Any-Tech Assistive Devices for Vision Impaired Users
This article explores how assistive technology opens doors and unlocks potential for people with visual impairments. It presents a list of assistive devices for the blind and visually impaired, discusses assistive technology for low vision users, examines cutting-edge devices to help blind people, and addresses real-world obstacles to equal access.
Accessibility in Action, Assistive Technology, and Why They Matter So Much
Accessibility at its most essential is the philosophy of intentionally planning for and implementing the fullest possible usability, for as many interfaces and environments as possible, to include the widest possible range of users.
Accessibility is also the practice of designing products, services, and environments to be usable by people with different abilities and needs. This concept is crucial in creating inclusive spaces and solutions that can be utilized by everyone, including people with disabilities. Accessibility can be applied in physical and digital environments.
For businesses and organizations concerned with bottom-line benefits, it’s a shot in the arm, boosting reputation, expanding audiences, and helping avoid sticky legal and financial situations. It is wisest to bake in access at the earliest possible point, making it a part of planning rather than setting yourself up for costly fixes down the line.
When we make technologies, information, and physical spaces increasingly accessible, more individuals are able to join in education, employment, public services, and leisure activities, and participate fully in society. Accessibility is a commitment to diversity, and a recognition of the fact that everyone, regardless of their abilities, should have equal opportunities to engage independently with the world around them.
Why is accessibility so important? Because everyone deserves access to information, experiences, and the tools they need to thrive. Accessibility is not an act of charity; it's an invaluable investment in building a more equitable and inclusive society where everyone can contribute their unique talents and perspectives.
What is Assistive Technology?
Assistive technology (AT) refers to a broad array of physical and digital tools, devices, and software specifically designed to aid people with disabilities in performing tasks that might otherwise be difficult due to their impairments. It can also refer to low-tech or no-tech tools, as well as tools and devices that have been adapted to work in ways that offer equitable access to people with disabilities. From screen readers, magnifiers, and refreshable Braille displays for users with visual impairments, to communication aids for individuals with speech challenges, to thought-controlled prosthetics for people with mobility impairment and paralysis, assistive technology is an integral component in bridging the gap between an individual's capabilities, and the demands of their environment; using AT properly means greater independence, participation, ease of use and enjoyment for people with disabilities.
Vision Loss & Blindness: Guided by Stars Unseen
For over 2.2 billion people on our planet, the world around them unfolds differently. They see with their minds more than with their eyes. Blindness and visual impairment are not conditions that most people would choose to have, but many people with these disabilities are truly impressive human beings. They’re people we might aspire to emulate: resilient, determined, creative problem solvers. Without romanticizing or glossing over the difficulties people can face due to vision impairment, it is true that over the ages, along with unhelpful or fearful associations, vision loss has also symbolized a parallel heightened acuity of other senses: hearing, touch, smell, and even a deeper self-knowledge or spiritual understanding. People today may or may not have any convictions at all regarding theories of prophetic visions or a spirit world, depending on their individual philosophies. Science does support the idea that other senses, including bodily sensation and emotional perception, can be heightened when vision is lost. What we can all agree on is that there are many ways to perceive our environments that aren’t based on senses like sight.
The diverse and often fascinating beliefs about blindness across cultures and throughout history present a valuable background and some context for how we in modern times relate to vision loss, and to people who have visual disabilities. Of course, that’s far from the whole story: it’s an outsider’s perspective. To really begin to comprehend what it means to live with blindness or vision loss, the best person to ask is someone who has that disability.
A Runner’s Tale: Achieving Her Vision
Legally blind from the age of 9 as a result of Stargardt's disease, American athlete and Paralympian Marla Lee Runyan’s parents were told by an examining doctor that she would never be more than a C student at best. Her response was combative energy, rather than despair. “I was so mad,” Runyan said. “I was going to spend every day proving (the doctor) was wrong.” She went on to rise far above anyone's naysaying expectations, competing in two Olympic games, winning gold in the Pan-American Games, holding United States and global records while competing fiercely against world-class fully-sighted runners.
At a visual disability advocacy organization’s centennial celebration event, Runyan stated, “Support means more than just saying, ‘I know you can do it.’ Real support means saying, ‘I’ll help you do it, and I’ll show you how.’”
So let’s talk about how.
Marla Runyan’s “top three” recommendations for people facing blindness and visual impairment are:
- Keep A Winner’s Attitude
“You are going to be able to figure this out. You will succeed, and that power of positive thinking approach becomes a ‘self fulfilling prophecy’.”
Runyan is also quoted as saying, “Not only could I keep up with sighted kids, I could excel. I have an intense competitiveness that was always in me.” She pushed herself not only to run, and not only to compete in the Paralympics, she ran against users without disabilities, athletes at their peak. That kind of powerful inner drive can’t be taken for granted, but it can be encouraged. It may grow as individuals with disabilities fight unavoidable battles for access and engagement.
- Find Your Best Assistive Tools
Runyan’s top assistive tech tools are her Apple iPhone and Mac, with iPhone’s Siri using voice recognition and Mac’s VoiceOver screen reader acting as a “personal assistant.” Without these tools, she avers, “I would not have my Masters degree.”
Assistive tools can be as low-tech and fundamental as grocery delivery. Runyan used to memorize items and their locations when food shopping. Delivery services made the whole experience doable. When we find, collect, and utilize the right tools to optimize accessibility and make our lives more manageable, from bottom-line basics like online grocery shopping to advanced adaptive technology, we’re on the right track.
- Develop Support Circles, Build Community
Marla Runyan turned herself into the runner and the winner she knew she could be. She didn’t do it alone: her parents advocated for her as a child. Now, leveraging the skills she learned as part of overcoming society’s low expectations, she’s advocating for support and success herself, for other people with blindness and visual disabilities.
Support and community operate in more than one direction. “Chances are, if it’s not you who is going to have vision loss, someone in your family, or a close friend will. We’re all interconnected and we become stronger as a community if we help and support one another,” she said. That’s how community should work: the connections we build when we guide and assist others can often double back later to encourage and aid us when we need it.
Whether we ourselves have a visual disability, if we are assisting someone who is blind or visually disabled, or if we are just operating on general principles of human decency, we can offer support in ways that people with or without disabilities can use and will appreciate. Real support, as Marla Runyan shared, sounds like “I’ll help you do it”. That’s infinitely more valuable than a well-wish or a high-flown platitude. When active support is paired with clear-cut “I’ll show you how” guidance, that’s a winning one-two combination. We can all share support and community to help each other create paths to success, regardless of ability.
Currently the Assistant Director of Digital Accessibility at New York’s Syracuse University, and a former teacher at Perkins School for the Blind, Helen Keller’s alma mater, Marla Runyan continues to put into practice her personal ethos of smart, supportive success, for herself and her communities. She is also a champion of sports equity as well as an advocate of digital accessibility, having contributed to the W3C Accessibility Guidelines Working Group as an Invited Expert.
Assistive Technology for Visually Impaired Individuals: Adaptive Tools for a More Accessible Life
Assistive technology (or AT) has been steadily revolutionizing the lives of blind and visually impaired individuals, reinforcing their ability to navigate both the physical and digital world independently with greater ease of access.
From the simple white cane to high-tech cutting-edge “smart” glasses, assistive technology for blind and visually impaired individuals comprises a vast range of tools and devices designed to address the unique challenges they face. In terms of physical accessibility, low-tech or no-tech tools like canes and guide dogs, and mid-tech or high-tech tools like electronic travel aids can serve to make navigating surroundings safer and more assured for blind people, adding to their self-confidence and autonomy, and expanding their mobility.
In the digital sphere, accessibility tools including screen readers, text-to-speech software, and specialized keyboards are helping open unrestricted paths for blind and visually impaired individuals to connect to information and communication, adding new or better adaptive access to websites, documents, and online platforms.

From smartphones narrating surroundings to refreshable Braille displays translating text, these tools offer adaptive ways to navigate daily life, pursue education, and achieve goals. Let's explore the dynamic landscape of AT, where innovation is breaking down barriers one device at a time.
A Global Perspective on Visual Impairment
There’s more to understanding blindness and its impact than just the bare numbers. But statistics can help us begin to grasp the sheer volume of people who are dealing with low or no vision and attendant difficulties.
Nearly 30% of the human population worldwide experience some form of vision impairment, according to the World Health Organization (WHO).
At least 1 billion (or nearly half) of these cases could have been prevented or are yet to be addressed.
About 1.8 billion globally are estimated to be affected by presbyopia, a common aging-related vision condition.
90% of people with blindness live in low- and middle-income countries.
Challenges Faced by People with Visual Disabilities
While the loss of sight itself presents significant challenges, individuals with visual impairments often face many additional roadblocks in their daily lives as a result of their blindness or low vision:
