Dear Dr.Jorge,

I talked to my friend Venkatesh here about the project and the final goal we
are trying to achieve. He is visually impaired and uses assistive
technologies for operating computer etc. I got a wonderful feedback from
him. He is excited to use the technology and thinks that it will be very
useful. He also said that if this was implemented universally, like it can
be made compulsory for some buildings to have a Wifi network and tagged
fingerprints stored so that one could easily navigate room to room. He asked
me some interesting questions which I hadn't thought of myself-
1)What happens if two rooms are opposite to each other. Will the fingerprint
be different?
2)The application is good as a location finder but if you want to navigate
in a building then fingerprint will only be different after a certain
range...what will be that range?...also the map of the building should
already be known by the application. If the rooms are numbered in an ordered
fashion then it could easily be assessed in which way one should move to
reach the destination once you know the proximity but what is rooms are not
ordered.

One more guy suggested another application of this technology. Suppose you
have a house with multiple rooms. Now if a telephone call comes then you
don't want all the phones to ring...through wifi fingerprinting it can be
sensed that in which room you are and only that phone can be made to ring.

I know that all these will be applications once we are through with the
project it seemed very interesting to me so I thought I will share it with
you.
