  1. What is the primary function of a 'speech-generating device' (SGD) in AAC?

    Answer: To produce audible speech output to replace or supplement natural speech

    An SGD produces audible speech output—either digitized or synthesized—to allow individuals with limited or no functional speech to communicate verbally.

  2. Eye-tracking technology in AAC devices works by:

    Answer: Using infrared cameras to track corneal reflection and calculate gaze direction

    Eye-tracking AAC systems use infrared light and cameras to detect the reflection off the cornea, calculating where the user is looking to select symbols.

  3. Which display type on a high-tech AAC device changes vocabulary pages based on the user's selections?

    Answer: Dynamic display

    A dynamic display automatically changes the vocabulary page shown based on the user's navigation choices, allowing access to large vocabulary sets.

  4. A 'Big Mac' communicator is best described as:

    Answer: A single-message voice output device activated by a large button

    The Big Mac is a single-message recordable switch that plays one digitized speech message when its large, easy-to-press button is activated.

  5. In AAC, 'fringe vocabulary' refers to:

    Answer: Individualized, context-specific words that supplement core vocabulary

    Fringe vocabulary consists of individualized, topic-specific words (names, places, hobbies) that are unique to the individual and complement core vocabulary.

  6. Which factor is MOST critical when selecting switch access placement for an AAC device?

    Answer: Identifying the most reliable, consistent, and easily controlled motor movement

    Switch placement must be based on the user's most reliable and consistent voluntary movement to ensure accurate and efficient access to the AAC system.

  7. What is 'symbol acuity' and why does it matter in device selection?

    Answer: A user's ability to visually discriminate between symbols; affects symbol size and display density

    Symbol acuity refers to the visual discrimination ability of the user, which determines the appropriate symbol size, spacing, and number of items per display page.
