Which assistive technology would be least helpful for a student with limited mobility and dexterity?

Screen readers primarily assist individuals with visual impairments by converting text on a screen into speech or Braille. While they are essential for students who have difficulty seeing, they do not aid in improving mobility or dexterity. For a student with limited mobility and dexterity, the focus is on technologies that facilitate interaction with a computer or other devices through alternative methods.

Voice recognition software allows users to control devices and input text using their voice, which is very beneficial for someone who has difficulties with physical interaction. Adaptive keyboards can be specially designed to accommodate a variety of physical needs, making it easier for users with limited dexterity to type. Touchscreen devices can also be advantageous, as they may allow for more intuitive interaction through taps or swipes, particularly with larger buttons or customizable interfaces. In contrast to these options, screen readers do not provide the necessary adaptations for mobility and dexterity limitations, making them the least helpful in this scenario.
