Should we blame them or should we provide them with feedback and make them
more aware of our needs and limitations of their newly designed products and
motivate them to improve or inovate the products catering to our needs?

What I don't understand is: Why there is a desperate attempt to do
away with white cane? While this device may enhance our mobility, it
can never supstitute cane. It's the high time that forums like Access
India informs those stupid scientists that we are not so keen in
throwing our canes away.

can a blind person walk faster then using white cane with this device?
it
will vibrate in every 2-3 feets and will prompt user not to move this
side.
mainly in railway stations or bus stops.

Le Chal is a navigational device for the blind, that guides them
to their destination via vibrations in one of their shoes
Anirudh Sharma's system is called Le Chal, which is Hindi for
"Take Me There." It is intended primarily to assist users in finding
their way to specific geographical locations, although it also helps
them avoid walking into things on their way there. Sharma designed the
first prototype in January, while attending MIT's Design and
Innovation workshop in the Indian city of Pune.
The basic idea behind Le Chal is that one of the user's shoes
will provide haptic feedback, guiding the user toward their
destination by vibrating in the front, back, or on either side - a
vibration on the front indicates that they should keep going straight,
a vibration on the left side means that they should turn left, and so
on.
The user begins by entering their destination on Google Maps,
using their Le Chal-app-running Android smartphone. That phone then
communicates by Bluetooth with a LilyPad Arduino circuit board,
located in the heel of the shoe. Following the Google-supplied
turn-by-turn directions, along with locational data from its own GPS
unit, the phone gets the Arduino to activate each of the shoe's four
vibrators as needed. The vibrations start out low, but build in
intensity as the user nears points where they have to turn.
A proximity sensor in the front of the shoe also alerts the user
to obstacles, which it can detect from up to ten feet (three meters)
away.
While there is no word of Le Chal being marketed any time soon,
Sharma is planning to release the code for the app and the schematics
for the shoe, via the Arduino community. He also plans on creating a
Do-It-Yourself guide on Wikipedia, which users can update with their
own improvements to the system.
