Keihin Electric Railway in Japan has introduced a "Smile Scan" system at 14 of its railway stations. The machine takes a picture of their employee's smiles and analyzes it for lip movements, lip curves, wrinkles, and so on, rating it on a 0 to 100 scale. The machine also gives feedbacks, such as "Your smile is getting better" or "Smile like you're happy!"
The system is designed to improve staff's customer response by giving them a more natural smile.

I have friends who visited Japan this summer, and they told me the most incredible things about this country. What they found especially remarkable was the politeness and friendliness of employees in public places, such as sales assistants or railway employees. It is, for example, standard for them to greet and take a bow when a entering or leaving a train.
And all this respectful behavior doesn't do? The smiles are not natural enough?
My students who train for sales assistants will laugh about this, when I tell them. Very heartily and naturally. No smiles to the customers if they don't feel like it. Natural smiles very seldom. One of them told me once: I wouldn't insult a customer by smiling artificially.
That's the other extreme.
No chance of implementing those scans in Austria, I'm sure.
