QANTAS introduced a full touch screen system for check-in by CSAs way back before they offloaded most of that stuff back onto the customer. It was a nightmare. Most of the testing was done by pencil heads that chewed their nails (not really but the UAT was pretty minimal) & when the (predominantly female) CSAs started using it with long fingernails & jewellry the screens were scratched up pretty quick. After a few months the physical/medical problems started appearing. They had to do a full 180 & redesign it for key-strokes.
