DETROIT -- Visitors to this year's Detroit auto show will get to play a 2016 version of "Pac-Man" -- without the ghosts.
That's how the show's organizers describe the way they're using beacons, wireless digital transmitters located around the exhibition hall that can track the movements of show visitors and communicate with them through their smartphones via Bluetooth as they wander the show floor.
The technology is growing in popularity as auto show organizers and manufacturers seek more ways for brands to interact with the throngs of spectators on a scale that the product specialists manning the displays never could achieve.
