Many point-of-sale machines now are essentially just a smartphone with a card reader attached and the interface. The control layout can change at a moment's notice and there are no physical boundaries between buttons. With a keypad-style machine, the buttons are always in the same place and can be located by touch, especially since the middle button has a raised ridge on it.

Buttons can also be located by touch without activating them, which enables a "locate then press" style of interaction which is not possible on touchscreens, where even light touches will register as presses and the buttons must be located visually rather than by touch.

When elevator or door controls are replaced by touch screens, will existing accessibility features be preserved, or will some people no longer be able to use those controls?

This Fossil Friday, scoot into the weekend with Scutosaurus karpinskii: the “shield lizard.” This large herbivore lived during the Late Permian some 253 million years ago. It’s part of an early group of sauropsids known as pareiasaurs. The pareiasaurs had spikes and thickened knobs around their skulls, as well as peg-like teeth adapted for eating plants. Their fossils have been found in Africa, Europe, and Asia. Spot this one in the Museum’s Hall of Vertebrate Origins!
