These graphs provide the user with detailed part information and explicit precedence information and are intended for detailed evaluations of particular sequences. The snapshot display integrates pictorial information into and arc and node diagram. The resulting diagram displays a series of snapshots of the assembly actions in the appropriate order. The arc and node diagram is appropriate for communicating the chronological order of the assembly.
Abstract diagrams communicate abstract ideas, such as time, more efficiently than concrete pictures.
The display allows engineers to examine the process in detail while maintaining a global view of the whole assembly. The viewer can access higher levels of detail using the fisheye technique. When the viewer selects a node in the diagram it will expand to show that node in detail while maintaining the node within the global view by shrinking the other nodes around it. This format allows the operator to adjust the display to an appropriate level of abstraction for the task at hand. Click on a picture to see more detail.
