20130091462 | MULTI-DIMENSIONAL INTERFACE - A device can display content on a page associated with a dimension. A user can adjust an orientation of the device to adjust a displayed orientation of the page, enabling pages for additional dimensions to be displayed. A user can select one of these dimensions, and adjust an orientation of the device to enable the user to access content for the selected dimension. The change in orientation can be a tilt or flick of the device in a first direction to select a dimension, and then a user could tilt or flick the device in another direction to view pages, sub-dimensions, or other groupings of content among that dimension. Such an approach can enable a user to quickly locate content corresponding to a sub-dimension without having to scroll down a long page of content or otherwise manually navigate to specific content. | 04-11-2013 |
20130258117 | USER-GUIDED OBJECT IDENTIFICATION - A user attempting to obtain information about an object can capture image information including a view of that object, and the image information can be used with a matching or identification process to provide information about that type of object to the user. In order to narrow the search space to a specific category, and thus improve the accuracy of the results and the speed at which results can be obtained, the user can be guided to capture image information with an appropriate orientation. An outline or other graphical guide can be displayed over image information captured by a computing device, in order to guide the user in capturing the object from an appropriate direction and with an appropriate scale for the type of matching and/or information used for the matching. Such an approach enables three-dimensional objects to be analyzed using conventional two-dimensional identification algorithms, among other such processes. | 10-03-2013 |
20130342672 | USING GAZE DETERMINATION WITH DEVICE INPUT - A computing device, in a locked operational state, captures image information of a user which is analyzed to determine the direction of the user's gaze. When the user's gaze is determined to be substantially in the direction of the device, a predetermined input from the user, such as a tap or a voice command, will provide the user with access to at least some functionality of the device that was previously unavailable. If, however, the computing device detects what appears to be the predetermined input, but the user's gaze direction is not in the direction of the device, the computing device will remain in the locked operational state. Therefore, in accordance with various embodiments, gaze determination is utilized as an indication that the user intends to unlock at least some additional functionality of the computing device. | 12-26-2013 |

For example, some panoramic images may be associated with inaccurate orientation (or location) information or simply no orientation information at all. In this regard, a user may be provided with the ability to add or adjust the orientation of a panoramic image. The panoramic image can be projected onto a plane using stereographic projection and displayed relative to its location (and orientation, if available) on a map. This can allow a user to quickly identify inaccuracies and to make adjustments or corrections. | 02-19-2015 |
20150189188 | USER-GUIDED OBJECT IDENTIFICATION - A user attempting to obtain information about an object can capture image information including a view of that object, and the image information can be used with a matching or identification process to provide information about that type of object to the user. In order to narrow the search space to a specific category, and thus improve the accuracy of the results and the speed at which results can be obtained, the user can be guided to capture image information with an appropriate orientation.

20150287316 | Encoding Location-Based Reminders - Systems and methods for encoding location-based reminders are provided. Data indicative of a request for a location-based reminder can be received. The data indicative of the request can include data indicative of a user placement of a reminder in a visual representation of the geographic area, such as an image captured of the geographic area or a visual representation of the three-dimensional model of the geographic area. A selected location within a three-dimensional model of a geographic area can be identified based on the data indicative of the user placement of the reminder. Three-dimensional geographic coordinates corresponding to the selected location can be determined using the three-dimensional model and associated with the location-based reminder. The location-based reminder can then be triggered based at least in part on signals indicative of user position and/or orientation in the geographic area. | 10-08-2015 |
20150301695 | PROVIDING A THUMBNAIL IMAGE THAT FOLLOWS A MAIN IMAGE - The technology relates to selecting and displaying images captured at different points in time. As an example, a user of a computing device may view a first street level image as viewed from a particular location and oriented in a particular direction. The user may select other time periods for which similar images are available. Upon selecting a particular time period, a second street level image may be displayed concurrently with the first street level image, wherein the second street level image was captured on or around the selected time period. If the user changes the perspective of the first image an automatic change in perspective of the second image may occur. | 10-22-2015 |
20150310596 | Automatically Generating Panorama Tours - In one aspect, a request to generate an automated tour based on a set of panoramic images is received. Each particular panoramic image is associated with geographic location information and linking information linking the particular panoramic image with one or more other panoramic images in the set. A starting panoramic image and a second panoramic image are determined based at least in part on the starting panoramic image and the linking information associated with the starting and second panoramic images. A first transition between the starting panoramic image and the second panoramic image is also determined based at least in part on the linking information for these panoramic images. Additional panoramic images as well as a second transition for between the additional panoramic images are also determined. The determined panoramic images and transitions are added to the tour according to an order of the tour. | 10-29-2015 |
