Augmentative and Alternative Communication

People who are unable to speak or write can still express their ideas, wants and needs through what is called Augmentative and Alternative Communication (AAC). Sign language systems, for example, have been used for centuries while more high-tech options have become available in recent years. Craig Hospital’s specially trained speech and occupational therapists work with patients in the Tech Lab to find the communication options that work best to meet their individual needs and capabilities.

These include:

  1. No-Tech Options: tools that don’t involve technology, such as alphabet boards, eye-gaze boards, needs lists, icon boards and partner-assisted scanning.
  2. Low-Tech Options: tools that provide some verbal feedback, but are limited to a small number of pre-programmed responses. Most are basic record-and-playback devices.
  3. High-Tech Options: tools that provide the user with the ability to create novel words and phrases in addition to a wide variety of pre-programmed choices.

LOW-TECH OPTIONS

  • Go-Talk: offers different size keys and up to 34 messages. Some units have visual prompts and auditory cues to any message.
  • Step-by-Step Communicator: records up to two minutes and as many messages as you need. Button sizes vary from 2½ to 5 inches.
  • BIGmack Communicator: designed for those with visual impairments or physical disabilities, the activation buttons are five inches. Records only a single message up to two minutes long.
  • iTalk 2 Communicator: users answer questions or make choices by pressing one of two large, red and yellow buttons.
  • Talking Brix: light-weight, magnetic buttons can be placed anywhere in the room. Each pack contains three devices which can be arranged sequentially to promote learning or to help meet a person’s unique individual needs. Each button can hold one message.

HIGH-TECH OPTIONS

High tech augmentative communication devices give users the ability to create novel sounds or utterances in addition to selecting from a wide variety of pre-programmed choices. Users can access these devices three ways:

  1. Direct Selection: touching their device with their finger, knuckle or stylus.
  2. Switch Scanning: allowing their device to scan across rows of options so the user may choose the one he or she desires.
  3. Eye Gaze: using eye movements to select choices listed on a computer screen. These devices have cameras and a mouse cursor or other icon that appears where the client looks. The user makes his or her choice by staring at the item on the screen for a set amount of time.
