Leap Motion says its 3-D 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 3-D objects.
At first, the controllers will be bundled with PCs and other devices from Hewlett-Packard Co. Leap said in Tuesday's announcement that the companies plan to integrate the controllers and Leap's software more deeply into HP products.
The move comes as PC sales are declining quickly as people and businesses are moving on to smartphones and tablet computers.
