There are many simple things you can do to ensure effective and productive interactions with individuals with disabilities. The following are some practical tips for interacting with persons with deaf-blindness.
A person with deaf-blindness has a greater or lesser extent of hearing and vision loss. This results in difficulties accessing information. People with deaf-blindness may be accompanied by an intervenor, a professional who is trained in tactile sign language. This sign language involves touching the hands of the client in a two-handed manual-alphabet, also known as finger spelling.
Other persons with deaf-blindness may use American Sign Language (ASL) or Langue des signes québécoise (LSQ) , or they may require small window interpreting (signing within a restricted range of vision). Some persons with deaf-blindness have some sight or hearing, and others have neither. Persons with deaf-blindness will probably let you know how to communicate with them. If you are unsure, ask.
