CPACC Assistive Technologies and Strategies 4 — Questions and Answers
Question 1: Which assistive technology feature allows a screen reader user to navigate directly to the next heading on a page?
- Tab key navigation
- Single-key navigation (H key) (Correct answer)
- Arrow key browsing
- Find and Replace function
Correct answer: Single-key navigation (H key)
Most screen readers support single-key navigation where pressing 'H' jumps to the next heading, enabling efficient page exploration.
Question 2: A user with essential tremor has difficulty using a standard mouse. Which pointing device would BEST reduce the impact of involuntary hand movements?
- A smaller optical mouse
- A trackball mouse (Correct answer)
- A wireless mouse
- A high-DPI gaming mouse
Correct answer: A trackball mouse
Trackball mice allow cursor control by moving the ball with fingers or palm, reducing the need for gross arm/hand movements that tremors affect.
Question 3: What is the primary purpose of a refreshable braille display when used with a computer?
- To translate spoken audio into braille output
- To provide tactile output of on-screen text in real time (Correct answer)
- To emboss permanent braille documents from digital files
- To scan printed text and convert it to digital braille
Correct answer: To provide tactile output of on-screen text in real time
A refreshable braille display uses pins that rise and fall to represent braille characters, giving blind users tactile access to on-screen content in real time.
Question 4: Which strategy is MOST effective when a Deaf user needs to participate in a real-time online meeting without an interpreter?
- Sending a written summary after the meeting
- Using automated real-time captioning (CART or auto-captions) (Correct answer)
- Providing the meeting recording afterward
- Increasing font size in the chat panel
Correct answer: Using automated real-time captioning (CART or auto-captions)
Real-time captioning converts speech to text as it happens, allowing Deaf participants to follow conversations without a delay.
Question 5: Eye-gaze technology is MOST beneficial for users who:
- Have low vision and need screen magnification
- Have no functional use of their hands or voice (Correct answer)
- Are Deaf and require visual alerts
- Have cognitive disabilities affecting reading speed
Correct answer: Have no functional use of their hands or voice
Eye-gaze systems track eye movement to control a cursor or on-screen keyboard, enabling computer access for users with severe motor impairments who cannot use hands or voice effectively.
Question 6: A user with dyslexia reports that changing the font on a document significantly improves readability. Which font characteristic is generally considered MOST helpful for dyslexic readers?
- Serif fonts with decorative strokes
- Fonts with uniform letter spacing and distinct letterforms (Correct answer)
- Condensed fonts that fit more text per line
- Italic fonts that mimic handwriting
Correct answer: Fonts with uniform letter spacing and distinct letterforms
Fonts with consistent spacing and clearly distinct letterforms (such as OpenDyslexic or clean sans-serif fonts) reduce letter confusion for many readers with dyslexia.
Question 7: In the context of assistive technology, what does 'switch access' refer to?
- Toggling high-contrast mode on a display
- Using one or more adaptive switches to control a device through scanning (Correct answer)
- Switching between multiple assistive technology applications
- Hotkeys that switch keyboard layouts for different languages
Correct answer: Using one or more adaptive switches to control a device through scanning
Switch access allows users with limited motor control to operate devices by activating one or more simple switches, often combined with on-screen scanning to select options.
