Abstract:
In one embodiment, a mobile device automatically captures image frames by acquiring a real-time video sequence, selecting one or more frames from the real-time video sequence based on social network information and identity recognition, and storing the selected one or more frames in a local storage of the mobile device.
Abstract:
In one embodiment, a geo-social networking system automatically tags one or more social contacts of a first user to a photo of the first user by ranking the social contacts based on spatial and temporal proximity to the first user, and in response to the first user's selection of one or more top ranked social contacts, associating the selected social contacts to the photo.
Abstract:
In one embodiment, a first computing device determines a communication to be pushed to a second computing device associated with a user. The first computing device determines whether one or more conditions are satisfied for refraining from pushing the communication to the second computing device. The one or more conditions are based at least in part on the relevance of the communication to the user and one or more activities of the user. If the one or more conditions are satisfied, then the first computing device refrains from sending the communication to the second computing device. If the one or more conditions are not satisfied, then the first computing device sends information to push the communication to the second computing device.
Abstract:
In one embodiment, a request is received from a first user to create a location-triggered benefit that may be redeemed by a second user at a vendor and associated with a condition. The first user is not the vendor, and the condition may require that the second user go to a particular location. A record of the location-triggered benefit may be created in a database. Information may be received that the second user has satisfied the condition, and in response, the second user may be allowed to redeem the location-triggered benefit at the vendor.
Abstract:
Particular embodiments may retrieve information associated with one or more nodes of a social graph from one or more data stores. A node may comprise a user node or a concept node. Each node may be connected by edges to other nodes of a social graph. A first user may be associated with a first user node of the social graph. Particular embodiments may detect that the first user is entering an input term. Predictive typeahead results may be provided as the first user enters the input term. The predictive typeahead results may be based on the input term. Each predictive typeahead result may include at least one image. Each predictive typeahead result may correspond to at least one node of the social graph.
Abstract:
In one embodiment, a method includes accessing a social graph that includes a plurality of nodes and edges, receiving from a first user a voice message comprising one or more commands, receiving location information associated with the first user, identifying edges and nodes in the social graph based on the location information, where each of the identified edges and nodes corresponds to at least one of the commands of the voice message, and generating new nodes or edges in the social graph based on the identified nodes or identified edges.
Abstract:
In one embodiment, a method includes receiving data corresponding to a set of sensor values and one or more indicators that each correspond to one of a number of physical states of a client device. The client device includes a first and second set of sensors. The method also includes generating a number of functions that each determine a probability that the client device is in a respective one of the physical states. The determination includes correlating the set of sensor values with a corresponding physical state of the client device. A first function of the number of functions is based on sensor values of the first set of sensors. A second function of the number of functions is based on sensor values of the second set of sensors. The method also includes sending the number of functions to the client device.
Abstract:
In one embodiment, a method comprising by one or more computing devices, transmitting, from a first mobile device, a first message that includes a first user identifier corresponding to a first user of the first mobile device, wherein the first user identifier corresponds to a user account of the first user in a social-networking system, receiving, at the first mobile device, one or more second messages that includes a second user identifier corresponding to a second mobile device within a direct radio connectivity of the first mobile device, wherein the second user identifier corresponds to a respective user account of a second user in the social-networking system, and storing, at the first mobile device, information received in the second message for access by one or more applications hosted on the first mobile device.
Abstract:
In one embodiment, a computing device incorporating a camera receives an instruction associated with the camera to display an image generated by the camera in an area within a graphical user interface of an application running on the computing device. The computing device determines a width and a height of the area. The computing device instructs the camera to configure the image, in connection with its generation, for display in the area. And the computing device displays in the area the image as generated and configured by the camera.
Abstract:
In one embodiment, a request to create a note is received from a first user. The note includes a message and a first location of the first user. A note record is created of the message, the first location, and a first user-interest associated with the first user. A number of second users are identified based on second locations of the second users, and second user-interests associated with the second users. The message is sent to the identified second users. In response to sending the message, the current location of the first user is determined compared to the first location. If the first user is within a predetermined distance from the first location, a notification is sent to the first user indicating that the message has been sent to the second users.
