Abstract: In one embodiment, a computing system receives an indication of current mobile device usage by a user. The user is also associated with one or more past user states that are accessible to the computing system. The computing system selects a future user state of the user based on a calculated probability of a possible future user state. The possible future user state is calculated based on the current mobile-device usage and the past user states. For each past user states, a weight based on a time delay factor is used. Based on the selected future user state, the operation of a mobile device of the user is adapted at the future time corresponding to the future user state.

Abstract: In one embodiment, a first computing server receives a message from a client computing device. The message identifies an image to be displayed on the client computing device. The message is generated by a second computing server and received by the client computing device in response to a request sent by the client computing device to the second computing server for the identified image. The first computing server determines one or more adjustment parameters based on the display capabilities of the client computing device. The first computing server creates an adjusted version of the identified image based on the adjustment parameters, and sends the adjusted version of the identified image to the client computing device for display.

Abstract: In one embodiment, one or more main processors of a device detect an event corresponding to scrolling a structured document presented in a scrollable graphical user interface of an application executed by the one or more main processors. The main processors, in response to the event, determine a first set of elements and a second set of elements of the structured document; render the first set of elements of the structured document for presentation in the graphical user interface; and cause one or more graphics processors of the device to render the second set of elements for presentation in the graphical user interface.

Abstract: In one embodiment, a computing device receives a request from a mobile device of a user for an image. The computing device determines whether the user is associated with a preferred orientation for viewing an image. The preferred orientation is determined based on the user's usage patterns with respect to a particular application of the mobile device, or to the user's interactions with a social-networking system. If the user is associated with a preferred orientation, the image is adjusted to have the preferred orientation and to match display capabilities of the mobile device sending the request. The adjusted image is sent to the mobile device for display.

Abstract: A user interface includes a tactile interface on a client device that allows users to interact with social networking system content in a manner that is optimized for touch screens and mobile devices. The tactile interface allows users to efficiently navigate the social networking system data as well as to capture new content for upload to the social networking system. New content may be captured in a way that allows the user to preview the content in-context.

Abstract: In one embodiment, a method includes accessing a base user experience (UX) including a user interface (UI) corresponding to one or more features of a computing system; determining one or more user categories based at least in part on previous interactions with the UI by a number of users; classifying, using a machine-learning algorithm, a particular user into one or more of the user categories based at least in part on current interactions of the particular user with the UI; and determining, relative to the base UX, one or more modifications to the UI based at least in part on the classification of the particular user into one or more of the user categories. The modifications to the UI modify one or more features of the UX. The method also includes applying the modifications to the UI; and providing the UI as modified for display to the particular user.

Abstract: In one embodiment, a method includes receiving first data indicating a current usage of a mobile device by a user. The method includes accessing second data associated with past user states of the user, where each user state corresponds to a temporal, spatial, or modal accessibility of the user. A future user state of the user is determined based on a weighted set of predictor functions, each predictor function comprising a machine-learned algorithm for a particular user state. The probability of each user state is based on past user states of the second data, wherein each past user state is weighted by a decay factor based on the corresponding time. One of the user states is selected as the future user state, and the operation of the mobile device is adapted at a future time to account for that future user state.

Abstract: A swim fin assembly is configured to allow changing a swim fin and reduce leg strain of a human user. The swim fin assembly includes a leg portion, attached to a foot portion, and configured to accommodate a human leg and foot of the human user. A rear support is attached to the leg portion and further attached to a rear bracket. A fin attachment bracket is connected to the rear bracket. Inserting the swim fin into the fin attachment bracket enables a user to swim with reduced leg strain.

Abstract: In one embodiment, a method includes determining, relative to a base user experience (UX), one or more modifications to one or more graphical elements of a user interface (UI) for display to a particular user. The modifications are configured to personalize the UI individually to the particular user and based on a computational determination of one or more categories applicable to the particular user.
