Just last week, I walked across 9 train carriages on the platform looking for an empty seat. By the time I hit the 6th carriage, sweat was fiercely dripping from my forehead. Holding luggage in both hands, the weight on my arms bore a terrible sensation. I let go of my hopes and boarded the train at the 9th carriage.

It was at this moment that the conductor lady approached me with great satisfaction. "It appears that your eyes have deceived you this time", she announced to me. "Look beyond the young couple in the second row, the old man sitting by the window had closed the blinds, and obstructed your view into the carriage," she said. "However, the aisle seat next to him is, in fact, vacant. Please go ahead to claim that seat if you so desire."

And so I did... not. Indeed, a wonderful story if it had been the case. Wouldn't it be great to know where the empty seats are in times of need like this? Well, today we have a solution.

What it does

Pressure sensors are placed on seats, and the activated sensors are displayed on a webpage to inform customers about the occupied seats. Our design offers a general solution to the seating problem, and this technique can be applied in a great number of situations.
