iPad game using capacitive dials, faders, switches?

I'm reposting from someone who asked this on the Macrumors forums, and thought it would be interesting to get the opinions from some of the more seasoned touchscreen developers.
So, now that we have a device big enough - What's to stop a developer making something akin to this, in an iPad format?



Using capacative controls, the app recognises these being overlaid onto the screen, and then can use their movement to be a control.
At first I couldn't see a way possible for the touchscreen to recognize the objects or an object turning but the OP added a very good suggestion:
Say the person is put on the screen - it has 2 capacative points opposite each other on the underside with a central capacative point. That distance could be used in part to identify a player or piece.

It'd be more complex if the dial itself is moving it's centre whilst you turn it, but i'm sure it's not too hard to work out turning - You do the math for the angle the 2 points are in relation to the centre of the dial.

Wow that is a neat idea. If the ipad supports a very large number of simultaneous touches then this could work really well. Each "gamepiece" could have a unique dot pattern (3 dots minimum).

Yeah, now that I think about it this could work and be implemented really well. Does the iPad still have the 5-touch hardware restriction?

This looks like an interesting idea. The only thing that could ruin it is the whole 5 finger multi-touch limit.

well maybe instead of them running on the touch, maybe it could be like...wifi sensing? they sound out a signal that the iPad then reads and sees where it is and you can tap there now?

I don't think Wi-Fi and Bluetooth can sense distance; maybe to some extent you could check for signal strength but it would be very unreliable.

well maybe an add on to the ipad (seeing as these objects will probably be bought at a store) could be a like sonar somewhat attachment?

Distributing an app to all iPad users is going to be quite simple; however, distributing physical pieces of the right caliber is another story.

OP is right, the idea seems totally possible, and pretty cool at that. Only problem is, the pieces moving across the screen.

No, it depends on the object. For example, pieces made out of sausage would be fine.
