There's a cab in Oslo, Norway, outfitted with hidden CCTV cameras and hooked up to facial recognition software to record passengers as part of a digital campaign for online gaming company Casumo. And I bet you thought it was Big Brother watching. With the "Cab Cam," riders' expressions are secretly monitored to calculate how happy the person appears. Any time a rider is bored means money off their ride. Each receipt, complete with person's picture, gives passengers the balance of the fare as a cash-back code to redeem on Casumo.com. The printout also asks if the rider's photo and emotional journey can be published on a campaign website. The site will feature a heat map of the taxi's ride, color-coded to identify the most boring parts of the city. See how it works here, created by Perfect Fools.
