The other advantage of the touch screen/keypad is, it doesn't have to

another ergonomic point to consider, for a microwave or stereo or
any device which might use a touch screen is that, in the case of
devices where the screen is mounted vertically, up and down, one
must bend one's hand into a ver uncomfortable position. A slanted
screen or something mounted horizontally, or perhaps a separate
controling pad, like a remote, seems a better idea.

If your fingers are sensitive enough, you can also often feel the
indentations where one button ends and another begins. Bare in mind
that these are not true touchscreens, they are flat keypads.
Underneath the flat surface is a button that requires minimal force
to activate. A touch screen, by contrast, is a surface that can be
touched on any portion of the screen, and the item at the point you
touched is activated, it is not a flat surface over a few
mechanical buttons. The touchscreen will change depending on the
input required, therefore braille labels are useless on true touch
screens.
