Assistive Devices for Blind and Low-Vision People: A Guide by Need

Assistive devices for blind and low-vision people are tools that help with one specific task, such as moving safely, reading printed text, telling apart currency notes, finding a route or sending a message. They range from a long white cane and a tactile map to a screen reader on a phone and to AI glasses that describe what is in front of the wearer. The most useful way to choose among assistive devices is to start with the daily task that causes the most difficulty, then test a device on that task before buying anything.

Key takeaways

• Assistive devices are grouped by the task they solve: moving, navigating, reading, handling money, communicating and getting AI-based help.
• Start from the hardest daily task, then test a device on that task before you buy.
• Several devices often work together. A cane for ground contact and a phone app for directions solve different problems.
• Training, language support and follow-up help matter as much as the device itself.
• SMARTON's smart glasses, the SMARTON Kit, are sold as the VI Inclusive Package at ₹19,999 one time.

Choosing assistive devices by need, not brand

Brand names change from year to year, but the tasks stay the same. A practical way to choose assistive devices is to write down three things: the place where the person needs help, the time of day when the difficulty is worst, and the moment when they feel most stuck. A person who crosses a busy junction every morning has a different need from a person who checks medicine labels at the kitchen table. Once the task is clear, the device category usually narrows itself.

The table below groups the common categories. It is a starting map, not a shopping list. Most people use two or three categories together, and a family often needs one device for travel and another for paperwork.

Mobility, navigation and reading tools

Mobility aids are the oldest and most familiar category. A long white cane gives ground contact and early warning about steps, kerbs, open drains and uneven surfaces. Some people choose a guide dog instead, which comes with its own training and care needs. Mobility training from a qualified instructor is usually what makes a cane effective, so plan for training alongside the device, not after it.

Navigation tools help with the question of where to go next. Tactile maps and models help a person build a mental picture of a place before they visit it. Talking navigation apps give spoken directions on a phone. The two work well together: a tactile map for planning and an audio app for the journey itself.

Reading is where many people feel the largest gap. Screen readers speak on-screen content aloud and work through keyboard shortcuts or touch gestures. Screen magnifiers enlarge text for people with low vision who still use their sight. Braille displays give a tactile line of text for people who read braille. OCR apps photograph a printed page and read it aloud. For a deeper comparison of screen readers and accessibility apps, see the guide on screen reader versus accessibility app.

Money, communication and everyday tasks

Handling money is a daily task that many blind and low-vision people manage by feel, using the size, texture or folding of notes. Currency identifiers and recognition apps add a second check when a note is unfamiliar or when a shopkeeper is busy. SMARTON's object, currency and text recognition feature identifies Indian notes from ₹10 to ₹2,000 and works offline, so it does not depend on a mobile data connection. The object, currency and text recognition page explains how it works.

Communication tools cover labelling, writing and time. Braille labellers mark tins, medicine bottles and files. Talking watches and talking calculators give spoken output for simple tasks. These are simple, single-purpose tools, and many people find them a useful first step because they need almost no setup. A device that suits one person may not suit another, so ask which labels and numbers matter most at home before choosing.

AI-based devices and smart glasses

AI-based assistive devices combine a camera, a microphone and speech output. They describe a scene, read mixed text, answer follow-up questions and handle voice tasks. They suit people who need information about the environment rather than one fixed answer, such as what is on a shelf or who is standing at a door. The user still needs to ask the question clearly, and results depend on lighting and on the quality of the image the camera captures.

SMARTON's smart glasses, the SMARTON Kit, are sold as the VI Inclusive Package at ₹19,999 one time. The package includes the glasses, training, onboarding and a one-year hardware warranty. The glasses are the one paid item in the SMARTON offering. The SMARTON app is free to use, with every feature included. Its features include MIRA, a voice assistant that starts with a button press and has no wake word, and SmartEye, which describes scenes and takes follow-up questions. Details of the glasses are on the glasses page.

How to pick and try a device

Use the same order each time you choose. First, name the task and the place where it happens. Second, list the devices that solve that task, from the simplest to the most complex. Third, try the device on that task with the person who will use it, for at least a few days in real conditions. Fourth, confirm training, language support and who to call when something breaks. A device that is not used after the first week has not solved the problem, however impressive it looked in a demonstration.

1. Write down the top three tasks the person finds hardest.
2. Match each task to a category in the table above.
3. Try one simple device first, and add a second only if a need remains.
4. Confirm training, language and after-sales support before paying.

Language matters as much as features. Many users read and listen best in Hindi or in a regional language, so check that the device or app speaks the language the person uses every day. SMARTON's app supports Hindi and English as primary languages, with more Indian regional languages. Glasses buyers also get a dedicated VI support team on WhatsApp and phone.

If a blind or low-vision person in your family or your programme has one task they find hardest, begin there. Test one device on that task for a week. If an AI-based tool seems right, ask for a demonstration of the SMARTON Kit before you decide.
