Helping the blind will be one of the hardest challenges for researchers, but the technology will help others, too. NavCog can be useful for people in wheelchairs. Recently, when I was travelling in New York City with a big suitcase, I couldn’t find an elevator anywhere and I had to carry the suitcase upstairs by myself. Think of the same situation for someone in a wheelchair who needs a route to avoid steps. And the elderly, too. They need elevators and maybe help finding shops or recognizing items in a store if their vision isn’t good. GPS doesn’t help when you’re indoors.
Even people without accessibility issues can benefit. Think about when you travel to a foreign country and you can’t read the signs or food labels or find a type of shop because you don’t know the language.
