I use the Metro train often. Although not often to commute but I see people using it to go to work and then return home after a tiring day. If they are lucky to get a place to sit, then most often they tend to doze off.

I do not know if they pretend to doze or really do. Nor do I know if they really doze off and miss their destination. What if they had a tag on their forehead requesting the neighbors to wake him/her closer to the destination, would the neighbors oblige and fulfill their social responsibility? I do not know how people will react in Delhi and I want to find out.

Here is an experiment: Make a wearable, dot matrix LED based scrolling display mounted on a eye-band, requesting the fellow passengers to wake him/her in time for the destination being scrolled on the display. Then you wear this and pretend to sleep and see what the reaction is?

What you would need is a few small 5x7 dot matrix displays (something like this: http://www.best-microcontroller-projects.com/led-dot-matrix-display.html), driven by ATMega8, phone battery, and a few switches to create the required message.

Open for discussions on implementation of this project.
