Over 2.2 billion people worldwide face vision challenges, says the World Health Organisation. This number shows we need visual impairment technology fast. Now, tools like screen readers and AI navigation systems are changing lives.
The American Foundation for the Blind sorts these tools into two types. General accessibility features are in everyday devices. Assistive innovations are for specific needs. For example, smartphones have voice commands and contrast settings for everyone. But, tools like Braille displays meet special needs.
New tech is making big strides in assistive technology solutions. Apps that recognise objects and tactile maps are helping people. These tools help in education, work, and social life. They open doors to a digital world for everyone.
Looking into these tools, we see tech is changing lives for the visually impaired. Next, we’ll dive into the latest devices, software, and strategies making a difference.
How Can Technology Help the Visually Impaired? Current Assistive Technologies
Modern tools have changed the game for those with vision loss. They offer solutions for digital access, mobility, and daily tasks. From screen readers to canes with sensors, these innovations help bridge gaps. They also meet accessibility standards in recent studies. Let’s look at today’s most impactful technologies.
Screen Readers and Magnification Software
Digital accessibility starts with software that changes visual content into sound or big text. These tools are key for education, work, and personal life.
JAWS by Freedom Scientific: Industry-standard Windows solution
JAWS is a top choice for Windows users. It has a big command library and works with Braille displays. It also uses AI to quickly turn scanned documents into speech.
