Why teach augmented reality about gravity? I spoke with Trak Lord from Metaio’s San Francisco office about the newest improvements to their mobile AR technology. Modern smart phones come with a bevy of inertial sensors that typically are used for things like a compass function, but which Metaio can use (along with some complex algorithms) to detect which way gravity is pulling. Knowing about gravity allows Metaio’s AR to align everything it sees with a constant direction in the real world. Read More
