Eyegaze EdgeOn our blog, naturally we focus on eye tracking technologies that assist disabled people. After all, eye tracking is helping so many people live more fulfilling lives. However, eye tracking isn’t the only assistive technology available to those living with disabilities.


Depending on a patient’s specific condition, certain assistive technologies – or even a combination of two or more of them – can help them to communicate with loved ones, to access information online, and to move around during their daily routines.


Here are several assistive technologies that are improving people’s lives every day:


Single-switch access


If people have very limited mobility, a single-switch access device might be a good option as well. Even if the user can move only his or her head, for example, the switch can be placed to the side of the head so the user can click it with head movements. Special software on a computer interprets this head clicking, allowing the users to navigate the web. This type of system can be enhanced with auto-complete features for further ease of control.


Sip and puff switch


This assistive device works similarly to the single-switch technology. Using this device, a person can control their breath actions to communicate on/off signals to software on a computer or mechanisms on a wheelchair. Combining this hardware with a variety of software applications can help create a custom system for the user’s particular needs.


Voice recognition software


If a patient is able to speak clearly, another option for computer use is to install software that allows him or her to control the computer by speaking. However, some people with motor disabilities (such as cerebral palsy) may have difficulties speaking so the software recognizes them. If that is not the case, voice recognition software can help people with disabilities surf the Internet, use email and other online tasks.




Eye tracking devices help individuals with no control, or only limited control, over their hand movements. Eye trackers follow the movement of the eyes to allow the person to navigate the web and to type on custom screens. People living with a number of disabilities and degenerative diseases are benefitting from eye tracking technology, including patients with ALS (Lou Gehrig’s disease), multiple sclerosis, brain injuries, muscular dystrophy, cerebral palsy, spinal cord injuries and more. Eye tracking devices allow users to use the power of their eyes to communicate with the world.
