  1. What is the primary purpose of switch access in AAC?

    Answer: To allow users with motor limitations to control AAC devices

    Switch access provides an alternative input method for individuals with significant motor impairments who cannot use direct touch or selection.

  2. Which scanning method presents items sequentially and requires the user to activate a switch when the desired item is highlighted?

    Answer: Automatic scanning

    Automatic scanning moves through items at a set pace, and the user activates a switch to select when the desired item is highlighted.

  3. In partner-assisted scanning, who controls the pace and presentation of options?

    Answer: The communication partner

    In partner-assisted scanning, the communication partner verbally or visually presents options, and the user signals when the desired item is reached.

  4. What is 'dwell time' in the context of eye gaze AAC technology?

    Answer: The duration a user must fixate on a target for the system to register a selection

    Dwell time is the calibrated fixation duration a user must maintain on a target for the eye gaze system to register an intentional selection.

  5. Which access method is MOST appropriate for a user who has controlled, voluntary movement of a single body part such as a thumb or foot?

    Answer: Single-switch scanning

    Single-switch scanning requires only one reliable, voluntary movement to navigate and select items, making it ideal when only one controlled movement is available.

  6. What does 'inverse scanning' refer to in AAC switch access?

    Answer: The user holds the switch to activate scanning and releases it to select

    In inverse scanning, the user holds the switch to keep the scan moving and releases it to make a selection, benefiting users who find releasing easier than pressing.

  7. What is the primary efficiency advantage of row-column scanning over linear scanning?

    Answer: It significantly reduces the number of switch activations needed to reach an item

    Row-column scanning requires the user to first select a row and then an item within that row, dramatically reducing total switch hits compared to scanning every item sequentially.
