Abstract

Claims (83)

1. A computer-implemented method for determining placement of augmented reality (AR) content, the method comprising:

detecting that a transportation session has begun between a first user and a second user;

in response to detecting that the transportation session has begun, determining a first location of a first client device of the first user using an image captured by the first client device;

determining a geospatial offset of a second client device of the second user from the first client device;

determining a second location of the second client device based on the first location of the first client device and the geospatial offset;

determining that the geospatial offset has changed;

in response to determining that the geospatial offset has changed, generating an updated geospatial offset by:

determining a pause in motion in both the first client device and the second client device;

identifying a landmark in a first image captured by the first client device during the pause in motion;

causing the second client device to capture a second image of the same landmark; and

recalibrating the second location based on the relative perspective of the second image with respect to the first image, the recalibrated second location indicative of the updated geospatial offset; and

generating AR content for display by the second client device, the AR content being selected based on an orientation of the second client device and the recalibrated second location of the second client device.

2. The computer-implemented method of claim 1 , wherein determining the first location of the first client device using the image captured by the first client device comprises:

receiving, from the first client device, a rendering of the image;

comparing the received rendering to entries in a database of renderings, each entry including a rendering and an associated location; and

responsive to determining that the received rendering matches the rendering included in one of the database entries, determining that the location associated with the matching rendering is the first location.

3. The computer-implemented method of claim 1 , wherein capturing the second image of the same landmark using the second client device comprises:

prompting the second user to capture the second image of the same landmark, wherein the capturing is responsive to a user interaction relating to the prompt.

4. The computer-implemented method of claim 1 , wherein generating for display by the second client device AR content, the AR content being selected based on the orientation of the second client device and the second location, comprises:

rendering an object of the AR content for display at a relative location with respect to the second location, wherein the object is viewable by way of a display of the second client device when the orientation of the second client device is facing the relative location.

5. The computer-implemented method of claim 1 , further comprising:

determining a pose change of the second user;

in response to determining the pose change, comparing attributes of the pose change to each of a plurality of attributes that correspond to an end of the transportation session;

determining, based on the comparing, whether the attributes of the pose change correspond to the end of the transportation session; and

in response to determining that the attributes of the pose change correspond to the end of the transportation session, re-determining the second location without reference to the first location.

6. The computer-implemented method of claim 1 , further comprising:

detecting input at the first device confirming that the transportation session is terminated; and

in response to detecting the input at the first device, re-determining the second location without reference to the first location.

7. A non-transitory computer-readable storage medium storing computer program instructions executable by a processor to perform operations for determining placement of augmented reality (AR) content, the operations comprising:

detecting that a transportation session has begun between a first user and a second user;

in response to detecting that the transportation session has begun, determining a first location of a first client device of the first user using an image captured by the first client device;

determining a geospatial offset of a second client device of the second user from the first client device;

determining a second location of the second client device based on the first location of the first client device and the geospatial offset;

determining whether the geospatial offset has changed;

in response to determining that the geospatial offset has changed, generating an updated geospatial offset by:

determining a pause in motion in both the first client device and the second client device;

identifying a landmark in a first image captured by the first client device during the pause in motion;

causing the second client device to capture a second image of the same landmark; and

recalibrating the second location based on the relative perspective of the second image with respect to the first image, the recalibrated second location indicative of the updated geospatial offset; and

generating AR content for display by the second client device, the AR content being selected based on an orientation of the second client device and the recalibrated second location of the second client device.

8. The non-transitory computer-readable storage medium of claim 7 , wherein determining the first location of the first client device using the image captured by the first client device comprises:

receiving, from the first client device, a rendering of the image;

comparing the received rendering to entries in a database of renderings, each entry including a rendering and an associated location; and

responsive to determining that the received rendering matches the rendering included in one of the database entries, determining that the location associated with the matching rendering is the first location.

9. The non-transitory computer-readable storage medium of claim 7 , wherein capturing the second image of the same landmark using the second client device comprises:

prompting the second user to capture the second image of the same landmark, wherein the capturing is responsive to a user interaction relating to the prompt.

10. The non-transitory computer-readable storage medium of claim 7 , wherein generating for display by the second client device AR content, the AR content being selected based on the orientation of the second client device and the second location, comprises:
