Andreea commented on Gantabya - The Talking Destination

This is a salutary initiative and it's great that it focuses on improving the life of visually impaired people in environments that are difficult for them, and also in places which are not customised for them.

It's useful that Gantabya supports visually impaired people be independent in their daily life, that it helps them not have to depend on someone else. I believe this is empowering.

At the same time, I have doubts about the technology used and the costs + difficulty of implementing the solution. Considering that 3 beacons need to be installed on each bus: how much would that cost and who would pay for it? Also, if the percentage of visually impaired people is 0.36% - would this make sense as an investment in public transport? I mean by no means that this percentage is not significant enough - but rather that maybe this would be a challenge in raising funds for implementation from the public/private sector.

I am wondering if there is a mobile app-based solution that would not require extra devices installed on buses/buildings? For example reaching the destination or the bus stop could be notified based on the a customised GPS-based solution. And maybe the arrival of the bus could be detected through some kind of ultrasonic sensors that can recognize the shape/type of vehicle (somehow like bats do)?

I'm not an expert in this but hope it helps.
