Assistive Technology for Nonverbal Autistics

Assistive technology opens up a new world of communication for nonverbal autistics. It allows them to express their desires, needs and wants in a nonverbal manner others can understand. The same technology can help nonverbal autistics improve their academic, motivation, organization and social skills. Assistive technology allows the nonverbal autistic to lead a more productive and independent life.

  1. Current Research

    • The Autism Resource Foundation states that certain types of computer assistive technology (AT) can help nonverbal autistics communicate. Traditionally, the technology has been used by disabled individuals with cerebral motor disabilities. Many of these same AT technologies are being used to help nonverbal autistics. The technologies include pointing systems that use pictures and symbols. Pointing systems are compatible with the communication cards already commonly used by nonverbal autistics.

    Communication

    • AT computer technologies using special keyboards, switches and computers help nonverbal autistics and autistics who do not enjoy verbal methods to communicate, according to the Autism Resource Foundation. These technologies are best suited for individuals who already know how to read and write. With the systems, the individual uses the computer screen to communicate. This type of AT is best suited for autistic persons who respond better to visual stimuli, as it has a permanence factor that auditory communication does not.

    Computer Hardware

    • AT hardware includes trackballs, switches and touch screens. Trackballs are easier to maneuver than a traditional computer mouse. Trackballs utilize a rolling stationary ball to control the cursor so the user does not need to move it across the mouse pad. Big button switches allow the user to interact with the computer by pressing on the button. The switch is connected to the computer through a switch interface box and the USB port. It can be programmed to act as several different functions, including the space bar, left or right mouse button, arrow keys or double click. It can also be used to move the cursor. Touch screens are usually overlays that attach to an existing monitor with clips or velcro. The touch screen is connected to the computer via the USB port. It usually comes with the software needed to control the touch screen. Users can activate different areas on the screen by touching them.

    Computer Software

    • Computer software is a valuable tool for helping nonverbal autistics communicate. AT hardware usually comes with the software needed to install and use the AT device. Generic software indicates what devices it is compatible with on the label or in the accompanying literature.

    Considerations

    • According to the Autism Resource Foundation, AT technology should meet the specific characteristics of the child. For example, some autistic children do not respond well to screens that flicker or to flashing lights. For these children, flat computer screens are a better option. Noise and other sensitivities should also be taken into consideration. Software should meet the nonverbal autistics level of learning and communication abilities. Programs that are too hard will stifle the communication process, but the programs should be challenging to facilitate new learning.
