Discussion
Examples of assistive technological devices to cater to needs of children with visual difficulties include-
(A) alternative computer input devices.
(B) braille embosser and displays.
(C) speech recognition software (speech to text).
(D) use of sign language.
Choose the correct option.
Answer: A
The examples are Only (A), (B) and (C).
Children with visual difficulties are helped by technology that replaces or supplements sight. Braille embossers print text in braille and refreshable braille displays show screen text as raised dots (B). Speech recognition software lets the child give input by voice instead of locating keys and menus visually (C). Alternative input devices, such as braille keyboards and other adapted input tools, likewise make the computer usable without relying on sight (A).
Sign language (D) is a means of communication for children with hearing impairment, not an assistive device for visual difficulties, so options that include (D) are wrong. Option C leaves out (A).
