Which assistive technology is described as a refreshable display?

• A. Vineland
• B. Daisy
• C. PAC Mate
• D. Screen reader

Answer: (C)

A refreshable display is a dynamic output that can update its characters or symbols as the information changes, so a user can read new content without needing printed pages. In assistive tech, a refreshable Braille display uses pins that rise and fall to form Braille cells, and those pins reconfigure to show new braille as you move through text or navigate interfaces. The device known as PAC Mate is a handheld system that includes a refreshable Braille display, enabling tactile reading along with other accessibility features. This makes it the best example among the options. The Vineland is an assessment tool, not a display; DAISY relates to accessible audio books rather than a tactile, refreshable output; and a screen reader is software for speech output, not a physical display that refreshes.
