IN-LINE MEDIATION FOR MANIPULATING THREE-DIMENSIONAL CONTENT ON A DISPLAY DEVICE
First Claim
1. A method of detecting manipulation of a digital 3D object displayed on a device having a front side with a display and a back side, the method comprising:
- detecting a hand within a specific area of the back side of the device, the back side having an sensor;
displaying the hand on the display;
tracking movement of the hand within the specific area of the back side, wherein said movement is caused by a user intending to manipulate the displayed 3D object;
detecting a collision between the displayed hand and the displayed 3D object; and
modifying an image of the 3D object displayed on the device,wherein the device is a 3D in-line mediator between the user and the 3D object.

Abstract
A user holds the mobile device upright or sits in front of a nomadic or stationary device, views the monitor from a suitable distance, and physically reaches behind the device with her hand to manipulate a 3D object displayed on the monitor. The device functions as a 3D in-line mediator that provides visual coherency to the user when she reaches behind the device to use hand gestures and movements to manipulate a perceived object behind the device and sees that the 3D object on the display is being manipulated. The perceived object that the user manipulates behind the device with bare hands corresponds to the 3D object displayed on the device. The visual coherency arises from the alignment of the user'"'"'s head or eyes, the device, and the 3D object. The user'"'"'s hand may be represented as an image of the actual hand or as a virtualized representation of the hand, such as part of an avatar.

15. A device having a display, the device comprising:
-
a processor; a memory storing digital 3D content data; a tracking sensor component for tracking movement of an object in proximity of the device, wherein the tracking sensor component is on a back side of the device facing away from a user; a hand tracking module for processing movement data related to a user hand; and a hand-3D object collision module for detecting a collision between the user hand and a 3D object. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)

24. An apparatus for manipulating digital 3D content, the apparatus having a front side with a display and a back side, the apparatus comprising:
-
means for detecting a hand within a specific area of the back side of the apparatus, the back side having an sensor; means for displaying the hand on the apparatus; means for tracking movement of the hand within the specific area of the back side, wherein said movement is caused by a user intending to manipulate a displayed 3D object; means for detecting a collision between the displayed hand and the displayed 3D object; and means for modifying an image of the 3D object displayed on the apparatus, wherein the apparatus is a 3D in-line mediator between the user and the 3D object. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
