When evaluating how scanning selection works on an augmentative and alternative communication (AAC) device, we focus on the mechanism by which a user makes a selection.
Option 1 suggests the user selects directly using a joystick. While direct selection is a valid access method for some AAC users, it does not describe scanning selection, which relies on selecting when the scan highlights an item rather than moving directly to it.
Option 2 states that the user uses voice commands to direct the device. Voice command control is another access method, but it does not pertain to scanning access where choices are highlighted in sequence and the user activates a switch to stop the scan on the desired item.
Option 3 describes the core concept of scanning: the device presents items in a sequence (scans through available items) and the user uses a switch to stop the scan when the desired item appears. This accurately captures scanning access and switch activation during the process.
Option 4 claims the user uses a screen reader to have choices read aloud. Screen readers read content aloud and are useful for many tasks, but this option does not describe the scanning selection process, which involves stopping a moving or cycling highlight with a switch.
Therefore, the most accurate description of scanning selection on an AAC device is the behavior described in Option 3, where the device scans through items and the user activates a switch to select when the target item is highlighted.
