Pressure sensitive shoulders?

Don't know if this is expensive or worth it, but as most controllers seem to have analogue shoulder buttons, would it be possible and cost efficient to maybe use some pressure senstive buttons on the shoulders - that way you don't need any mechanical bits for the analogue aspect, but you'd still make it available.

Or maybe could put something like this between the electic switch and the plastic button:

Then you'd still get the digital button press, as well as a pressure reading.

I'm not sure I'd use such a feature, but thought I'd maybe throw the idea out there
 
Strafing and on racing games, this could be useful. I think this would be a nice feature too
 
Now it seems the Pyra will be very good for Dreamcast emulation, it'd certainly make game play much more authentic!
 
I would certainly not object to analogue shoulders, I've become quite used to them on GameCube racing games, but would it not add yet more complexity to the buttons that we are having difficulty with?
 
But the devices in the link you posted earlier are varistors, or voltage dependent resistors. Not pressure sensitive ones.

You're right, they are varistors according to their datasheets. Chinese suppliers list them as piezoresistors, though by definition they clearly are not. I didn't even notice a few of them being labeled as varistors.
 
Well, there are some pretty small piezoresistors: http://www.aliexpress.com/w/wholesale-piezoresistor.html
Even is size does not matter, the signal has to be wired to the soc, with the port its currently wired to, may not beeing a capable interface.
The left side is a bit more problematic but on the right side you could just jam a tiny little ADC in there. I haven't followed the traces but they could even meet up at some point where there's room for a dual ADC.

Ah ok then, I thought the whole point of this was to have a solution that does not require changeing the board layout, as ED already mentioned some weeks ago that layout alterations aren't possible anymore

Oh sorry, I had forgotten about that.
