While refreshable Braille on a touch screen would be the final goal
for accessibility, I think the OP was talking about mimicking buttons,
which I imagine wouldn't need to be nearly as precise. One 'bump' per
finger-space requires a much smaller resolution than six bumps per
finger-space (as is used in Braille). Mechanical movement is still the
challenge, but reducing the actuators by a factor of 6 is a big help.
