In automatic scanning, what must the user be able to do?

• A. Hold a switch for an extended time
• B. Wait for selection and activate at the correct time
• C. Quickly press multiple keys
• D. Move efficiently between choices without delay

Answer: (B)

In automatic scanning setups, users must possess the ability to wait for the selection and then activate at the appropriate moment. Automatic scanning involves the system sequentially cycling through options, and the user's task is to monitor these choices. The effectiveness of this method hinges on the user's timing; they need to be patient and attentive to recognize when their desired option is highlighted or indicated, as this is when they can initiate a selection. This process allows users who may have mobility impairments or other challenges to interact with devices more effectively, as it does not require fast or complex movements—just careful observation and timely activation at the right moment. The user's engagement in this process helps ensure accuracy in selection while using automatic scanning technology.
