Even if the group is mixed, the technology can identify whether onlookers are children or adults. If they’re adults then maybe a wine ad could run whereas an advertisement for toys might play for kids.

"It's like a survey or research," said Saked Gupta, a software engineer for Samsung. "The [advertiser] wants to do some initial research and they want to figure out... whether [the audience] likes this ad or not."

Gupta worked on the development of the software that runs the system, but wouldn't detail how it distinguishes between men and women or children and adults, citing proprietary information concerns. He said it takes about two seconds to identify the age and gender of the onlooker and will gather data about anyone within a few meters of the cameras.

Samsung plans to release the technology worldwide in November.
