NAVIGATION IN A THREE DIMENSIONAL ENVIRONMENT ON A MOBILE DEVICE

摘要

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.
