Agents look at the footage and help relay what they see to the user, getting
them where they need to go. The service is typically subscription-based and
can be used at home or at work, but participating airports pay the fees for
users on site.
Louisville International in Kentucky installed an app similar to NavCog in
2017, created by the American Printing House for the Blind, a company that
develops products for the visually impaired.
Brian Charlson, with the American Council of the Blind, has been involved in
wayfinding for over 30 years and has seen a number of airports and train
stations try different technological approaches to make their spaces easier
to navigate for the visually impaired. The NavCog app, he said, is a useful
mashup of systems he's seen over the years.
He cautions, though, that the blind population is older and has a high
unemployment rate, so many don't have access to smartphones, meaning such
apps might be inaccessible.
Having options is always beneficial for the visually impaired, said John
McInerney, interim CEO of the Pennsylvania Association for the Blind.
"The apps can be very helpful," McInerney said. "The whole idea is that you
would not have to depend on a person to help you. But even today, that's
still a pretty good option."
