The Range of Assistive Technology

AT Spectrum
Scope of AT Devices
Light Tech
Mid Tech
High Tech

The amount of technology that currently exists is impressive. Many times we also do not realize that some "assistive devices" are actually considered assistive technology. For this reason, we like to introduce assistive technology as a continuum or spectrum of sophistication.

No Tech: Simple Modifications, Inexpensive, Ready to Use, Affordable Tools
Low or Light Tech: Less Sophisticated, Easy to Learn, Readily Available, Affordable Tools
Medium Tech: May Cost More, Requires Some Training, Relatively Complicated Mechanical Devices
High Tech: Very Advanced, Needs Specific Training, May Require On-Going Support, Electronic/Digital Devices, Expensive

As we defined "Assistive Technology" previously, AT "is any item, piece of equipment, software program, or product system that is used to increase, maintain, or improve the functional capabilities of persons with disabilities.” This definition can include something as simple as a pencil grip or something as complex as a sip and puff switch activated power chair.

The "scope" of assistive technology refers to when and why we use assistive technology. Below is an expensive list of where assistive technology can assist everyone.

Communication
Seating and Positioning
Power Mobility
Manual Mobility
Mobility Aids
Assistive Listening
Vehicle Modification
Leisure/Recreation
Worksite Modification
Home Modification
Learning Aids
Environmental Controls
Vision Aids
Self Care/ADL

No Tech / Light Tech

These are items that you probably already have in your house that you most likely have used before in your life. Many people might not consider highlighters or pencil grips assistive tech, however for people with dyslexia, using various colored highlighters could drastically assist in ones ability to read and follow along with text.

Mid Tech

Medium Tech devices is a bit of a gray area, but a good distinction to categorize mid tech devices is that they require some training to use them. Typically they cost more than a light tech device and have a more limited usefulness than a higher-tech/robust device.

Examples

Switches

Accessible toys

Switch Communicators

Go Talk

High Tech

High tech assistive technology is generally very advanced and one would need training to use it to its fullest potential. It may also require ongoing technical support. Typically high tech devices are fully electronic, expensive and versatile in functionality.
