What bothers me is that the most important part of this project is to get a lot of existing entities to do something for the visual impaired people (e.g. put bluetooth devices everywhere, create sevices to push the information to users), and I feel this part of the project is brushed away in a "we have great ideas, surely everyone will be conviced to make them possible" attitude.
There is already realtime tracking of the train delays where I live, and it just doesn't work (regularly a train will be displayed as arriving to a station, when clearly it's not there, and 5 min after it gets rescheduled). Telling me in nice video that we'll expand this kind of experience to vuses and a lot of other things, and it will help blind people to workaround unexpected things just feels like wild fantasy.
About the other companies, Apple's doesn't advertise feel good prototypes of "boil the ocean" types of projects. They didn't come with a "wouldn't it be great if you could pay for things with our technology ? Imagine if everyone put this beacon everywhere in the world" video telling fluffy stories in advance.
They prototyped the barcode payment system in their shop, you could actually use it with existing devices, and they're pushing their NFC payment with a nationwide partner networks with working payment terminals from the get go, doing the hard work upfront.
