AAC Mobile Technology & Apps for AAC 3 — Questions and Answers
Question 1: Which of the following AAC apps uses a word-based (rather than symbol-based) interface and is specifically designed for literate users with ALS or similar conditions?
- Proloquo4Text (Correct answer)
- TouchChat HD
- LAMP Words for Life
- Snap Core First
Correct answer: Proloquo4Text
Proloquo4Text is a text-based AAC app with word prediction designed for literate individuals who prefer typing over symbols.
Question 2: Eye-gaze technology used with tablet AAC systems relies primarily on which hardware component?
- Infrared cameras and LED illuminators (Correct answer)
- Accelerometer
- Bluetooth antenna
- Capacitive touchscreen
Correct answer: Infrared cameras and LED illuminators
Eye-gaze systems use infrared light and cameras to track pupil position and translate gaze direction into AAC selections.
Question 3: A user's AAC app has a feature called 'Partner-Assisted Scanning.' In this method, who controls the scanning pace?
- A communication partner verbally or physically cues through options (Correct answer)
- The device scans automatically at a set interval
- The user's eye gaze controls the scan speed
- A Bluetooth switch controls the rate
Correct answer: A communication partner verbally or physically cues through options
Partner-assisted scanning involves a communication partner naming or pointing to options while the user signals their selection.
Question 4: Which AAC app feature allows a clinician to remotely update vocabulary pages without physically accessing the user's device?
- Cloud synchronization / remote access portal (Correct answer)
- Bluetooth pairing
- NFC tag integration
- Offline caching
Correct answer: Cloud synchronization / remote access portal
Remote access portals allow SLPs to update vocabulary on a user's AAC device from a different location via cloud sync.
Question 5: LAMP (Language Acquisition through Motor Planning) is an AAC approach that emphasizes which principle?
- Consistent motor patterns for words to build automaticity (Correct answer)
- Alphabetical symbol organization
- Fringe vocabulary before core vocabulary
- Visual scene displays over grid-based layouts
Correct answer: Consistent motor patterns for words to build automaticity
LAMP uses consistent, unchanging motor patterns so that word access becomes automatic and requires less cognitive load over time.
Question 6: A therapist notices that a child's AAC app produces speech output that sounds robotic and is difficult for peers to understand. Which intervention is MOST appropriate?
- Change to a higher-quality human-sounding synthetic or recorded voice (Correct answer)
- Reduce the number of vocabulary pages
- Disable speech output and use visual-only mode
- Increase button size
Correct answer: Change to a higher-quality human-sounding synthetic or recorded voice
Voice quality significantly affects social acceptance; switching to a more natural-sounding voice improves peer interaction and communication acceptance.
Question 7: Which iOS setting allows an AAC user with limited hand mobility to activate screen functions by resting a finger without pressing?
- Touch Accommodations – Tap Assistance (Hold Duration) (Correct answer)
- AssistiveTouch floating menu
- Zoom magnification
- Color filters
Correct answer: Touch Accommodations – Tap Assistance (Hold Duration)
Touch Accommodations with Hold Duration allows a touch to register after the user holds their finger still, reducing accidental activations.
