Ever go to a bar or club where the scene just wasn't right? Maybe everyone was too young, there were too many women, or the place was practically empty?

Using facial detection sensors and software, a company called SceneTap is trying to help bar- and club-goers find the right late-night scene before they leave home.

The system relies on multiple Intel AIM Suite sensors set up in an establishment, which detect faces in the bar and make inferences about their gender and age. That demographic data is then compiled and posted to SceneTap's smartphone app in real time.

The company says its goal is to help the nightlife industry optimize business. It's not interested in recognizing people in clubs, and the company insists its software isn't set up to do that. It doesn't store images or track individuals.

SceneTap is currently set up in 50 bars and clubs in Chicago, and it's looking to expand.

But what if you don't want to be detected? Your only option: Stay home.

"There's a decal right in the front entrance essentially giving consumers an opt-out choice," said Andrew Cummins, SceneTap's chief strategy officer, at a facial recognition conference held by the Federal Trade Commission in Washington last week. "If you don't want to walk in, that's completely your choice."

Because alcohol and peer pressure always lead to carefully thought-out decisions.
