When acting as a sighted guide for a person who is Deafblind, follow the usual sighted guide procedure, but instead of verbally offering your assistance, you can initiate the greeting by lightly touching the person’s hand or shoulder. It’s important that you maintain contact until your presence is acknowledged. Otherwise, the other person may think your touch was accidental.
It is also important to identify yourself quickly and offer assistance in a clear and concise manner. If you don’t know the person’s preferred communication method, you can try the print-on-palm method, which is both easy to use and generally understood by people who are Deafblind. To use this method, print large capital letters onto their palm with the tip of your index finger, pausing between words.
