French company Quividi has created a billboard that not only senses the demographics of its viewers, but records their reactions and adjusts its content to match.
Online advertisers have had the advantage of automated measurables, being able to retreive information about who is viewing their ads and when.
Their VidiReports function uses footage from cameras located to give outdoor advertisers the same information and more. The software identifies faces to give not only the gender, approximate age and attention time of viewers but also to identify their reaction to the billboard. More interestingly, there are talks of billboards which will change their content in reaction to the passers-by.
The company has been quick to state that footage from billboards is not stored and we don’t need to worry about privacy issues, but there may still be issues for the software – what if hundreds of people are walking by?

It sounds like a billboard like this would NEVER work in New York City. At any given time, there is more than a hundred people standing near a billboard.
If they manage to pull this off and perfect the technology, I think businesses will be able to find a lot of success using it.

I wonder whether this bill board would work in my city where you can find hundreds of people in the street walking
