QR codes are used so much these days. However, for those unable to hold a phone steady while it captures the code or for those who cannot see where the code is located, they can be inaccessible. A company, NaviLens, has developed a way to make QR codes more accessible. Once the codes are more accessible, people use a NaviLens app on their phone to detect the codes. The codes can be detected from much farther away and the phone capturing the code does not have to be held perfectly still. They are currently in use on many products as a form of identification and information, and in cities to assist with navigation. This video illustrates how it all works.
I can think of many applications for these accessible QR codes in education. For example, they could be used in science classes to enable equipment, supplies, and model identification and to supply additional instructions and information in lecture and lab. Outside of the classroom they could be used to indicate the location of stairways, elevators, and exits, to identify buildings, and to mark emergency evacuation routes.
