Abstract: Grid structure control techniques and systems are described that support use of a flexible grid structure and layout control. In an implementation, a grid factor graph is presented for display in a user interface. The grid factor graph is based on grid variables and grid factors. The grid factors define constrained relationships of the grid variables to each other. An edit to the constraint-based grid or a grid item of the constraint-based grid is received via the user interface. The grid factor is updated graph based on the edit. The constraint-based grid and the grid item are presented for display in the user interface by resolving the updated grid factor graph.

Abstract: A processing method for identifying data by an audio conversion device includes: connecting the audio conversion device to a first terminal; sending an identification code stored in the audio conversion device to the first terminal, and sending the identification code to a server via the first terminal, wherein the identification code is used to identify the audio conversion device; obtaining user data; uploading the user data to the server, such that the server stores a correspondence between the identification code and the user data; connecting the audio conversion device to a second terminal; sending the identification code stored in the audio conversion device to the second terminal; sending a data obtaining request containing the identification code to the server; and receiving the user data sent corresponding to the identification code in response to the data obtaining request, or receiving multimedia data matching multimedia using feature information in the user data.
