As others have suggested, there are numerous problems with this whole 
concept on a realworld use basis:

\As this is a college project, it ends with whatever the end goal of the 
project is.  At best, it's a demonstration of potential capability.
For it to go beyond that, someone or something has to take it over.

Secondly, who is going to pay for all this?  And with so few individuals 
either benefiting or using it on a regular basis, it hardly sounds cost 
efffective -- at least right now.

Thirdly, I somehow doubt that the typical blind airport customer can 
simply be handed a gps unit and find their way.  Sounds real good, but 
they have to be able to implement the instructions in a timely manner and 
I am guessing that there would be still a lot of blind passengers 
wandering around confused and lost still requiring human intervention to 
assist them.

The concept raised by the college project is fascinating.  But just 
because it sounds exciting as theoretically it could assist greatly, 
translating it from a student college project for a course into a widely 
used real application, that's a long way off.

Hopefully, it will plant seeds of interest; but those seeds first have to 
bear  plants and fruit which could be a long time down the road.




Unforgiveness is the poison we drink, thinking it'll kill the other person.
