Abstract: This invention relates to navigation in a three dimensional environment using an orientation of a mobile device. In an embodiment, a computer-implemented method navigates a virtual camera in a three dimensional environment on a mobile device. The method includes: receiving orientation information of the mobile device; and orienting the virtual camera in the three dimensional environment according to the orientation information.

Abstract: This invention relates to anchored navigation in a three dimensional environment on a mobile device. In an embodiment, a computer-implemented method navigates a virtual camera in a three dimensional environment on a mobile device having a touch screen. A first user input is received indicating that a first object is approximately stationary on a touch screen of the mobile device. A second user input is received indicating that a second object has moved on the touch screen. An orientation of the virtual camera of the virtual camera is changed according to the second user input.

Abstract: This invention relates to user interface gestures for moving a virtual camera on a mobile device. In an embodiment, a computer-implemented method navigates a virtual camera in a three dimensional environment on a mobile device having a touch screen. A user input is received indicating that two objects have touched a view of the mobile device and the two objects have moved relative to each other. A speed of the objects is determined based on the user input. A speed of the virtual camera is determined based on the speed of the objects. The virtual camera is moved relative to the three dimensional environment according to the speed of the virtual camera.
