Question: 1 / 400

Which of the following can function as an input device?

Printer

Microphone

Switch Array

A switch array functions as an input device because it allows users to send commands or data to a computer or assistive technology by pressing buttons or switches. These devices are particularly beneficial for individuals with mobility impairments, as they can be operated using various methods such as head movements or eye gaze, depending on the configuration. This input capability makes them crucial in assistive technology settings, enabling users to interact more effectively with their devices.

In contrast, a printer and a speaker are considered output devices, as they take information from a computer to produce a physical outcome (printouts) or audio output, respectively. A microphone is primarily used as an input device for audio capture, but in the context of this question, the switch array stands out as specifically designed for user input commands within a broader range of assistive technologies.
