Input Devices

Paper Summary:

This paper discusses how computers would be useless without input devices and how even small-scale computers, including calculators and GPS navigation systems, require some input from the human being in order to work properly and produce worthwhile output. It examines how some of the everyday input devices, like keyboards, mice, joysticks, and microphones, have reached increasingly more sophisticated levels of technology. It also shows how other input devices that are available to the general public, but are generally used in commercial settings, include touch-screens, keypads for ATMs and bank card purchases, credit card scanners, bar code readers, and more.

From the Paper:

"The portable navigation systems currently out on the market are very helpful for drivers, hikers, and campers. They usually require the user to input coordinates in a cumbersome manner, by scrolling down a list and manually inputting navigational points of reference. This tedious process has been recently made more streamlined by the introduction of the touch screen GPS system. However, this is really no different from the technology used for touch screen computers; the difference is in the output of the computer in this case."
