I think that young people who talk noisily, children and schoolchildren excursion groups on the train is noisy, but do not annoy me.

In public places, we need manners, but we can not force our policy to others.

However, I am using a train as a "study", so I think that if it is quiet, it will be helpful.

I think that it is convenient if I can predict passengers coming in from now before getting on the train.

Realizing this service is not too difficult if you link current location information service and IC card service.

The problem is

"Users who provide information to this service"

-----

As this service becomes common, we can get the common daily of "we don't have to match face with disgusting guy" (working hours are useless).

In the doctrine of Buddhism, one of the hardships of struggle of "the pain of meeting people one dislikes" is prescribed.

When this service starts, it is becoming a society in which mutually disliking people are correctly registered, like "easy" but "stiff"

When I think so, I'm so excited!
