Abstract: Some examples of a system for providing a visual based programming interface for developing camera-based applications may include a code editor interface, a timeline interface, a canvas interface and/or a program session interface. For instance, the code editor interface may allow a programmer to view and edit source code, the timeline interface may present application data associated with a program session in a frame by frame manner, the canvas interface may allow the programmer to view, interact with, arrange and/or annotate the application data in a visual format, and the program session interface may allow the programmer to choose application data to display in the timeline interface and the canvas interface by selecting between historical program sessions and live program sessions.

Abstract: Some implementations provide techniques and arrangements for interactive user interface operation and development. For instance, some implementations may generate a user interface data structure representing a user interface, the user interface data structure being generated based at least in part on state data and imperative programming code. Then, in response to a change in one of the imperative programming code or the state data, some implementations may update the user interface data structure and render an updated interactive graphical user interface based on the updated user interface data structure.
