Lab 3.2 Interaction Devices

Lab Objectives

After this lab, you will be able to:

  • Identify the Range of Input and Output Devices for Interaction

  • Compare the Different Interaction Devices


After understanding human characteristics, we need to turn our attention to computer hardware. We assume readers are familiar with the fundamental computer components of processor, main memory, data buses, hard drive memory, and network connectors. In this lab, we concentrate on the hardware devices used by humans to interact with the computer. Such devices are called interaction devices. Most interaction devices split naturally into input and output peripherals (as viewed from the computer). Input devices predominate, with the occasional example of a peripheral that is both an input and an output device such as the force-feedback joystick.
