Freedom is most significant for any individual, and innovation plays a vital role in helping individuals become increasingly autonomous. In spite of having numerous difficulties, we continue attempting to make it simpler.

Fremont, CA: Mostly, individuals lean toward aviation routes, it being the simplest method to commute. In any case, exploring air terminals may be a challenging assignment for visually impaired people. To help solve this issue, a Carnegie Mellon University teacher, who is visually impaired from the age of 14, has begun a navigation application, which gives turn-by-turn sound guidelines for users.

Teaming up with different scientists at the university, Professor Chieko Asakawa built up an application NavCog for Pittsburgh International Airport. NavCog works practically like an indoor GPS and enables the clients to do generally everything, for example, finding a gift shop or a bistro to meander around for quite a while. The application works with the assistance of several Bluetooth reference points that are introduced in the air terminal, and wirelessly communicates the clients' location. NavCog is publically accessible and free to download.

Other than giving sound guidelines like "walk 20 feet and turn left," the application likewise educates the clients about the stores they are passing, giving a definite sense of the surroundings and shopping choices. Things being what they are, Pittsburgh is one of the leading air terminals to offer such applications around the world. Louisville International in Kentucky had introduced a comparative app in 2017, which was made by the American Printing House for the Blind.

The most critical setback of such applications is that it requires a smartphone so as to utilize them. The blind populace comprises of older people and has a high unemployment rate, which results in numerous individuals not having cell phones, making these applications inaccessible.
