Chapter 9 Visual Impairment

There are a number of technologies that can be used for someone with a visual impairment. 

Artificial Intelligence
This is software or hardware that can make decisions that was typically only done by humans in the past. An example might be recognizing faces.

These are bumps on paper or dots on a computer screen that represents letters for a person with a visual impairment. 

Take a Picture Ask a Question Apps
These are apps that a person with a visual impairment can use to have a sighted individual describe an object for them.

GPS Apps
These are apps that will tell you your locations, describe your surroundings, and give you directions of how to find something. 

Reverse Projecting or Projecting onto an iPad or Computer
Typical when you project something it is a computer projected onto a screen. When you want to do the same exact thing onto a device, I use the term reverse projecting. This can be done to project a document onto a device for someone with a visual impairment to see. 

This is hardware and/or software that enlarges text on the fly.
