Qualcomm's best Augmented reality apps

In October 2010, Qualcomm launched an Augmented Reality Application Developer Challenge that asked development teams what AR apps they could make by the beginning of 2011, using the company’s new AR SDK.
From the pool of submitted applications, three winners were announced at Mobile World Congress 2011 to win cash prizes of $125,000 for first place, $50,000 for second place, and $25,000 for third place - a handsome purse.
We caught up with the head of AR at Qualcomm to see first and second place, plus another favourite to see what they were and how they worked.

Paparazzi

The top prize of $125,000 was awarded to a team of two developers from Lithuania, Paulius Liekis and Arminas Didžiokas for Paparazzi.
