Despite the recent dominance of touchscreens, there is still a big advantage in the tactile feedback which ordinary old buttons provide.

Today’s invention is therefore a calculator with buttons which protrude through a touchscreen surface.

This has the advantage of combining the positive action of buttons, which people like when they are performing finance-related calculations, with the ability to have additional functions described in choosable touchscreen labels on each side of every button.

The buttons could be designed, as shown, to rock both up/down and left/right.
