Passenger-phone interactive screens for subway ads

Japan is the country of long train commutes. I commute 2 hours every day to my work. The trains have print ads hanging on the walls and TV screens above the sliding doors that display animated ads. I watch them all the time when I'm not sitting down. I thought it would be interesting to make them interactive with passenger phones. Allow phones within a certain radius to be used as remote controls to send instructions to the TV screen.

The commercial could ask questions relevant to the product advertised and then collect and display the answers given by the passengers who will press buttons on their phones or send text messages. It can turn into a fun game. For people on long commutes it can add some excitement to the train ride.

Shoe-polish machines in the subway

I thought of automatic shoe polish offered as a new service inside each train wagon on subways. Small machines installed underneath the surface where the feet rest. Just behind where you seat there is a coin receiver that takes the service charge. Once the coin is dropped the shoe polish machine comes out and polishes your shoes. On a rainy day to work, that would be a great service to offer while you sit!
