Which of the following is not considered to be an aided communication strategy or support?

The correct answer is eye gaze because it represents a natural communication method rather than an aided strategy. Eye gaze relies on the individual's ability to control their eye movements to convey messages or indicate choices. This form of non-verbal communication does not depend on external tools or devices.

In contrast, a speech-generating device, communication board, and Braille display are all considered aided communication strategies. These tools enhance communication for individuals who may have difficulties speaking or who need additional support to express themselves. Speech-generating devices produce spoken output from input, communication boards provide visual symbols for users to point to or select, and Braille displays convert digital text into tactile dots for users who are blind or visually impaired. Each of these aids involves some form of external support to facilitate communication.
