Abstract: A graphical user interface generates a control pane and a diagram pane. The control pane graphically depicts control objects that are each associated with a different viewpoint of digital products. The diagram pane displays graphical representations based upon a user-selected control object in the control pane. In use, a hierarchical view of digital products is presented in the diagram pane. A user can select a digital product from the hierarchical view, and then graphically navigate the digital product, whereby the graphical user interface presents aspects of the digital product, represented as nodes and interconnecting lines in different views defined by the viewpoint associated with user-selected control objects available in the control pane.

Abstract: A method and apparatus for launching shuttlecocks at different frequencies, trajectories, speeds, spins, and shot types, thereby providing simulated shots for use in practice for badminton players and trainers. The shuttlecock launching apparatus having a dual pivoting launch assembly for providing various launch paths and trajectories, first and second launching wheels for imparting a forward motion to a shuttlecock, and a shuttlecock holding and transfer assembly for transferring a single shuttlecock from a holding area to a launch point near the first and second launching wheels in a controlled and consistent manner.
