Assistive Technology: Vision
These innovative tools encompass a wide range of solutions, from screen readers and magnification software that make digital content accessible to braille displays and electronic reading devices. Navigation aids like talking GPS systems and obstacle detection sensors have also proven invaluable.
Furthermore, the advent of smart devices and apps has opened up new horizons for visually impaired individuals, enabling them to perform tasks such as reading printed text, identifying objects, and even recognizing faces through the use of computer vision technology.
These advancements in assistive technology for vision continue to break down barriers, enabling those with visual impairments to lead more autonomous and fulfilling lives.
Types of assistive technology for vision:
Screen Readers - Screen reader software converts text and graphical elements on a computer or mobile device screen into synthesized speech or Braille output.
Braille Displays - These tactile devices provide output in Braille, allowing users to read digital content, including text, web pages, and documents. They typically work in conjunction with screen readers.
Examples:
- VoiceOver - This gesture based screen reader for iPhone gives audible descriptions of what's on your screen. When you touch the screen or drag your finger over it, VoiceOver speaks the name of the item your finger is on, including icons and text. This feature is built into most iPhone with iOS 12 or newer.
- NVDA (NonVisual Desktop Access) - NVDS supports many applications including all web browsers with the windows operating system. Support for many refreshable braille displays, including input of Braille via braille displays that have a braille keyboard. Support for multiple languages is available. Application is free.
- Actilino 3.0 - Actilino is a braille display that can write, read and send messages via smartphone or PC. Actilino is the super-compact note taker for blind users. The 16 piezo ceramic Braille cells and the silent Braille keyboard make the Actilino your reliable every-day companion. In real time, Actilino displays information in Braille for tactile reading.
Navigation Apps: These apps help with visual impairments navigate their surroundings, including public spaces and buildings.
Examples:
- BlindSquare - BlindSquare is the world’s most widely used accessible GPS-app developed for the blind, deafblind and partially sighted.
- Lazarillo - Lazarillo provides real time audio messages and alerts as you navigate, allowing you to explore any city in the world more safely and with greater awareness of your surroundings.
Other Apps to Try
Color Identifier Apps: Mobile apps like Color Identifier can help users with color blindness identify and differentiate colors by using the device's camera.
Screen Magnifiers: Screen magnification software enlarges a portion of the screen, making it easier for users with low vision to read and interact with the content.
Voice Labeling Systems: These systems allow users to record voice labels and attach them to objects, making it easier to identify items by touch.
How to get started:
Getting started with visual assistive technology involves understanding what help you need to help identify the right tools for your specific needs and learn how to use them effectively.
Then begin to match the challenge with the tool to see if it's the right fit. There are many tools for each visual impairment. Most smartphones and PC's have accessibility options that help with visual impairment.
Remember getting started with assistive technology can be a process that involves research, trial and error, and ongoing training. Assistive technology can significantly enhance your independence and quality of life if you take the time to explore, select, and master the right tools for your needs.
