LIVE FROM GSMA MOBILE WORLD CONGRESS 2012: Foursquare CEO Dennis Crowley (pictured) revealed his vision for the future of the location-based check-in and recommendation service at Congress.

The company is working on ways of using customers’ data to automatically alert them of places and events in their vicinity that they’re likely to be interested in.

“It’s taking all the data we have and trying to make a way to make people passively aware of all the things that are going on without having to be in the app all the time,” Crowley said.

“We’re enabling people to cut through this data stream in a way that I don’t think anyone has done before,” he continued.

The recently-launched Radar feature within the Foursquare app already provides a basic version of this functionality, but Crowley sees  it migrating to interfaces beyond phones, such as head-up displays.

 “It’s not science fiction. This is where Foursquare is going and this is a space where we’re really going to dominate,” Crowley said.

Foursquare recently passed the 15 million mark of people that have checked in using its service, with 1.5 billion check-ins having been made. “This is a big deal. This is generating a lot of interesting data points that allow us to do very sophisticated things,” the Foursquare chief added.
