Disabled voters who have difficulty reading, are blind, or have dexterity problems may wish to use the ADA ballot-marking machine. This machine allows the person with visual problems to magnify the ballot or to see the ballot in contrast with white letters on a black background. The blind voter can listen to the ballot being read using a headset and cast votes by pressing buttons as directed.

The voter with dexterity problems may use a stylus (special pen) or simply use their finger to point on the screen to the name of the candidate for whom he or she wishes to cast a vote. A voter may also use his or her sip and puff device if needed.
