Abstract: Some embodiments of the invention provide several novel methods for generating a navigation presentation that displays a device navigating a route on a map. The method of some embodiments uses a virtual camera that, based on detected changes in the navigation context, dynamically modifies the way it captures portions of the map to produce different navigation scenes in the navigation presentation. To generate the navigation scenes, the method of some embodiments (1) identifies different sets of attributes that describe the different navigation contexts at different times during the navigation presentation, and (2) uses these different sets of attributes to identify different styles for operating the virtual camera. In some embodiments, the method uses an identified style to specify the virtual camera's positional attributes, which, in turn, define the portions of the map that the virtual camera identifies for rendering to produce several navigation scenes for a period of time (e.g., until the navigation context changes, or until the navigation presentation ends when the navigation context does not change again). During the navigation presentation, each time the navigation context changes, the identified set of attributes may change. This change, in turn, may cause the method of some embodiments to select a new style for operating the virtual camera. When the style for operating the virtual camera changes, the method of some embodiments modifies the way the virtual camera captures the portion of the map to render.

Abstract: Various embodiments of the disclosure pertain to an augmented or virtual reality interface for interacting with maps displayed from a virtual camera perspective on a mobile device. Instead of manipulating the position of the virtual camera using a touchscreen interface, some embodiments allow a spatial location of the mobile device to control the position of the virtual camera. For example, a user can tilt the mobile device to obtain different angles of the virtual camera. As another example, the user can move the mobile device vertically to change the height of the virtual camera, e.g., a higher altitude above the ground.
