If you’ve ever been to Tokyo or any other large Japanese city, you’ll have noticed the huge variety of billboards plastering the urban landscape, often featuring the month’s most popular idol.

The sensor will detect the motion of people in front of it, and display appropriate pictures in response — “appropriate” may not be the right word for everyone, though, as the main use case demonstrated by the researchers so far is the ability to “kiss” the idol on screen. After you’ve expressed your affection for the poster and moved your head away, the girl blushes with embarrassment, for example.
