Assistive Technology for Visually Impaired Individuals: What to Choose and How
Last updated: June 20, 2022
Assistive technology can help improve the functional capabilities of individuals living with visual disabilities. In this article, we go through the different types of assistive technologies, their applications, and how they compare. Read on to learn about which low vision assistive technologies and high-tech visual aids might be right for your unique needs – or those of someone you care about.
What is Assistive Technology?
Assistive technology refers to products, devices, and equipment used to maintain, increase, or improve the functional capabilities of individuals living with a visual disability.
Assistive technology can refer to a more specific subset of low vision aids, although they can sometimes be used interchangeably. Low vision aids can include optical and non-optical aids that are typically not electronic, assistive technology can refer to a broad range of electronic or technology devices and technology tools. These could include electronic books, screen magnification programs, screen reading software, listening device, and even advanced head-mounted eyewear displays.
The Importance of Assistive Technology
Assistive technology promotes independence by helping individuals regain the ability to complete tasks that they were formerly unable to complete or had difficulty accomplishing.
In the case of persons who are blind or visually impaired, it can mean a lot. Read a menu at a restaurant, play with your child, go to the grocery store, move around freely, simply go about your life.
High-Tech vs Low-Tech
There is no formal differentiation between the two, but of course, low-tech generally refers to the technology that does not require any power source while high-tech usually requires a power source.
Low tech technology might include anything from a large font size book to braille, raised lines guide, telescopes, or magnifying glass.
High-tech would typically include a variety of apps from different operating systems, text to speech technology, video magnifiers, smartphones, CCTV, or electronic glasses like eSight.
Types of Low Vision Aids
There are different categories of assistive technologies based on the function that they serve. These categories include reading assistance, mobility devices, and all-in-one technologies.
Audiobooks and electronic books
When talking about audiobooks, a service like Audible will allow users to listen to a book. Electronic books, like the Kindle, allow the reader to adjust the content’s text size and the contrast of the page. A great tool for consuming information and all your learning needs.
Smartphones, tablets, and computers
Most smartphones, tablets, or any other computer screen are customizable to increase accessibility for people with different visual abilities. This also includes your tv screen. For example, users can increase the size of text, alter the colors of the screen, and use voice commands to access apps and other useful functions. On the App Store and Google Play Store, there are also downloadable apps designated for persons who are visually impaired to help them connect with accessible tools, magnify documents, screen readers, and more.
A computer program or software can assist by reading text out loud to the user, or magnifying text and images on the screen. Low vision users can also opt to buy a larger monitor or television screen to improve visibility. In addition, some websites have accessibility features tailored to doing all these things. Underline links, create high or negative contrast, give it a try, it is on our website!
Top Low vision apps and software
- VoiceOver is an industry‑leading screen reader that describes exactly what’s happening on a device, which can help persons with vision impairment to more easily navigate on-screen.
- LookTel Money Reader instantly recognizes currency and speaks the denomination aloud, enabling people experiencing visual impairments to quickly and easily identify and count bills.
- TapTapSee is designed to help persons who are blind or visually impaired identify objects they encounter in their daily lives. Simply double-tap the screen and take a photo of anything, at any angle. You’ll hear the app speak the identification back to you.
Mobility devices help individuals blind or visually impaired improve their mobility and orientation in order to accomplish their daily tasks. Current low-tech mobility devices, such as walking canes, can help people with visual impairment increase their mobility but do not help in other aspects of daily life.
All-in-one assistive technology is designed to keep mobility in mind while also enhancing vision and empowering individuals daily to live an independent life.
All-in-one Assistive Technology
All-in-one assistive technologies can help in almost all aspects of life in which vision is involved. It can serve as reading assistance as well as help with mobility. By getting technological advancements to work in favor of healthcare, people who are blind or visually impaired can gain back their overall lifestyle in an innovative way. You can think of these new types of assistive devices as a headset or a pair of electronic glasses that can stimulate your lost vision capabilities.
Ultimately, this technology strives to make life more accessible for persons with visual impairment.
Consider eSight: an FDA-approved and clinically validated device that is proven to enhance vision up to 6/6 or 20/20. eSight empowers individuals who have visual impairments to regain visual function, which can enable them to participate in activities of daily living however they wish.
Choosing the Right Assistive Device
The “right” visual assistive technology is subjective and depends on the needs of each individual.
For example, a student returning to school would require assistive technology that can help them do a wide variety of things like accessing content and reading the information present in textbooks, participate in virtual assessments, and contribute in class. A student would need assistive technology that can give them access to all the resources others can use to fulfill their learning needs.
However, older adults may desire assistive technology that enables them to connect and engage with their families and community. Playing games with friends or never miss watching their favorite show on tv.
For others, it may be that they want to improve their visual perception in order to be more active and play sports. Evidently, the right assistive device is context-dependent, keeping in mind the unique needs of each individual.
So, what do you want to be able to do?
Mobility, Reading, or All-In-One Assistive Technologies
In summary, choosing the appropriate assistive technology is case-dependent on needs, frequency of use, and freedom the individual needs when using the device.
Electronic glasses like eSight would allow the user to enhance their remaining vision and regain their independence, as they do not restrict mobility and also are helpful for a wide range of tasks. By placing a display in front of the user’s eyes paired with a high-tech camera and advanced software that stimulates otherwise lost capabilities, users can greatly improve their vision and everything that better vision would give them access to.
