Which of the following options describes "partner directed scanning" in indirect selection?

Partner directed scanning is a method used in augmentative and alternative communication (AAC) where a communication partner plays an active role in facilitating the selection process for the individual using the AAC system. This is especially useful for clients who may have severe physical impairments that prevent them from directly interacting with the device on their own.

In this approach, the partner assists by guiding choices, typically by presenting options one at a time or in groups, allowing the client to indicate their selection through non-verbal cues such as eye gaze, head nodding, or other means of signal. The partner's role is crucial because they help to interpret and respond to the client's signals, making communication possible when direct control over the selection process is not feasible.

Other options suggest modes of interaction that either rely on the client having full control (which may not be suitable for all users) or imply higher levels of technology that are not associated with standard partner directed scanning methods. For instance, using eye movements implies the client is independently making selections, while thought-reading devices do not exist within common AAC practices.
