Displays CYRAQ™ 21
4 Touchscreen
Touchscreens are the ultimate human/machine interface. In a touchscreen system,
touching what you see onscreen makes the computer respond. The touchscreen system is
logical, intuitive and simple. Using touchscreens, workers can precisely control
complicated processes without being tethered to a keyboard and mouse. People who have
never used a computer before can immediately interact successfully with a touchscreen-
based computer system allowing airline customers to access flight information, CNC
machinists to quickly change programs, and wait staff can instantly send your order to the
kitchen—all with the touch of their finger.
