but may provide inspiration. http://www.microsoft.com/surface/
The ipad only has a capacitive touch screen. You'll have to find out how many touch points the hw/sw can track at once which is documented somewhere, or by experimentation. Assuming it's 10, you could have 2 flat objects placed on the screen with unique 5 point signatures (dots) and write the SW to detect their position and orientation quite easily (public API though?). The dots would use the same material as on the tip of home-made ipad stylus kits you'll find searching google. Try using some card with dots on it. Sounds like an interesting project. I'm looking forward to seeing your demo on techmeme, if you're the first. cheers, Jeromy Evans On Feb 6, 2:20 pm, traveltikes <[email protected]> wrote: > Hi all, I want to detect a number of unique objects on an ipad and > then track their movement, how would I go about it??? > > shape recognition on the placement signature of the object? > using a unique array of 'protrusions' on the base of the object which > creates its own unique signature or footprint? > > Thoughts or suggestions.
