Have you seen a colored QR?
«A person with visual disability I would have to be able to read a QR code«. A solution arose from this problem and that is precisely what those colored QR codes that you can see on food, transportation, etc. are for.
The technical name for these visual signals is NaviLens. These have the same purpose as a traditional black and white QR: to take us to a source of information, but they also have a series of advantages over them. First of all, users They do not need to know precisely where they are placedsimply scan with your mobile camera and obtain the necessary contextualized information.
Another advantage is that this system allows read from 12 times further than traditional QR and barcode, about 15 meters, in addition to being able to be scanned really quickly thanks to the combination of colors and shapes that make them up. It also means that they can be read in worse conditions than traditional ones, with a wide angle up to 160º and in all light conditions, in addition to being able to be read without having to focus. something essential for people with visual disabilities.
An app to “see” the world
These NaviLens codes They can be read with a specific application that visually impaired people can install on their smartphone so that the camera of their mobile phone acts as a guide and indicates what is in the world around them but they cannot see. NaviLens colored QRs help make cities smarter and more inclusive.
The capabilities of this code allow users interact in a simpler and more accessible way with your environment in places such as subway stations, bus stops and museums or public buildings. When using the camera through the app, Navilens reports the distance at which the tag is. In addition to the distance, it also indicates the angle of inclination of the label and can even detect many simultaneous labels, presenting them comfortably to the user.
If until now you have not wondered what these colored QR codes are, you may not know their origin either. Are created by the Murcian company Neosistec, following the advances of the Mobile Vision Research Lab of the University of Alicante. They are available every day in more and more places, from the New York Metro to those in Madrid and Barcelona, the Murcia tram, the Almudena Grandes-Puerta de Atocha Station in Madrid, hospitals and other public services. Little by little, many food companies are also betting on its inclusion so that nutritional information is available to consumers even if they have visual disabilities.
