<p>Various technologies and techniques are disclosed that enable interaction with 2D content placed on a 3D surface. The system determines where relative to a 3D surface an input device is located. If the input device is hitting a 3D surface, a hidden content in 2D is positioned so that a point representing the area hit on the 3D surface lines up with a corresponding point on the hidden content in 2D. For example, when a request is received for the input device position when an input device is detected at a location in a scene, the 3D surface is projected into two dimensions. A closest point is calculated on the projected 3D surface to a 2D location of the input device. The closest point is provided in response to be used in positioning the hidden content with the corresponding point of the 3D surface. ® KIPO & WIPO 2009</p> |
