HP Adding 3D Motion Technology to Computers Company teams with Leap Motion By Newser Editors and Wire Services Posted Apr 16, 2013 2:11 PM CDT 0 comments Comments The Hewlett-Packard Co. logo is seen outside the company's headquarters in Palo Alto, Calif. (AP Photo/Paul Sakuma) (Newser) – Leap Motion says its 3D motion controllers will be included in some computers from Hewlett-Packard this year. The Leap Controller tracks people's fingers and hand motions as they gesture, swipe, and point at their computer screens. Applications developed for it let people control games, work on office tasks, paint pictures, or design 3D objects. At first, the controllers will be bundled with PCs and other devices from Hewlett-Packard. But Leap said the companies plan to eventually integrate the controllers and Leap's software more deeply into HP products. The move comes as PC sales are declining as people and businesses are moving on to smartphones and tablet computers.
