Uh
I just had another idea , I don't know if it helps with that , but just to do with the R_S_I_.  Is it possible , just as an option , when we open it up , people can use their fingers to press the button , or we have inside like a small pointer thing when people want to .
Yeah you could , you could have some sort of stylus that you could pull out
Like one of the palm pop thing.
