Different computer devices for the physically-challenged have made their life a lot easier, making them face the world against all odds. I am not surprise to know that many among us are not even aware of these computer devices, which have showed a new ray of hope for millions around the world. Example of this is a device named 'Tongue Drive System', wherein a small magnet is implanted in the users tongue and the user has to move his tongue in order to move the cursor. Unlike the other parts of the body, which are controlled by brain through the spinal cord, tongue is directly connected to the brain by a cranial nerve. The cursor can also be guided by off-the-shelf trackballs and foot pedals instead of computer mouse. How about you...what are the other methods and technology that you saw in the film?

I was actually amazed when I saw the technology being controlled by the man's voice, I even thought that he was smoking.
