Telefonica picks Aurasma for AR

■ Telefonica said yesterday it has picked Hewlett-Packard’s Aurasma technology to expand its mobile advertising offerings in one of the largest deals yet in the emerging market for augmented reality. Augmented reality overlays text or graphics on images viewed on smartphone, tablet and PC screens. Aurasma was part of Autonomy, a former FTSE 100 company taken over by HP last year.
