CES 2012: Phone-to-phone gaming and more with Alljoyn [Video]
Some times the coolest new things you see at the Consumer Electronics Show aren't gadgets or apps or even 55-inch OLED TV sets (although, admittedly, those are cool). Sometimes they're just technologies, which is what digital stereoscopic displays and gesture recognition were before they became 3D TV sets and XBox Kinect.
A good example this year is Alljoyn, an open-source software project coming out of an innovation lab run by Qualcomm. Alljoyn enables nearby users of an app to interact with each other, even when there's no local data network. Multiple people in the room can join the activity, whether it be playing a game, taking turns in the virtual DJ booth or working on an electronic whiteboard. And unlike collaborating through a congested Internet, there's little or no delay -- the users' devices are seamlessly synchronized.
The magic isn't in the short-range communications technology -- Alljoyn runs on top of Wi-Fi and Bluetooth. What's special is the ability it gives developers to quickly add proximity networking to just about any app, even if they have no expertise in radio communications. For example, it took programmers at Namco only a week to add Alljoyn capabilities to their Pacman Kart Rally game, according to Qualcomm's Liat Ben-zur.
The demos at the Qualcomm booth showed how nearby tablets, smartphones and even a tablet and a connected TV could join in games and productivity apps. Because Alljoyn connects apps, not devices, users can collaborate simultaneously with separate groups on different programs, with no overlap -- for example, working on a virtual whiteboard with one team while collaborating on a document with another.
Ben-zur said the potential uses include a wide variety of entertainment, education and business applications. The breakthrough here, she said, is that any developer will be able to make apps that can seamlessly discover and interoperate with related apps nearby. She added, "I believe this is a new Pandora's box for mobile."
