Augmented reality (AR) is always an interesting technology, and it’s often used in games. What if developers were to take things one step further, and offer AR multiplayer gaming over different platforms? Qualcomm seems to be a supporter of AR, as it has launched an AR game studio, and is sponsoring a $200,000 developer challenge, and also offers a free software development kit. The company has churned out a proof-of-concept video (after the jump) that allows a Nexus One (over Bluetooth), a Nokia N900 (over Wi-Fi), and a Dell Latitude laptop to all be playing the same game together. Check out the video after the jump, and see if it tickles your interest.
