When interacting with a blind person, what is the appropriate method for communication?

When interacting with a blind person, allowing them to hold your arm is the appropriate method for communication and guidance. This technique provides a sense of security and orientation for the individual as they can follow your movements and anticipate turns or changes in direction. By holding your arm, they have a tactile reference point, which allows for more effective navigation and helps them feel more confident and in control of the situation.

This approach fosters a respectful and supportive interaction, ensuring that the visually impaired person is able to participate in the conversation and movement without feeling disoriented or anxious. The other options either do not facilitate effective communication or could potentially be disorienting or disrespectful.
