Bloomberg reports that Apple confirmed the purchase but reported that Apple won't discuss their purpose or plans in relation to the acquisition.
PrimeSense has been developing depth-sensing technology such as that in the new 3D Systems Sense 3D scanner, or the navigation platform Ava by iRobot or the Smart Terrain by Qualcomm's Vuforia.
In addition to the Ava, PrimeSense's 3D sensing technology, with its affordable sensors, is opening up new possibilities in robotics including letting the robot “see” their surroundings just like humans do. With the PrimeSense 3D camera system you can take a picture of something and see it in deep ways. The technology could be helpful in home consumer products as well as for various professions such as field workers, machine shops and manufacturers.
