The Assistive Technology Continuum

Although the official definition of AT describes any technology that can help someone with a disability, many people only associate AT with sophisticated computer-based, electronic devices.  It is important to realize these are not the only types of AT devices that are effective. To help, AT solutions are described by their place on a "continuum" consisting of No-tech, Low-tech, Mid-tech, and High-tech devices. A device's place on the continuum relates to its technological sophistication and complexity, as well as the level of technical training needed to use the device (Roy, 2003; Weiland, 2003). The device's cost is also typically a reflection of the device's place on the continuum. The following is a description of each step along the AT continuum.

The continuum was created to remind AT providers to first approach possible no-tech, low-tech, and mid-tech options before recommending high-tech solutions. Ideally, following an initial evaluation, the AT provider would begin by exploring no-tech options and from there, work up the continuum until an ideal person-technology match is achieved. Not only will this ensure the AT user will be matched with the ideal functional AT solution, but it also nearly guarantees the most cost-effective solution.
