Abstract: A computer device receives a session message in a group session on a social networking application. The session message includes a child application identifier corresponding to a child application. The device determines a session identifier corresponding to the group session to which the session message belongs. The device transmits the session identifier to the child application and receives from the child application a request for page data corresponding to the session identifier. In accordance with the request, the device obtains the page data corresponding to the child application identifier. The device renders a child application page in a child application according to the obtained data. In accordance with detecting a trigger event corresponding to the child application identifier on the session message, the device invokes the child application in the social networking application.

Abstract: A system may detect a quit operation corresponding to a child application. In response to detection the quit operation, the system may store, in a memory, a mapping between the child application identifier and the child application task, and suspend display of the child application. The system may generate a foreground and background switching entry corresponding to the child application, the foreground and background switching entry associated with the child application identifier. The system may display the foreground and background switching entry in a visible region of the graphical user interface generated based on a parent application. The system may detect a selection operation indicative of the foreground and background switching entry. In response to the selection operation, the system may obtain the child application task from the memory according to the child application identifier, and resume display of the child application based on the child application task.

Abstract: This document describes techniques and systems that enable autocalibration for multiple cameras using near-infrared (NIR) illuminators. The techniques and systems include a user device that uses NIR images, including dot images and flood images, captured by the multiple cameras. The user device implements an autocalibration module that normalizes the contrast of each image. Then, the autocalibration module detects dot features in the dot images and detects flood features in the flood images. The autocalibration module uses the flood features to disambiguate the dot features in the dot images. Then, the autocalibration module uses the disambiguated dot features to determine new calibration parameters for recalibration of the multiple cameras. In some aspects, the autocalibration module uses the dot images, rather than the flood images, to detect the flood features for disambiguating the dot features.

Abstract: This application relates to an application interface processing method performed at a terminal. After running a parent application on an operating system, the terminal generates, by the parent application, a common interface container by using a common resource of a plurality of child application interfaces. In response to an event of launching a first child application interface, the terminal loads an independent resource of the first child application interface in the common interface container, the independent resource including data in the child application interface other than the common resource. Finally, the terminal generates and displays the first child application interface according to the common interface container.
