What characteristic is associated with inverse scanning?

Inverse scanning is a scanning method typically used in assistive technology that requires a user to hold down a switch to activate the scanning process, and then release the switch to make a selection. This method can be particularly beneficial for individuals with varying levels of motor control or cognitive abilities, as it allows for a clear and distinct action—pressing to scan and releasing to confirm a choice.

In the context of assistive technology, this method is often employed with devices that support communication or environmental control, enabling users to engage with technology based on a straightforward and consistent control mechanism. Keeping the switch activated signals that the user is still assessing their options, while releasing confirms their choice. This intuitive approach helps users who may have difficulty with more complex input methods, making it easier for them to communicate their needs or operate their devices effectively.
