Dear Pranav,
I had posted the email on this forum thinking that there may be
experts, who deal with different forms of disability in addition to
visually impaired. This device would be useful for those, who have
difficulty pressing remote control push button. In terms of technology
of IR based remote control, any feedback is provided by the equipment
that is being operated since it is one way communication. For example,
if one of operating a TV, IR remote device sends a message to TV to
carry out the desired function. TV does the function but does not sent a
message back to the IR remote device. In normal case it is not a problem
since persons operating the TV can see that desired function has been
achieved - e.g. volume has gone up.
In the specific case of light or fan control, the switch provides an
audible sound to confirm receiving command. So one can get an audible
feedback. In the case of deaf/blind one may have to do something more -
e.g. device listening the feedback sound and giving some other form of
feedback like vibration.
Turning pages of books to scan would be something which would need
mechanical arrangements along with scanner. It may be possible to
develop but right now we may not be in a position to take it up since it
involves mechanical arranagements.
Thanks for your feedback,
- Prabhat Ranjan

Dear Professor,
>From a blind person's perspective, I suspect that along with gesture based
control, you will need some kind of feedback mechanism to notify him that a
task has been accomplished. For example, think of a blind quadriplegic. How
can he tell if the light has been switched on?
The challenges become greater when the person is deaf blind.
As for other applications, how about opening and closing car doors? Turning
the pages of a book is important. Blind people need to scan books to read. A
device that turned pages automatically for them using gesture based control
would be very useful. This may also appeal to a lot of institutions for the
blind since they need to scan documents in bulk.
Finally, gesture based control would be very handy in the kitchen. How about
using it to control the level of heat of a gas or electric stove? What about
controlling microwave ovens?
