openness on the device (which keeps it from being a proper smartphone
- the whole you get to install your own applications on it), typing
on a screen is annoyingly slow. I'm not so sure you can really
create muscle memory properly there.
Nuff said?
This really shouldn't be too hard to implement these days.
Just have another layer immediately above the lcd, perhaps beneath a
sheet of plastic, that moves slightly when an electric signal is
applied, for instance piezoelectrically.
so you draw a raised ridge around each virtual key, and you pop the
center of the key up slightly when it is touched long enough to be
pressed.
Is that too much to ask for?
