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

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.
