Abstract: One or more computing devices, systems, and/or methods for controlling an output device are provided. For example, features are extracted from data points of an object. A set of data points are identified from the data points based upon the set of data points having features corresponding to target features. Marker elements are assigned to the set of data points. A mapping structure is used to assign output indicators to the marker elements. The output device is controlled to provide output indicators assigned to marker elements as the marker elements become a current focus of the user navigation.

Abstract: Users may interface with user interfaces populated with large sets of data items (e.g., contacts, files, photos, etc.), but may be unable to quickly and/or efficiently find a desired data item. Accordingly, as provided herein, a graphical user interface, populated with a set of data items, may be presented to a user of a client device. Sensor data may be received from a motion sensing component of the client device. The sensor data may indicate a motion of the client device. A motion rate of the motion may be determined. The set of data items may be visually traversed at a scroll rate derived from the motion rate (e.g., a faster motion may increase the scroll rate and a slower motion may decrease the scroll rate). In this way, the user may efficiently scroll through large sets of data items by panning, tilting, twisting, or otherwise moving the client device.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing multi-factor authentication. In one aspect, a method includes determining that a user has successfully completed an authentication factor, determining whether a mobile device associated with the user is proximate to a computer; and authenticating the user based on determining that the user has successfully completed the authentication factor, and that the mobile device is proximate to the computer.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing opportunistic network updates. In one aspect, a method includes determining, by a queue manager on a mobile device that has a network interface, to fulfill one or more requests to upload or download data through the network interface, and in response to determining to fulfill the requests, applying, by the queue manager, one or more rules to the requests, to classify each request as a request that is to be fulfilled, or a request that is not to be fulfilled. The method also includes causing, by the queue manager, the requests that are classified as to be fulfilled to be fulfilled, or the requests that are classified as not to be fulfilled to not be fulfilled.

Abstract: A method of refreshing dynamic memory includes associating, for each refreshable memory element of a dynamic random access memory device, an indicator with the refreshable memory element. The method also includes detecting a predetermined data value being written to a memory location associated with a first refreshable memory element, and setting the indicator associated with the first refreshable memory element to a first value. The method further includes refreshing only the refreshable memory elements of the dynamic random access memory device whose associated indicators have values different from the first value, wherein refreshing does not comprise refreshing the first refreshable memory element.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for providing selective notifications. In one aspect, a method includes receiving code for a web application, the code including a reference to a native application equivalent to the web application, and determining whether to display a notification regarding the native application equivalent to the web application, then selectively displaying the notification regarding the native application equivalent to the web application based on the determination.
