> Years ago a pal and I installed a system for the Secret Service that had thousands of very expensive switches on panels in a control room. We battled with a unique set of bounce challenges because the uniformed officers were too lazy to stand up and press a button. They tossed rulers at the panels from across the room. Different impacts created quite an array of bouncing.
It's impossible to guess how users will use a system until they can be observed in the wild.
This probably induced a lot of Object Thrown Operation (OTO) once word spread to everyone -- not just the lazy -- that it was possible to activate the buttons from afar.
