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.

Claims

1. A mobile device comprising:

a display;

a physical camera communicably coupled with the display;

a processor; and

a memory coupled to the processor, the memory storing instructions, which when executed by the processor, cause the mobile device to perform operations including;

displaying a map view on the display, the map view including a set of map objects corresponding to a location within a map from an initial virtual position of a virtual camera;

receiving user input specifying a 3D mode that uses the physical camera;

in response to the user input, capturing one or more first images of a physical environment within which the mobile device resides using the physical camera;

determining an initial position of the physical camera in the physical environment using the one or more first images;

specifying a set of physical positions of a set of 3D objects of the map relative to the initial position of the physical camera, the set of 3D objects corresponding to the set of map objects;

capturing one or more second images of the physical environment within which the mobile device resides using the physical camera after movement of the mobile device;

determining a current physical position of the physical camera with respect to the initial position based on the one or more second images;

determining an updated virtual position of the virtual camera based on the current physical position of the physical camera;

rendering a map image of the set of 3D objects based on the updated virtual position of the virtual camera; and

displaying the map image on the display.

2. The mobile device of claim 1, further comprising:

one or more sensors, wherein the current physical position of the camera is further determined based on one or more measurements from the one or more sensors.

3. The mobile device of claim 2, wherein the one or more sensors include at least one of:

an accelerometer, a gyroscope, and a compass.

6. The mobile device of claim 1, further comprising:

an orientation sensor, and wherein the operations further include;

determining an angular change between the initial position of the physical camera and the current physical position of the physical camera using the orientation sensor;

using the angular change to determine the updated virtual position, thereby rotating the virtual camera.

7. The mobile device of claim 1, wherein the operations further include:

comparing the one or more first images to the one or more second images to determine a movement vector relative to the initial position of the physical camera,

wherein determining the updated virtual position of the virtual camera based on the current physical position of the physical camera includes;

applying the movement vector to the initial virtual position of the virtual camera.

8. The mobile device of claim 7, wherein determining the updated virtual position of the virtual camera based on the current physical position of the camera further includes:

scaling the movement vector before applying the movement vector to the initial virtual position of the virtual camera.

9. The mobile device of claim 1, wherein displaying the map image on the display includes overlaying the map image onto the one or more second images obtained from the physical camera.

10. A method of providing a view of a map on a display of a mobile device, the method comprising performing, by the mobile device having a physical camera communicably coupled with the display:

displaying a map view on the display, the map view including a set of map objects corresponding to a location within the map from an initial virtual position of a virtual camera;

receiving user input specifying a 3D mode that uses the physical camera;
