What is the primary purpose of eye-controlled communication systems?

The primary purpose of eye-controlled communication systems is to assist individuals who have severe limb limitations but retain good control over their eye movements and head positioning. These systems utilize eye-tracking technology, enabling users to communicate by selecting words or symbols on a screen with their gaze. This is particularly beneficial for those who may be unable to use traditional methods of communication, such as speech or manual communication devices, due to their physical limitations.

For individuals with severe limb limitations, being able to communicate effectively is crucial for social interaction, expressing needs, and participating in daily activities. Eye-controlled communication systems bridge this gap by allowing users to engage with technology hands-free, fostering independence and enhancing quality of life.

The other options do not adequately align with the specific design and purpose of eye-controlled communication systems. For instance, minimal cognitive abilities are not a prerequisite for utilizing such systems, while individuals with auditory processing disorders primarily require different types of assistive technology. Furthermore, being completely non-verbal does not inherently indicate a need for eye-controlled systems unless accompanied by the necessary eye and head control to operate them.
