摘要： A method for automatically determining device settings based on usage history. The method includes determining a characterization for a device operation in terms of a set of features and selecting a previous device operation having a characterization which is similar to the characterization of the device operation. The device settings which are associated with the characterization of the selected previous device operation may then be employed in performing the device operation.

摘要： An authentication scheme for unlocking a computing system may require a shortened password in some cases. For example, the computing system may be configured to determine a time that a user has been locked out of a computing device and to determine which of a plurality of time spans that the time falls within. The computing system may also prompt the user for a required password including a full password or a subset of the full password depending on the determined time span. The computing system may be further configured to display a visual indicator corresponding to the determined time span or a required password length on a visual display. A length of the required password for login may be progressively longer for each of the plurality of time spans as a time period that a respective time span covers increases.

摘要： Examples of embodiments provide systems and methods for varying the functions of an electronic device according to a physical relationship (e.g. the distance) between the electronic device and the primary user (e.g., owner) of the electronic device. The device may measure the distance using a wireless signal from a secondary device carried by or associated with the primary user. In some embodiments, the electronic device may change its functions based on its environment, in combination with the distance between the electronic device and the primary user. Environmental factors may include the device's location, the device's velocity, and the date and time of day.

摘要： Aspects of the present disclosure may provide a secure, location-based multimedia experience to users. In one example, a method includes receiving, by one or more computing devices, location information corresponding to a physical location of a user. The method may include receiving, by the one or more computing devices, personal identification information associated with the user. The method may also include authenticating, by the one or more computing devices, the physical location of the user based at least in part on the location information and the personal identification information of the user. The method may further include upon successful authentication of the physical location and the personal identification information of the user, coupling, by the one or more computing devices, a first computing device associated with the user to a video communication session.

摘要： A system and a method automatically generate video-based tests to distinguish human users from computer software agents. The system comprises a CAPTCHA generation engine, a CAPTCHA serving engine, a video clips database, and a video tests database. The CAPTCHA generation engine selects a video clip from the video clips database, and segments the video clip into multiple video segments. For each video segment, the CAPTCHA generation engine associates a plurality of related queries with the video segment, generates a video test based on the association, and stores in the video tests database. A CAPTCHA serving engine selects a video test for a user, maintaining a user trial counter for each user taking the video test. Based on the user trial counter information and the response to the selected video test, the CAPTCHA serving engine determines whether the user is a human user.

摘要： Systems and methods of organizing a collection of objects are described. In one aspect, a sequence of objects is segmented into object clusters based on: comparisons of successive object intervals to weighted measures of cluster extent; and comparisons of successive object intervals to weighted measures of cluster object density. In another aspect, objects from the collection are segmented into clusters. Context-related meta data associated with the objects and parsable into multiple levels of a name hierarchy is extracted. Names are assigned to clusters based on the extracted context-related meta data corresponding to a level of the name hierarchy selected to distinguish segmented clusters from one another. In another aspect, a sequence of objects that are segmented into clusters is accessed. Each cluster includes multiple objects arranged in a respective sequence in accordance with context-related meta data associated with the objects. At least two constituent objects representative of beginning and ending instances in the corresponding object sequence are selected for each object cluster. The selected representative objects of each cluster are graphically presented on a screen.

摘要： Metadata placeholders are used for distributed processing. The metadata placeholders are added to digital objects. The placeholders are filled with requests to perform certain downstream processing on the objects. The placeholders are at least partially empty so they can be filled in by nodes that perform the downstream processing.

摘要： Selecting from currently available television programs or other commercial broadcasts is enabled by clustering the broadcasts on the basis of program categories and by simultaneously displaying video information from all of the broadcasts. The channels through which the commercial broadcasts are received are monitored in order to detect any changes in program categorization. Thus, the clustering of the broadcasts is dynamic with respect to the number of broadcasts in the different clusters. Each broadcast is displayed as a reduced-scale presentation that is based upon the video information specific to the broadcasts. In one embodiment, at least one of the clusters can be split into sub-clusters, such as splitting a movie cluster or a sports cluster on the basis of genres. Optionally, the different reduced-scale presentations are continuously updated, other than during commercial times.

摘要： A video hosting web site receives uploaded video content and processes the video to determine ad surfaces. The ad surfaces comprise spatio-temporal regions of the video suitable for placement of advertisement such as background surfaces or other regions of low interest. The uploaded video and ad surfaces are stored to a video database that is accessible to viewers visiting the video hosting web site. When a shared video is requested, the video hosting site provides the requested video content together with the ad surfaces and advertisements. The advertisements are blended with the ad surfaces in the video at playtime so that the advertisements appear as part of the video scene. This allows the video hosting web site to present advertisements to the viewer without significantly distracting the viewer from the requested content.
